What is a best kind of FTL?

1) No FTL. Regular speeds. Travel is either limited to a few close-lying solar systems, or the crew spends centuries in hybernation.
2) No FTL. Sub-lightspeed accessible. Range is large, crew doesn't hybernate due to relativistic effects.
3) Straight-up FTL. The "fuck Einstein" variety.
4) Hyperspace/Warp/Null-space. Another dimension where ship still flies.
6) Instantaineous jump. May still involve hyperspace, but anyway the ship effectively just teleports.
7) Portals/wormholes/stargates. Self-explanatory. Doesn't matter if natural or artificial, permanent or temporary.

>>54141693
Hyperspace is the worst, because it can't physically exist in our universe.

Alcubierre drives are alright.
Wormholes a best, because they are realistic and avoid most timetravel and WMD problems.

Instantaneous wormhole-based teleport drives aren't realistic, but they're a fair alternative to Alcubierre drives that remove the planet-ramming problem.

It depends on the story, really. Each one produces a different shape of society and a different shape of narrative. Sometimes I'm in the mood for Star Wars and sometimes I'm in the mood for Revelation Space, you know?

>>54141693
>No FTL. Sub-lightspeed accessible

Stop right there.

Once you cross that line, you have to acknowledge that any FTL is time travel so you can arrive at your destination before the light of an certain event and hence violate causality.

Sub-lightspeeds are cool and accesible with Pulsed nuclear engines either Orion drives or inertial confinement fusion, 30% the speed of light is not out the realm of possibility.

The problem starts when you realize that 30% speed of light is pretty much a relativistic kill vehicle, so the dynamics of war change a lot now, even inside a solar system we pretty much will see the equivalent of nukes and maybe small tactical relativistic kill vehicles to just create a few dozen miles in depth crater inside a planet as a bridgehead.

>>54141693
>hard
No FTL, unless it's bleeding edge, poorly understood, and is treated as a big deal in-setting.
>(((hard)))
Wormhole generators. Hard enough to keep the autists satisfied, but soft enough that you can have your star-hopping adventure.
>soft/space fantasy
Plothole space, especially of the Grossly Incandescent Space Hell variety. Space fantasy only: drive failures don't cause the ship to evaporate, but instead results in demonic incursion, giving players the opportunity to rip and tear.

>>54141804
You know how an asteroid can fuck up a planet? Take that asteroid, and speed it up to FTL. If you don't strictly NEED that planet, then it's the be-all-end-all of siege warfare.

>>54141804
E = mc^2 makes fast spaceships relativistic kinetic kill vehicles.

>>54141737
Unfortunately no, wormholes still violate causality if it allows for FTL.

All FTL options violate causality, period. As soon as you add a third observer who is travelling towards or away from the ship(s), it all falls apart.

There's no magic bullet around it, aside from saying that the science is wrong and inventing your own science-fantasy interpretation.

>>54142021
>Unfortunately no, wormholes still violate causality if it allows for FTL.

Yes, they do, but you can ignore that for most practical purposes by postulating a wormhole network that considers itself a universal frame of reference and avoids the easy exploits around this by Visser radiation handwaves.

>>54142012
Does that even work with the Alcubierre Drive, since the whole trick of it is that the ship is not moving at relativistic speeds, just the space-time bubble around it?

I really like Hyperspace and stargate/portal options, but then again I don't play hard scifi so realistic physics of space travel doesn't matter to me. Currently i'm waiting and stealing all these images for when Starfinder releases.

In that they use something called the Drift, a hyperspace style FTL that was created by a tech god, who is the fusion of three different technology gods (clockwork god, android god, and AI god). Whenever you use the Drift, you sometimes pull chunks of the surrounding plane into the Drift, and you can use it to get to and from other dimensions too. Which means you can be flying to a nearby star system to pick up cargo and get waylaid by an encounter with angels trying to get home, or demons stalking the flight lines between stars, or other more stranger things.

>>54142077
At >c velocities, the interface fills the bubble with amazingly excessive amounts of radiation inside and out. So if we're really using a 'hard' setting, Alcubierre drives can't approach c without self-destructing.

>>54142021
>aside from saying that the science is wrong
Except that's 100% certain.

We *KNOW* that the relativity-based model of physics is not comprehensively correct, just a useful approximation in most cases, the way Newtonian physics was before it.

The fact that we have a model of physics that depends on entirely unobserved theoretical "dark matter" and "dark energy" making up the majority of the universe in order for its preconditions to hold together at an interstellar scale means we are wrong about something fundamental.

>>54141980
>Plothole space, especially of the Grossly Incandescent Space Hell variety. Space fantasy only: drive failures don't cause the ship to evaporate, but instead results in demonic incursion, giving players the opportunity to rip and tear.


Now this I like. Perfect for an intro adventure to the campaign. Especially if it was all only known by the higher eschelon and a few scientists and hidden from general knowledge as possible conspiracy theoretics or crazy talk from religious fanatics.

>>54142178
>a model of physics that depends on entirely unobserved theoretical [...]
Reminder that the existence of antimatter was predicted by one guy being really autistic and insisting that his formula for 4d quantum wave propagation had to look pretty. I'll buy that there's some weird invisible shit until we have a better theory out there.

>>54142220
It's also great for (in works leaning more towards fantasy than space) having some space crusades, where people have the actual, physical backing of the forces they champion. Even in the less fantastic form, you could have certain favored groups just "happening" to find the most efficient paths for jump and have fewer drive failures, and all the theological arguing that ensues.

I have occasionally toyed around with the idea of psychic powers being caused by hyperspace travel (although not going full 40k with it) to explain why there are people running around with blatantly obvious psychic powers when there was no such people back when humanity was confined to Earth. Potentially also use it to explain why none of the inevitable ancient, hyper-advanced aliens are around anymore- they kept using hyperdrive, so they kept getting more and more psychic until they ascended to a higher plane of existence.

>>54142178
Dark matter's been observed as well as something that only interacts gravitationally can be. It's quite a sure thing (though the details are less so).

Dark energy's definitely still on the "the fuck?" side of physics, though.

>>54141693
no FTL with relativistic effects
Realistic, and for realm building. Each world is completely isolated culturally/technologically from others. Allows for interesting war aspect, as anyone with an "interstellar ship" can hold a planet hostage, and easily kill those fuckers that pissed your great grandfather off. Limited galactic options though, as why would you follow any type of centralized authority. Any reps your planet sends will arrive after you die, why would your grandchildren trust some old fuck who disapeared for a hundred years or so to represent you. Communication as well, taking only slightly faster than you can physically go there (Ender series had a mumbo jumbo solution that worked somewhat). All in all, best setting for books. Potentially games as well. Some ancient civ or some other mcguffen spread over multiple planets. Each very unique, have a water world, desert world(THE SPICE MUST FLOW), world with all cyborgs, world with no tech, world with monarchy, world with mega corps, ect. the possibilities are endless. Literally the best adventure game, and should players die, new people can be recruited creating a diverse party with very different backgrounds(Farscape).

Removing the 3rd dimension.
1. increase range to such an extent you will hardly ever fight over 2 vectors(LOGH).
2. location fiat, battles in areas with very limited navigable space
3. gentlemens agreements(lol)
4. make it only a board game(BFG looking at you kid)
5. humans shake their perception terribly, all aligning up in the same axis when in formation, and then attacking together in such a fashion(Battle Room in Enders Game)
6. dont explain it, just do it, justify it with fun, ease of rules, ect

Its very hard to justify 2d, in the most 3d environment you can have, when you are not making a game. Games only depict it this way as it becomes exponentially more complex to accurately use 3d in anything more than 1 ship, 1st or 3rd person games. Controlling more than 1 ship in a 3d space would give people headaches.

>>54143783
The 3rd dimension really isn't that significant in space combat anyway, on account of the ecliptic plane and the importance of gravity slingshotting for getting around star systems.

Attacking from above or below would take such an enormous expenditure of fuel that it would likely mean the attacking ships would be very poorly armed and armored for their size compared to the defenders around whatever planet or asteroid base was being attacked.

But what if the third observer can't observe? As in, he can't see what's going on inside the wormhole/bridge. To him it just looks like someone disappear, then reappear somewhere else.

>>54145706

I imagine getting hit by a bubble of spacetime moving faster than the speed of light would hurt a lot, even if the ship inside "Wasn't actually moving at all"

While leaving the ecliptic is hard, it's not that difficult to enter an inclined or even retrograde orbit around a planet or moon, you only need to make a very small adjustment to the angle you approach it, and suddenly you'll be coming in at an angle.

Interplanetary space is more or less 2d, but in orbit, threat vectors are a complete hemisphere, with the Horizon being the most dangerous (anything could pop up out of it) and the space "above" you being something to keep an eye on as well.

>>54142178
We aren't wrong about relativistic effects and causality breaking of > c, period. We can be wrong about a lot of things, and have newer models, but the truth of relativistic effects and causality breaking is an universal truth.

You are arguing that gravity doesn't necessarily exist because we haven't the most perfect theory possible for it. This isn't how it works. Yes, we can find ulterior development and affine our understanding of gravity. This doesn't mean that gravity doesn't exist, or that we will suddenly find a theory that say that gravity doesn't exist. Gravity exists kiddo. You are not failing out of the earth because it exists.

We see gravity. We experience gravity. We know gravity exists. Our understanding of the universe makes gravity obvious. Our understanding of it can be flawed, but gravity won't suddenly disappear in a puff of logic because a new theory appears.

Same thing with relativistic effect and the causality breaking effects of speed superior to c. We know, for a fact, that they exist. We can certainly create new theories, affine our models, call it something else, say that it is caused by something else, prove it is only an aftereffect of some quantum gravity theory. But relativistic effects won't suddenly disappear in a puff of logic. They exist.

>violate causality
I fully admit I don't understand quantum mechanics, but still, this idea that outrunning a particle can constitute "violation of causality" sounds like violation of common sense. Same as "if you move in circles around a space string you can go back in time", which even scientists admit is obviously impossible and likely will be proven to be a mistake by future discoveries.

Even if it IS true, it is the kind of scientific thing that should be disregarded first and foremost, when making allowances to accommodate your sci-fi.

You're outrunning the information speed cap of the universe. Light simply happens to travel at that speed because it is the fastest speed that can be traveled.

I don't get why FTL users don't like the consequences. FTL is a perfect plot device, it gives god-like power to the first jackass who gets their hands on it and does a little basic engineering.

It's a setting where humanity has managed to colonize different star systems but they are physically isolated because no FTL.
>Internet is highly advanced, allowing people to practically live in a virtual world and normally interact with people from anywhere, using advanced artificial reality. Imagine Matrix but populated by people from different planets and star systems.
>Planet dwelling humans develop radically different cultures. Some are individualist and live in an extremely advanced society and spend their lives mostly in the web being cared by robots and indulging themselves.
>There is trade going on between star systems (rich people from some places like to buy stuff brought from other star systems simply because they can), but since the ship and crew frequently spends decades travelling from system to system, they have developed their own kinda tribalistic culture (they can't properly connect into the web from a ship that is traveling at fucking fast speeds from one system to another, so they only interact with other people who live on their ship and the numerous androids and AIs that also populate it) which is relatively similar to the long extinct old Earth culture (more exactly: pre galactic-war Earth. Life on Earth doesn't exist anymore btw - we managed to fuck that up beyond repair). They still use relatively ancient technology and are treated as living dinosaurs ( which they are, actually, since your average starfarer have lived for centuries with the help of cryogenic sleep ) whenever they interact with system dwelling folk.
>Of course you could leave the business of sending shit from one star to another to unmanned ships, but that doesn't happen because there are outcast people living in the asteroid belt borders of star systems who frequently attack ships that are coming and going and theres also an old pact forbidding AIs & robots from killing people, meaning starships need humans aboard to defend it from the other bad humans.

It's just how the universe works.

Why do apples fall down? Gravity. Why gravity? It's just how the universe works. There is no reason. Just one of the fundamental rules of the universe. God could have chosen that mass repels mass instead, or that mass has no bearing on other mass. He chose gravity. It's completely arbitrary. There is no reason for it. It's just how everything... well, everything is.

Same thing for the information cap of the universe (or relativity). God could have chosen to give no information cap. There is one. It's just how the universe works. Why? Because it's just how it is.

We know it's how the universe work. We know it really, really, really well. All modern physic is based on it. It has been proven in ten thousand experiments. Why? Well, why not?

You have issues grasping relativity because you don't experience it every day. You experience gravity every day. You have no issues with apple failing down (but why are they failing down? There is literally no reason for it). As you don't understand this very fundamental law of the universe every day, it seems just crazy to you.

>>54153016

It's technically untrue that there's an information speed limit, but the only way to break it (as far as we know) is with quantum entanglement, which opens up a whole new layer of weird shit. Hope you like retroactive suspension of self-interference (or really self-interference generally).

>>54153098
Information is tied to time.

Your information can't travel faster than time, because information is literally the exchange of something in regard to time.

Things that goes quickly constitute their own space time, detached from the universe and everything else. In fact, EVERYTHING that has not your exact speed and your exact place is detached from you, but you synchronize with it at the speed of c.

The speed of c being very, very large, you don't see that when you take a jog. There is a lag between your personal space time and, let's say, the earth space time (light cone) when you take a jog, but this lag is so minuscule you never actually experience it.

When you travel very, very fast, your personal space time get very, very desynchronized with the rest of... well, everything. That's why time slow down.

When you travel faster than c, you travel faster than every possible space time. You desynchronise with the rest of everything. You time travel.

Quantum entanglement can't be used to transmit information. Not without bullshit magic.

The math is very, very clear. You can't transmit information using quantum entanglement.

There is a sort of action at a distance when the wave function collapse, sure, something, but again it can't be used to transmit information. Not without some bullshit science fiction theorem.

Good for a sf setting, though. IIRC EVE uses quantum entanglement (+bullshit magical maths) for his faster than light communication.

It's been observed just as well as the Victorian aether. They knew light was a wave, and waves had to propagate through a medium, and so they knew the aether had to exist.
We know how gravity works and that there is more of it than there should be for the observable universe, so we know that dark matter that only affects gravity exists.

Just because it has to exist to fit within our current knowledge and theories doesn't mean it does or we're correct.

>>54153432
> and waves had to propagate through a medium,

What?

Did no one thought about making a void in a cristal jar and see if light could go through or not?

>>54153349
The EU is such a silly place.

>>54153490
The whole point of the aether was that it was an immaterial medium through which light propagates. It isn't air and you can't expel it from a jar with a vacuum pump.

>>54153490
The thought was such:

Every wave propagate through something.

Light is obviously a wave (sic).

Light propagates through something.

If we can't detect that something, it just means it's something subtle enough, and pervasive enough, and invisible enough, that we can't detect.

Pretty logical conclusions. Honestly, the aether is a logical theory, one thought by the best minds of their centuries.

>>54146023

I think you get it wrong.
Relativistic effects apply when moving. FTL movement breaks causality. No arguing here.
Key word here is MOVEMENT. Something that can have speed.

If you travel through hyperspace, do a null-space jump (i.e. tha kind of hyperspace where distance does not exist and you simply disappear in one place and appear in another) or using a wormhole you do not MOVE faster-than-light. You just stand still or move at regular speed and then just so happen to disappear at one place and appear at another. You do not move fast enough to cause any noticeable relativistic effect.

>>54152910

>Early edition battlestar

My dick.

>>54154390
You are teleporting from space time A to space time B.

No matter if you are physically travelling, if you experience acceleration, or some shit. No matter if you use Alcubierre drives or wormholes. You are instantly teleporting from space time A to space time B.

The information speed cap of the universe is c. If you are teleporting from space time A to space time B, ignoring the information speed cap (and that's exactly what superluminal speed means), you are literally travelling through time.

If you go from A to B, and then go to A again, you will travel in the past. That's a perfectly understood consequence of relativity. It's just how it works.

Using any mean, any way of superluminal travel is travelling through time, by the very definition of what is time, and how the universe synchronizes differing space times together. Sorry. That's just how it is.

>>54154541
Time is a social construct anon

>>54154541
Then it isn't me that arrives at point B. It something absolutely identical. Me at point A just ceases to exist.

Point is, nothing in real universe, not even information, travels in the process. Object disappears at point A, same or identical (the difference is purely academic) appears at point B. It is about as plausible as existence of wormholes or hypespace.

Plus, if we allow existence of hyperspace, and possiblity of matter crossing from it to realspace, the causality simply cannot apply in this case.
Say, we are at point Ar in realspace. We cross over to hyperspace, to point Ah. Then we travel through hyperspace to point Bh, which takes us an hour. Point Bh corresponds to point Br in realspace. Will causality somehow stop our spaceship cold in the wormhole between Bh and Br?


Point is. Everything about relativistics and causality revolves around bog-simple MOVEMENT. Them moment we take actual MOVEMENT out of equation the problem disappears. Relativistic laws have no exception for that because hyperspace or wormholes simply don't exist.

Note that I don't argue that any other forms of FTL - Alcubierre drives, space snarling, intertia absroption, etc - still violate causality.

>>54154541
>you will travel in the past.
Say it takes me 5 minutes to travel to the Sun.
I'm going faster than light, but it still took time.
If I go back to earth, I'm not going backwards in time.
It still took 10 minutes.
I won't experience 10 minutes, that's a given, but I'm still not going backwards in time

>>54153283

>>54154703
your personal time will go back in time.
If you travel a lightyear at 0.99c, you'll experience, say, a minute.
If you travel a lightyear at 1c, you will feel that you arrived from A to B instantaneously.
If you travel a lightyear at 1.01c, you won't remember yourself pressing the START button.

>>54154703
You are assuming that every space time of the universe are the same. You are assuming that the space time (the real term is light cone, but whatever) of the sun is the same space time of the earth.

That is not true.

The sun has its own space time. The earth has his its space time. They aren't moving in the same direction, at the same time, at the same place. They both have their personal time, and they both synchronize their personal time through the information speed cap c.

There is no divine, objective time. The sun has its space time. The earth has its own space time.

If you teleport from the earth space time to the sun space time, you are being faster than the synchronizing speed of them both. You are time travelling. If you teleport back to earth, you will go back before you started your journey.

Again, that's just how the universe works anon. It's incredible, it's mind-blowing, but the maths of special relativity can be understood by 13 years old. It's just than nobody thought of breaking universal time before Einstein.

>>54154692
Instead of visualizing points being in a absolute time, visualize points synchronizing their own time through the information speed cap.

There is no sea of absolute time. It is 8 PM here on earth, but on the sun? That question is incredibly complex. The sun share its space time with us through the information speed cap c.

If you want to go faster than c, you will time travel. It's 8 PM on earth. You teleport. It's 8 PM on the sun. Fun fact: 8 PM on earth and 8 PM on the sun DON'T mean the same thing. 8 PM on the sun really mean 7:53 PM on earth. The space times aren't synchronized yet. You teleported faster than c, remember?

If you teleport back to earth, congratulation, it's 7:46 PM. You arrived before you started.

>>54145733
This is why the observer paradox is nonsense. Unless entering/exiting FTL creates light shows the size of Olympus Mons, the light just isn't going to be detectable over interplanetary scales unless you know exactly when and where to look with some very large telescopes. At interstellar range it would have to be planet sized flashes of energy. People getting so hyped up over this stuff don't take the experimental astronomy side of things into account. The only real FTL time travel shenanigans possible is Picard Maneuver microjumps to gang up on an enemy.

The only thing we're missing for FTL comms is persistent entanglement that lasts over an arbitrary number of measurements. I've yet to see the math that proves persistent entanglement is impossible.

That's not a fair analogy. The aether didn't have any supporting evidence; it was always supposition and generalization from analogous systems. We do have actual observations of gravity effects without anything in the EM that would be seen from conventional substances. Maybe that's because there's an extra six terms in the theory of universal gravitation that we've been ignoring, but it doesn't really matter: evidence for the phenomenon actually exists, unlike for the aether.

>>54157513
Evidence did exist at the time. They knew that light was passing through space. They knew light was a wave. They knew waves needed to propagate through a medium. Ergo they theorized some mysterious substance they couldn't see or interact with to fit their theory for light to travel through.
We know galaxies have more gravity than they should. We know that mass seems to create gravity. So we theorized a mysterious substance that we cannot see or interact with to fit our theory and to create the gravity.

Their evidence was light being a wave and yet passing through vacuum, hence aether.
Our evidence is gravity being where there is no visible mass to support it, hence dark matter.
Both were/are great theories for the evidence present at the time, and I'm not a scientist, but I'd bet good money dark matter will go the way of the aether. Probably some bias from being an engineer who prefers science with data instead of predictions.

>>54144088
This is so stupid

Why and how does the big ship slice through the other big ship if the little ship is the one supplying all the energy? Why doesn't the little ship slice through the big ship then?

I could've believed it if they connected with about the same force as the little ship supplied, but they basically turned the big ships into soggy paper mache

dumb as fuck

>>54155340
Entanglement NOW can't transmit information, because the entanglement breaks after taking measurements of the entangled objects, but persistent entanglement that doesn't disappear after a measurement is taken COULD. Take persistent entanglement as a given and the rest is basically down to protocol design and hardware engineering problems. I suspect the L2 protocol will end up being Ethernet with jumbo frames for backwards compatibility reasons.

>>54156465
The basic gist of it is that causality itself propagates at the speed of light - reality has a draw distance. FTL makes physics weenies with no imagination sperg out because it implies that shit can happen (and most likely HAS happened) in violation of causality. This in turn calls much of what we think we know about history, prehistory, and cosmology into question.

>>54153666
light travels through spacetime

So they're right, the aether exists, it's not nothing, it's spacetime itself

>>54159649
Not to mention that "vacuum" is actually full of particle-antiparticle pairs constantly appearing and annihilating. One hypothesis on the emdrive is that it pushes against these particles to create thrust. If that's true, we might as well say "aether" instead of "quantum virtual particle pair foam" since it's shorter.

>>54159533
It looks to be a structural hardpoint where the hammer ship hits. They look like they trained specifically for this. If you look at the first star destroyer crashes into broadside (obviosly imparting a great deal of energy and thus damage to a wide section) and lifts up a horizontal section, something that's probably far easier to do due to how it's constructed than slicing vertically through the ship.

Like grains in wood, it's easier to cut one way than the other.

That was ultimately the conclusion after much testing; that either the aether did not exist and there was clearly something more to light (there was and current theories do indeed deal with this "something more") OR that the aether did in fact exist but had absolutely no properties other than existing and could not be interacted with in any way what so ever leading to it existing in a state such that it might as well not exist.

Okay so i wan't to give my players a cyborg ship, but i also don't want to bullshit and handwave my way through.

So i got a few questions and the hope to get some answers.

So, a living ship could probably store fuel in the form of good old water and some fuel processors (mechanical or organic) for it's gravitation engine and on board hydrogen fusion power plant. But the FTL drive still needs his hydrogen to create his extradimensional pocket.
> How does one store hydrogen in a living ship for the FTL drive ?

Since the whole thing is an amalgation of mechanical and biological parts.

Fat tissue is hydrogenated lipids. The ship stores fuel by eating.
>living systems
The ship should have plant-like systems for exchanging CO2 for oxygen, and for water filtration and routing. Make it warm-blooded and it handles climate control entirely through living systems that self repair and can't be EMP'd. Grappling arms should be Space Tentacles as well for maximum control and flexibility. If you're still short on ideas, watch Farscape.
>how does a living ship handle combat
Not well. It'll either run away when given half a chance (again, watch Farscape), or try to kill and eat the other ships. Neither option works well for space pirates interested in salvage or boarding action. C&C systems are best left purely electronic/mechanical/biomechanical without the ship having much of a brain.

Generally I think the (pseudo?)organic part is best left for building the ship and making it its own dock for repair and modifications. You get your fancy coral look and the ship doesn't die from radiation and combat damage.

The actual living ship is IMO a bad idea (but it can be cool in its own context especially if living ships can do something special like fly by telekinesis or whatever) but you could consider the crew to be living parts.

When you said cyborg ship I first thought you meant a ship crewed by cyborgs which IIRC is doable at high TLs in Traveller.

>> How does one store hydrogen in a living ship for the FTL drive ?

What? Living systems exchange hydrogen constantly in the form of protons. Your molecules are mainly made of hydrogen attached to carbon, just look at any lipid formula or even water and realize that hydrogen is everywhere in biochemical systems, you can get moles and moles of hydrogen for free, and even if we talk about isotopes I wouldn't think you should find that many differences for tritium or deuterium
>>Which systems can be taken over by the living systems of the ship ?

As many as you want to handwave or investigate. You can even make lasers out of proteins, control systems are not really that limited by neurons just make sure to make them big and hot to accelerate reactions to levels of electricity, circulation is also easy and works on all levels, and contrary to popular demand living systems can extract energy from redox reactions out of fissible materials like uranium and resist up to 10.000 grays of radiations so living systems can make the powerplant too, and the propellant can be hydrazine(that can be produced by bacteria out of ammonia) or simple water, living systems are expert chemists into mass producing molecules so go wild if you wish.

>What does the fact, that the ship is alive (albeit as smart as a bug/fish) change in space combat ?

Again, as much as you want to handwave or investigate.

Living systems are different from normal ones in the sense that can exist on all levels of existence; that is a robot can't repair a tiny transistor in his CPU without help but a biological system can reconvert a cell into a neuron or simply eat the broken cell and stimulate others into substituting it, that means that most of the damage in battle can be self manageable if you have the matter and energy, but this one you already thought.

But try to think about living things more along the lines of nanomachines based around carbon and then realize about the posibilities.

Ether diving: Dive into a lower dimension where you have to spend MORE time traveling than if you stayed in "reality". When you "surface" an observer in real space would see it as you spent less time traveling a set distance than would otherwise be normal. The deeper you dive the stronger the inverse relationship is.

Example: Heading to a start 10 lightyears ( ly ) away. Accelerate to 0.25 speed of light ( c ). Normally trip would take 40years in real space.

Instead, accelerate to 0.25c and "dive" to a "depth" of 5. The ship must spend 200 years (subjective) in the ether. Once it "surfaces" the relative time the trip would take is 8years.

Dive deep enough an the trip would be near instant relatively, just better build that ship good and have awesome stasis. Can also use it for neat parlor tricks like: turning your week of vacation time into month/year/decade long luxury cruise; waiting out icky radioactive decay; jailing hyper criminals; repairing combat damage and returning to the fight, while its still going one; etc.

One I'm playing around with four a setting:
The universe has at least four spatial dimensions, and by moving through the fourth dimension, distances that seem vast can be covered in relatively little time. Your ship needs something that can calculate your 4D route and bring you through it: most ships use a really advanced AI or computer to calculate the route, and some sort of incredibly powerful generator to produce the energy needed to let the ship navigate those four dimensions. Some ships have 4D drives that are actually advanced cages for lobotomised, 4D shoggoth-like creatures: being 4D themselves they have no trouble navigating 4D space, so they're given coordinates and set off, dragging the ship with them.

Then use the TL to stablish as many limits you want. Althought a cybernetic ship is something pretty advance I can mostly describe the biological parts.

For example, lets stablish limitations:

>Biological systems do not take easily high levels of energy in short times, that means that you can't use high powerfull lasers or railguns and you are only limited to missiles and drones. But in limitations you can specialize, taking advantage of being able to grow your ammo and according to the needs you want; from biological nukes(Casaba-Howitzers not excluded), armor devouring bacteria/fungus or simple high mass/density slugs capable of self propelling and steering themselves with precision. The limit is what materials do you have available and how much energy can you send into the synthesis of more biological missiles

Of course, they can be taken down on their way there, but you can choose to armor them or make more of them, according to the situation they can be adapted in minutes.

>Your ship basically cannot land on plannets with atmosphere, the only way to do so is with lithobraking which just mean a controlled crash and a big shield to absorb the impact and breaking, so you would need to grow another plus the extra fuel+propellant to reach orbit again which is surely a time consuming task.

>Your ship has problems with communications and computer systems, that means that while you don't need a fuel depot and are invulnerable to hacking you cannot interface with other ships in any way, you cannot receive images or complex data and any task that requires coordination with electronics(pretty much everything in space) is impossible unless you design and create the required biochemical-electronic interface which of course is not easy to make.

I could go on or even explain ways to biologically overcome this, but this is just to say that you can establish limits too.

Time and space are very related is what people have been getting at I think. If you travel through space, you have traveled through time, if you travel through time you have traveled through space.

>>54185225
Temperature can be defined as change in energy over change in entropy, although it's usually more useful to define change in entropy as change in energy over temperature or ds = dQ/T. Entropy can roughly be thought of as the spread of the energy levels within the material.

For most forms of matter, entropy will always increase when you add energy, because there are an infinite number of energy levels that the particles can occupy and so the spread always has room to increase.

In some forms of matter there are only a finite number of energy levels, which means that entropy reaches a maximum when the average energy is halfway between the maximum and minimum levels. Adding more energy to the system will push more of the particles up towards the maximum level and actually reduce the spread. Basically what this means is that heat starts flowing in the opposite direction until the energy falls back below the threshold.

>>54142021
>>54142056

Wormholes don't allow for FTL movement, friends.

If point A and point B are 5 light years apart by conventional understanding but a wormhole connects them the distance between them is the distance though the wormhole, not the conventionally understood distance. Despite traveling what looks like 5 light years in moments you are never, at any point, FTL.

>>54186475
FTL is forbidden by causality anyway. But don't try arguing that here. People don't have much other than their beliefs here.

>>54186463
Yes but due to it being the lowest possible energy that cannot be removed, it cannot be removed. So no ZPM's ever.

Energy can be removed from a negative temperature system, it just causes the temperature to become less negative until it flips back to being positive. There's really nothing magic about it.

>>54184847
I don't get it, it's from a game? A serie? Books? Any help?

>>54186944
Negative temperature systems don't exist in reality. It's simulations and maths they're talking about.

Think about it. There's no such thing as negative atomic motion.

>>54187124
there's an old russian joke

Now, if estonians were actually standing, not running, that'd be negative motion.

>>54187124
If negative temperatures ever got observed IRL it would be a strong suggestion that our reality is a simulation with buffer overflows.

>>54187312
>a strong suggestion that our reality is a simulation
that would be proof, not just suggestion
there's plenty of suggestions that we live in a virtual simulation IRL.

>>54187312
There is no evidence which would suggest we live in a simulation because we have no control universe to compare it with.

If you'd thought about it, you might have realized that entropy isn't the same thing as atomic motion.

random events in the world normally unfold in the way you'd make them unfold to conserve processing power

i.e. things repeat themselves for no apparent reason, like cars of exactly same colour and/or model in same place on same day or even hour

same music - and not just something popular today - playing in various places on same day

plus one really creepy incident I had. I was walking a street that intersects with main street of my city. yet for some reason there was no one on the main street. then a person passed. then a few persons. as I approached, the density of movement on the street increased, and as I entered the street, it looked normal - and there was no sign that there ever was a gap in that movement. it felt exactly like video game engine only rendering certain things as you approach them. likely there was nobody but NPCs on the main street that hour.

plus you can't really meet people without realizing that at least some of them are nothing more than one-dimensional NPCs that just probably just stand there staring at the wall with glassy eyes when no real person sees them

Well fuck.

>>54187380
Welcome to the early twenty-first century, human.
It’s night in Milton Keynes, sunrise in Hong Kong. Moore’s Law rolls inexorably on, dragging humanity toward the uncertain future. The planets of the solar system have a combined mass of approximately 2 x 1027 kilograms. Around the world, laboring women produce forty-five thousand babies a day, representing 1023 MIPS of processing power. Also around the world, fab lines casually churn out thirty million microprocessors a day, representing 1023 MIPS. In another ten months, most of the MIPS being added to the solar system will be machine-hosted for the first time. About ten years after that, the solar system’s installed processing power will nudge the critical 1 MIPS per gram threshold—one million instructions per second per gram of matter. After that, singularity—a vanishing point beyond which extrapolating progress becomes meaningless. The time remaining before the intelligence spike is down to single-digit years.

Intelligence simulates. One could say that intelligence is simulation, minds pathing through phase space, matching vectors, squaring the probabilities of the world away. Greater minds simulate greater things. One day, sooner than you think, an intelligence will simulate an entire universe, cruder than our own. And the cycle continues, universe nested within universe, turtles all the way down...

It's not physics. It's mathematics. It's probability. We are a simulation. The odds are an asymptote, arbitrarily far past the inflection point. One. It's not "if", it's "is". Anything else is blind, childlike, self-importance.

>>54185478
IIRC, you can, but it would require creating a contained quantum vacuum collapse, which would create a Universe destroying explosion if the containment failed.

>>54187968

If you go faster than light, then you aren't going be the same as everything else in the universe that can't.

Nope, a lot of people are incredibly dumb and lazy, even for people with functioning empathy. He's still wrong, but not for the reason you claim. Getting through life to reproduce and raise your offspring with a minimum of physical and mental effort is explainable as the parallelized optimization of evolution at work without any need for an extra-universal force, whether you call that God or the simulation-runners.

>>54188502
That's novas, not supernovas. The nova is the universe telling the star to cut it out.

15% of the population, on average. The rest are above that. Bell curve, remember? They just seem dumb because you're not a people person.

>>54188599
no, that's supernova. the pressure grows too strong and tears the outer star into atoms, while the inner part collapses into black hole or neutron star.

i don't remember the mechanism behind nova, and i'm too lazy to google right now (iirc it happens in dual star systems when one star is pulling matter from another, but i may be wrong). what I AM sure of, is that it doesn't destroy the star, is less bright than supernova, and is kinda periodic.
