Any space faring civilization or tech advanced species, is looking for something. If you're looking for something out there, you're not looking for friends. If you're not a friend, you're a competition and an enemy. But that doesn't mean there are no friend seeking species out there.

(23:2.22) 6. Ambassadors and Emissaries of Special Assignment. Local universes situated within the same superuniverse customarily exchange ambassadors selected from their native orders of sonship. But to avoid delay, Solitary Messengers are frequently asked to go as ambassadors from one local creation to another, to represent and interpret one realm to another. For example: When a newly inhabited realm is discovered, it may prove to be so remote in space that a long time will pass before an enseraphimed ambassador can reach this far-distant universe. An enseraphimed being cannot possibly exceed the velocity of 558,840 Urantia miles in one second of your time. Massive stars, crosscurrents, and detours, as well as attraction tangents, will all tend to retard such speed so that on a long journey the velocity will average about 550,000 miles per second.

The Alcubierre drive (purely theoretical, many problems with it that would need to be solved first) could hypothetically result in FTL travel, but also violates causality.

Regardless, even without FTL, interstellar travel isn't necessarily impossible, provided you can accelerate to relativistic speeds, or have some form of cryogenics, or something similar.

They say the distances are simply to gigantic to be bridged and the galaxies move away faster than the speed of light so physics says it will NEVER be possible to travel to another galaxy.
None of that is true. I did my dissertation on extragalactic motion. It would take me so long to explain it and youd understand so little of it I wont bother. But basically if galaxies are moving away faster than the speed of light (relatively) then light would never reach us and we'd never see them, so dont worry about them getting away.

>our bodies would have to adjust to the immense pull it'd generate
You mean the force you experance during acceleration? You can accelerate slowly and not pull any Gs, acceleration is only the rate of change of speed, it has nothing to do with the actual speed.

>what if in the course you strike some asteroids and wreck your shit to shreds
Statistically impossible. You dont understand how big space is, and interplanetary space, setting aside intergalactic space, is so much bigger than you think it is.

I know its /x/ and all, but theres really no excuse for being this bad at science.

>>18922873
There is always wormhole drives, but you would need huge energy generators. But if you could convert Jupiter's mass into usable, controlled energy, you could go anywhere you wanted instantly.

>>18923056
>interstellar travel isn't necessarily impossible
I think there's no doubt that interstellar travel will be possible within the next century or so. Intergalactic travel, however, is likey impossible unless we have some major breakthroughs in quantum physics or some similar science. A breakthrough which would undoubtedly usher in a new age of man

Even Star Trek takes place entirely within the Milky Way galaxy. The Borg are just from the most remote quarter of it. It's pretty optimistic to have no doubt that there will be interstellar travel within a century. I wish I could be so optimistic despite my hatred for environmentalism but that's another thread.

Intergalactic distances are mindbending and I do agree we would probably need to get beyond thinking about things like "speed" and "distance". We would be needing to get into the transhuman sphere at that point, I think.

Once humanity migrates to energy things will change and it might happen sooner than you think. So many people on 4chan can't wait to have AI/VR waifus. That's a huge step. Once people fall in love with artificial intelligences and have children with them that'll be the true beginning of the end for meat.

You think intergalactic distances are wild? Think about pure mathematics. Do you have any idea how big a number a googolplex is?

>>18922873
It'll be possible someday. It's only a matter of time before our solar system collides with another.

>>18925275
Gonna be a fag now, the Borg are actually a galaxy spanning collective that make use of mass wormhole relay stations located near the center of each galaxy. They then spread from the wormhold relay system until they overtake the entire galaxy.

So to move between galaxies, wormholes, to move in the galaxy, star trek warp.

>>18925294
Yes, a matter of approximately 10,000,000,000,000,000,000,000,000,000 years

>>18925320
That's interesting. Do they show their interaction with other galaxies and the life forms there? I would have assumed Star Trek would break away from their "mostly-humanoid" canon for other galaxies. I always thought fluidic space was interesting.

>>18925328
they don't really do much with it other than "terrifying reveal, you know how borg are bad and there are a lot of them? well bad news because there are really a SUPER FUCKTON LOT OF THEM!", I think the one for our galaxy got blown up a few episodes later and the borg can't build another quickly so it slows them down in our galaxy.

>>18925320
I'm interested in where you get this from. The wiki makes no mention of any of this, and this stack exchange I found specifically denies the Borg are intergalactic.

Gonna go the spiritual route here. When I astral travel in dreams, sometimes I am able to enter into a starfield of energy. Then I move somewhere else and drop out of hyperspace, the environment stars to look 3d again and its like I have moved to a different energy in creation and can see differences in the dream world. Basically the world in the astral is built out of astrological energies of our galaxy. I saw a bunch of insects last night, like centipedes and a mantid being. I heard from my guide when I woke up that I had moved to some constellation they called paleous.

Once, I traveled to the edge of our galaxy and I saw what looked like dark matter bridges going to other galaxies. Also higher dimensional intelligences were able to unwrap parts of our galaxy like pulling a thread out and make modifications to it. It seems that the galactic structure is related in some quantum ways to the chemistry and molecular biology of the life that lives here.

A few times, I have been able to project myself into the mental plane. When I did this I can sort of turn the spiral of energy in my crown chakra and synchronize it with different space time configurations. I did this with et help from the arcturians a few times, and they have modified my astral body so I can sometimes do it myself. So I was able to turn the spiral in my head and align to a different central galactic black hole I ended up teleporting information from Andromeda and it was like I was in deep space inside of another galaxy.

One other time, O tuned my crown chakra with some really weird vibrations I was picking up in the astral, like a high pitched sound. I modulated it until it was too strange to comprehend. Then a strange et being showed up and told me that I was accessing energies from further into the galactic supercluster. Basically, people on dmt who are able to exit our local universe may be doing the same thing, but it is also possible to do so through astral travel

>galaxies move away faster than the speed of light
Only very distant ones. And the galaxies aren't exactly moving away, the space they're in is expanding away.

>>18925864
The galaxies aren't moving faster than light. The most distant ones are so far away that the light they produce simply hasn't reached us yet and are therefore invisible.

Space can move faster than light though. Since light is in the universe and cannot exist outside it then the universe is expanding faster than light. However space does not expand evenly. It moves faster at the terminus and slower everywhere else.

>>18925595
Carbon rings form in a vacuum. Life elsewhere isn't just possible, it's likely. Us making contact with it however is another issue.

>>18925530
Some of them do. Dark Energy fuels spatial expansion, and the further out you go, the greater the rate of that expansion. The relativistic speed limit does not apply to the space between things, which is free to grow as quickly as Dark Energy can fuel it and there doesn't appear to be any upper bound.

If we can move 50,000x or more faster than light.

It takes two million years and some change for information to reach us from Andromeda. Andromeda is the older galaxy, maybe the Andromedans will reach us first? Given our proximity to the edge of the Milky Way we might even be one of the first stops.

>>18926607
Space is expanding evenly. The farther apart two things are, the faster they're moving away from each other. Beyond a certain distance, galaxies are moving away faster than light. It's not just that the light hasn't had time to reach us; it can never reach us.

Imagine a meter stick made of stretchy rubber. Over the course of 1 second, stretch it so it's 2 meters long. Any two points that were 1 cm apart are now 2 cm apart, so they moved apart at 1 cm/s. Points that were 10 cm apart moved apart at 10 cm/s. Etc. Now imagine the meter stick goes on forever, like the universe. If two points are far enough apart, they'll be moving apart faster than the speed of light.

The sphere inside which things are moving away at LESS than the speed of light is called the Observable Universe. Light from outside this sphere will never reach us, even after infinite time.

>>18924357
>no excuse for being this bad at science.

Says the guy who doesn't know the difference between impossible and improbable.

It already is possible.

>>18927776
Well put. The scary part is that the Observable Universe is shrinking.

https://briankoberlein.com/2016/04/29/incredible-shrinking-universe/
>Since the observable universe is about 42 billion light years in radius, and the Hubble radius is about 15 billion light years, that means about 97% of the observable universe is beyond our reach. Furthermore, since space continues to expand, galaxies that are currently within reach will eventually move beyond the Hubble radius. Our galaxy is part of a cluster of galaxies known as the local group. It is about 10 million light years across and contains about 50 galaxies. Together they are close enough that their gravity will cause them to collapse toward each other despite cosmic expansion. But more distant clusters are so far away that cosmic expansion will win in the end. In perhaps a hundred billion years our local group will have collapsed into a single large galaxy, and the rest of the Universe will have moved forever out of reach.

>>18928339
From another frame of reference, yes.

Nothing in the galaxy has been found to move faster than the speed of light. Our galaxy, any other galaxy - this seems to be an absolute limit on how fast through space you can move. SPACE, on the other hand, is expanding. And the more space there is between two objects, the more the expansion of space will "add" to their movement. Look at pic related: none of the dots move at all, yet clearly the distance between the dots has increased. What happened? The space they occupy - the coordinate grid - has expanded. And the dots that have zero speed have moved further apart.

This expansion of space can make the rate of increase in the distance between two objects be faster than the speed of light, even though neither object can actually move that fast.

Maybe not with conventional travel, that's why our biggest task is now figure out how to stabilize a wormhole.

So no, it's not sad since space time manipulation has already been proven. If the universe itself is capable of bending time, so can we (with a couple x thousand/million/billion years of technological advancements).

>>18928444

I don't have a soul.

>>18928394
Before we go further, I'd like to point out that the expansion of space is really quite miniscule. From the website I linked:
>We measure cosmic expansion in terms of the Hubble parameter, which is about 20 km/s per million light years. This means that two points in space a million light years apart are moving away from each other at 20 kilometers each second.

Let's get that number down to comprehensible units of distance. If we apply that rate to just one light year, then every second the space therein expands a whopping 20mm.

Now 1 light year equals about 63,241 astronomical units, which is the distance from the Earth to the Sun. So that means every second, the space between our Earth and our Sun expands .0003 mm.

Cosmic expansion is tiny, but cumulative; it will only ever be influential for extreme distances.

>>18928410
There have been a lot of very smart people who were adamantly against the idea - Einstein included - who tried and failed to explain away these observations and conclusions. But perhaps you have the answer. You should write to your local observatory or university.

>>18928486

>who tried and failed to explain away these observations and conclusions

They're based on a concept that can't be debunked because galactic motion is an unmeasureable idea.

Motion is measured by comparison. We have nothing to compare the fabric of space to.

In 1976 I was invited to stay overnight at the Jet Propulsion Laboratory in Pasadena, waiting for news to come back from the Viking 1 lander, which was going to touch down on Mars and take photographs.

It was incredibly exciting to be there, surrounded by engineers, waiting for the first pictures. There was a tall gentleman standing next to me, who I thought looked familiar. At last I realized it was none other than Wernher von Braun, the man who had fled Germany for America to become the co-inventor of the rocket that took us to the moon and that was now taking us to the planets.

Early in the morning the photographs began to arrive. I could hardly believe I was seeing the surface of Mars! At 9:00 a.m., ABC television put me on the air to get my reaction.

The interviewer said, "Mr. Bradbury, how do you feel about this landing? Where are the Martian cities and where are all the living beings?"

"Don't be a fool," I said. "WE are the Martians! We're going to be here for the next million years. At long last, WE ARE MARTIANS!"

That was the end of the interview.

(23:3.3) Solitary Messengers are, therefore, generally used for dispatch and service in those situations where personality is essential to the achievement of the assignment, and where it is desired to avoid the loss of time which would be occasioned by the sending of any other readily available type of personal messenger. They are the only definitely personalized beings who can synchronize with the combined universal currents of the grand universe. Their velocity in traversing space is variable, depending on a great variety of interfering influences, but the record shows that on the journey to fulfill this mission my associate messenger proceeded at the rate of 841,621,642,000 of your miles per second of your time.

(39:3.9) These transit personalities are so organized that they can simultaneously utilize all three of the universally distributed lines of energy, each having a clear space velocity of 186,280 miles per second. These transporters are thus able to superimpose velocity of energy upon velocity of power until they attain an average speed on their long journeys varying anywhere from 555,000 to almost 559,000 of your miles per second of your time. The velocity is affected by the mass and proximity of neighboring matter and by the strength and direction of the near-by main circuits of universe power. There are numerous types of beings, similar to the seraphim, who are able to traverse space, and who also are able to transport other beings who have been properly prepared.

Science is the new religion, Anon. Are you unaware? People blindly follow its top prophets (Nye, Tyson) with little to no understanding of the method. Environmentalism is one of the vanguard oppressive dogmas of this religion, standing firmly in the way of human progress. It merely prolongs the inevitable. The fact of the matter is that humanity is outgrowing this planet and if we don't expand off of it in the next few centuries then the population will have to be actively reduced either through war or through breeding controls.
