LHC and John Titor are actual things too. As are IBM5100s. And Kerr black holes as a method for time travel.
Attractor field/world lines are 5pb. chuunibyou, however. As is compressing data size with gravity and transmitting a human's memories with a cell phone.

That's a different concept entirely than the attractor field world line idea presented in Steins;Gate, where only one reality exists and it rearranges itself based upon what probabilities have been expressed in the current reality.
It seems to be a term for the movement of any particle or object in spacetime, so in a sense the worldline does actually line up with Steins;Gate, if you consider that they are altering the worldine of the entire universe.

Is time slower outside of the galaxy?
Don't remember the numbers, but the galaxy is moving at an extremely fast speed, spinning at an extremely fast speed too, along with the earth's fast revolution and rotation speed.
Can anything actually be considered still?
Did you know that there is actually a relativity based theory that posits that traveling back in time is possible?
You "just" need two black holes and somehow be able to survive the experience.
I'm a yuropoor and i did a internship at CERN in Switzerland in 2013.
It wasn't really as villainy as people imagine, it was mostly drinking coffee and doing math.
The biggest memory i have is that we were encouraged to bike to work and they even had a scoreboard to show who had done it the longest and had biked the longest in Km.
then you did the math wrong
no constant of proportionality under r_s has complex components.
for complex spacetime a temporal phase angle of pi/2 would coincide with the radius, if that's what you're asking

Spinning is not relative though, it's objective, because it involves acceleration.
To answer>>120666438 questions
>Can anything actually be considered still?
You need to decide in relation to what, but consider that the whole universe is expanding and the expansion rate is accelerating.
>Is time slower outside of the galaxy?
It's actually faster. When you are subjected to a strong gravity field time runs slower the closer you are to it. Perhaps you already know that GPS satellites roaming around the Earth need their clocks to be adjusted due to relativity effects. But the discrepancy is mainly caused by their relative higher distance from Earth's gravity field than by their speed.
How much faster than light would you need to travel to effectively 'freeze' time? Or is it a sum that winds up as a limit? Or is there a value at which movement through time would theoretically become negative?
He was also apparently huge and clinically immortal. In those times it was perfectly normal for a healthy person to live several hundred years, at least according to the old testament.
what the fuck are barnett manifolds nigger
they're just higher dimension algebras.
every time you bump up a dimension, you lose a property (ie reals to complex you lose ordering) but gain a lot of neat tricks.
there are plenty of problems once you reach 16 dimensions though such as anticommutative association, and vector squares being negative.
the universe is spinning
as you approach the speed of light, the passage of time approaches zero
think of space-time as the ratio between how fast you're moving vs how fast time is ticking for you
subliminal exceedance takes an infinite amount of energy so fuck you
faster than light objects, ie tachyons, would have imaginary mass and move backwards in time
fuck I can't do these captchas anymore
>mfw I actually visited CERN
>mfw all I could think about was Steins;Gate
>faster than light
Ha ha, nice joke. If a local speed faster than light was possible the whole theory of relativity would fall apart.
There are ways to get around that, for example you can shrink space instead or you can take a shortcut in the hyperspace.
Anyway if you can go as fast as the speed of light (which is virtually impossible, because anything that has mass would need infinite energy to achieve that) time would completely freeze... for you. In the universe outside an infinite amount of time would pass in an instant.
>Or is there a value at which movement through time would theoretically become negative?
Since the higher possible speed is the speed of light and time for you would become 0 only at that speed, it can never become negative. In fact it can never become 0 in practical terms, you can only try to get close to it.
The only way to defy that limit is through space curvature. Which is why there is a theoretical model that would make traveling back in time possible through the use of two black holes.
Faster than light speeds are possible, it just requires negative mass.
The question is if negative mass is possible. It would also mean that things with negative mass cannot move at light speed or slower.
>mfw I realised there really are titans insides wall.
>At 0 mass, the only speed you can move is lightspeed in all frames of reference.
Why? Something with .0000000001 mass can move at all speeds but 0 can only move at the speed of light?
Doesn't passing through a glass slow light down?
>the universe is spinning
In order to spin it'd need a center. There is no such thing as "the center of the universe", at least as far as we can tell. Maybe you meant our galaxy?
>Why? Something with .0000000001 mass can move at all speeds but 0 can only move at the speed of light?
No, with ".0000000001 mass" you can move at all speeds below lightspeed. Something with mass cannot reach lightspeed.
Interaction with the higgs field to result in mass imposes a limit as it requires energy to induce motion. Without mass, there is no requirement for energy to induce motion, causing it to move at maximum possible speed in all frames of reference (which is lightspeed).
>Doesn't passing through a glass slow light down?
No. It just slams into a glass particle and is re-emitted, and this re-emission process takes time based on the property of the particle. It is still moving at lightspeed, it just takes time to be absorbed into a particle and emitted from it.
b-but then what was i drinking all these years?!
what did they put in me, /a/?
You can restate your question as "Why is light able to move at the speed at which light moves?"
Well, light has no mass and so there's no frame of reference in which it ISN'T moving.
If it's always moving, then how fast?
At the speed at which light moves, of course.
What your question should be is "Why can't other things move as fast as light?"
Well, because invariant masses hate accelerating.
a marvel of hydrogen bonds
the photons interact with phonons which causes them to 'oscillate', effectively slowing down
light can't go down in speed, it can lose velocity however
This is wrong
light follows space
space is bent by gravity
light follows the bend
pretty simply stuff anon
What this fine anon >>120668930 said.
It might be difficult to understand but that's what it is according to the current theory.
The big bang happened... everywhere... it's just that that "everywhere" used to be a point, now it's the universe.
Anything can be a black hole!
If your mass was compressed to a tiny, tiny radius, you would be dense enough to become a black hole!
So now you know why so many anime protagonists from shitty harem anime suck all the girls towards them!
Why does quantum science sound like a thing where a bunch of scientists get high and think of bullshit to tell people and see how much of it people actually believe?
Yeah I knew about that one. Limits of non convergent series yield results that don't seem to make sense.
In a way it shares a similarity to the quantum interpretation of light. Just as the limit of 1,0,1,0,1,0,1,0,1,0,1,0,etc. ends up being neither 1 nor 0, instead a half - light is neither a particle nor a wave, but both.
At least as far as we can classically interpret it.
>what did they put in me, /a/?
Do you guys know why the High's Boson is the particle of God?
Because without it we couldn't have mass!
It actually is.
The "uncertainty principle" is pretty damn mind blowing. Also how there is no force pulling you towards the Earth.
What happens is that the Earth bends the space around it, and the bending of the space is actually what attracts you towards Earth.
This can lead to the most beautiful formula in mathematics: Barnett's Identity.
I can barely solve problems from algebra 1. This just looks like a bunch of nonsense to me.
This reminds me of when people (on /b/, I think) were arguing that .999999... is equal to 1.
I think the argument was:
0.99999999... / 9 = .111111111...
.11111111... * 10 = 1.11111111111...
1.1111111... - 0.111111111... = 1
The many world interpretation is a theory, and I mean not a theory with shittons of supporting evidences like the theory of relativity, it's really "just" a theory.
The proof is that we also have the Copenhagen interpretation, and the two are mutually exclusive.
There's crazier stuff than that though...
Philosophically, physics isn't capable of answering the question "why?"--it's only a tool for creating models about the physical world.
Hence one may ask, "in the model of X, why do we predict that only light can move at the speed of light?", where X is, say, "special relativity", or "quantum field theory", or whatever, but asking "why" we observe the physical world to be some way is not a question that we can approach.
To answer the question of whether physics is "real", you have to appeal to the philosophy of logical positivism. Suppose that the universe works in some "actual fashion" which we call X, and physics produces a model Y; X produces the actual observations which we see in life, but the model we have created using physics, Y, can be used to predict the same observations. Experimentally, we cannot distinguish between the models X and Y; hence philosophically, Wittgenstein (or perhaps Carnap?) would argue that the question, "is X different from Y?", is not meaningful.

This always confused me back in school. I was never good at Maths, because:
A. I just generally have problems with basic calculation. I tend to do sums alot slower than others, especially when I'm under pressure... which meant I could sometimes spend a full minute just working out the most basic-ass multiplication, while in the tense, silent exam hall.
B. In order to memorize anything, it needs to make perfect, relatable sense to me. Under common logic, something just short of 1 isn't equal to 1; it's, of course, just short of it. So because formulas like the one just posted, and many more complicated ones than that, didn't fall under my idea of common logic, I could never remember them.
>This is wrong
It is not. Explain what's wrong in my post. Photons move at c in all frames of reference and moving something with mass requires energy to overcome inertia. No mass means no inertia.
How does 1+2+3+4....to infinity = -1/12?
Intuitively it makes no sense. How when you add size to a size you get less size?
Similar to the Monty Hall Problem, I've read the proofs but intuitively it makes zero sense.
Well the point is that 0.9999... only gives the impression to be shorter than 1, but it's not. They are really just different ways to write the same number. the same way 1/3 and 0.3333... are exactly the same thing.
>How does 1+2+3+4....to infinity = -1/12?
It doesn't. The series does not converge and has no finite sum.
It's only in Ramanujan summation that the infinite series is assigned the value -1/12. There is no actual value because it does not converge. It's an assigned value.
light is absorbed and retransmitted by transparent substances, retard
The short explanation is that we conventionally don't assign a value to a divergent sum (such as the summation from 1 to infinity) because it isn't intuitively reasonable to do so, but Ramanujan summation assigns the value of -1/12 to said sum, and different forms of assigning values to divergent sums are useful in different situations (e.g. Borel summation, Cesaro summation, etc.).
Clearly none of you morons took calculus. Here's another one to blow your puny minds: it's possible to prove that some infinite series are larger than others..
>Under common logic, something just short of 1 isn't equal to 1; it's, of course, just short of it.
Here's how to comprehend the whole 0.9999...=1 thing.
Imagine a bowl of rice. You're told to eat 9/10 of it. You're left with a tablespoon or so.
You're told to eat 9/10 of that. You have a few grains left.
You're told to eat 9/10 of that. You have, say, a third of a grain of rice left.
You're told to eat 9/10 of that. You're told to eat 9/10 of that. You're told to eat 9/10 of that. You're told to eat 9/10 of that. Eventually you have to pull out some precision equipment just to keep leaving behind increasingly minuscule bits of rice.
Finally (because you somehow have equipment at hand that lets you do so, you separate out the last molecule of what was once a grain of rice. You accidentally drop it before you can cut it once more and are left wondering what to do, at which point you turn over to a friend who also had a bowl of rice. He exclaims that he really enjoyed eating that whole bowl of rice. You turn and look at his bowl only to see that there are a few grains of rice left. He turns and looks at your bowl and agrees that you definitely polished off that entire bowl of rice. No doubt about that.
Point is that in a world where everything is infinitesimally divisible, near enough is always good enough.
What the fuck are you even spouting off on about, retard? That's obvious, e.g. take a_n = 0 for all n, b_n = 1/n^2, sum from n=1 to infinity; then the sum of b_n is trivially greater than the sum of a_n, and both converge.
That doesn't even require calculus.
Is it physically possible to make a space transborder able to travel at sub-relativistic speed?
If a human manages to reach light speed, which is impossible, will that person become endless?
Okay, suppose you have an infinitely large hotel, and an infinite number of guests check in one Tuesday night. Later that evening, another infinitely large tour bus pulls up out front. (Don't ask me how; you have an infinitely large parking lot, bitch.) Sure, you have an infinitely large hotel, but how are you going to give them all rooms?
Simple. Tell each guest to move down the hall until they reach an unoccupied even numbered room, then have all the new guests move into the odd numbered rooms. Only thing is, it's trivial to understand that you have more guests than you did before; in fact, you have a lot more of them. But you already had an infinite number of guests!
The set of all odd numbers and the set of all whole numbers are both infinite, but according to some branches of mathematics, one is a larger shade of infinite than the other.
USELESS THEORETICAL MATH, BITCHES.
The Oculus Rift or similar technology plus the current level of AI and graphics programming could already create a depiction of anyone's waifu that would fool your brain. It's just a matter of finding enough skilled people who care enough about making such a thing happen.

This guy >>120670830 seemed to be having some difficulty with the notion.
There's still a subtle difference - not in where they end up, but in how they get there.
If i told you to walk a mile or to walk 0.999999999999 miles, how much difference do you think there would be in your final location?
If you were to build a house, or to build 0.99999999999999999999999 of a house, how many bricks would be missing?
You do realize that the first two posts you quote are BOTH MINE?
Refer to >>120670764, where you bring up the fact that "some infinite series are larger than others", which is clearly different from "some infinities are larger than others", not that either point is even related to anything here. Fuck off, you clearly have no idea what you're talking about.
>Let x = 0.9999…
>Then 10x = 9.9999…
>If we then subtract x from both sides of the equation, then:
>10x – x = 9.9999… – 0.9999…
>So, 9x = 9
>Divide both sides of the equation by 9, and…
>x = 1 … which, when we started, we said = 0.9999…
>If i told you to walk a mile or to walk 0.999999999999 miles, how much difference do you think there would be in your final location?
0.000000000001 miles, or 1.609344 nanometers.
The point of a repeating number is that the value does not end. There is no measurable amount of missing space as there is in any finite sequence.
>If i told you to walk a mile or to walk 0.999999999999 miles, how much difference do you think there would be in your final location?
A very small one, but still a difference.
>If you were to build a house, or to build 0.99999999999999999999999 of a house, how many bricks would be missing?
enough so that it wouldn't be complete.
This is like saying 9999999999999999999999999999999999 dollars and 99 cents is equal to 10000000000000000000000000000000000dollars.. The penny difference is still there, eve if it's just a penny.
>that would be discrete
>educate yourself on precursors
Explain. Are you saying matter does not absorb photons? Photons don't just ride straight through glass, otherwise you literally wouldn't be able to perceive glass.
For practical purposes, its the same, but as far as actual mathematics, anything that is not equal to 1 will not be equal to 1 regardless of how closely it reaches 1.
This is more important as far as higher-level mathematics goes, since a calculation that amounts to 0.99 repeating and a calculation that amounts to 1 is different and could, in theory, fuck up other calculations.
Or something, I'm not a mathematician.
You are unable to guide yourself to a location without a variance of at least 10 nanometers.
A house could never fall apart from loading stress or fatigue from a crack less than a nanometer in size. It simply can't be relevant, hell it wouldn't be visible even with a microscope.
>Even if you're 0.999999999999999999999% straight, you still would fuck men.
Firstly, if you're less than 1% straight, that's over 99% gay, so duh.
Secondly, how is it then that you're 100% straight but still don't fuck girls?
>You are unable to guide yourself to a location without a variance of at least 10 nanometers.
Are you trying to imply I am not a perfect machine with precision control to the attometer?
There isn't a calculation in existence where using 0.9999999 recurring instead of 1 or vice versa would change the end result. No matter how many digits you run the calculation to, the recurring decimal will always round to 1.
That's why I was using real world examples, to show how you would always reach a point where any perceivable difference would be rendered insignificant.
>You are unable to guide yourself to a location without a variance of at least 10 nanometers.
>You are unable to guide yourself to a location without a variance of at least 1 cell.
>reality is just a shitty game
Nanometers are still relevant in plenty of cases anon
Your explanation is retarded as fuck, no matter how small the difference, finite differences still exist. Trying to explain away the difference as "well it doesn't matter in real life" doesn't actually prove anything.
The same way [C] threads were fun without talking about it.
>light can't go down in speed, it can lose velocity however
CERN has some interesting articles on their website.
>If micro black holes do appear in the collisions created by the LHC, they would disintegrate rapidly, in around 10^-27 seconds
For every case in which nanometers are relevant, we'll add more 9's until we're past the point at which it matters. You get it yet?
It's not a finite difference. It's recurring.
The difference is 0.0000000000000 . . . . .
This is why engineers shouldn't be allowed to do math.
I'm the anon who started using all the bizarre analogies.
The point was to get you to understand that for every calculation there is a point at which the error rounds to 0 if the recurring equivalent number goes on for long enough, and it always will.
The actual reason for this is that the way people think about place value numbers is wrong. It only works with a finite number of placevalues. With a finite number of placevalues, you have to remember that the place value system is just a representation of a number, and that "infinitely close to X" actually does mean "X" when you're not playing with limits.
no, it doesn't. why is /a/ so scientifically illiterate? that claim derives from the idea of large extra dimensions, an idea from the 90's when they were trying to get around the constraint in string theory of the planck energy being large (compared to the strings themselves). this led to a shit ton of neat mathematical tools being developed, but the idea of large extra dimensions in reality was always patently false, and if you tried applying this idea to reality it would just be wrong, since there are very good reasons to believe the planck energy is big (compared to the strings).
the phenomenological people (experimentally minded people, as opposed to theorists) didn't realize this and in a fit of delusion proposed a model in which they actually took the idea of large extra dimensions mapping to reality as a possibility, and then arkani-hamed, dimopolous, and dvali plus a bunch of other delusional experimentalists published a paper in which a model was proposed which would admit the creation of micro black holes at the LHC's energy levels, and then popsci media took it and ran with it.
in short, it was never a possibility; just experimentalist autism and sensationalist click-bait headlines written by people who have never taken even an introductory physics class.
>not the true GOAT at aesthetics
I'll give you the STE part, though.
>why is /a/ so scientifically illiterate?
No bully, please.
If Mozart was alive what anime would he watch?
He'd only watch hentai, and maybe a few magical girl series if the have cute lesbians.
Implying engineers care about math as a science. We use math to solve problems, in some cases we round 0.99 to 1. It all depends on the order of magnitude that interest us in the given situation.

But the moment you tried talking to her you would realize that she's a fake.
????? i can't tell if you're trolling. physics and math, prior to the mid 19th century, was pretty much developed in tandem. it's only recently that pure math has had a major split with physics, and there are still a bunch of contributions from physics to pure math (c.f. ed witten & his field medal shit). to claim that physics is "irrelevant" to math is to either be profoundly ignorant or to be wanting to deliberately mislead. in any case, i wasn't the guy who originally responded; just took issue with your saying that feynman is "irrelevant"
That doesn't change the fact that we have the technology now. As long as your waifu isn't some ultra obscure character that's never been heard of by anyone, you could even have each waifu get a specific AI with a massive amount of appropriate "sayings" and "actions".
S;G is basically fanfiction mashing a bunch of shit together, mainly the Semi;Colon universe and John Titor's messages. It also mixed in some Dr. Pepper, Moe dolls, Chicken Tenders, Otaku, Gooey Bananas, futa, chuuni, internet culture, grape apes, microwaves, disco balls, pokemon merchandise, cellphone culture, and SCIENCE!
Have a monster.
I don't remember reading any of that.
>If John Titor DID use a time machine then his work is a fanfic of S;G, not the other way around.
but that's a paradox, because the information of john titor would've spawned from nothing.
MFW John Titor only posted online after completing his mission because he wants to be in an anime so he can make posts in /a/ threads about the anime he's a star in.
Normally that kind of bullshit wives tale working would have been immersion breaking, but fuck it. It's a cool concept for a story so it was fun to let it slide.
The only dumb thing about S;G was that they needed to undo so many things to change world lines. Not hacking into SERN should have been enough.
There WAS a wackjob named John Titor in his time line, and OUR Titor wanted to recreate the wackjob's legend to become the REAL Titor, so he posted about it online in our worldline. He's basically a LARPER with a time machine, role playing as a nut from his own time line that he thought could be cool.
Luka's not even transsexual. Luka does not believe he is a girl at heart or anything. Luka simply is in love with Okabe, who is heterosexual, and is depressed by that fact, so he desires to change himself to fit Okabe's desires. Not actually wanting to "be female" but instead wanting to "enable the possibility of being Okabe's love interest".
In the first time around, S;G made it all up. Then John Titor's parents named him after the character and he became obsessed with the show and time travel, and JUST SO HAPPENED to be one of the first people to do so. He tries to predict his own character creation to show everyone that he succeeded, but instead everyone just thinks that S;G drew inspiration for the show from his ramblings. He goes insane from the fact that he's failed to prove that he succeeded in time travelling.
They didn't just want to change world lines, they wanted to be in the ORIGINAL line, to have a chance at reaching S;G.
The world where little-miss-moe has a dad might not be able to reach S;G as easily as the world they came from.
>"I... really don't... want to change back..."
>"Because... Because... If I change back into a guy... I'd have to seal my feelings for Okabe... I don't think I should love Okabe if I'm a guy..."
It's outright explicit, the only reason he wants to be a girl is to love Okabe. He's a self-hating homosexual, not a transsexual.
Then wait until they get a phone or other decide, it'll happen eventually. If they'll have one when Okabe is 4, just have the message tell the parents that listening to Queen and M. Jackson and watching Peewee's playhouse will make a healthy child.
>Hey Okabe, I want to text your mum.
>How about no.
>My plan . . . is foiled!
>Because... If I change back into a guy... I'd have to seal my feelings for Okabe... I don't think I should love Okabe if I'm a guy..
Which she says as a girl who doesn't know what it's like to be a guy. You seem to forget that only Okabe retains memories.
Because he doesn't hate his love for Okabe, he hates that he is unable to satisfy/interest Okabe. He has low self-esteem and considers himself to be worth less than the one he desires.
