I'm talking about basic theories, absolutely no math involved in what I'm talking about, thanks though(?)

Think of travelling through space like walking across a rug.
You can either walk through the rug like most people do, or you can bend the rug and create a loop which shortens the distance.
This bend is the wormhole between two black holes.

First off, wormwholes!! We have no proff of their existence, though they might be able to exist, in the string theory world.
Einstien actually suggested wormwholes might be possible, but due to the fact that we live in a 3d world, we might not ever be able to visit them, since they could require extra dimensions (This is not believes of einstien, just one of his many suggestions, nothing he believed in himself, or at least not that we know of)

Time travelling! Well travelling back in time should be impossible, though travelling through time should be possible. 2 ways!

1. You travel by the speed of light, now the only problem here is that the only thing that can get to this speed is pretty much a foton, everything else, can get close to it, but never hit the exact velocity, or at least not with our modern technology
2. You could go near the center of a black whole, times seems to slow down the closer you get to a black whole, and theories says that in a black whole there is no time. But by travelling very close to a black whole, circulating around it for a X of time, and then going back to earth looking at your watch and then earths watch, should then show a difference, i am not sure of how much the difference will be, since it depends on how far you are from the whole. Also this will also be pretty much impossible, since the black whole is quite chaotic and the mass so dense, that it will have torn you into pieces as soon as you get a bit to close to it. But imaginen that you had some sort of spacecraft, which could resist the pressure, well yeah sure then it should be possible. But gl hf with that

read the fabric of the cosmos by brian greene. he has an amazing knack for explaining time travel to the lehman. his first book (the elegant universe) is very good read also.

^^read part 2: time and experience

Yeah I get all this now thanks
Watched some Stephen Hawking stuff about the "Orbitting a black hole" theory

and the speed of light theory is valid as well thanks, but you only need to reach 90% of the speed of light before time begins to slow to protect the ultimate speed (speed of light) barrier. As you get nearer the the speed of light, say 99.9% like they did with the particles in the underground lab in Switzerland forward time travel is much more apparent.
Thanks



tyvm i'll look at it

ur worst mistake is following guides and someone elses theories as if they were actually true

now about the time travelling its all about how fast ur moving compared to everything around you.. the faster u are moving the slower the time will pass..

so say, u may not believe this, but actually even on a car if u travel for 3 or 4 hours at 250kms an hour, u will be younger than what u would be if u hadnt done it..

about the speed of light, thats used as a measurement quantity of how fast u need to go to slow the time by X.. and in "theory" when u reach the speed of light the time stops.. but thats not true, cause the speed of light is not infinite..

for the time to stop completely u would be need to reach infinity speed, or instant dislocation and for a certain amount of time, but since u cant keep at instant dislocating urself (cause when u dislocate its to one place, then u stop dislocating and will have to dislocate once again), its impossible to stop time..

with this said, it makes it clear for u (i hope) that u CANT travel in time, all u can do is slow ur own time compared to everything else..

So to do what everyone wish (travel in time).. its not rly going back to time.. its to keep slowing ur own time for a certain amount of time (hours, months, years), and then stop doing it.. when u look around everything will be in the future (ur view)..

now some ppl also believe and defend the idea that says that u can do this in ur own mind.. u can slow time in ur mind .. but thats too much for the topic i guess..


on a side note: theres rly not much to talk about in here, theres no reason to talk about the U shape of the universe or w/e theory, nor theres a reason to talk about anything not related to velocity! The fastest u move the slower will pass the time for u! and thats all..

Time travel is supposedly impossible in the scheme of special relativity. In order to travel in "time" you'd need to travel faster than the speed of light or slow down slow enough so that all other particles in the universe obey universal laws of energy, yet your own motion does not.

I might be wrong. I honestly don't know. I just know that the speed of light and the rate of entropy are basically the two barriers that you'd have to somehow bypass.

as I said on the post above.. speed or light is nothing compared to how fast u need to move in order to stop time.. and going back in time happens AFTER u reach the stop time point..



all u can do is slowing ur own time (for a certain amount of time, say 1 minute) by moving faster than things around u, and when u stop u will be say 5 minutes in the future, although u just spent 1 minute of ur life!
