Time Travel, Worm Holes, Parallel Universes?

Question

Theories, how they work, all that shindig.

Answer 1

Time travel and worm holes:

Just like space, time is considered to be some sort of plane. When a hole opens up between these 2 planes, it is called a worm hole. If you can go through it, then theoretically you can travel between the time that you are in and the time that the worm hole goes to. Some people think that black holes are worm holes, although, they cant prove it cause, you cant go into a black hole without being crushed into the size of an atom, or being ripped apart. A black hole is a star that has collapsed on itself.

Parrallel universes:

This is more of a sci-fi thing than anything else. Watch Sliders.

Answer 2

Time travel wormholes and parallel universes are a fascinating subject. and they are all very interconnected. you see the only problem with the whole time travel thing is paradoxes, you know the whole if you went back in time and killed your grandpa, then you wouldn't have been born, which means you couldn't have killed your grandpa, which means you would have been born. and on and on and on.

now the only way that could work out is the many worlds theory which basically is that every choice you make create two (or more) worlds in which each choice is carried out. so then you would go back in time kill your grandpa, and there would be two worlds (or parallel universes) one in which your grandpa is still alive, and one in which your grandpa is dead.

now the only way to travel through time or to parallel universes is through a wormhole. which is basically a black hole and a white whole stuck together connected to another black whole and white hole stuck together (a black hole sucks in matter and a white hole releases it) a wormhole can theoretically move through the fourth dimension (time).

for more info on this theory you can read up on the many worlds, and string theory. and watch the movie Deja Vu, or the show Strange Days at Blake Holsey High.

any more questions feel free to email me.

Answer 3

Actually they are all interrelated. In order to achieve time travel you need worm holes, and in order to avoid paradoxes you need to accept the theory of parallel universes (eg. Grandfather paradox)

Answer 4

The TARDIS of course! If you see a blue box, flying anywhere in the sky, you shout for me Nico, you just shout.

Answer 5

TIME TRAVEL - Not possible to physically travel back in time, nor ahead because there is no physical "past" following along behind us, nor any physical "future" awaiting us up ahead. Time travel of a sort is possible through Einstein's relativity where you blast off into space at near the speed of light. When you return you'll return to a time significantly advanced from when you left.

WORM HOLES - Again, certain Einstein equations allow for such a thing. Essentially a worm hole would be a short cut between two widely separated locations. If you place two dots on a flat piece of paper about 6" apart and then fold the paper in such a way that the two dots are directly opposite each other you'll see that they're now much closer than 6". Substitute the flat piece of paper for spacetime and you get the general idea of worm holes. Right now they are strictly theoretical.

PARALLEL UNIVERSES - By calling up Heisenberg's Uncertainty Principle concepts have been developed stipulating that every time a decision is made, like you turn left instead of right at some crossroads, or an atom "decides" to decay, another universe branches off in which the opposite decision is made.

Answer 6

The only real answer is - no one really knows if these things exist.  And if they do, we certainly do not know how they work.

There are some believers that Time Travel could be possible, but one of the best arguments has always been "Why have we never encountered a time traveling tourist visiting us from the future?"

Parallel Universes?  Who knows?  I certainly wouldn't rule it out.  The universe is a mysterious place.

Worm Holes - I know only what I've seen on Star Trek.

Answer 7

Whatever I'll go ahead and be the nerd I am. XD

I belive our universe is in an a black hole. The sky is black, everything floats, why not a black hole??

Einstein said it was impossible to teleport. =P

There are no such things as parallell lines. They eventually stop in this universe or intersect.

Einstein said you can go back in time if you went the opposite way around the earth was rotating at the speed of light.

Nothing is 100% accurate. There is always a possiblility of change. =P

Magnetic levetation is the future of monorails.  <----- (*My prediction*)

Answer 8

No. Time travel is not possible. If you want to go somewhere, that place has to exist. If you want to time travel to 1 Jan 2020, ask yourself, does 2020 1 jan exist now so i can go there? The answer is no.

You can only time travel somewhere that exists in the present. You can't time travel to 1 jan 1900 or any other date because it simply does not exist in the present.

Answer 9

I too believe we are inside a black hole, and every black hole can have infinite amounts of universes within, but is impossible for them to intersect.

the rest is very difficult to explain here on YA. I only have a simple understanding about it and always find new ideas. these are some of the strangest ideas imaginable.

I really suggest researching each topic individually.

Answer 10

Time travel is only allowed in the relativistic sense.

Basically from the observers perspective frame dragging appears to result in a violation of the constant speed of light in a vacuum.

A worm hole is sufficiently warped space-time to result in observer subjective relativity violations but not actual relativistic violations.

Parallel universes is a dechorence approach to understanding wave function/ collapse event.

It essentially builds on Faymens sum-over-paths interpretation that yields the same predictions as Schrodinger wave equation but avoids things like a super-positioned cat trapped in box simultaneously alive and dead awaiting an observer to determine its fate.

Instead in one universe the particle decays and in another it does not.

Some propose a solution of thought experimental paradoxes by appealing to parallel universes.

Where by you do not travel into your universes past but instead create a probable universes existence through dechorence and only kill that parallel version of yourself/grandfather/mother or what ever, which affects only that parallel universe of which you are now a part.

In this regard theory states that all possible wavefunctions exist and we are only coherent to a particular "collapsed" state of the infinite wave functions.

The common analogy is to think of the fact that when you listen to the radio you are tuned into a single frequency, however the radiowaves for all the other stations are still present, you just are not tuned into therm.

Time travel in this model is simply tuning to a different station, but the stations are PROBABLE not actual, that means you have to cause their existence by increase the probability that they will become existent in the physical sense.
