Re: Time Travelling.

Except that he's right; scientists have discovered something that can travel through time.

I don't remember the details, but they sent some sort of signal to another place far away. The thing is, the receiver received the signal before the sender sent it.

I'd so very much like a link for this, including the 'atom that uses the 5th dimension' part.

Re: Time Travelling.

If you go back in time, and kill Hitler, that would create an alternate reality where Hitler was killed.   Future you would have no reason to back in time, because the you that killed Hitler came from anther dimension, where Hitler was never killed by you.   Basically, when you go back in time, and change something, it creates another reality, so that both results, still can exist.

noooooo that would be a paradox. what you do in the past has already happened and is inevitable to haaaappen.

Re: Time Travelling.

Time travelling is possible, but only in one direction, which is the future. The thing is, completing a successful trip to the future takes a lot of space, energy, money, and time, even for the people travelling. If I went on a super fast train, about 99.8% of the speed of light, and this train would loop around the earth for around 100 years, to me it would only be around 2 years or something. Why is this? If you are going on a train at 99.8% of the speed of light, and you walk- no, run to the front of the train, doesn't that mean you are going faster than the speed of light? No. The Universe can't tolerate that and decides to slow down time, so such a task isn't possible.

tl;dr Time travel into the future is possible if you go really fast

Re: Time Travelling.

Time travelling is impossible.   Period.   There's no magic or science that can change the past.

Are you talking about the Neutrino experiment at Opera?     They thought they found that the neutrinos fired travelled faster then the speed of light which would indicate they could travel through time..  

This was proven wrong. It turns out there was an error in the measurements / equipment used (Which most people thought would be the case..)

So as far as we know, there is no such particle..

And Patience Is Key is right..     Time Travel already happens all the time, in a sense.

The faster you go, the slower time goes by.

The same with mass, the heavier the mass (And therefore the stronger the Gravity) the slower time goes by.

So therefore, time is not equal through out and universe and can be bent and slowed down..   Therefore you can age slower if you do one of the two above circumstances, but you wouldn't notice it. Because everything is slowed down, including your perception of whats around you, so it would all seem like it always does. But when you got back to earth, everyone would be older than they normally would be (more forward in the future) compared to you, if you were in one of the above two circumstances for a long enough time..     if that makes sense..

I don't believe that's correct... the equation for time dilation is

t'=t/sqrt(1-v^2/c^2)

which does not have any mass in it.

Edit: Oops, I'm using special relativity. Gravity fields do warp time, but it is not based off of the mass of the object itself primarily, but mainly the mass of nearby objects with significant gravitational fields.

I only heard about the experiment in passing, and did very mild research into the matter. However, where did you find this information? I tried looking it up, but I can't even find my own source again... I don't know what I googled before. >.<

I just found a Wikipedia article on the matter, but Wikipedia.

Oh he totally BSed the fifth dimension part, probably attempting and failing to combine it with the concept of the fifth dimension being time, but the study was very real. Of course, if what Everglade said is true, then it doesn't matter.

Re: Time Travelling.

Why do people think it could be possible for a start? I mean.. Nothing in the universe could make it possible. It goes against nature and realism..

true it goes against nature ant realism, but so do black holes and they exist!

I think that there are infinite dimensions
if anything can happen differently then there is another dimension where it does, counting for each possible different outcome.
It may be possible to access these other dimensions, in which case a new one would happen where you didnt, and one where you almost did, then one where you decided to stay, and one where it killed you, then one where you did it in a different way, and so forth

then again this is my opinion and I have yet to meet any one else who shares it (over active imagination?)

There seem to be many people that believe this; I believe in determinism and as such that there only is one possible history, so there is no need for alternate dimensions with the other possibilities because there are none.

Re: Time Travelling.

although time travel is impossible it is possible to travel somewhere before you should get there

http://www.reuters.com/article/2011/09/ … FH20110922
that link talks about particles that travel faster than light

one plausable theory to this is that the particles are 'hopping' across our dimension.

http://www.youtube.com/watch?v=3pAnRKD4raY&feature=plcp
at the end of that video with the paper thing is an easier way to explain that theory

Re: Time Travelling.

There hasn't been a single hint of time-distorting material nor phenomenon, it'll never happen.

Re: Time Travelling.

the equation for time dilation is

t'=t/sqrt(1-v^2/c^2)

The Lorentz factor is quite interesting.

Gravity fields do warp time, but it is not based off of the mass of the object itself primarily, but mainly the mass of nearby objects with significant gravitational fields.

Specifically, gravitational time dilation.

You have a screwed up view on dimensions...

reality /= dimension

Lolno. If you're looking for hints, then the simple fact that we theorized time travel could be taken as such.

Yes, thats what i was getting at in my post

Anyways, i thought most of the players on Everybody Edits were in there early teenage years, or even younger...   So how the heck do some of you know so much about Special Relativity and General Relativity..     I'm shocked!

Go tell this to your teacher...   you will be moved up a year...     or a few!

you do not understand.   it would not be a paradox, because you created another "history" that split off from the one you originated at.   In your time, hitler existed, and you left for another dimension.   In the other time, someone from another dimension visited, killed hitler, and WW2 never happened.   It would not be a paradox, because, even if you still born, in the future, the you that killed hitler, came from a different dimension.   this allows both to happen, paradox free.

The concepts mentioned in this thread are fairly simple and don't actually require any real knowledge of physics or mathematics.   Also, some of us may well be 20+ having studied physics for a fair while.

A lot of the people on the forum are quite older, or so it seems. I know I'm not young enough to fit into that category...

You guys are only arguing which theory is correct. The fact of the matter is that tons of physicists who know a hell of a lot more than you guys have been arguing about the same thing for a while, and have made little progress. They don't know whether the answer is paradoxes, dimensions, some combination of the two, or something entirely different.

Re: Time Travelling.

backwards time travel is neigh-impossible
forward, however, is possible
if you really want some cool info on the subject, try watching steven hawking's into the universe, the second episode is all about time travel, it's some really cool stuff
