Oh, another thing about time travel ... if you did travel through time, would it not return you to exactly the same place in the past? Like, if the universe was on a 3D grid or something, you'd be in the same co-ordinate, but since the universe is moving you wouldn't end up in the same place on Earth. You'd probably end up floating in space.

let's just assume that the time machine is a device where you enter the coordinates x, y, z, t and push a button..

Ah, but then you'd have to create some sort of formula to account for spacial drift

Which now sounds like you're going through a stargate ...

I've never heard that. What's the theory behind it? Doesn't make sense to me - it'd be like saying that after you've built a car and driven north, you can only drive back as far south as where you built it.
check out the viideo i posted earlier

Time is something we have invented - proven.
Time is a natural phenomenon, such as gravity - not proven.

If there is no such thing as time, no timescale - we can't either go back or to the future. If...
You're wrong. Time is a dimension, it's not simply an invention.

I can't be bothered with watching the video, but would it have to be more of a rule than a ... Law of Physics? If you go back too far, how would you get back ... It would all depend on what type of Time-Machine we're talking about. Is it a portal that you walk through, a machine that you ride in, or a magic watch that magically zaps you through time.

Since no one from the future has ever 'visited' us, I think it is safe to say that time travel will never be possible.
Sorry, but this is a pretty weak argument. All we can say is that no one from the future has ever visited and then gone round shouting "I'm from the future!".

Just have a seperate node on earth, one which returns the location of node to computers on the time machine. :woo:

not that that explains people traveling back in time but the theory is there.

That video was pretty cool. It makes me want to get involved :p: ... its wayyy too confusing though. He says how the future him could send stuff back to himself. What would happen if he decides not to send things back to the past when the time comes that he supposedly sent the stuff back?... Wouldnt that mean that energy is coming from no where because it just appeared - argh this is confuuuuuuusing. :woo:

what about that thing where you can only travel back in time as far as the date when the time travel machine was first invented?
or something like that.
then we would but we havent invented it yet so we dont know.

May they have visited us, but nobody has revealed this yet. They kept it a secret for unknown reasons.

I don't think you would.

Where would you have the origin of these coordinates? The centre of the universe? We are at the centre of the universe, but so is everywhere else.

If you just imagine yourself as staying still and everything else in the universe moving around you, then you won't need to bother with the spacial aspect. Maybe. I'm not sure.

I don't think it's likely that anyone would mess up the past if they were to travel back in time.

I mean if you go back, you were there at the time. So whatever you do when you go back, you've already done! So you can't "change" events because events have already been influenced by what you do, since you've done it already.

This made sense to me but will probably be a load of crap to anyone else

Why is it that they will only be able to travel back to the moment they first invent one?
watch donnie darko! worm holes is the answer
(thats not a totally sensible answer by the way)

im assuming the world will implode soon after time travel is discovred as it would cause many contradicting senarios, causing the universe to implode, causing a new big bang, and off we go again, a new universe, and intelligent beings will always be doomed to destroy their own world when they get scientificly adavance enough to time travel

what about if when you time travel you end up in another universe then it wont matter what you do because it wont be a paradox.

How can this be proved?
