Theories of Time Travel

[Okami]

Everything happens for a reason, and if we were allowed to go back and fix our stupid mistakes, the human race might be perfect...And it's not. =/

Wasn't there a theory about going fast enough?XP Some people put a clock in a plane and kept one outside it, calibrated them and they found out that there was a slight difference in the milliseconds when they compared them again.

Simply going as fast as you can in a plane would not effect the flow of time around you. You'd need to go faster than the speed of light to actually effect the flow of time around you, and as far as I know you'd never be able to go "back in time". It would appear to you that everything else was simply moving faster in time than you (if you could somehow observe anything whilst going faster than the speed of light).

Even if human beings could go faster than the speed of light, they would certainly die as soon as they achieved this and they would not go "back in time", which again makes this thread's original scenario impossible to begin with.

die not because of a gene but because our DNA ages so much through all the replication of cells it is no longer well enough to keep us alive

Death is an Illlllllluuuusssssssssssiiiiioooon.

There is no such thing as perfection. Short, and sweet. Everything needs improving, even if it seems that is doesn't, it does.

I believe in the first theory, because IF, we have the ability to time travel, would everything already happened since, well lets call it history, since history takes EVERYTHING in account, doesn't that mean it also takes in account the fact someones builds a time device, and you, or someone else goes through the device, it actually working, and that human is altering something in the past, and history would of took all that in account already.

As the turtle said, (something in the lines of this):
Past is history future is soon? and the now is a gift that's why they call is present
That's not exactly how it goes. But Kung Fu Panda is awesome, go watch it nao.

I don't think time travel will ever be possible or even feasible, so it's not really relevant.

[Mewtwo Ex]

I am the only to pick that something will change.

Basic logic dictates that it would.
Example:
Today you thick what you did yesterday.
You staid yesterday at home and being bored.
But a friend uses his time machine and goes back a day.
But your friend calls and tells you to go for a walk with him and you go out.

Therefore if you understood my logic you should understand that the friend prevented you from being bored all day.

[Greencat]

No, you prevented yourself from being bored by making a different decision. :d

[Mewtwo Ex]

Yes, but if my friend didnt ask me i would not go out and have that decision in the first place.

[Greencat]

This is assuming Time Travel is possible. ;P

[Mewtwo Ex]

Nothing is impossible if you ask me.It could be in the future when it is available. The factor is when the event happens.

I'm going to say again that even if time travel was possible, it would kill you instantly.

[Mewtwo Ex]

True. But if you exist outside the time line you should be fine.

[Zafur]

Yeah, I know planes would... probably never reach speeds high enough to affect time, but it was just an example from something I saw on TV.
It would make things interesting though, if it worked.

[Enzo]

True. But if you exist outside the time line you should be fine.

If something didn't exist within the 4th dimension (time), then why would it be interested in traveling through time? And if it DIDN'T exist in time, how could it travel through Time anyway?

That is, everything has to exist within Time, since it wouldn't be a dimension otherwise (everything exists in all dimensions somehow, even if in a very strange or hard to see way).

Well, someone from the future might have went back to ancient times and somehow influenced life from the past. They might have taught Egyptians how to build pyramids, they might have taught humans about herbs and cures for diseases that even us in the present don't know about, information about the past is very blurry, we almost know nothing, and, remember, people in ancient times knew stuff we don't

This is impossible. All information must originate from someone. If the future people teach the past people something thus establishing the knowledge of said something in the time line, then how would the future people teach the something to the past people if they were the ones to historically "create" the information. This is called Can-Not Because Has-Not theory. Said and done. Pretty much case closed.

[RenegadeShroom]

I certainly hope that time-travel isn't possible - there'd be too many people screwing around with the past and end up ripping apart the entire future course of events, and that probably includes people being born. I say, if it is possible, that as soon as you go backwards in time, you create an alternate universe, which exists in sync with our own. This actually isn't my idea, but it's off Star Trek, and it makes me worry less about some idiot erasing me from existence.
