Time Travel

Is time travel to the future possible? and how?

And this i have been pondering on for a long time...

If you travel to the past to kill your grandparents, would you never exist? And if so, who killed your grandparents if you never existed?

i dont think its possible at all

but thats probably just because we dont know how if you can yet(lol)

I am yet to find a written 'theory' or 'article' on how time travel will be achieved. I have found ones on antimatter, warp drive, magnetic drive, transporter, but not time travel.

Ok, now, allow me to begin the end of this thread.

I'll just focus on time-travel.

Time Travel is still theoretical, but we have done a variety of it. We cannot travel into the past, nor the future, but we can slow it down. Gravity. I'll give you the example:

Say you have 2 people, born at the exact same date, time, etc. etc. etc., well, If you stuck one on top of a mountain, and stuck one deep down in the sea, let them sit down there for a month, brought them back to the same sea level, and examined them, the one who lived in the sea would indeed be younger, (not by much mind you, but more like micro-seconds).

An even better example that my friends and I have come up with:

Say that we do create a ship capable of traveling a lot faster than now (not warp travel, but just fast), and you circle the Earth (while still in it's gravitational pull) a few thousand times, for about a month, you land on Earth, years will have passed by.

Of course, this is all theoretical, but we do know that gravity has an effect on time.

PrankishSmart-- Read Steven Hawking's Books. You'll find quite a lot of answers there.
STV12-- There are quite a lot of theories on Time Travel, I'll just name the ones that seem more important;

-If you travelled back in time, you would cause the universe to collapse (I don't see how though...)
-If you travelled back in time, you would cause an infinitie loop, because you would have done this in the past, causing you to do it again, etc. etc. etc. (But that doesn't explain the second you that would appear in that specific time frame)
-Multiple Time Lines. Travelling forward or backward in time will cause you to jump into a different time line, and once you leave yours, there will be no returning to your own time line.

Theoretically, time travel is possible through the use of black holes and other similar singularities. The problem is that everything that enters a black hole is crushed to it's original atomic structure. Hense, the reason no one has tried it. This relates to the gravitational theory of timetravel (what has greater gravitional force than a blackhole which draws even light into its singularity).

Also, if you wanted to travel to the future it would be quite simple (considering you could achieve the speed of light). LOL...Anyway, it has been proved that the closer to the speed of light that a spacial body travels (i.e. a space shuttle or starship) the faster time passes. I believe the relativity of it is something like for every six months one travels at the speed of light five hundred years would have passed on Earth. This is evidenced by our own NASA shuttles which must reset their chronometers after reaching space since they are inevitably a few minutes faster than Earths.

This is probably how the slingshot theory in the ST TOS movies work. When a starship in ST enters subspace, subspace nulls the effects of "time travel" on the ship. But when the starship travels at light speed velocities (i.e. warp velocities) outside of the subspace layer, it is subject to time travel. How they explain the backwards movement leave much to be desired though.

There is also the theory that there are several "timelines" which one could travel to. The problem with that is if you wanted to travel back through time and assassinate Hitler (and assuming you could return to your own timeline) you still would have changed nothing on your own planet. Presumably, you could meet yourself in an alternate timeline as well which could also have catastophic results since naturally there should only be one of you in that timeline. Theoretically, if you and your counterpart occupied the same space at the same time, you could destroy each other, like matter and anti-matter.

In any case, time travel is no where near possible...but it's fun to theorize...

Oh and what you describe above is called a paradox. A theoretical looping of cause and effect. If I kill my father before I am born, I can't be born hence I can't travel through time and kill my father and I will be born hence I can travel through time and kill my father. The loop would be never ending, creating havoc for whatever force holds the universe together.

I once posted in a massive discussion on the time travel theories. I'm not sure if the topic exists in this forum anymore or not, but many people have different theories to different aspects on Quantum Physics. I actually have a unique theory myself if anyone wants to contact me (Via email to [email protected]) if you'd like to hear it. But in all honesty I do believe that time travel may be possible.

And the thing with killing your grandfather and stuff is known as a paradox. That too differs between theories.

Lt.BirdGod · **Wed May 28, 2003 1:10 pm**

I think we've basically covered everything. Oh yeah, light speed is "impossible". There, that's everything.

Dax Orien · **Wed May 28, 2003 7:00 pm**

Well that's a little closed minded. Couldn't you believe that it's possible? I mean, don't you think that anything could be possible? In theory of course.

PrankishSmart · **Wed May 28, 2003 10:34 pm**

IMO, time travel is a sci-fi fantasy, unlike something like transporters which is more theoretical, and at the moment at least partially practical.

Captain Michael Pike · Captain Joined: 14 Jul 2001 Posts: 597 Location: PA

Yes...but thirty years ago transporters were sci-fi fantasy that no one thought could work. Not only are they now considered a theoretical possibility but scientists have even succeded at transporting...oh what was it?...a proton or electron or some other damned thing...LOL!

oooo. They succeeded in moving it so far that it would take an Electron Microscope to see it.

So far.

according to Einstein (i think it was him) if the Earth changed the direction it was spinning........ we would go back in time..... or if you flew the opposite way of the earth in space fast enough you would go back in time......

Captain Michael Pike · Captain Joined: 14 Jul 2001 Posts: 597 Location: PA

That's not Einstein...that Superman the movie...

Regardless, if the Earth's rotation changed then it would like spin out of its orbit causing a catastophic change in gravitational forces throughout the solar system. In all likelihood, our entire solar system would cease to exist, at the very least Earth and its neighboring planets certainly would.

It is possible that Einstein said that first, I mean, I've heard ideas in other places that were from Stephen Hawking.

Kyle Reese · **Fri May 30, 2003 11:06 pm**

I think time travel is possible, but i can't explain what would happen if you did. Or how you would get back

Don't take life too serious, you'll never escape it alive anyway

You'd like to think so except....Einstien was no genious when it came to things outside of theoretical physics. He was horrible with reading comprehension and worse with mathematics. Aside from theoretical physics, about which I know quite a bit, I'm sure I could take Einstein in a general test. Oh yeah and where's your sense of humor?

Dax Orien · **Mon Jun 02, 2003 9:14 am**

Hey hey hey. Now let's play nice, children. You know that if you really start fighting with each other that they'll lock this topic up and such. And then they'll delete your posts. And then where will this arguement ever truely expand too? So let's just keep in line with the topic: TIME TRAVEL.

Einstein did have his flaws and I know that there were and are better Astronomical minds, but Einstein wasn't all theory you know. So just don't call him a blatent theorist.
