I'm nowhere near geekship(don't listen to my classmates-they know nothing of true geeks), but that has something to do with Einstein's theory of relativity?

I personally think that time travel is possible, and subscribe to the theory of "Everything will be alright, don't worry about messing up time". In other words, if you tried to kill, say, Hitler when he was a baby, World War 2 would still happen, because you would fail to kill him somehow. This also solves the Grandfather Effect problem.

Good luck building an energy source that big.

dude just get a flux capacitor or something like that

also i heard theres this theory which makes the whole grandfather thing possible

pretty much theres points in the linear motion of time on which we travel where the line splits
pretty much there is a place in time for every possible way everything could happen
so the time we ride (4th dimension) is like out 1st dimension and all this jazz (5th dimension) is like the 2nd dimension

then if you bend the next dimension you get to travel really quickly between points in possible time

in other words read flatland

You've read about dimensions? Yay!

0th dimension: .
1st dimension: —
2nd dimension:
3rd dimension:
4th dimension: The fourth dimension is what starts the branch of space time dimensions. It is also nearly impossible to get into this dimension, but if you do, you could time travel, or continue to the multiple-timeline dimensions.

That's all I remember.

I just traveled 50 seconds forward in time as I wrote this post aren't I cool?
By the way, going fast just makes you perceive time slower, it doesn't actually slow it down

It may indeed be possible, but it would take a long time to plan out. The smallest change might kill 1 billion people in the future, let Hitler take over the world, etc.

Never mind, of course it's possible, if you go 88 miles per hour in a Stainless Steel car with a flux capacitor and some plutonium fuel you got from a gang of terrorists.

Nice BTTF joke. 

Unfortunately, we need to go close to the speed of light. Which is practically impossible.

I see that you are interested in wormhole theory. Welcome to the club.

The only thing CLOSEST to time travel is just sitting there and watching a two-and-a-half hour movie. That makes time fly REAL fast.

I have been researching worm holes:

In physics, a wormhole is a hypothetical topological feature of spacetime that would be, fundamentally, a "shortcut" through spacetime. For a simple visual explanation of a wormhole, consider spacetime visualized as a two-dimensional (2D) surface (see illustration, right). If this surface is folded along a third dimension, it allows one to picture a wormhole "bridge". (Please note, though, that this image is merely a visualization displayed to convey an essentially unvisualisable structure existing in 4 or more dimensions. The parts of the wormhole could be higher-dimensional analogues for the parts of the curved 2D surface; for example, instead of mouths which are circular holes in a 2D plane, a real wormhole's mouths could be spheres in 3D space.) A wormhole is, in theory, much like a tunnel with two ends each in separate points in spacetime.

There is no observational evidence for wormholes, but on a theoretical level there are valid solutions to the equations of the theory of general relativity which contain wormholes. The first type of wormhole solution discovered was the Schwarzschild wormhole which would be present in the Schwarzschild metric describing an eternal black hole, but it was found that this type of wormhole would collapse too quickly for anything to cross from one end to the other. Wormholes which could actually be crossed, known as traversable wormholes, would only be possible if exotic matter with negative energy density could be used to stabilize them (many physicists such as Stephen Hawking,[1] Kip Thorne,[2] and others[3][4][5] believe that the Casimir effect is evidence that negative energy densities are possible in nature). Physicists have also not found any natural process which would be predicted to form a wormhole naturally in the context of general relativity, although the quantum foam hypothesis is sometimes used to suggest that tiny wormholes might appear and disappear spontaneously at the Planck scale.[6][7] It has also been proposed that if a tiny wormhole held open by a negative-mass cosmic string had appeared around the time of the Big Bang, it could have been inflated to macroscopic size by cosmic inflation.[8]

The American theoretical physicist John Archibald Wheeler coined the term wormhole in 1957; however, in 1921, the German mathematician Hermann Weyl already had proposed the wormhole theory, in connection with mass analysis of electromagnetic field energy.[9]

As you can see it is another theory for time travel and is theoretically possible.

ok dude it looked pretty suspicious with all the [#]s but i just looked it up and you pretty much copied all that from wikipedia
even the picture man

man did you even read it

Actually, the closest thing to it is to get near a large energy or heat source. Remember, E=mc2.
I love the wormhole theory!

But my favorite theory is the Kerr-Newton black hole. It's charged with electricity or energy (I think), and it rotates. The electricity or energy may speed up the hole's rotation, changing the time around it, also distorting it.

No, due to the grandfather effect.

When you go back in time, you could kill your own grandfather before your parents were born, thus preventing your birth, but if you aren't born you won't go back and kill him, so he will live, so you will be born, but then you can go back and kill him, etc.

that would only happen if you killed your grandfather or other down your family tree. if you didn't, what's stopping you?

Everything. Like I said:

Of course, even going back in time and breathing air or otherwise displacing anything at all, whether it be as small as a single atom, presents a problem. Even your presence alone presents a problem if you weren't "meant to be there" in the current universe's timeline.

Technically - the closest to time travel is sleep...  I do that
---------------
Anyway, If someone go's far enough into space they can see the earth as it was back 9000000 years ago!  Now that's time travel - only you would need a massive telescope/magnifying object

I was in a hurry 

So I didn't have time to write it all

Gravidy bends right? Well with your therory we all wou8ld be sucked into the mass before we traveld, most effictive would be a white hole

I say not to do it. It could destroy you and possibly everyone else. It may be possible, but you should not even talk about it.

This is starting to half-scare me.
