Time Machine
Now I know that a time machine seems very improbable, but I heard that somehow they have come up with a way to make atoms spin faster than the speed of light. If the theory of traveling faster than the speed of light will enable you to go forward or backward in time, and if it does it would be hard for us to keep the same matter composition. Anyway, if we could have time travel what would happen?
I think that our world would be almost non-existant because we could shape the past however we wanted it. This would be a paradox because the past, present, and future would all be changed and the future that you knew would no longer exist. However, you may think that we've had strange things happening to us that appear unexplained. How did da Vinci come up with ideas for tanks,and helicopters when they where 500 years away? Maybe some people from the future triggered world war 1 which led to the holocaust and world war 2. Why did people go insane and burn down the greatest library of knowledge and trigger the dark ages? It is unlikely that there has been any involvement by people from the future or that a time machine will ever work or be invented simply because of strange space-time occurences and rips.
Also, I heard a theory that aliens are evolved humans from the future and UFO's are their time machines. I don't believe this but many may find this interesting.

Time travel is inprobable. The speed of light is a universal constant and nothing can move faster than it because light is pure energy. I believe that is something did somehow move faster than the speed of light, it would create a atomic reaction several billion times the strength of any bombs we have ever seen.
I'm sure Tal can move the speed of light...
'The speed of light is a universal constant and nothing can move faster than it because light is pure energy.'
The speed of light isn't a universal constant. The maximum speed (186,000 miles per second) is. But the speed of light itself can be slowed down under certain conditions... I think they've succeeded in slowing it down to around 30 miles per hour in the laboratory.
Light is not pure energy. Light is just photons shooting blissfully through the air.
Anyway... there are theoretical particles called tachyons. They go faster than the speed of light, and hence travel back in time. But no-one has found explicit evidence that they exist. They're sort of like gravitons (particles that control gravity) in that sense; physicists suspect that they exist, but we haven't found any yet.
Oh, that reminds me: we do have evidence of things 'going' faster than the speed of light... much faster. Instantaneously 'traveling' across several miles.
Basically, a quantum particle can be 'entangled' with another quantum particle. When one spins clockwise, the other will spin counter-clockwise. And what they've done is entangled two quantum particles, seperated them by several miles, and spun one. The other spins the opposite direction instantaneously. And physicists have absolutely no idea how this works. They can't find any particles being sent between them... but there has to be *some* sort of information being relayed between them, and it travels faster than the speed of light.
One more thought: there are 3 ways that physicists think time travel could work. I've forgotten them, but they were all pretty improbable... like creating a small bar (maybe 1 foot in diameter, I dunno) with infinite length and infinite mass and traveling around it at certain trajectories in a space craft.

I've thought A LOT about time travel (especially BACK in time) and I could rant about it for pages.. but I won't, due to the fact that I'm sleepy, but also that it can be summed up to a few lines... I think it would be impossible. Because, say someone was sick enough to want to murder his mom when she was a kid, so that he never had to see her again. Ok, so he does. Now... think about what just happened. He killed his mom before he was born. Who gave birth to him in the future so he could travel back? And since nobody gave birth to him, who did kill his mom anyway? Or another theory... say someone went back in time and murdered Hitler long before he ever did anything. How would the future look like then? If all those people were spared, if the nazis never had appeared... the world would just not be the same, and the guy who murdered Hitler may not even have been born in this "new" future, as his mom and/or dad could've found someone else to love and have kids with, cause of all the people that weren't killed... and so forth... and now I started rambling anyway.. hehe.. well... I dunno... any comments on my "theories"? 
Phoenix, you are right.
Wouldnt that create a *crash * loop?
ye know:
A guy travels back in 2005, he kills Hitler, Nazi's dont appear, and the guy doesnt need to travel back in 2005 because hitler is dead...
So the guy disappears and hitler isnt killed, so he travels back in 2005, etc....

Yup. c is a solid speed limit. Not only can nothing with any mass go that fast, but any notion of simultinaity must be separated by the distance over c.
But hey, have any of you guys seen the "philidalphia experiment"? The movie is o.k., but I mean the documentary. Prof. Tesla accidentaly found a way to "step outside" the universe. Doesn't look like a good idea though....
In some ways it seems like it may happen frequently, in more subtle ways. Ever had a deja'vous , or somehow knew something you had no way of knowing? I would't be suprised if some accounts of ghosts were actually live people projecting thier thoughts and feelings ahead in time.

Actually, when someone approaches a black hole, two things happen. One, your arms legs, and body would stretch like spaghetti, over 3 miles. No one could survive that, but if they did, if they had a microscope and looked back on Earth, they would see civilizations rise and fall and the evoulution of the human race. Time would be accelerated to something like 100 years per second! So time travel is kinda possible.
how do we know that? wouldnt we need to go up there and get nere a black whole with a telescope? And thats impossible, so how do we know?
*drools* mmmm! Truth!
Now imagine flying towards one of these objects, as light from the stars behind it becomes bent by its strong gravitational field, and circling around it at some distance. Now imagine approaching and orbiting at the photonsphere, the radius at which light rays become so bent, they actually curve all the way around, and you can see the back of your head! Think of falling deeper and deeper towards the black hole, as tidal forces stretch your body into spaghetti. Imagine spiralling inward toward a singularity in spacetime, an infinitely dense geometric point where all the laws of physics, in fact the very fabric of space and time, break down and cease to exist. Picture watching someone take the plummet towards the event horizon, the point past which no information can be transmitted, seeming never to quite reach it, though he himself feels he has already crossed it - in a finite amount of time!
