Time Travel???

Question

is it possible to go back or forward in time?

also if you were to travel faster than the speed of light would time freeze or slow down? if someone were to try this would it work?

SEROUIS ANSWERS PLEASE

Answer 1

Einstein general theory...

Here is the skinny,

In theory if you traved anywhere near the speed of light in your vehicle time would remain constant. Earth time would also remain constant, relative to each point.

At that speed when you returned from you one year trip, you would be one year older and yet many years would have passed on earth.

The problems of navigation at this speed (hitting a rock), a vehicle that could move this fast, the g-force would instantly crush you. These things make it possible in theory but by know methods of today it can't be done in practice.

as far as getting back, this would require some sort of worm hole.
I won't even go there, as I would type all night.

The simple of you question is this. We all travel into the future every time we move (the amount is so minute it is not measurable). fixed objects move through time more slowly, relative to objects in motion.

Stein, explained it this way; consider a open boxcar on a train.
two people on the box car which is moving at 40 mph.
One person with a radar gun ahead up the tracks at a fixed point.
at the determined time when the box car passes the radar gun man he will take a reading one the baseball, suspended in air, thrown between the on the boxcar. They threw the ball at 40 mph.

the man at the fixed point will get a reading of 80mh on the ball, while it was in air thrown between the two on the car.

If you had another man on the car with them and also hit the ball in mid air with another gun the reading would be 40mph.

same ball, in same place, suspended in mid-air, yet radar guns both are correct, on reading 80mph the other reading 40mph.

Hope that helps.
P.s. The man that said 3- days in space is like 7 earth days has the righ idea. but his figures are way off. There is one case of a human (a russian) who stayed on a space station moving at a very high rate of speed for months, he travled less than 20 seconds into the future. he is the only time travler to date.

And yes this thoery has been proven. matching atmoic clocks that measured to the million parts per-second. one stayed on the groung the other was launched on the rocket and compared. this was repeated several times. the difference was the clock on the rocket was behind the one left on the ground.

So Ole Stein proved with no doubt that time is no "fixed" always moving constantly at a fixed rate. This changed math forever and basically discredited everything Newton ever wrote about math.
It won Stein the Nobel prize. The things I confusingly described are the basics of relativity.

So your question: is it possible to go back or forward in time?
POSSIBLE***** I suggest you look up and consider the word possible. The answer to possible is yes.

Answer 2

It is possible to go forward in time faster than the earthly rate, but not practical because you would need monstrous amounts of energy to accelerate to a significant fraction of the speed of light, and the same amount again to decelerate.

Faster than light particles, or tachyons, are only hypothetical at this time. They would go a long way towards explaining quantum entanglement, though.

Only electromagnetic radiation travels at the speed of light. Nothing with mass can ever get to light speed, ever, because that would result in its mass increasing to infinity and time and thickness shrinking to zero. All the energy in the universe could not accelerate one proton to light speed - so fuggedaboudit.

Faster than light travel is not physics but metaphysics, and belongs in the religion section if it belongs anywhere.

All the above statements are of course subject to change if anyone finds some data that disagrees with them, according to the way science operates.

By the way, relativity did not "destroy" Newtonian mechanics, which continues to be useful whenever a rocket is launched into space and steered in a desired direction - or whenever a gun is aimed at a target here on earth. Relativity is only a refinement of Newtonian mechanics, needed to correctly compute trajectories at very high velocities or in intense gravitational fields.

Answer 3

No, time travel is impossible. It is always moving forward at a constant rate.

There are theories that the closer you travel to the speed of light, the slower time moves. So 1 year for you, would be like 20 years for your friend. (This is just a theory, and is not time travel).

Objects can't travel faster than the speed of light. Einstein said that there is a barrier at the speed of light. Objects traveling slower than it, can't move faster than the speed of light. And objects traveling faster than the speed of light, can't travel slower.

I do remember something a bout a DeLorean traveling 88 mph though. (jk)

Answer 4

well i'm not too sure about time 'travel' but if u were to go the speed of light (faster than is physically impossible i think) well actually as you built up to the speed of light then time would slow down more and more and technically once the speed of light was reached time would freeze altogether... hope that makes sense. but I guess the 'real' answer is : no one knows for sure... its a thinker

Answer 5

Going foreward in time is somewhat possible. The People in the international space staion experince it. For example on earth; 1 week is the same everywhere. But in outer space the space staion goes around the world faster that a normal earth day. 3 space staion days equals 7 earth days, so if you stayed on the International Space sation for one month it would equal 70 earth days. Thus you go in time by a ratio of 3/7. : )
yes i know it is confusing.
