Due to relativity, if you accelerate from rest to faster than light speed would you meet yourself coming back?

Question

Einstein proposed that time was relative and at Velocities of greater than C (the speed of light in a vacuum) that time runs in reverse. Therefore if you accelerated on a linear trajectory, time would increment until your velocity reached C. then at speed greater than C time would decrease but your postitional vector would continue to increment. does this mean that you are in two places at the same time? as your linear position continues to increment but the time taken for you to achieve this position is reduced so in theory you are at two different positions at the same time? relativity ..... the more you think about it the harder it gets

Answer 1

Your understanding of relativity is wrong.

You cannot even accelerate to the speed of light, let alone beyond it. Relativity predicts that infinite enrgy would be required to accelerate a mass to the speed of light. IT makes no predictions that would make travel backwards in time possible.

Answer 2

If it were possible, depending on how much faster than light, and for how long you travelled, then you might just see yourself for long enough before you started to accelerate - depending on how far back in time you went.

A good example of this is the 'Picard Manouvre' used by captain picard on Star Trek, the next generation. He briefly went to warp speed so as to appear in two places at the same time in order to confuse an enemy vessel.

Unfortunately we don't have the technology to stop you being splattered against the nearest wall, even if we could accelerate fast enough to reach those speeds. Although, theoretically if the ship survived and continued faster than light, then as it travelled back through time, you would be unsplattered from the wall, but as time was moving backwards you would be unaware that it had just happened - and the ship would not be travelling at that speed then, because it was only when you started accellerating that you were splattered, so i think this is so paradoxical that we can assume that it wouldn't work too well.

Answer 3

einstein also proved that an object cannot reach a higher velocity than C. any attempt would result in the energy used being converted into mass and so the question is pointless.

but in theory, if you set off at a linear trajectory, you would never be in the same point in space as when you started off. however, some scientists have theorised that if you traversed at a linear trajectory you would infact reach the same destinationas they say space is curved. but they cannot prove all that **** so it is just all bullshit and make believe.

Answer 4

Einstein said this. It is sad so many high I Q people believe him. If time was reversible at one time in future mankind would know how to make use of this property of time.

If this was the case we should be meeting our descendants who come over to see how we in backward 21st century live.

Relativity theories are simply mathematical and make people foolish enough to believe them look clever.

I have done Laplace transformations. Some mathematical expressions which cannot be resolved in time can be taken to an imaginary domain called "s" manipulated and brought back into time. Then a solution in time is found. Though these things obey mathematics, we must question those very laws of math.

Answer 5

As an object approaches the speed of light the equations of relativity show that the progression of time for that object slows-reaching a stop at light speed. When we try to use the equations for an object travelling faster than light the time turns out to be complex as in the mathematical notion of complex numbers a+bi where i is the root of -1. Hence relativity says nothing about time as we understand it for an object travelling faster than light.

Answer 6

I thought Einstein's theory only concerned velocities "of the same order as C" (sort of C/2 etc) and not greater than C. Anyway, even if the latter are concerned, they're not attainable so don't worry. But in thoery, your suggestion seems right.

Answer 7

This is a popular misunderstanding created by the limerick

There was a young lady called Bright
Who could travel faster than light
She set out one day
In a relativity way
And came back the previous night.

Which is amusing but poor science.

Answer 8

The maximum speed that even a particle can attain is always less than the speed of light.

Answer 9

he also proposed that traveling faster that the speed of light is impossible..... and time slows for the person or object that is traveling at near light speeds so in theory no.

Answer 10

Theoretically, you would.

But Einstein was wrong about several things, and the ability to travel faster than light is perceived to be one such thing.

So the point is moot.
