Question

Help answer this question below.

If you travel faster than the speed of light, Wouldn't you only be moving faster than photons rather than traveling through time? How does moving faster than a light photon constitute time travel?

    Relativity says that if you travel fast relative to someone, they see your clock as slowing down. If you take the same math which is experimentally shown to work below the speed of light, and extrapolate it to above the speed of light, your clock, as they see it, starts to go backwards i.e. you are traveling through time. It is all due to the fact that relativity says that space and time are not independent, but tangled up: movement in space affects movement in time. It also says that you can never reach, let alone exceeed, the sped of light.

    im alec is right. travelling faster than the speed of light gives a negative time when considering the maths. i think it is interesting that if someone was travelling faster than light directly towards you, they would overtake the light that they reflected at their starting point and you would see them start close to you and appear to move backwards as the light reaches you. This is just one of the many complications arising from possible time travel.

    There are 2 ways to answer this question:

    1. Going pass the speed of light and becoming infinat mass is like taking cookies out of an empty cookie jar. In other words it isn't possible (at least to our scientific knowledg).

    2. The variables of time and space are on a globe like grid. When you travel you give off complex cordinates in the direction you travel with the time variable changing all other variables in the complex globe like grid to where they are suppose to be. In other words
    Time=T Space=V Speed=S
    (T*S) squared by 2 = V relativity
    relativity is T squared + S*T+T
    ((T*S squared by 2) (S*T+T) = V

    The equation explains that time is not in a straight line and all things visible to are eyes is the outer properties of time which makes time and space non congruent with eachother. So only S and V are on a seperate track than T. Although that is only what we see not what is reality.

    The amazing advice of the one and only truthful,

    The definition of time itself loses its meaning as soon as you hit the speed of light or fall into a black hole.

    to travel means to go from point A, at time A, to point B at time B.

    if you travel faster than c, then there's some other reference frame in which event B precedes event A. in other words, somebody would observe you traveling backwards from B to A.
