So why does traveling faster than the speed if light send you back in time?
Relativity is the reason why, as an object with mass aprroaches the speed of light time slows down for thats mass whilst everything thing around it speeds up through time. When an object then reaches the speed of light it no longer is subject to time, surpassing the speed of light then allows that object to go back. In simpler words approaching the speed of light would take you to the future, passing it would take you back. Moving at different speeds affects the rate of change of an object.So why does traveling faster than the speed if light send you back in time?
There's a problem with using relativity for predicting how to travel back in time. The equation for time dilation is:Relativity is the reason why, as an object with mass aprroaches the speed of light time slows down for thats mass whilst everything thing around it speeds up through time. When an object then reaches the speed of light it no longer is subject to time, surpassing the speed of light then allows that object to go back.

The idea of traveling back in time by surpassing the speed of light is one idea, and the reason why it was proposed is because of how time changes when approaching high speeds. Thanks for clearing the reasons why it may or not be wrong.There's a problem with using relativity for predicting how to travel back in time.

t = t0 / √(1 - (v/c)²)
However, when v > c, t becomes imaginary. We don't have a definition for imaginary or complex time, so this simply means that the equations of relativity are not valid outside the range of velocities 0 < v < c.
It was once thought that supersonic flight was impossible for the exact same reason. The drag on an aircraft in the transonic region is also proportional to 1 / √(1 - (v/a)²), where a is the speed of sound.
There's a little more to it than that. Suppose a supersonic jet flies past playing music. You would hear it in reverse. People have supposed that the same would happen with light. And since the standard model says that the electromagnetic force is mediated by photons, one could assume that such forces would also happen in reverse. I'm curious about the strong, weak, & gravitational forces though. Even so, the equations we have are insufficient. Relativity is a century old. I'd be interested in hearing your views on this.

It would be even more interesting if it were true.I did not know that.That is interesting.
