Yes and No.
Yes because traveling faster than light would make you go back in time.
No because you would need an infinite amount of energy to go at the speed of light according to Einstein Also going at the speed of light or faster you would tern into light. So "you" could not go at the speed of light but light could.
Time travel is possible but only at the earths gravitational pull (Turn) if the earth went backwards in spinning, but at the speed of light, the earth would move backwards through time as it broke the atmospheric compression field.
WELL, AS IT HAPPENS...
On a Distance against Time graph, the more distance you travel in the same amount of time, the steeper the line and therefore the faster your speed. The speed of light on such a graph is VERY steep, but it is NOT vertical. If it was a vertical line, then you would be travelling INFINITELY far distances in zero seconds. Which is impossible. However, assuming that it isn't, going EVEN FASTER would mean the line would start to curve back on itself, which would mean you were travelling a certain distance in a certain number of NEGATIVE seconds. Which would mean you were travelling back in time.
So to answer your question, going faster than the speed of light would result in a VERY high speed. However, to go back in time you would need to go faster than a vertical line on a distance against time graph. In other words, to go back in time you would need to go FASTER THAN AN INFINITE SPEED. So, no you couldn't travel back in time by going faster than the speed of light. Even if you could, which you can't.
Different Colors Of Light Travel At Different Speeds.
no
Cerenkov radiation is also spelled as Cherenkov is an electromagnetic radiation that comes for particles as they travel at speeds greater that the speed of light. The radiation if seen is often blue and is not harmful.
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
varying speeds different colors of light travel
Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.
it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.
Top speeds have ranged from hundreds of miles per hour to speeds far greater than the speed of light.
No, that is not true. In a vacuum, all electromagnetic waves travel at the same speed.
If you could travel faster than light, then you could also travel to the past. This is related to the definition of simultaneity, in the Special Theory of Relativity.If you could travel faster than light, then you could also travel to the past.

No. Just to travel AT the speed of light would require more energy than the entire universe contains. So all objects move at some fraction of light speed, never 1 nor greater.
no...but there are particles which have speeds closer to light,like photons,god particle(matter-wave)particle
