Can you time travel if you go faster than the speed of light?
Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.
What would happen to time if you moved at the speed of light?
The person traveling at the speed of light would experience a slowing of time. For that person, time would move slower than for someone who is not moving. Also, their field of vision would change drastically. The world would appear through a tunnel-shaped window in front of the aircraft in which they are traveling.
How fast is 99 light speed?
Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.
Is 99\% light speed possible?
Albert Einstein’s special theory of relativity states that photons—or particles of light—travel at a constant speed of 670,616,629 miles per hour. As far as we know, nothing can travel faster than this. But across the universe, particles are often accelerated to 99.99 percent the speed of light.
How long would it take to travel a light year at 99\% the speed of light?
In fact, if the traveler was going at 99\% the speed of light (a supposed trip of just over a year), according to him, his trip would only take 52 days to complete! These concepts of time dilation and special relativity are especially interesting to ponder.
Is a tennis ball moving at the speed of light?
On the other hand, if it were moving at the speed of light relative to you, then it was moving at the same speed as me relative to you, thus both myself and the tennis ball will hit you simultaneously. If this is the case, however, then the tennis ball would have been moving at a speed of 0 m/s with respect to me.
Why can’t light travel faster than the speed of light?
Because the light travel times resulting from the finite speed of light have not been taken into account.
What is the speed of the ball with respect to me?
In particular, the speed of the ball with respect to me will be less than the sum of your speed and 5 m/s. At low speeds this effect is not noticeable (speeds are additive to very close approximation), but at speeds close to the speed of light the effect becomes very pronounced.
What happens if you race at the speed of light?
In particular, if you are on a straight race track, and traveling at the speed of light, the race track will be compressed to zero length so that the starting line and the finishing line will be on top of each other. The race will be over as soon as it begins.
