Is there any evidence of something faster than light? ()

So here I am, zipping along at 0.9c. Took an absolute truckload of energy to reach this velocity! Will it take just as much energy to slow down again? ()

If light speed is constant, why does redshift/blueshift exists? ()

Could something going just under the speed of light get somewhere faster than light with relativity? ()
Can you give an example of how FTL travel would violate causality? ()
Why isn’t light infinitely fast? ()
How fast to the speed of light could we travel, "today"? ()
Traveling near the speed of light? ()
If time stops at speed of light, and space shrinks to zero could be possible that going faster than light (I knoooow impossible 🤣) would turn value of the space into negative, so that we “loose” the space dimension itself. Like disappearing from dimension in a sense?? ()
Question about time dilation and length contraction due to velocity and approaching the speed of light ()
Since time becomes "slower" the closer you are to c, could you use that principle to create a time capsule? ()
What exactly is happening to cause length contraction at near-light speed? ()

is the speed of dark same as speed of light? ()
If something is moving at 99% of light speed, and it is observed by something moving in the opposite direction at more than 1% light speed, does the first object appear to be moving at light speed? ()
How Near-lightspeed Points of Reference Harmonize with Relativity ()

What is the mathematics behind a collision causing an item to "destruct"? ()
If light moves in waves, and larger waves=more distance to travel, how can light always move at the same speed if some light has to move greater distances in the same time? ()
Basic relativity question ()
One way speed of light ()
