Because when moving at the speed of light, time stops for you and you can no longer measure speed (distance covered in a certain time).
vss sensor
The instantaneous velocity at the maximum height is zero because the object momentarily stops moving before falling back down due to gravity.
When you turn off a light bulb, the flow of electricity stops and the filament stops emitting light. As a result, the light bulb darkens and the space becomes darker.
Traveling at the speed of light, it would take approximately 4.3 years to reach Earth's nearest star, Proxima Centauri, which is about 4.24 light-years away from us. This means that reaching the star would take around 4.3 years from our perspective on Earth.
It would be if it wasn't for the fact that time relative the object moving at high speed slows down as you approached the speed of light, and completely stops when you reach it. This is what prevents things from going faster than the speed of light.
You need to know the Einsteins equation of relativity. t'=t(1-v2/c2)0.5 Basically this says the time (t') is relative to velocity (v). And C is the speed of light If v=c you get: t'=t(1-1)0.5=tx0 Therefore time stops for you when you reach the speed of light.
Even at modest %'s of the speed of light objects start to radiate their energy away in Gravitational Waves. So it is very expensive to approach the speed of light when most of your effort is just radiated away.
97mph is when the speed regulater stops you.
It will depend on your speed plus comfort stops, refreshment stops, refuelling stops.
No one can tell. Our current understanding of physics and how the universe works pretty much stops at light speed. So what would actually happen if you managed to perform the impossible - go faster than light - no one can tell.
Time for the object or person in question stops. This does not affect the objects around which aren't travelling at that speed or the region of spacetime which is around them. A simple and possible explanation is that time is stopped for the photon, but this stays unnoticed because we are not moving at that speed and so we cannot say what is happening to the photon.
