Why can't a body move faster than the speed of light?
How do we know that nothing can travel faster than the speed of light?
Speed of Light: How fast can we move? Why is the speed of light not infinite? Is the speed of the amplitude of light faster than light? Why does light travel so fast? Is the speed of dark faster than the speed of light? What would happen if we travel at the speed of light? What happen if we moving with the speed of light? Why and how speed of light is not relative? (see details) Why does everything with time slow down as one travels close to the speed of light? Why does light travel so fast in space? We are travelling at light speed according to photons. But we shouldn't be able to reach the speed of light, so why does this happen? Is light speed actually not the speed limit in the universe? What’s the speed of light? If you could travel the speed of light, what would happen? What is the speed of light? What would happen if I travel with a speed of light? What happens to an object if it reaches the speed of light? Do gravitational waves travel faster than the speed of light? Is the speed limit of the universe really the speed of light? Why did Einstein assume that the maximum possible speed is the speed of light? What would happen if an object would reach the speed of light? If light can't even escape a black hole, does that mean it is being sucked in faster than its speed? If I could travel at the speed of light, what would I see? Will the speed of light ever change? How does time slow down when you travel near the speed of light? I think this is a very stupid question: in the reference frame of a photon, aren't we moving at the speed of light or faster? Do galaxies travel faster than the speed of light? Why is time slower near heavy objects? Why is time slower down near heavy objects? If an object could travel at the speed of light, what would happen to it?
