Why can't anything travel 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? 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? Why does light travel so fast in space? 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 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 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? Special Relativity: What would stop someone accelerating beyond the speed of light if they had achieved 99.9% of the speed of light? How much time passes for someone traveling at light speed for 20,000 light years? If in theory an object reached the speed of light what would happen to it? Can the speed of light be increased? What is the speed of light through different media? How can you make time appear to go faster? Why does time seem to go faster as we age? How can I make time go by faster?
