How do we know that nothing can travel faster than the speed of light?
Is it true that nothing can travel faster than light? Or was that idea made up?
If light can't even escape a black hole, does that mean it is being sucked in faster than its speed? Why is the speed of light not infinite? Is light speed actually not the speed limit in the universe? If in theory an object reached the speed of light what would happen to it? 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? If light travels so fast, why is it so easy to stop? Will the speed of light ever change? Does light travel through space forever? What if time was passing a bit faster here on Earth? Why does everything with time slow down as one travels close to the speed of light? Since information cannot be transported faster then the speed of light, isn't Einstein's "spooky action at a distance" solution more correct then "quantum entanglement"? Has anyone ever accelerated something to the speed of light? Why does time seem to go faster as we age? Has the speed of light changed? 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? Why does time seem to go so much faster as we age? Can the speed of light be increased? Why can't black holes be used to accelerate bodies to the speed of light? Why does the time go so fast? Why is time slower down near heavy objects? Assuming the Many Worlds theory is correct, is there a universe in which the speed of light is different than our own? How would that change things? When light travels from one medium to another, its speed changes, why is this so? If a photon travels at the speed of light and time dilation at the speed of light is infinite, does this mean that, from the photon's perspective, it takes no time at all to cross the entire universe? If photons don't travel through time, why does it still take time for them to reach our eyes? How did Einstein conclude that speed of light is constant? Special Relativity: What would stop someone accelerating beyond the speed of light if they had achieved 99.9% of the speed of light? Why is time slower near heavy objects?
