Can there be a particle faster than light?
Can some particles travel faster than the speed of light?
What happens if you travel faster than the speed of light? Do galaxies travel faster than the speed of light? Do gravitational waves travel faster than the speed of light? How does light travel so fast? Quantum theory says a particle can be anywhere in the universe in the next instant.  Photons are the fastest particle but are limited to the speed of light. How can both be true? Is the speed of the amplitude of light faster than light? Is it true that if we will travel faster than the speed of light, we can go toour past? Can't light reach us quicker if it was emitted by something coming towards us at near the speed of light? Why does light travel so fast? Can you travel at the speed of light? Speed of Light: How fast can we move? Why do we assume that travelling faster than the speed of light necessitates time travel? Why does light travel so fast in space? Is it possible for humans to ever travel at (or near) the speed of light? How is phase velocity greater than the velocity of a particle? If an object could travel at the speed of light, what would happen to it? Is the speed of dark faster than the speed of light? How fast can you accelerate to the speed of light? What would happen if an object would reach the speed of light? What happens to an object if it reaches the speed of light? How will it be to travel at the speed of light? What would happen if we travel at the speed of light? When will we be able to travel at the speed of light? If in theory an object reached the speed of light what would happen to it? How fast do electrons move? 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? Can we increase the speed of light in a vacuum? Is the quantum entanglement effect faster than the speed of light? What happen if we moving with the speed of light? If you could travel the speed of light, what would happen?
