Does light travel through space forever?
Does light travel indefinitely in space?
Is it possible for human to survive if they travel at the speed of light? When will we be able to travel at the speed of light? Can the speed of light be increased? Can you travel at the speed of light? Since the expansion of space redshifts photons (making them less energized) where does the energy go? Can a photon be at rest or does it have to travel at the speed of light? Is it possible to travel faster than light? If the universe is expanding when will it exceed the speed of light? What would happen if we travel at the speed of light? 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? Where does the energy from photons affected by the expansion of the universe go? How will it be to travel at the speed of light? What would happen if I travel with a speed of light? If space can expand faster than speed of light, then could a gravity wave travel faster than the speed of light as it's a ripple in space? Do galaxies travel faster than the speed of light? Is the universe expanding more than the speed of light? If yes then doesn't it break the cosmic limit? If I fire a laser beam into space, will it continue traveling until it reaches the edge of the universe? Could light be refracted into a loop, to be amplified or stored as a source of potential energy? The photon moves at the speed of light. In that case the mass of the moving photon is infinite according to Einstein's theory of relativity. Does that mean that photons warp space time infinitely? Is it possible to move at 98% the speed of light, then have the entire universe move the other direction at 5% the speed of light? Is it possible to increase or decrease the speed of light? If you could travel the speed of light, what would happen? Can we exceed speed of light practically? Can we theoretically make a compact artificial sun in space travel? Is it possible to travel Faster than speed of light? If photons don't travel through time, why does it still take time for them to reach our eyes? Does gravity affect light? Is expansion of universe faster than the speed of light? Can we see light? Do gravitational waves travel faster than the speed of light?
