Why and how speed of light is not relative? (see details) Has the speed of light changed? Is it possible to measure speed of light using lens? What is the speed of light in water? How is the speed of light different in glass and water? Is there a formula for calculating how much time would pass for me if I travelled at X percent the speed of light for X amount of time? Why is the speed of light not infinite? How did physicists arrive at the speed of light and verify that it is correct? Can the speed of light be increased? How did Einstein conclude that speed of light is constant? How does the speed of light in glass change? Is the speed of electricity a synonym for the speed of light? Why did Einstein assume that the maximum possible speed is the speed of light? How could "Albert Abraham Michelson" and "Edward Morley" have proceeded, having known the invariance of the speed of light C? What is the speed of light in a vacuum dependent on? Is the speed of the amplitude of light faster than light? If in theory an object reached the speed of light what would happen to it? How is the electricity speed measured? What would happen if the speed of light was 0? How do you measure the units of speed? What would happen if the speed of light doubled? Is light speed actually not the speed limit in the universe? Will the speed of light ever change? How fast can you accelerate to the speed of light? What is 'c' (Speed of Light)? How do you prove that light’s speed is independent of the reference frame? Why does the speed of light vary between different mediums?
