If the earth is flat and speeding up at 9.8 m/s the we should of reach the speed of light in less then a year. And if we have reach the speed of light then how are we still accelerating.
If there is no max speed then we dose light travel at the speed of light.
If we are going faster then the speed of light then how do we shine a flash light up.
if the speed of light is relative then why dose the speed of light relative to the earth not change if we are moving.
