There are a lot of conclusions you can draw from the theory of special relativity that rule out FTL (faster than light) travel. The EEP states that the laws of physics operate exactly the same no matter where you are or how fast you’re moving. So a direct consequence is that the speed of light is the same, no matter where you are or how fast you’re moving. A minute later you’re going much faster, but the photon is still moving at the speed of light compared to you. In fact, no matter how fast you get going, light will always pass you at the speed of light.
