why does light not lose any speed? How does it stay consistent over millions and millions of light years?
In: Physics
– Light has no mass
– Things that have 0 mass move at the max speed in the universe. Makes sense right? When you push on things to move them mass provides resistance. So something with 0 mass moves at the max speed.
– There has to be a max speed. Otherwise laws of physics break down. That max speed happens to be 299,792,458 meters / sec in our universe.
