why does light not lose any speed? How does it stay consistent over millions and millions of light years?
In: Physics
The closest analogy I can think of that would help at the 5 year old level is that this question is like asking why water is still wet after millions of years. Moving at the speed of light is just a natural part of light, even moreso than water being wet. Water can change to ice, and light can change wavelengths, but the light will still be moving at the same speed.
