If lights is extremely fast and manages to get to the Sun to the Earth without getting darker. How come light can’t bounce off everything and manage to get into every crevice of Earth. Why are there shadows and why do they vary in shade? They should logically be the same shade right?
In: Physics
Because nothing reflects 100% of the light that hits it. Everything absorbs *some* amount of light, and that light gets scattered in every direction, meaning the next thing it hits is not as bright because there is less light hitting it *and it* absorbs some of it, and so on.
