Why isn’t space bright if sunlight is traveling through it everywhere?
I’ve always wondered about this. The Sun is constantly sending out light, and it’s only about 93 million miles away from Earth.
If sunlight is traveling through space all the time, why does space itself look completely dark?
I understand that objects like planets and spacecraft become visible when sunlight hits them, but why don’t we see the light traveling through the empty space between them?
I’d love to understand the physics behind this #space
