| Starry Night - VAN GOGH |
A very starry night, a grandfather and grandson were watching the sky.
- You know you're not seeing stars as they are, but as they were?
said the old man.
The child stared at him, do not understand ...
And that being the distance from Earth to the stars so big, but light travels at 300,000 km / s, it takes a while to get to us. For this reason, it is possible that some of the stars we see no longer exist: what we actually see is the light emitted and still traveling through space.
