The solution of Olbers' Paradox is:

- The universe is opaque at large scales
- The universe expands
- There is simply not enough starlight in the universe
- Matter is clustered in such a way that the integral brightness converges

• Cosmology -

The expanding universe is one way to explain Olbers' paradox. The most distance regions are highly red-shifted and do not deliver enough energy to make the night sky infinitely bright, when integrating to infinite distance.

• Cosmology -

There isn't enough starlight in the universe, as strange as that sounds. But redshift does dim stars that are moving away from us at near-c speeds.
