Abstract
The great filter is whatever obstacles prevent simple dead matter from evolving into a civilization big and visible on astronomical scales. The fact that we see nothing big and visible in a huge universe says this filter must be large, and a key question is the size of the future filter: how much have we passed and how much remains ahead of us?
