It’s like an Evolution: we live here, because only we can live here
This is the brief history of time. Showing Y — axis as density of matter as the universe is expanding and X — axis as the age of the universe, and it looks like energy density is constant as the universe is getting bigger. And we are living in a time where energy density of empty space is three time bigger than energy density of matter. This is the only time in the entire history of universe when this two lines intersects, we are living in a very special time.
