| Evolutionary theories. The Belgian
George Lemaitre proposed the idea that about 20,000 million years ago all the
matter in the universe--enough, he estimated, to make up a hundred thousand
million galaxies--was all concentrated in one small mass, which he called the
"primeval atom". This primeval atom exploded for some reasons, sending its
matter out in all directions, and as the expansion slowed down, a steady state
resulted, at which time the galaxies formed. Something then upset the balance
and the universe started expanding again, and this is the state in which the
universe is now. There are variations on this theory: it may be that there was
no steady state. However, basically, evolutionary theories take it that the
