| Evolutionary theories. The Belgian
George Lemaitre proposed the idea that about 20000 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
universe was formed in one place at one point in time and has been expanding
ever since. Will the universe co A. during a pause in the expansion of the universe. B. at the time of the primeval explosion. C. and will continue to form for ever. D. about 20,000 million years ago. [多项选择]工作流程组织图应视需要逐层细化，如投资控制工作流程可细化为( )。
