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. they were closer together then. B. the universe has always looked as the some. C. their light takes so long to reach us. D. they have travelled such a long way. [单项选择]对于同个遍地产投资方案,某动态投资回收期(Pb)与静态投资回收期(Pb')之间的关系是()。
