so he introduced (which is perfectly reasonable) a *cosmological constant* ; after Lemaitre and Friedmann developed the Big Bang idea and Hubble showed that the universe is expanding, Einstein called the c.c. his greatest mistake. But it turns out a small positive cosmological constant seems to actually be true, and is the source of most of the energy in the universe -- and may well be responsible for
cyclic cosmology', so that a single big bang and cold dispersion to infinity could actually be false.
