was a vacuum energy (the energy of empty space) that kept gravity from
pulling the universe in on itself, ... A problem with the
cosmological constant is that it is constant, with the same

however, had to be negligible in the universe's earliest stages;
otherwise the galaxies and all their stars would never have formed.".
