...expanding--inflating majestically like an unimaginably gigantic balloon--a finding that prompted Albert Einstein to acknowledge and retract what he called "the greatest blunder of my life." Hubble did nothing less, in short, than invent the idea of the universe and then provide the first evidence for the Big Bang theory, which describes the birth and evolution of the universe. He discovered the cosmos, and in doing so founded the science of cosmology...
Only 70 years ago, the universe was found to be expanding, but now there is a model of how it began: the Big Bang. At the beginning, it is said, there was literally nothing ("the void" of Genesis), not even space. Then there came into being a tiny speck of superheated space that contained enough energy to create all the stars and galaxies that fill the sky-with enough left over to drive the expansion of the universe ever since...
There is something wrong, however, with this account of how the universe began. There is not nearly enough matter in the universe to match the predictions of the Big Bang, and our current list of the particles of matter is almost certainly incomplete. We need a more sophisticated view of what is meant by "empty space," which turns out not to be empty at all. There are also serious philosophical problems created by the Big Bang, which can be described but not explained. Worse, nobody has been able to reconcile quantum physics with the other great triumph of 20th century...
