Because then matter and antimatter, which must have existed at that time (symmetry presupposed) in identical quantity, would have annihilated each other shortly after the big bang. This did not happen. Matter retained the upper hand. So we know that the universe cannot be symmetrical. But why? The physics supplies us to it – still – keone clues. Astrophysicists have therefore been ...
