Universe may have resulted out of a ‘Big Bounce’, says Italian physicist Carlo Rovelli

Dr. Rovelli has written several popular-science books. In his latest work, White Holes: Inside the Horizon, he explains the theoretical existence of white holes — the converse of black holes. The latter is believed to be the ultimate graveyard of all matter from which nothing, not even light, can escape. White holes on the other hand may beget a new universe. Though still in the realm of speculation, the math checks out
