We FINALLY Know What Happened Before the Big Bang

We FINALLY Know What Happened Before the Big Bang The universe is 13.8 billion years old — but what came before that? This video follows the clues from the cosmic microwave background to inflation, and shows why the answer may be hiding inside black holes. We cover the information paradox, real evidence from the Event Horizon Telescope and LIGO, and the strangest idea yet: Planck stars — objects that never collapse into a true singularity, but "bounce," echoing the Big Bang in reverse. #BigBang #BlackHoles #Physics #Space
