What was before the big bang? | Harald Lesch

How did our universe come into existence? Has it always existed or was there a beginning? And if so, what was before that beginning? Physicists like Albert Einstein and Georges Lemaître have been dealing with the origins of our universe for a long time. Harald Lesch shows us which theories have evolved over the past centuries and what the beginning of the universe as we know it could have been.
