00:01The universe may have come from absolutely nothing, but physics says nothing is never truly empty.
00:10Imagine empty space like a restless ocean.
00:13Even without wind, tiny ripples still appear.
00:17Quantum space behaves exactly like that ocean.
00:20Energy pops in, then disappears instantly.
00:23This is called the quantum vacuum.
00:25Sometimes, a fluctuation becomes stable instead of vanishing, like a ripple freezing into a permanent wave.
00:32That state can rapidly expand into a universe.
00:36Another idea removes the beginning entirely.
00:39Time behaves like a smooth dimension, without edges.
00:42There is no first moment, only continuous geometry.
00:45But all models assume physics laws already exist.
00:49So, where did the laws of physics come from, before everything?
00:53Or, what if the universe never began?
00:56Next video explains.
00:57What do not need to know the buildings?
