Fraser Cain "Asks a Spaceman" Dr. Paul Matt Sutter – why do we call the Big Bang a singularity, when we also call black holes singularities?

The golden anniversary of blackhole singularity
Oct 01, 2015
When a star collapses forming a black hole, a spacetime singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that singularity with socalled ...
