Big fan of Lawrence Lawrence M. Krauss.
An excellent talk on the idea of a Universe from nothing, and how that is consistent with the current understanding of inflation and cosmology more generally.
Great ending too. Well, of the talk anyway, not necessarily the Universe in 2 trillion+ years — hahaha… ahhh.
Anyway, it’s not actually a pessimistic view, as the current model of inflation says that it is always happening somewhere* (here, ‘where’ does not refer to space in our Universe), and so there’s always the potential for a stable universe to ‘big bang’ itself out of nothing for a time.
