Jovan sent in the link http://blogs.discovermagazine.com/d-brief/2018/03/20/stephen-hawking-fin… … what did Stephen Hawking's final paper say (and doesn't say). It was on the idea of the multi-verse – different universes within each other. This is bound up with another idea, eternal inflation. It continues to inflate forever – in most places. It can in some places actually stop – and where it stops a new universe forms (in a repeating process that has no end). You won't be much wiser after the reading the link.
However, a much more down to earth appraisal of Stephen Hawking is at www.thunderbolts.info/wp/2018/03/21/a-brief-history-of-unicorns/ … by David Drew (also known as the Soupdragon). He also has a web site – www.plasmacosmology.net
