(1) Since we don't have an actual theory of quantum space-time we cannot make any definitive statements about which predictions of any particular theory may or may not be valid. (2) You can have a beginning of our universe without an actual singularity. A singularity would imply a beginning but a beginning doesn't require a singularity. (3) The BGV theorem works for any universe expanding on average even for most theories of quantum gravity, (4) all the known theoretical and observational physics points to this universe having a beginning. Only speculative, non-verified, theories have any hope of avoiding a beginning. Such speculation is certainly not scientific at this point since science requires confirmation of theories.Michael G Strausshttps://www.blogger.com/profile/11580842374977938870noreply@blogger.comtag:blogger.com,1999:blog-1580378912972065231.post-65493340064032384712019-02-11T19:21:03.495-06:002019-02-11T19:21:03.495-06:00Hi there,

I have a question though about the beginning of the universe and the argument for creation. The following paper ( https://arxiv.org/abs/1705.00977 ) presents an argument that when we deal with a quantum space-time there will not be any singularities. I know the BGV-theorem says there will be in classical space-time, but doesn't this paper undercut their result? Ferinushttps://www.blogger.com/profile/07552551132983722994noreply@blogger.com
