 Dear Participant
 of "Quantum Gravity and All of That" seminar series,

 This Thursday, May 13, 2021 at 17.00 CEST
 (08:00 Los Angeles, 11:00 New York, 18:00 Moscow, 00:00 Tokyo)
 we are pleased to have the talk by
 Prof. Roger Penrose (University of Oxford)
 "Why Resolving the Singularity Problem of General Relativity is Not
Just
 a Quantum Gravity Issue"

 Abstract:
 Over many years, there has been much impressive theorizing about how
 quantum mechanics might modify the space-time structure of general
 relativity at extremely tiny scales. A good deal of this work has been
 aimed at resolving the space-time singularity problem. However, there
 are strong reasons for believing that this cannot provide an overall
 resolution of that problem, the big bang having a totally different
 structure from the expected singularities in black holes.

 Conformal geometry provides a very different outlook, revealing issues
 deeply related to the 2nd law of thermodynamics and leading to an
exotic
 cosmological picture (conformal cyclic cosmology, or CCC), with various
 predictions, some now confirmed in observations of previously
unexpected
 effects--most particularly those referred to as "Hawking points".

 Here are the ZOOM coordinates:

 Meeting ID: 871 4996 5787
 Passcode: QgHolQie21

 We especially note that after the talk we will keep discussing giving
an
 opportunity to as many people as reasonable to participate.
 We do not impose any time limits for discussions.

 We are looking forward to welcoming you at the seminar.

 With very warm regards,
 the Organizers
