   JWST's surprising galaxies and Big G   
   20 Aug 23 21:38:36   
   
   From: holobhdu@gmail.com   
      
   The James Webb Space Telescope (JWST) has been revealing   
   a large number of very high red shift galaxies which are unusually   
   massive and bright for their age (several hundred million years   
   after the big bang).  This is a contradiction of today=E2=80=99s mainstream   
   cosmology, which says they can=E2=80=99t have had nearly enough time   
   and efficiency to grow that many stars so fast.  Some possible   
   explanations have arisen but with no compelling support yet.   
      
   A naive suggestion: Would a somewhat larger value in big G   
   in very early times help explain this unexpected efficiency?   
      
   I do know that many if not all searches for cosmic change in the   
   value of G have turned up essentially null, or at best, mixed   
   results so far.  But could the JWST results be a small hint?
