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?
