Hi Snowflake,read your post with much interest,and concurr with much
you say,but not all.Paul Dirac was concerned much with how we
observe time,and by default,how we evaluate such things such as the
expansion of the universe and its age.You mention gravity frequently,
but do not seem to observe or comment on how gravity can effect
the time frame of the observer,and therefore influence the opinion
of the observer.Time is a variable,determined by the gravitational
environment the observer is in.My point Snowflake,is that the idea of
a uniform expansion of spacetime does not include the influence of
gravity,and it's local and none local effect on time.
Am not in contest with you Snowflake,find your post very interesting,
just responding to the points you have raised.
