The more of this thread I read, the more it becomes clear
to me that people are arguing from different sets of assumptions.
Scientific cosmology is still in its golden age, as I see it, because
of the wealth of new data that continues to pour into the field, and
because the field is beginning to merge with particle physics in a
way that complements both fields.

Because of this, "Big Bang cosmology" is really a collection
of competing theories that share as a basic principle the early
compressed universe and subsequent expansion. This part of these
theories has considerable evidence in its favor, although there are
loose ends to be tied up, no doubt.

Current hypotheses are more speculative, to be sure, and
have varying degrees of connection to observations, and some make
speculations the are currently untestable. But this is no reason
to ignore those basic aspects that have been tested.

Nothing exists without an underlying set of assumptions
which are untestable. But to continually draw attention to that
fact is boring, leads nowhere, and ignores important differences
between opposing viewpoints.
