assistant: Let's see...
I strongly disagree. Most of the red shift data shows a clearly
measurable expansion taking place. While this doesn't automatically
support a big bang, it certainly doesn't support steady state
whatsoever. The universe is definately expanding.
Fine by me. Whatever it is, it's worth studying. No comment on what it
best fits. It's highly unlikely to be reflected starlight, though, as if
it was it would be much hotter along the milky way, as there's more
stars there to heat it up.
Steady state has no prediction on element abundance, but the spread
certainly supports a form of origin similar to a big bang. If the
universe was steady state all the elements would have been converted to
iron with a few trace elements left over and unable to begin fusion.
Yep, I agree with this one.
It's been suggested that lower metallicity may account for the different
behaviour. I prefer the notion that the big bang is wrong and they are
normal in reality, but...
Yep. This is the same point as 4, 5, and nine, namely "the universe
seems to be older than the big bang theory can allow it to be".
Er... Don't understand.
Fudge factor to explain the real evidence of expansion rate. Einstein
had a similar fudge factor to this, and it was the greatest mistake of
his life etc. I'll see more evidence before I accept Dark Matter.
See "Older than predicted."
Strong anthromophic principle, "it obviously wasn't, though"
I agree it's an unlikely result though, and prefer the notion that the
big bang never happened, the matter/energy is constant and so it comes
as no surprise to find it consistent now.
