prove it happened a billion years ago first
all you have is a theory, not a fact
You cant even account for the light from that star to the earth being a pinpoint of light as it is, after travelling that far, over that time period, how does it stay so focused and pinpoint? and not diffuse over matter?
If I understand you correctly, you are of the "6000 year school". I'm not necessarily opposed to that if that figure is plotted against the "relativity" that would have slowed time down in the overall gravitational field of the universe from Day 1 to Day 6. In this sense, both scenarios work for me.
Though that the universe had this expansion would have provided the billions of years necessary to fuse the heavier elements through earlier generations of stars.
It appears to me that this is how God willed it. If you have a better theory as to how this came to be, I'm all screen.
Insofar as starlight is concerned, consider the Sirius system. This lies close enough to our solar system for the to be measured by 'triangulation' from one side of the Sun to the other, which gives us a "standard candle" relating to the cosmic distance scale. Knowing this luminosity, we can plot the distance to a similar star that may be some further distance out which is not subject to triangulation. Some of the light is scattered, but in such a sense to long be invisible to us over such distance scales. What we do see though is the source as a "pinpoint", at least insofar as it's close enough to see, mainly stars in our own galaxy. Though through Hubble and other orbiting telescopes, we can see galaxies very far away, yet recognize stellar sources therein as if they were just a few hundred lightyears.
As I asked though: Anything better?
