Re: Does it really matter ?
The Hubble telescope can now measure parallax out to 10,000 light years.
That has allowed the relationship of Cepheid variable rate to intensity to be confirmed, allowing the apparent intensity of Cepheids to be used to measure distances across the universe.
I'm reading up on H. Arp's stuff, but a first review has me thinking that some objects not fitting the Hubble law doesn't mean the Big Bang theory is disproved, only that we don't know the nature of some of the things we see. Claims that Einstein's General relativity is wrong have to deal with the detailed confirmations of it, at least near Earth.
