Thanks for the thoughtful reply. Discussing this with you has made me think and research further too so we've both benefited from our discussion
here!
I looked at Arp's site and illustrations.
Let's start with his rebuttal here:
www.haltonarp.com...
He shows the NASA image that claimed there is no bridge.
Then he showed a manipulated photo showing a bridge, so he claims.
I tried what he said and downloaded the highest resolution image available here:
hubblesite.org...
Here are the 3 photos:
Nasa photo from Arp's site:
Arp's manipulation of that photo:
My manipulation of the highest resolution photo I could find (from
hubblesite.org... )
If you want to call that a bridge like Dr Arp insists it is, then feel free. It looks to me like an optical artifact as a result of photographing 2
bright objects so close together. And I'm not the only one who thinks so, as Dr Arp points out:
Personally I can say that after more than 30 years of evidence disputed by widely publicized opinions that the bridge was false, I was saddened
that not one prominent professional has now come forward to attest that it is, in fact, real.
One might argue that prominent professionals might have something to lose by admitting it's real and that's why they don't, but I'm not a
prominent professional and in my independent opinion, the prominent professionals are right on this one, there's no bridge here.
We have to look at specific cases and claims of bridges to evaluate them. Unlike the other bridge referenced here:
www.astr.ua.edu... which may just be a coincidence, this one isn't even a coincidence, there is no bridge but of course
everyone needs to form their own opinion.
I also looked at Dr Arp's illustrations where I also see no bridges:
The sky is a big place with 100 billion galaxies and lots of objects that are different distances away can appear close to each other from our
perspective, but that doesn't mean that they are close to wach other. This should be obvious and especially with no bridge, the argument is not very
credible without further proof.
Lastly I have one more point to make, going slightly off topic for an analogy. Quantum mechanics is extremely bizarre and the predictions from it are
very non-intuitive and sometimes even mind-boggling. It seems like an inelegant theory and may not even be right in the sense that Newton's ideas
about gravity weren't precisely right, but like Newton's theories, quantum mechanics does a great though not perfect job of predicting the
observational evidence so that's why it's accepted whether it's right or not.
I suspect some part of the cosmological theory is wrong now, like the modern version of Phlogiston. But until someone comes up with a theory that
explains the observational evidence better than current theories, the current theories will continue to be used. In the case of Phlogiston, somebody
found that when magnesium burns it gets heavier which tanked the phlogiston theory. Some people seem to think these bridges are the "magnesium" that
will tank the redshift theories, but Dr Arp's claim that the NASA photo shows a bridge doesn't hold up under scrutiny. So I don't think we've
found the "magnesium" yet.
But I do have a gut feel our current theories have major problems, we just need somebody to provide credible evidence of this and provide a theory
with better predictions of the observational evidence. So far Dr Arp has failed to do that, and nobody else has succeeded yet either. But that
doesn't mean it won't happen, I suspect a breakthrough may happen in the future. After all something has to be done about this dark matter and dark
energy nonsense, right?
