Facets of their theories. Predictions based on their ideas that do not bear out.
But in this specific case, Enyart made the prediction that the galaxies that the scientists were trying to observe in the HDF would turn out to be not much different than the galaxies we see locally (“They were normal” in his words). The HDF data has been available for nearly 2 decades now. Does the HDF data actually bear out Enyart’s claim?
Which is simply an argument from popularity.
It is the popular consensus in science, but that belief is based on the convergence of multiple lines of evidence. You are certainly welcome to dismiss it, right along with other arguments that are not seriously questioned in science – like the earth being round, or the earth circles the sun, or jumping off a cliff is not a good idea.
I don't know.
You said there were "high Z" objects out there. Aren't these light sources that are greatly red-shifted? Isn't red-shift correlated to distance?
As I suspected, your technical understanding of physics behind the Deep Field efforts is tenuous at best. Probably best that you simply come right out and admit that you are just rooting for what Enyart said, and not pretend to critique the concepts from a technical perspective. Enyart playing the part of the court jester is entertaining enough.
