about cosmology. His white hole cosmology model in starlight and time is a non starter as a model from the get go.
I don't think people who got a PhD in Physics from LSU decades ago and then faded into obscurity as an engineer should be taken seriously on cosmology.
Note that he has ZERO experience in cosmology and general relativity as his dabblings attest to.
Again, I recommend you learn something about the SDSS survey, what those maps show and why they look like they do. Remember any survey like the SDSS is not a volume limited sample but a magnitude limited sample with the corresponding selection effects and observational biases that come with the territory.
