So you are questioning his credentials, which you admit to have no knowledge of, but have no issue otherwise that negative parallax is a mystery to astronomy, as I provided reference in sources above?
I already provided a source which suggested several explanations, one was error but there are other explanations.
You actually think this is some big mystery secretly in astronomy and "they" are hushing it all up in case we discover their terrible secret that they don't know what they're doing?
Can we all agree that pretty much any viewpoint can be found somewhere on the internet?
Just scouring the internet to find someone who says something you agree with isn't helpful, it doesn't move the debate along at all.
The caveat to that is if the someone actually has some credentials which make their opinion worth considering.
Yes yes, I know, appeal to authority is a logical fallacy. Just because someone says something and the someone is an expert in a certain field it doesn't make them correct.
But expertise in a certain field gives them more credence than loonies shouting in corners of the internet.
Anyone can write a blog. Unless the person demonstrates some knowledge in the field they are talking about, has some qualifications or some professional experience then it's just someone shouting on a street corner. If that's the first source you came to then it's not giving much weight to your claim. And it's notable that your starting point in this discussion was "lack of parallax", something which would demonstrate distant stars, not close ones. I note you've failed to address that...
