When I said data, I mean something quantitative. This could be using JWST data directly, or other people's measurements. Citing papers is not the same thing as using data. They could have lifted measurements from these papers, and test how their model corresponds to observations. Like comparing...
I'm going to post something I wrote elsewhere. This addresses some of the discussion here, but I'm to lazy to completely rewrite it. Apologies for arriving late:
First thing to stress, the paper is not using standard cosmology. Secondly, if you open the paper you will see that it contains...
There is a link, but it's complicated. Observationally it is quite hard to find a correlation. On average galaxies forming stars rapidly have higher black hole accretion, it is thought this is due to both being driven by the gas supply in the galaxy. But it's very stochastic from galaxy to...
No, it's not the mainstream position. Who does Gupta cite when he makes this claim? No one. None of the papers in the following section say "as evolved", or anything like it. And does he do any analysis himself to prove galaxies are as evolved? No. It is a totally baseless claim. High redshift...
The idea isn't really so simple under the surface. The debate in this (sub)field is whether this inhomogeneous expansion (backreaction) exists even in theory. GR is sufficiently complicated that it can only be solved exactly in a few cases. In the standard treatment, one averages the...
Apologies for posting on an old thread, but you didn't get much of a response. I'm just going to quote a part to respond to multiple issues.
There are a few problems with this; a) LCDM doesn't predict galaxies on its own, and b) the galaxy measurements are not as robust as they appear.
LCDM...
