Laser links would make everything more complicated and expensive. Radio antennas can share the same hardware to link with many terminals, not so with laser systems. They are point to point, so you need many more. They also require precise p

It's just nowhere near feasible. Each element would need power, orientation, precise positioning and a data link to the processing stations. For SKA low the raw data rate from all antennas is something like 2 Pb/s. Which is more t

That's not the case. The hydrodynamical simulations mentioned use the same cosmological value set by CMB data. The ratio is not the same in every galaxy, because matter and DM behave differently on small scales, but this variation come

Many state of the art galaxy formation simulations use MHD, it does not however affect the formation of the Cosmic Web. > MOND’s also been around since the early 1980s, but, in 2021, it finally developed a model – the Aether-Scalar-Tenso

One can do simple simulations on a laptop which show the cosmic web. It's not really an excuse for not having tried. There are lots of claims in the article which need to be justified, and in science that comes before making big claims

>Cold Dark Matter, as used in simulations etc, usually has six free parameters. That is not correct. LCDM as a cosmology is described by 6 parameters mostly for CMB analyses, but this is much more than just CDM. These parameters include

Your suggestion about carbon is not falsifiable observationally. With real data you can only place an observational upper limit, you cannot measure the abundance is exactly zero. Without a quantitative calculated prediction of the carbon ab

Let me start by saying there are a lot of false claims in the dark matter section. It's also filled with self contradiction, announcing that DM as wrong, and later pronouncing LCDM as unfalsifiable. The pillars of modem cosmology are t
