Author's Wikipedia page: https://en.wikipedia.org/wiki/Eric_Lerner I get the impression he's regarded as something of a crank in astrophysics communities.
Crackpot stuff, unfortunately. The CMB and host of other stuff is evidence for a Big Bang. The merger stuff JWST has falsifed was never really on solid ground anyway but tuned cosmological simulations. The simulations probably got subgrid physics wrong (same issue as climate models face).
You may be right, but I think referring to this perspective as “Crackpot stuff” is entirely too strong a criticism. Wormholes and flying cars are “crackpot stuff.” But regarding this question it feels like you are reaching for the strongest possible language to rebut a position you simply disagree with. We really are in a moment where serious astronomers and astrophysicists are evaluating validity and correctness of…
Umm, wormholes maybe. Flying cars have existed for the better part of a century. The fact that nobody has successfully brought one to market yet means that you and I don't have them. But humanity certainly does.

Wouldn't be the first time something like that happened. We used to think mars had civilization and canals until not too long ago (kinda funny that the drawings of those canals ended up looking a lot like the veins in a human eye). Also, the idea of radio waves going through the ether, on which a lot of science was based got disproved at some point.
> We used to think mars had civilization and canals until not too long ago Who? I've never heard of such an idea.
This guy is a known crackpot. He's not a serious researcher and has no published papers in astrophysics. File under "horseshit".
according to wikipedia hes been funded by nasa. and also looks like youre incorrect about not being published
any theory that gets rid of dark matter is better than what we have now. the cosmological constant was one thing (turns out Einstein found the quantized minimum energy of empty space, before quantum mechanics). This dark matter folly is taking fudge factor to the extreme. it's lazy.
I have no idea if this is true or not. But for a moment I was just imagining a world where scientists agreed that the Big Bang never happened. How many physicists' work would be thrown in the trash? How many high school science books would have to be updated? How would the general public's trust in science change? Would be such an interesting thing to observe.

Definitely not ether, those foolish old scientists got the name wrong :D
> One paper’s title begins with the candid exclamation: “Panic!” Completely burying the full title "Panic! At the Disks: First Rest-frame Optical Observations of Galaxy Structure at z>3 with JWST in the SMACS 0723 Field" which is the best Panic! at the Disco pun I've seen in a long time.

sure i did. but what you say doesnt invalidate what i said. if someone finds this interesting they can pursue answers perhaps. personally i find it entertaining. also apparently this guys work has been published in a reputable journal
the point was that "the unpopular, unconvincing hypothesis is right" need be treated as a possibility only if the probability is high enough, and knowing that the vast majority are wrong is an important bayesian input in properly estimating that probability
Summary by a commenter in the link: Radio astronomy observations of Pulsars indicate that the Hubble Red Shift is caused by “Tired Light” rather than the expansion of the universe. When Hubble published his observations of red shifted light from distant objects there were two possible explanations that came to the fore. One, originated by Georges Lemaitre, was that the Universe was expanding. The other, from Fritz Zw…
"The component frequencies of each burst are delayed by different amounts of time depending on the wavelength. This delay is described by a value referred to as a dispersion measure (DM). This results in a received signal that sweeps rapidly down in frequency, as longer wavelengths are delayed more."
[https://en.wikipedia.org/wiki/Dispersion_(optics)#Pulsar_emi...]
"dispersion measure (DM) is the column density of free electrons (total electron content) — i.e. the number density of electrons (electrons/cm3) integrated along the path traveled by the photon from the pulsar to the Earth"
Now we have to worry about Big Cosmo?
