His contention was that the red shift observed from Earth is not because the galaxies move but because the light photons lose their energy as they travel through space. The longer light travels the more energy it loses. His theory was mostly neglected as astronomers adopted the Big Bang as the consensus model of the universe. However, some astronomers became less certain of Big Bang when the James Webb Space Telescope came online. Seems like Zwicky is in for a new hearing.

The Big Bang may not have been the beginning of the universe.
At https://www.sciencealert.com/top-theory-on-moons-formation-might-have-no-evidence-after-all … the researchers are sceptical of the idea an asteroid the size of Mars zapped the Earth and spewed out a lot of material that later coalesced to form our Moon. There is a problem, however. A new analysis says there is absolutely no unambiguous evidence that such a giant impact ever took place. That is not to say an impact did not happen. It’s just that we can’t assume it did. The origins of our Moon is now up for further study.
Paolo Sossi argues the Earth and its Moon simply formed out of the same basic material and roughly at the same time. This removes the necessity for a hypothetical third body. The Earth and our Moon are too similar it would seem. Elements on Earth and the Moon have ratios of isotopes that are identical. Different forms of the same atoms with varying numbers of neutrons in their nuclei. No trace of an outsider has been found – as yet.
At https://www.thunderbolts.info/wp/2024/09/04/sunshots-4/ … Rens van der Sluijs asks, within mythology, when does a ‘sun’ specifically refer to our Sun – and when is it used as a metaphor for some other bright sky object. Some mythical stories appear to refer to suns that are not our Sun, the orb in the sky. They are often associated with sun shooting – arrows. Meteors or thunderbolts. Variants on the celestial archer can involve a sun or multiple suns. He goes on to describe some of the myths from around the world.
