The universe is not expanding - it is STATIC. Some expansion occurred in the unscientific cosmological models but recently Sabine Hossenfelder mercilessly stopped it and now there is no expansion at all:
Sabine Hossenfelder: "The solution of general relativity that describes the expanding universe is a solution on average; it is good only on very large distances. But the solutions that describe galaxies are different - and just don't expand. It's not that galaxies expand unnoticeably, they just don't. The full solution, then, is both stitched together: Expanding space between non-expanding galaxies." https://www.forbes.com/sites/startsw...ding-universe/ "Expanding space between non-expanding galaxies" is a downright idiocy - it exposes the expanding universe as one of the silliest concepts in the history of science. The idiocy cannot be fixed or camouflaged - cosmologists can only join Max Tegmark and become experts on psychology, artificial intelligence, etc. Then why do photons redshift? Star light slows down as it travels through the space vacuum, an effect caused by a factor equivalent to vacuum friction.. For not so distant stars this is expressed as Hubble redshift but beyond a certain distance the star light does not reach us at all (Olbers' paradox): "This leads to the prediction of vacuum friction: The quantum vacuum can act in a manner reminiscent of a viscous fluid." http://philpapers.org/rec/DAVQVN "...explains Liberati. "If spacetime is a kind of fluid, then we must also take into account its viscosity and other dissipative effects, which had never been considered in detail". Liberati and Maccione catalogued these effects and showed that viscosity tends to rapidly dissipate photons and other particles along their path, "And yet we can see photons travelling from astrophysical objects located millions of light years away!" he continues. "If spacetime is a fluid, then according to our calculations it must necessarily be a superfluid. This means that its viscosity value is extremely low, close to zero"." https://phys.org/news/2014-04-liquid...uperfluid.html Natu "As waves travel through a medium, they lose energy over time. This dampening effect would also happen to photons traveling through spacetime, the researchers found." http://www.nature.com/news/superflui...hysics-1.15437 "Some physicists, however, suggest that there might be one other cosmic factor that could influence the speed of light: quantum vacuum fluctuation. This theory holds that so-called empty spaces in the Universe aren't actually empty - they're teeming with particles that are just constantly changing from existent to non-existent states. Quantum fluctuations, therefore, could slow down the speed of light." https://www.sciencealert.com/how-muc...s&limitstart=1 Pentcho Valev |
