Vacuum Friction and Hubble Redshift

"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-spacetime-slippery-superfluid.html

Nature: "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/superfluid-spacetime-points-to-unification-of-physics-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."

Photons are slowed down by vacuum friction – is this the cause of the Hubble redshift, in a STATIC universe? In Einstein's schizophrenic world "slowed light" is never associated with the Hubble redshift. The discussion always goes to a red herring – loop quantum gravity and "energy-dependent speed of light":

Sabine Hossenfelder: "It's an old story: Quantum fluctuations of space-time might change the travel-time of light. Light of higher frequencies would be a little faster than that of lower frequencies. Or slower, depending on the sign of an unknown constant. Either way, the spectral colors of light would run apart, or 'disperse' as they say if they don't want you to understand what they say. Such quantum gravitational effects are miniscule, but added up over long distances they can become observable. Gamma ray bursts are therefore ideal to search for evidence of such an energy-dependent speed of light." http://backreaction.blogspot.fr/2017/01/what-burst-fresh-attempt-to-see-space.html

Any thought transition from "slowed light" to "Hubble redshift" is prevented by crimestop:

"Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." http://ebooks.adelaide.edu.au/o/orwell/george/o79n/chapter2.9.html

On August 15, 2017 Sabine Hossenfelder exposed the expanding universe (Big Bang) theory as one of the silliest concepts in the history of science (the discussion with "Ambi Valent" revealed the idiotic implications of "expanding space between non-expanding galaxies"):

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." http://backreaction.blogspot.bg/2017/08/you-dont-expand-just-because-universe.html

Cosmologists will practice crimestop for some more time but then the STATIC universe theory will be restored and universally accepted - this is unavoidable.

"Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction.

Bingo the Einsteiniano is puzzled:

Ethan Siegel: "The Greatest Cosmic Puzzle: Astronomers Find Stars That Appear Older Than The Universe [...] The oldest stars we've found in the Universe are nearly pristine, where almost 100% of what makes them up is the hydrogen and helium left over from the Big Bang. They come in at over 13 billion years old, with the oldest at 14.5 billion. And this is a big problem, because the Universe itself is only 13.8 billion years old. [...] It's also possible that we've got the age of the Universe wrong! The way we arrive at that figure is from precision measurements of the Universe on the largest scales." https://www.forbes.com/sites/startswithabang/2017/09/07/the-greatest-cosmic-puzzle-astronomers-find-stars-that-appear-older-than-the-universe/

No "precision measurements" are possible, Bingo, if the theoretical framework involves, on the one hand, the idiocy "expanding space between non-expanding galaxies", and, on the other, the fudge factors dark energy and dark matter.

The Universe is not expanding – it is STATIC. 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).

We've been fans of astrophysicist Ethan Siegel for a while. That's because he has consistently crafted outstanding content that's smart and skeptical. At his blog, Starts With a Bang!, Siegel explains the intricacies of the Universe on a daily basis, distilling mind-numbing notions into palatable and entertaining forms. In every article, Siegel leads readers on a journey. Each time, we follow along with rapt attention, ending a little more enlightened than we were before. http://www.realclearscience.com/blog/2016/11/14/the_top_10_websites_for_science_in_2016.html
