Cosmic acceleration and dark energy do not exist

PSI Blog 20211018 Cosmic acceleration and dark energy do not exist

 

Thanks to George Coyne for this heads-up:

 

 “Hi Glenn,

 

As you and I do not believe that the Universe is expanding, there was never the acceptance that the misconceived expansion was accelerating. Now there is a 2019 study debunking the acceleration.

 

Here is the paper: https://arxiv.org/pdf/1808.04597.pdf

 

It is also described in this Big Think article:

[GB: Note that the Nobel Prize was given to Saul Perlmutter, Brian Schmidt, and Adam Riess “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae”.[1] That was an ad hoc proposed as a solution to observed red shifts indicating galactic recession at velocities greater than c. The choice at that time was: 1) throw out Einstein’s light-speed limit for the universe or 2) find some data indicating the “early universe” expanded faster than the usual misuse of the Hubble constant allowed:

 

 

Astute readers know all this speculation is based on these erroneous assumptions:

1.  Light consists of massless particles.

2.  Light travels through perfectly empty space.

3.  Light displays perpetual motion.

4.  The cosmological redshift is a result of the Doppler Effect or of expanding empty space.

5.  Universal expansion is propelled by matterless motion otherwise known as dark energy.]
