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.]


[1] While I don’t agree with the theory, I believe Guth actually was among the first to propose it:

Guth, A.H., 1997, The Inflationary Universe: The Quest for a New Theory of Cosmic Origins, Basic Books

Guth, A.H., 1998, The Inflationary Universe: The Quest for a New Theory of Cosmic Origins, Basic Books, 384 p.

Guth, A.H., and Steinhardt, P.J., 1984, The inflationary universe: Scientific American, v. 250, no. 5, p. 116-128, 154.

[FAQ] Why can't people post comments on my blog?

The Blogger / Google login status, and the ability to post comments, is sensitive to both cookie and script filters. Your readers may need to enable (stop filtering) "third party cookies", in their browser and on their computer. The effects of the newly unavoidable CAPTCHA, and the Google "One account" login, requires third party cookies, even more than before.

Third party cookies filtering, in a browser setting, is the most common solution, overall - but your readers may have to search for other filter(s) that affect their use of Blogger / Google.

Any filters are subject to update, by the creator. If the problem started a few days ago, your readers may have to look on their computers, and find out what product or accessory was updated, a few days ago.
