Subir Sarkar Questions Evidence for Dark Energy

Sabine Hossenfelder interviews Dr. Subir Sarkar of Oxford.

Summary of the Dr. Sarkar interview: His team has identified serious errors in the data science that found evidence for cosmic acceleration. Most of the interview is spent going through the various errors in data catalogues and statistical methods. Upon re-analysis, his team finds not evidence for acceleration, but instead a cosmic flow of spacetime in the same direction as the CMB dipole. Our galaxy is moving in the same direction as the dipole but 4x faster. Sarkar gives credit to Singer who found this prior but was discounted. He then moves on to a discussion of the flaws in the concordance model (CMB+SNe+BAO). Bottom line he says “Evidence for isotropic acceleration is non-existent, and it is this that has had a major impact not just on cosmology but also fundamental physics.” So essentially he is calling the concept of dark energy into question. He then goes on to discuss how data science errors are problematic in the calculations of the Hubble values discrepancy. Some supernovas with different redshifts in different catalogues and other problems.

Here are some articles and papers regarding Dr. Sarkar’s findings:

Sarkar also talks a lot about interpretations, or what I call narrative, and how the field gets locked into certain interpretations. Those interpretations or stories then take on a life of their own and are hard to change when there is new evidence or in this case errors in the data science. It is fascinating how physics and cosmology build up cognitive models or understanding based on stories which are not science themselves, but which are derived from the science. Dark energy, dark matter, one time inflationary big bang, expansion, acceleration of expansion, these are all various stories abstracted from the observations. And some stories are based on other stories, like a story arc of a fiction. It gets very difficult to unweave the tangled tale.

NPQG teaches that the universe is in a steady state configuration with new spacetime æther created intermittently when AGN SMBH jet Planck plasma. Thus galaxies are expanding in to each other, rather than the ΛCDM narrative of the universe expanding as a whole. It turns out that the NPQG narrative of galaxies expanding into each other is more logical and parsimonious and the effect on a photon is similar.
