Subject: Dark Energy might not exist after all

A new paper challenges the reasoning behind why dark energy was proposed in the first place.

As an aside, Brian Schmidt won his Nobel for proving that the universe is expanding, exactly what this paper is questioning. Be a bit embarrassing having a Nobel for being wrong :)

Yeah, I know. But imagine if they gave out prizes for being wrong, you’d be rolling in it.

> Correction to what I say at 5:26 mins: The supernovae that Permutter & Riess used were not all from the same direction of the sky, but the low-redshift ones were in one direction, while the high-redshift ones were in the other direction. So, same problem (skewed sample), same conclusion.

Planck satellite results confirm that the universe is isotropic, so the direction doesn’t matter.
… unless …
Unless there is gravitational lensing by dark matter between us and the supernovae. Such gravitational lensing effects are negligible for nearby – low-redshift supernovae, so it doesn’t matter at all whether these are from a single direction or not. The only concern is whether there’s any gravitational lensing in the direction of the more distant supernovae.

> 740 supernovae from the GLA catalogue.

What’s the GLA catalogue?

The Open Supernova Catalogue on https://sne.space/ contains in excess of 55,000 supernovae. Somewhere between a quarter and a half of these are Type 1a.

> Redshift in the catalogue corrected for the movement of our galaxy

Well I should damn well hope so. The dipole of the cosmic microwave background gives the exact correction.

> The authors removed the correction

They did what! Not worth listening to any more of the video.
