Can't remember if this was posted on Mastodon or I found it elsewhere but it sure is interesting and makes the brain hurt thinking about it all.

<< A competing theory to 'dark energy' suggests the universe has different time zones >>

I have always had a feeling that Dark Energy was not the answer. But what do I know, I barely got a physics 'O' Level in the UK.

CBCA competing theory to 'dark energy' suggests the universe has different time zones | CBC RadioNew measurements of a certain type of supernova seems to indicate that our expanding universe isn't accelerating at all, negating any need to invoke a mysterious 'dark energy' to explain supernovae observations.

Sometimes a sketch of the larger piece picks off a particular problem without getting too dense. It’s also nice to see some working bits. In context best physics here is basic sampling of current approaches.

"However, that might not happen. We might search and make no headway in understanding the situation. If that happens, we would need to rethink not just our research, but the study of cosmology itself. We would need to find an entirely new cosmological model, one that works as well as our current one but that also explains this discrepancy. Needless to say, it would be a tall order."

@ThreeSigma #StringTheories do and will make testable predictions now and in the future, including for #CMB signature search (right now),#DarkEnergy and #DarkMatter , all well up above Planck. More importantly strings have given us tools that help us think in spacetime topologies that might upset the apple cart.Strings functionally unified quantum mechanics and gravity for the first time ever in one of those. The tools of string theory have wide application in unifying math and physics elsewhere
