The claim is that scientists made a further step towards understanding dark energy – see https://phys.org/news/2021-04-scientists-dark-energy.html … via the 'Bryon Oscillation Spectroscopic Survey' – otherwise christened BOSS. It involves the Chinese Academy of Sciences who are said to have detected dark energy.

Muons are described as an unstable larger cousin of the electron. They contain a magentic anomaly. An experiment to challenge the Standard Model is in progress. Might be all hot air. What seems to be involved is magnetism and how it interacts with particles. A learning curve for all concerned.
