If the mounting evidence of weakening dark energy holds up, it would upend cosmologists’ understanding of our ultimate destiny. @walkingthedot.bsky.social reports:

Given light's energy ,and momentum at galaxy's scale, the inversely proportional matter seems to interact as a spectral fluid, creating matter dynamics (like fluid dynamics).
Dark energy does not exist. The universe is expanding, but that expansion is not speeding up. The studies that led to the idea of dark energy used an assumed average for the density of the universe & that threw off their calculations. There is no average density unless you are working at the scale
of multiple billions of light years. You must figure out the local density the light you are studying has passed through. Such calculations will be easier to make once DESI and Euclid return their results. Ironic considering those telescopes are supposed to study dark energy. Link below.
