'The universe has thrown us a curveball': Largest-ever map of space reveals we might have gotten dark energy totally wrongFindings from the Dark Energy Spectroscopic Instrument (DESI) suggest that dark energy could be evolving over time. If they're right, cosmology will need a new model.

'Impossible' black holes detected by James Webb telescope may finally have an explanation — if this ultra-rare form of matter existsObservations from the James Webb Space Telescope reveal monster black holes in the early universe that seem to have grown too big, too fast. New research points to a strange form of dark matter as a possible culprit.
