JWST spots a strange red dot so extreme scientists can’t explain it

SMRTR summary

JWST discovered mysterious tiny red dots that have baffled scientists because they don't match any known astronomical objects. These extremely distant objects, whose light traveled 12 billion years to reach us, initially sparked theories about dense galaxies or dust-covered black holes, but neither explanation fit the data. Researchers studying the most extreme example, nicknamed "The Cliff," have proposed a new model called "black hole stars" - supermassive black holes surrounded by thick hydrogen gas envelopes that mimic stellar appearances.
