- 2:40Compact, luminous little red dots challenge explanations of how massive objects formed so early in the universe.
- 6:05Dusty galaxies and feeding black holes offer explanations, but missing expected signals complicate both.
- 11:27MOM-BH*-1's sharp spectral drop supplies the central clue Brown connects to a possible black hole star.
- 13:56Radiation from gas feeding a black hole could support a vast surrounding hydrogen envelope.
- 17:27Disputes over mass estimates and spectral broadening leave the interpretation open to scientific debate.
- 20:51Gravitational lensing produces multiple delayed images of one red dot, revealing changes in its brightness and colour.
What stops a vast cloud of gas from collapsing into the black hole hidden at its centre? In AstroKobi's explanation of a quasi-star, the answer is light: radiation from gas feeding the black hole pushes outwards, supporting the enormous envelope around it.
That strange balancing act is the heart of his documentary, "JWST Just Found A Black Hole Inside A Star". The title sounds settled, but the video explores a candidate and the scientific debate around it, rather than an undisputed discovery.
Kobi Brown starts with the James Webb Space Telescope's mysterious "little red dots", compact, bright objects seen in the early universe. He walks through possible explanations, including dusty galaxies and feeding supermassive black holes, and explains why missing X-ray and mid-infrared signals complicate the picture.
The most specific clue arrives around eleven minutes in. A candidate labelled MOM-BH*-1 shows a dramatic drop in its light spectrum, which Brown explains as strong absorption by hydrogen. That leads into the quasi-star idea: a black hole wrapped in an immense gas envelope, resembling a star but powered by material falling towards the hole rather than ordinary stellar fusion.
Brown uses animation to unpack that structure, then turns to disagreements over black hole masses and how to interpret the light. Viewers are picking up on the distinction too: some question the certainty of "just found", while others marvel that a tiny red dot could conceal something so enormous.
The documentary includes a sponsored university segment. Its final stretch returns to the observations, showing how gravitational lensing splits one distant object into multiple images, offering different delayed views of its changing brightness.

Hard to believe that tiny red dot could be hiding something like this.
@CurioThreadStudioSee it on YouTubeso black holes just be spawning anywhere now like corrupt minecraft terrain
