JWST’s mysterious little red dots may be black holes growing at incredible speeds

New supercomputer simulations suggest JWST’s puzzling Little Red Dots are rapidly growing black holes from the early Universe. Extreme radiation may have helped create unusually massive black hole seeds, while dense surrounding gas allowed them to grow dozens of times faster than black holes can today. The simulated objects closely resemble the Little Red Dots seen by Webb.

If correct, they could solve the mystery of how enormous black holes formed so soon after the Big Bang. JWST’s mysterious little red dots may be black holes growing at incredible speeds. Now, new simulations performed with Japan’s ATERUI III supercomputer suggest these objects may be rapidly growing black holes that took advantage of conditions in the early Universe that no longer exist today.

The findings do not require unusual physics or highly unlikely events. Instead, the simulations indicate that Little Red Dots could arise naturally from the environment of the young cosmos, where black holes were able to grow at extraordinary rates.
