Physicists have proposed a new model for early black hole formation that could account for the unexpectedly large number of ancient black holes observed by the James Webb Space Telescope.

Theoretical physicists have proposed a new mechanism for the formation of black holes in the early universe, potentially explaining the "little red dots" identified by the James Webb Space Telescope (JWST). These distant galaxies appear to contain a higher density of ancient black holes than existing models predicted. The researchers suggest these objects, which they term "not-quite-primordial" black holes, formed before the first stars appeared.

An Alternative to Primordial Models

Existing theories suggest primordial black holes formed during violent space-time events in the early universe. However, these models often conflict with the milder ripples observed in the cosmic microwave background (CMB). To reconcile this, Wenzer Qin of New York University, Neal Weiner of New York University, and Soubhik Kumar of Tufts University proposed that black holes could form within clumps of dark matter. In this model, the heat from the CMB prevents gas and dust from collapsing into smaller structures, allowing larger black holes to emerge.

Testing the New Hypothesis

The researchers are currently preparing to simulate this process to predict the specific light spectrum emitted by these black holes, which will allow for direct comparison with JWST data. While the model is considered less speculative than traditional primordial theories, experts note that concrete evidence is still required. Future observations, potentially from the proposed Primordial Inflation Explorer (PIXIE) satellite, may provide the necessary data to confirm if these black holes existed in the earliest stages of the universe.
