How do three recent studies help explain JWST’s “little red dots” and the unexpectedly large population of massive black holes in the early universe—through a less exotic “not quite primordial” formation pathway in which mild dark matter fluctuations and the hot cosmic microwave

Together, the studies point to a layered—not single—solution: some early black holes may have begun as unusually massive pre-stellar seeds, then grown through intense gas accretion and, in interacting galaxies, mergers. They make JWST’s little red dots plausible signposts of this fast-growth phase, but none yet proves that all little red dots share one origin.

• “Not-quite-primordial” seeds: One theoretical proposal suggests that modest dark-matter overdensities could collect gas so early that the still-hot cosmic microwave background helps prevent it from cooling, fragmenting, and making ordinary stars. The gas could instead collapse directly into black holes before stellar populations form—later than truly primordial black holes, but earlier than conventional stellar-remnant seeds. That supplies a much larger starting mass and eases the timing problem for early quasars. It remains a proposed mechanism, not an observation of such a seed. 8

• Close little-red-dot pairs: A COSMOS-Web analysis identified four candidate dual little red dots with projected angular separations of 0.2–1.2 arcseconds, suggesting excess small-scale clustering. 14 If spectroscopy confirms that both members of each pair are at the same redshift and host accreting black holes, galaxy encounters could drive their nuclei together, trigger gas inflows, and ultimately merge their black holes—adding a hierarchical-merger channel to accretion. For now, “candidate pair” is important: projected alignment, physical association, and eventual black-hole coalescence are separate things still to establish. 14

• MoM-BH-1:* The proposed “black hole star” interpretation is a direct example of how a rapidly accreting early black hole can masquerade as a compact red, stellar-looking source. Its spectrum is best modeled as a dense gas envelope energized by a central accreting black hole rather than ordinary nuclear fusion. 1 In the reported model, the core black hole is about 100,000 solar masses and is embedded in an enormous, dense hydrogen cocoon roughly solar-system scale—already a “heavy” seed rather than a black hole born from one ordinary star. 1

The broader implication is that the early universe may have made supermassive black holes by combining three accelerants: heavy initial seeds, sustained or possibly obscured rapid feeding, and merger-driven growth. That is less radical than invoking a vast population of black holes created in the first instant after the Big Bang, but it still requires rare early environments that suppress normal star formation and concentrate gas efficiently.

The key caution is that these are complementary, mostly early-stage results: the first is theoretical, the paired sources need confirmation, and MoM-BH*-1 may represent one class of little red dot rather than the entire population. 8141
