The discovery by JWST of a substantial population of compact "Little Red Dots" (LRDs) presented astronomers with a major mystery. By reproducing their spectra with simulations, a team argued that they were Direct Collapse Black Holes (DCBHs).

The FLRW metric is a model. And you know the saying, all models are wrong, but some are useful.

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe capable of producing such energy—100,000 times more than the highest-energy particle ever produced by the Large Hadron Collider, the world's most powerful particle accelerator. However, a team of physicists at the University of Massachusetts Amherst recently hypothesized that something like this could happen when a special kind of black hole, called a "quasi-extremal primordial black hole," explodes.
