Primordial Black Holes

It seems as if cosmologists are currently salivating over the idea of primordial black holes as a way of explaining oddities in the universe. At https://phys.org/news/2024-05-universe-ultralight-black-holes-die.html … we are told primordial black holes ae hypothetical objects  formed in the early moments of the universe. Shortly after Big Bang. Modelling has  shown they might have formed from micro fluctuations in matter density to become grain sized mountain–massed black holes – which are of course theoretically, extremely dense. It then reads, although we’ve never detected primordial black holes they have all the necessary properties of dark matter – another hypothetical wonder. Black holes and dark matter are both completely invisible.There is also a problem for the existence of primordial black holes. To account for dark matter there would have to be an awful lot of primordial black holes – however small they might be. As such, they would very often pass in front of a star – and on earth there are a lot of telescopes pointing at the stars. In fact, a black hole passing a star would cause it to flicker – or obscure its light to a small degree. This has not been mentioned by the many astronomers with telescope time. People have recently gone out of the way to look for oddities to no avail.

At https://phys.org/news/2024-05-black-hole-visualization-viewers-brink.html … here we have a model of a black hole produced by a NASA super computer. It is a simulated journey to a black hole – and its event horizon.
