Yesterday my friend on Discord sent me an article on this new black hole called The unicorn
and i got very intersted and i found these articles for other people to read up on https://www.space.com/tiny-black-hole-unico...losest-to-earth and here is the arxiv.org article https://arxiv.org/abs/2101.02212 apparently it orbits a big bloated red giant star |

There is also the interesting / bizarre possibility that colliding stars of degenerate matter (electron, proton, neutron or quark) could form a "synestia"- https://www.ucdavis.edu/news/synestia-new-t...lanetary-object
In that case, the central core collapses to a fly-weight black hole (boxing reference) while the remainder of the degenerate matter is flung out into a torus where it is under comparatively low gravity. Hmm, is it theoretically possible to create a "degenerate matter eutectic"? In simplest terms, you'd have a white-dwarf "sauce" mixed in with a neutron star's "nuclear pasta"? |

Greenish, that Matt Dowd video is a very good connection to make. The Unicorn paper discusses LIGO discoveries as comparable cases; they may not be the same thing, but they're part of the same range of mass and density and presence in a coorbital binary. The Dowd video gives a good sense of what we do and don't know about bodies in this mass range so far.
