- andrewflnr 3y agoFWIW, the sun's schwarzchild radius is more like inches than Angstroms. Still small compared to the sun, but not that small.
- pdonis 3y ago> the sun's schwarzchild radius is more like inches than Angstroms. No, it's not inches, it's about 3 kilometers. But the holes at the center of stars that the paper is talking about have tiny masses, much, much smaller than those of the stars they are inside. Their schwarzschild radius could indeed be of the order of Angstroms.
- andrewflnr 3y agoOops. I didn't remember it being that much bigger than Earth's.
- Sharlin 3y agoThe article is not talking about solar-mass BHs but ~asteroid-mass ones, with a Schwarzschild radius on the order of nanometers to micrometers.
- hinkley 3y agoHow do you catch a molecule sized black hole? Maybe in stellar nurseries? But then the black hole has been feeding for a very long time. Yes?
