Theoretically, a black hole can exist at any mass as long as it is dense enough. It is true that a black hole won't form without enough mass to cause it to collapse, but once formed, it can evaporate down to nothing without ever becoming gravitationally unbound.
- ansible 8y agoIt has been theorized that tiny black holes may have formed shortly after the Big Bang, and have since evaporated.
- mrkstu 8y agoTheoretically it could evaporate but is there any necessity of that? Is exploding a theoretical possibility or once a stellar mass black hole forms is it thereafter in such a small circumference that it is stuck in that form until it evaporates?
- zaarn 8y agoWell, evaporation is simply a conclusion from hawking radiation. The black hole losses energy over this radiation, energy it produces from it's own mass. Since hawking radiation output increases relative to the size of the black hole as it gets smaller, eventually you end up with an explosion. I do believe that Kurzgesagt made a video that details what would happen with a blackhole with the mass of a coin in your pocket (short version: you die)
