      And they can reach close to lightspeed while flying through space… One could be heading right for the sun and we’d never even see it coming…

      They think 35-50% of black holes might be obscured by like interstellar dust and such, instead of the 15% that is more commonly estimated, apparently.

      And because the universe is huge, those tens of percents add up to billions or even trillions.

      What’s the smallest theoretical size a black hoke can be? Is there a certain amount of mass required to cause a singularly to form?
