Yeah, the event horizon the size of a Planck unit. Again, unless you get super close, it acts identical to a regular planet of the same mass.

- gizmo686 6y agoDo we actually have a theory that predicts a theoretical minimum size of a Planck length? Black holes are an artifact of gravity and the theory of relativity. The planck unit comes up as a result of quantum mechanics. Without a working theory of quantum gravity, we do not have a description of what happens in scenerios where both theories are relevent.
- QuesnayJr 6y agoThere's an approximation that's expected to hold, semiclassical gravity, where both theories are relevant. This is the background against which calculations of Hawking radiation and black hole evaporation are made.
