Is it possible for a black hole to have its schwarzschild radius less than its actual radius?
- martinLv 72 months agoFavorite Answer
Yes. Photographs of black holes seem to show two different boundaries, like a circle within a bigger circle.

In that case, it wouldn't be a black hole. It would be a star or planet. The definition of a black hole is a body whose entire mass squeezes inside its Schwartzchild radius.
By the way, the actual radius of any black hole is zero. All the mass is at a point.

No and the reason is the extreme density of the mass. You need to read more:

Because it is the last point before the Singularity

No... the definition of the Schwarzschild Radius is the point on or out from a mass where the escape velocity equals the speed of light... and, that's *also* where the Event Horizon of a black hole is - so, the Schwarzschild Radius can't be less...

What does "actual radius" mean to you? If you're thinking about some solid surface, like a planet or neutron star, then the answer is no. The thing at the center of a black hole is much smaller than the Schwarzschild radius, even for a rotating BH.

No, it isn't. That even holds for "mini-black holes".

dont under-estimate the power of the schwarz ...
