And now for something completely different

For a Schwarzschild black hole (a black hole with no rotation or electromagnetic charge), given a free fall particle starting at the event
horizon, the maximum proper time (which happens when it falls without angular velocity) it will experience to fall into the singularity
is π*M ( in natural unit ) , where M is the mass of the black hole . For Sagittarius A * ( the
black hole at the centre of the milky way ) this time is approximately 1 minute .

Schwarzschild black holes is are are also unique because they have a space – like singularity at their core , which mean that the singularity does n’t happen at a specific point inspace but happen at a specific point intime (the future). This means once you are inside the event horizon you cannot point with your finger towards the direction the singularity is located because the singularity happens in your future: no matter where you move, you will “fall” into it.
