Reply to comment by Muvlon in Ultramassive black hole over 30 billion times mass of our sun has been spotted. The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga

It's the gravitational acceleration at that distance from a body of that mass, at least based on the random internet calculator I used. (~500 m/s^(2))

Under that kind of gravity, it doesn't really matter how big you are or what your orientation is. The gradient isn't going to be enough to spaghettify you. It might matter if you want to build a large structure in close orbit around the black hole, but even then, a reasonably sized, properly engineered steel-reinforced structure should be able to handle that level of stress.

Ah, so it's the gravitation acceleration for a still standing obverser, not an infalling one or one that is in orbit.
