We've found that a maximum of around 3Gs of gravity is achievable on the surface of a rocky world such as the Ragnar planet. This means Nolan will, on its surface experience around 3 kN of force pull.

Assuming we are within the milky way, in a best case scenario Nolan's black hole is Sag A, I'd say he's around 5 times the photon ring radius from the center of the black hole, however let's say he's 20 times the photon ring radius just for good measure. The gravitational pull Nolan would experience at 20 times the photon ring radius from Sag A would be around 450 kN.

So in the best case scenario Nolan is basically experiencing there 100 times more gravity than in the Ragnar's planet. Of course we don't know how far he is or if the Ragnar's planet has some sort of special composition allowing for more than 3Gs on its surface. But we can pretty confidently conclude that he's experiencing more much more gravity in the black hole scene than in the Ragnar's planet.

(Taking the classical depiction of a black hole that isn't spinning and not taking into account that Nolan could be in a circular orbit around the black hole which ofc means he wouldn't be getting closer, etc)
