Black Hole Question

[DimeUhDozen]

In this scene, a black hole is stated to pull in anything around it using billions of pounds of pressure. It then goes on to state that half the force of that is what Elmyra uses to pull her cat. However, the theory is from the 90s and we know now that's not how black holes work. So I'm wondering, how would this work in more modern and correct terms?

he is right in the part of black holes are the remnants of dead stars, I think he use "billions of pounds of pressure" as a way of referring to one's gravitational pull before the "not return zone", actually technically that would be correct, since it depends on how big it is, it's only when falls directly into the singularity that the gravity rises to infinity

A black hole's force of attraction isn't described in terms of pressure, but rather in terms of gravity. Black holes have only three properties: mass, spin, and electrical charge. The mass of a black hole contributes to its gravitational pull, the spin is related to the rotation of the black hole, and the charge would interact with electromagnetic fields.

“When” falling “into“ a singularity

Gravity does not rise to infinity, density of the body that makes the surrounding space become a singularity does. The infinite space-time curvature is more of a byproduct of that. Not unusual to assume that (gravitational) singularity means the mass itself, but it's more accurate to describe it as a space-time where such mass is found. At least for this example. But singularities are so crazy that I shouldn't talk about them like I know everything when no one really does.

In modern day context, I could see the storyteller explaining how Elmyra has a selective event horizon and that once her cat is close enough, there will be no escape. No amount of mechanical force or speed being enough to escape her.
