It's just to show that even if a human was standing still, he would still be spinning, but not in the way that we normally think of spinning. So if what i said doesn't come close, then you will hafta splain what kind of not normal spinning you mean.

Not only because the earth is spinning on it's axis, but because the earth is also spinning around the sun, and the sun is also spinning around the Milky Way, ECT. But i don't notice all that spinning, because it is tooo Big, and i am tooo small.

No, I'm saying that neither atomic nuclei nor electrons spin in the sense we think of "spinning". Nothing to do with scale.

Spin results from a transfer of angular momentum, like playing on a children’s swing. If you kick at random times while you swing, you’ll never get very high. But if you kick at the beginning of each downswing, you go higher and higher as you add angular momentum.

Similarly, if the black hole grew randomly by pulling in matter from all directions, its spin would be low. Since its spin is so close to the maximum possible, the black hole in NGC 1365 must have grown through “ordered accretion” rather than multiple random events.

It's really not worth speculating about the inside of a black hole, unless you're a theoretical physicist exploring HIGHLY speculative ideas, most of which barely rise to scientific standards of testability.

When You Fall into a Black Hole, How Long Have You Got?
By George Musser | Scientific American, December 14, 2012 |

<<In chatting with colleagues after a talk this week, Joe Polchinski said he’d love to fall into a black hole. Most theoretical physicists would. They are just insanely curious about what would happen. Black holes are where the known laws of physics come into their most direct conflict. The worst trouble is the black hole information paradox that Stephen Hawking loosed upon the world in 1976. Polchinski and his colleagues have shown that the predicament is even worse than physicists used to think.
........
The least radical conclusion is that the no-drama principle is false. Someone falling into a black hole doesn’t pass uneventfully through the horizon, but hits a wall of fire and is instantly incinerated. “I think it’s crazy,” Polchinski admitted. But in order for a black hole to decay and its contents to spill out, as quantum mechanics demands, the infalling observer can’t see just a vacuum. The firewall idea strikes me as similar to past speculation that black holes are somehow material objects—so-called black stars or dark matter stars—rather than merely blank space.

“I spent 20 years confused by this,” Polchinski said, “and now I’m as confused as ever.” It would be nice to answer the question, if only so that no one ever has to undertake the journey to answer the question.>>
