Your description is a bit vague, but it could be a blackhead, which is a pore that is clogged with dirt.
Theoretically, a black hole can destroy anything.
possibly
I don't think you could talk about a "day" on a black hole - for a start, nobody could survive in a black hole, to observe such a day. But if you refer to the rotation, one black hole has been observed that seems to spin over a thousand times per second. This rotation, of course, can be different for other black holes.
No. The black hole at the center of the galaxy is too far away to affect earth.
The mathematics of a black hole itself does not require them. However matter around them will tend to orbit the black hole before eventually falling in, this creates what is called an accretion disk which could be considered a "ring". There is also strong evidence that all spiral galaxies contain a super massive black hole, if this is indeed the case then the entire disk of such galaxies could be considered a second "ring".
The black hole would be the vagina, and the wrinkly piece of skin around it is the women.
the strong force of the black hole means that you cannot live in it
You can't - that's the whole idea of a black hole. Don't get near a black hole in the first place.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Yes a black hole could envelope our solar system but it does not swallow anything.
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
Yes, a black hole could travel through space.
In theory, yes, a black hole could suck up the sun.
Theoretically, a black hole can destroy anything.
If you have a small hole in your thigh skin, this could be caused from a staph infection. It could also be a spider bite. Seeing a doctor will determine the cause.
Since whit holes only exist mathematically, a black hole could not pull in a white hole.
Due to the immense gravity of a black hole, no life we can currently fathom could survive in one.
