Because the bug nebula's (NGC 6302) central star, a white dwarf, is only about two thirds solar mass, it is unlikely to become a black hole. It would need to be about five times its current mass to overcome degeneracy pressure.
The galactic centre is the central region of a galaxy. Most, if not all galaxies have a supermassive black hole at their centre.
Theoretically, a black hole can destroy anything.
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.
A black hole on your skin could be a mole or a freckle. It is important to monitor any changes in size, shape, or color of the black hole, as it could be a sign of skin cancer and should be checked by a healthcare professional.
No, in our universe, virtual assistants exist in the digital realm and do not have physical mass that could collapse to form a black hole. The concept of a virtual assistant turning into a black hole does not apply in our context.
Not entire nebulae. The gravity of a black hole is said to be inescapable, but this is only technically true for matter that crosses the event horizon. If too much matter falls into a black hole, not all of it will be able to fit. Some will be ejected in jets at the poles of the black hole at close to the speed of light. Other matter may simply be flung out. The intense radiation from this process can drive gasses away.
A central, supermassive black hole.
The galactic centre is the central region of a galaxy. Most, if not all galaxies have a supermassive black hole at their centre.
You could get sucked up by a black hole if you were close enough to feel its gravitational pull more strongly than another force to counterbalance it which would otherwise prevent you from getting sucked inside, such as, for example the orbital inertia which prevents the stars in our galaxy, including the Sun, from getting sucked into the Milky Way's central supermassive black hole.
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.
Roughly speaking, the larger galaxies tend to have larger central black holes.
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
In theory, yes, a black hole could suck up the sun.
Theoretically, a black hole can destroy anything.
