there is secondary evidence of a black hole. there is only secondary, because a black hole can be detected by its surrounding, such as the radiation an object gives off as it is being sucked in.
The observation of an astronomical phenomenon which was subsequently called a 'black hole' is a fact; ergo, the black hole is a fact. The theoretical explanation of a black hole can be opinion, but it is normal based upon the theory of general relativity; which gains more favor with a consensus.
no the galaxy is way to big for a black hole to do much in fact we now know that there is a supermassive black hole in the center of our galaxy right now.
A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.
Yes, you will. In fact, upon entering the event horizon of a black hole, you will firstly be stretched like a piece of spaghetti, and will suffer a quick death.
Sadly, absolutely nothing can withstand living in a black hole.. In fact, you would need infinite energy just to stay in its orbit. So you cant live in a black hole, but you might be able to live close to it.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

In fact you would die outside a black hole. At least in the case of a stellar-mass black hole, the tidal forces, i.e. difference in gravity between your head and your feet, would be strong enough to tear you apart before you reach the event horizon.
A black hole could potentially consume Jupiter if it entered the black hole's event horizon, the point of no return. However, the likelihood of Jupiter encountering a black hole and being sucked up is extremely low due to the vast distances between objects in space.
Stephen Hawking once came up with an argument that black holes aren't completely black, but they emit small amounts of radiation. Since the energy that produces the black hole comes from its mass, the black hole gradually shrink. In fact, the smaller the black hole, the faster it shrinks due to this radiation.
No - In fact, the Chandra X-ray Observatory detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth.
First, you will notice that time is getting slower (you will notice that distant stars changes quickly. As a matter of fact, this is not time outside the black hole that is faster, but it's the time inside the black hole that is getting slower.) Then the gravity will get so high that you will be ripped into pieces.
A black hole originated as a star, that is, the star converted to a black hole.
