As a black hole becomes more massive, its event horizon expands. No one knows what happens inside the event horizon. Many have advanced different speculations. We know it retains mass and angular momentum.
Our Sun will never become a black hole. It does not have enough mass and thus pressure to initial the sequences required to form a black hole. In about 5 billion years time, our Sun will slowly expand into a red giant, a billion years later it will shed it's outer envelope leaving nothing more that a very hot white dwarf about the size of the Earth. Not that we will be around to see it.
First you will need a large area of space. Next, you will need a Neutron star that is about to die. You will probably need a planet/star if you want to see a black hole consume it. After getting everything, go far out as you can to watch. The neutron star will expand and strange things will happen. The star will expand. Then two gamma ray bursts will appear at both sides of the star. Soon the black hole inside the star will eat the star up and now you will have a black hole. Then the black hole will eat the planet that you put next to it. It will look weird because the immense gravity of the black hole will alter the light around it. The planet/star will be a line. Run away as fast as you can unless you want to die.
Into the black hole's singularity.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
Nothing can escape from a black hole.
No. If no matter enters a black hole it will actually slowly lose mass and shrink via Hawking radiation. A black hole will gain mass if matter fals into, which will cause the event horizon to grow.
it may expand and swallow and swallow us.
No. It simply doesn't work that way.
Stars want to expand when they are active, but their high gravity keeps them the right size. When stars are too old they stop expanding, and its gravity makes it very small. If an object has too much mass for its size, it is a black hole.
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.

A black hole originated as a star, that is, the star converted to a black hole.
If you fall into a black hole, you'll go into the black hole and nowhere else.
probs black hole
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
