It is currently unknown as scientists do not even know what dark matter is.
Well, we don't really know, but probably not because of the intense gravity crushing all material. So gases or their ionized kin would not exist in that form.
No. While we are unsure what exactly is inside a black hole, but our best guess is that it is a singularity, a point of infinite density, which is unlike any other state of matter.
most likely because atoms make everything
Nothing can escape from a black hole.
No you really cant walk inside a black hole, you only float then you die shortly
For all scientific reasons, no astronaut had went inside a black hole. It would take many earth years to visit the black hole, so reaching a black hole is impossible.
No.
At the center of a black hole is a mass that has collapsed to an infinitely dense point.
Nobody knows what is inside a Black Hole, but since there is no gravity inside the event horizon, and energy density is extremely high, it must be more like a plasma.
What Remains Inside a Black Hole was created in 1996.

It disappears forever
No, they are not the same. A singularity would be inside a black hole.

no
No.
No.It is Event Horizon.
It is impossible to know what is present inside a black hole, though it is theorized that a singularity is located at its centre.
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.
