We do not know how the universe began, or what the exact sequence of events were.
Well, a singularity is part of a black hole. Although no-one really knows what existed before, a likely explanation is that every black hole contains another universe. So when our black hole was created, we were too.
No the singularity is at the core of the black hole.
The Big Bang theory does indeed suggest that the begining of the Universe was a singularity - an infintesimally small region where the entrie Unverse was concentrated. A singularity is also thought to be at the centre of a black hole.
No, they are not the same. A singularity would be inside a black hole.
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
It is not known what happens to matter inside a black hole. The point of origin of the universe is currently believed to be the Big Bang, which is different from a black hole. The gravitational pull of a black hole is so strong that matter is compressed to a point of infinite density at the singularity, according to general relativity.
A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.
Into the black hole's singularity.
A singularity is at the centre of a black hole.

Not exactly. The singularity is in the center of the black hole. Somewhat like a peach pit is in the center of the peach but it isn't the peach but part of it.
Black holes are created in space by extremely massive stars collapsing in on themselves. This happens because the star has run out of fuel and can no longer withstand against the force of gravity, so it must collapse. When the star collapses, matter is compressed to a singularity (an infinitely dense point of space in the universe). There are 3 basic parts of a black hole: the event horizon, the inner horizon, and the singularity itself. When objects such as stars or gas clouds get swept into the event horizon, it is the point of no return. The object is slowly sucked towards the core (the actual black hole). The object is then sucked into the inner horizon. Something bizarre happens at the inner horizon. Matter is transported to one of two narrow laser like beams. Matter is either enters the beam that goes against the spin of the black hole that has positive energy and moves forwards in time, or enters the beam that goes with the spin of the black hole that has negative energy and moves backwards in time. The two beams are then shot into space at nearly the speed of light. The singularity is the most dense point of the universe. The singularity is where the universe was created and time was made, and where time and the universe ends. Just never go into a black hole...
