The singularity is the heart of a black hole.

The black hole material's shape is a mystery. The researchers think, that there is an ultimate dense object in the black hole event horizon. That object is called a singularity. In singularity, all atomic and subatomic particles, along with quantum fields form one entirety. That ultimate dense object is a mystery because the outcoming quantum fields cannot fill it. 

So how the supernova explosion can form a black hole? Maybe the answer is in the films, where the explosion happens under the bridge. The explosion pushes gas out from below the bridge. And then the vacuum below the bridge pulls it down. Or we can think. The air statue above the bridge pushes it down. 

When a supernova explosion happens it pushes quantum fields away from the star remnants. At the beginning of the explosion the star falls. The supernova explosion happens when the outcoming material impacts against the shell of the core of this structure. And that means. The beginning of the shockwave begins at the ball-shaped area around the star's nucleus. The nucleus is the material that forms the singularity. 

Maybe the singularity is an extremely small 2D structure that stands like a coin on the event horizon. The singularity material acts like the fast-spinning coin in the middle of a black hole's nucleus. That extremely fast spin makes the material or disk-shaped structure act like a centrifugal sling. 

All explosions are similar. The difference is their power. But basically, the normal explosion interacts with the environment, in the same way as supernova explosions. But their scale and power are different. 

The black hole does not create gravity. It just transforms other energy forms into gravity. 

That 2D material structure can be in a ball-shaped field or superstring structure. That thing rotates in two ways. The standing axle and the spin axle would both rotate. And that thing makes this strange, hypothetical structure act like a centrifugal sling. The plate that could be in a standing position against the material disk harvests and aims energy to the poles of a black hole. That thing explains why the black hole can keep its quantum vacuum that pulls material and quantum fields into the black hole. 

The shockwave starts to travel out from the ball-shaped core and pulls the electromagnetic or quantum vacuum around those particles. That thing makes energy travel out of them very fast. And then. That thing pulls the particles into a saucer-shaped 2D structure. That 2D material spins extremely fast. That extremely fast spin causes the effect, that we can see when some plate rotates in water or some other liquid. That spin pushes quantum fields away from those particles' core. 

In this text, the larger area of 2D particles is up. And a thin area or the edge of the plate is horizontal. The upcoming quantum field presses against those particles. But the extremely fast horizontal spin pushes that quantum field away from its sides. That means the 2D particle transfers the falling quantum fields to its sides. If that thing is true the singularity is like the coin or standing coin in the middle of the event horizon.
