One of the most energetic explosive events known is a supernova. These occur at the end of a star's lifetime, when its nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast wave that ejects the star's envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron star that can be observed many years later as a radio pulsar.

when it explodes it leaves an area of space whose density is very low.
It may also reduce it's volume but maintains space throughout.
The remnant is a two or so solar mass called a white dwarf.
If the white dwarf accretes matter it will shrink rapidly from 100 km to 12 km,becoming a neutron star.
The evolution of this star is speculated about by many.
If a black hole could exist,that would be it's fate.
Black holes are useless non viable entities.
The neutron star is probably the next step in the demise of the universe.

No. When a star (like our sun) goes through the supernova phase, it gives off the outer layer of gases and leaves the core. The core then becomes a white dwarf, and hangs out for a few billion years. Eventually they cool down and become brown dwarves, basically just a rock in space.

A supernova will either leave a neutron star (a pulsar) OR a black hole if it does not expell enough mass.
And a black hole for sure is a hole in spacetime.

no it just moves all the gas and dust fromthe star outwards at high speed there is usually a residue left over to become a neutron star

I think so, the shock wave sweeps through the interstellar medium making it many times thinner. More like a bubble really.

No. The fabric of spacetime permeates a star, and it just blows up within that fabric. There is no 'hole".

It might leave a black hole, not always though. But I don't think that's what you meant.
