No.
No, a black hole is not typically a supernova remnant. A black hole is formed when a massive star collapses under its own gravity, creating a region of spacetime from which nothing, not even light, can escape. On the other hand, a supernova remnant is the leftover material from a massive star's explosion in a supernova event.
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
A black hole or a neutron star.
No! Not even light can escape the black hole!
You are describing a black hole, or singularity.
A black hole forms when the remnants of a supernova collapse under their own gravity, becoming so dense that not even light can escape its gravitational pull. This creates a region of spacetime exhibiting extreme gravitational effects from which nothing, not even light, can escape.
The explosion of a supernova leaves behind either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are extremely dense, composed mostly of neutrons, while black holes are regions of space with a gravitational pull so strong that nothing, not even light, can escape from them.
"after a supernova" is the adverb phrase in the sentence.
Nothing can escape a black hole, not even light.
Adverb: "A black hole forms when a supermassive star collapses after a supernova explosion."
Black holes are created when a star runs out of fuel and collapses. That is a nova, A black hole is made when a neutron star goes SuperNova and the energy tears a hole in space, creating a strong gravitational singularity.
Either a black hole, or a neutron star. That depends on how much mass is left after the supernova explosion.
