Gravity is stronger in a black hole, if that's what you mean. It's in a black hole that space and time are distorted to such an extent that not even light can escape.
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
A neutron star or a pulsar, or a black hole.
when a star dies
When it turns into a black dwarf neutron star or black hole.
A black hole or a neutron star.
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
Either a neutron star or a black hole.
