Anything that gets too close to the dark hole will fall into it, and be destroyed.
No, but some stars end their life by becoming a black hole.
Don't know which black hole.
Some stars become a black hole or a black dwarf.
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.
No, the black hole at the north pole will not kill us all. Black holes are typically formed from the collapse of massive stars and are not known to be present in our solar system. The nearest black hole is many light-years away and poses no immediate threat to Earth.
Black holes do not actively seek out planets to destroy. However, if a planet were to get too close to a black hole, the intense gravitational forces could disrupt or even pull the planet into the black hole. So, in that sense, a black hole has the potential to "kill" a planet by tearing it apart.
stars explode
black hole
I don't think that either of these stars "have" a black hole.
Stars do get sucked into a black hole if they pass the event horizon.
No, but some stars can end their lives by becoming a black hole.
no black holes are stars
