Black holes do slowly "evaporate" through something called Hawking Radiation. The process is extremely slow and the bigger the black hole the slower it becomes. A black hole the mass of the sun would take about 2x10^67 years to disappear, which is many orders of magnitude greater than the age of the universe.
Black holes do not die but they can evaporate.
The most massive stars will die as black holes.
No. Black holes are the remnants left behind when the very largest stars die.
never
Most black holes are believed to form when very massive stars die.
Yes. When the most massive stars die, their cores collapse to form black holes.
yes
Black holes are stars (suns) that implode when they die. Making a hole that sucks up any material in space.
Dead stars are not necessarily black holes. Dead stars can become white dwarfs, neutron stars, or black holes depending on their mass. Only the most massive dead stars can collapse further to become black holes if they exceed the Chandrasekhar limit, around 1.4 times the mass of the Sun.
Black holes
After black holes, there is not much known in terms of what comes next. Some theories suggest that black holes can evaporate over time through a process called Hawking radiation, eventually leading to their disappearance. Others speculate about the possibility of black holes merging together or transforming into different types of celestial objects. Further research is needed to better understand the fate of black holes and what may come after them.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
