No. Although there is mathematical evidence that black holes can decay though something called Hawking Radiation, what results cannot form new stars. The time it takes for a black hole to decay is far longer than the current age of the universe. New stars are formed when nebulae collapse.
No. Only the most massive stars form black holes. When the sun dies it will form a white dwarf.
Only stars that are much more massive than our sun can become a black hole. When the star dies, it explodes (called a supernova) and then gravitational collapse helps it to form a black hole.
black hole
No, they form whenever a star dies, which can happen from two seconds after another black hole forms, or it could be 100 years before the next one forms. Point: They form at random. Answer: Contrary to the previous answer black holes do not form every time a star dies. For the formation of a black hole the star needs to be large (in terms of stars as a whole - our own Sun is too small to become a Black Hole).
when a star dies
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole
they trun into a black hole
It cannot. The sun does not have enough mass to form a black hole. When it runs out of fuel an dies it will form a dense remnant called a white dwarf. Only stars 25 times the mass of the sun or more have strong enough gravity for their cores to collapse all the way to a black hole.
The sun's energy has not formed a black hole.
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.
The mass of the remaining core of a star that has exploded as a supernova. (Although some stars can collapse directly to a black hole without a supernova explosion)If the mass exceeds about 3 to 4 solar masses the degeneracy pressure of neutrons is insufficient to stop the collapse, and the object will inevitably collapse into a black hole.See related link for more information.
Stars that are too massive to form neutron stars can undergo a supernova explosion and collapse into a black hole. This process occurs when the core of the star collapses under its own gravity, creating a region with infinite density and strong gravitational pull from which not even light can escape.
