"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
The three corpses of stars are white dwarfs, neutron stars, and black holes. White dwarfs are remnants of low to medium-mass stars that have shed their outer layers, leaving behind a hot core. Neutron stars form from the collapse of massive stars in supernova explosions and are incredibly dense, composed mostly of neutrons. Black holes result from the gravitational collapse of very massive stars, creating regions in space with gravity so strong that not even light can escape.
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
In all probability - not that this scenario would happen - but the resulting combination of masses, would push the combined "stars" over the Chandrasekhar limit and a black hole would form.
NothingGravity isn't made of anything. It is not an object and is not made of matter; therefore, it has no mass. Gravity is a force. If you use the Search tool at the top of the page and search on "gravity," many questions will be displayed that you can explore.*While this is the currently the accepted answer by society, in truth no one knows what gravity truly is. The term "force" is a generalization used to define what they do not understand.Addition:There is a theory that gravity is made up of massless, uncharged particles called "Gravitons". This theory isn't widely accepted because gravity doesn't work on a small atomic scale. The theory is called Quantum Gravity.
Yes. When the most massive stars die, their cores collapse to form black holes.
Most black holes are believed to form when very massive stars die.
All dead big stars do not form black holes because sometimes the collapse of the star is stopped at a smaller size before it becomes a black hole.
Yes. When the most massive stars die, their cores collapse to form black holes.
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.
Mostly in galaxies, where they can form Super Massive Black Holes.
No. Only the most massive stars form black holes. When the sun dies it will form a white dwarf.
Black holes form when massive stars collapse under their own gravity. The intense gravitational pull of a black hole traps everything, including light. Black holes are hot because of the high temperatures and energy generated by the matter falling into them, which creates intense radiation and heat.
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.
