Stellar mass black holes form when massive stars die. If you have read How Stars Work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas clouds, their own intense gravity is always trying to collapse them. The fusion reac...
You can also get black holes when dense objects, like neutron stars, collide with one another. And then there are the supermassive black holes at the heart of every galaxy. And to be honest, astronomers still don’t know how those monsters formed....
How collapsing stars might hide their tracks in black holes, ArtículoWhere have all the neutron stars gone? As many as 150 shells of gas and dust left by the recent collapse and explosion of massive stars litter our galaxy, and the standard wisdom predicts that each of them should hold a...
Ultramassive black holes with the most monstrous masses should therefore reside in the brightest galaxies with the most stars. The brightest galaxies at the center of galaxy clusters, known as "Brightest Central Galaxies (BCGs)," would thus be the optimal candidates to harbor ultramassive black ...

In summary: The first stars were much denser than stars today. They left behind black holes when they died. The universe expanded while the first stars ran their life cycle. The typical star pair of the second generation also left a pair of black holes behind when it died. How many ...
Two massive black holes smashed together and completely changed what we know about the universe. This physics-altering collision simply doesn't make sense.
Most black holes are made from the death of massive stars. When the process of fusion stops in massive stars, the star collapses and its core is...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
