How are black holes studied
Web4 de jul. de 2024 · A 2014 study suggested that black holes won’t form at all. The authors suggest that as a star collapses, Hawking radiation during the collapse would reduce the mass of the star sufficiently that the black hole never reaches completion. There would be an ultra-dense body acting like a black hole, but without the singularity or the event … WebThey have studied their dining habits and how fast they spin. They found a black hole that generated the deepest note ever detected in the Universe, and another that generated the most powerful explosion. They found direct evidence for a star that was torn apart by a supermassive black hole.
