General relativity predicts that any object collapsing beyond a certain point (for stars this is the Schwarzschild radius) would form a black hole, inside which a singularity (covered by an event horizon) would be formed.
9 de feb. de 2022 · The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space...
A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Penrose’s singularity theorem. Penrose proved that singularities – and by extension black holes – form generically in general relativity, without stringent symmetry assumptions and for general properties of the matter. Penrose’s key insight was to focus on how the gravitational force affects light.
The Penrose singularity theorem is a theorem in semi-Riemannian geometry and its general relativistic interpretation predicts a gravitational singularity in black hole formation. The Hawking singularity theorem is based on the Penrose theorem and it is interpreted as a gravitational singularity in the Big Bang situation.
20 de may. de 2020 · The singularity in a Schwarzschild black hole is a so-called spacelike one—that essentially “cuts off time” for any geodesic, anywhere in space inside the event horizon. Discovered 50 years after the Schwarzschild solution is the Kerr solution , representing a rotating black hole.
10 de jul. de 2024 · If confirmed, at a distance of 17,700 light-years the candidate black hole resides closer to Earth than the 4.3-million-solar-mass black hole in the center of the Milky Way, located 26,000 light-years away. Omega Centauri is visible from Earth with the naked eye and is one of the favorite celestial objects for stargazers living in the southern ...
18 de may. de 2024 · New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with universe-expanding dark energy.
The singularity at the heart of a black hole produces heat so intense that extremely bright radiation is blasted out in every direction (Credit: Nasa)
Hace 6 días · The prospect of actually resolving the event horizon of black holes feels like the stuff of science fiction, yet it is a reality. ... They have a complex anatomy with a singularity at the center ...
