Black holes have infinite density
WebDec 29, 2024 · If it has a region of infinite density, that region must be infinitesimal. But the Planck length is the lower limit on the size of regions of space. There are, therefore, no points in space, no infinitesimals, only punctoids, my term of convenience, the utility of which may become obvious in future posts.And no infinities. general-relativity http://insidescience.org/news/black-hole-cores-may-not-be-infinitely-dense

WebJun 4, 2013 · (ISNS) -- The cores of black holes may not hold points of infinite density as currently thought, but portals to elsewhere in the universe, theoretical physicists say. A … WebThe event horizons of more massive black holes have larger radii. For example, if a globular cluster of 100,000 stars (solar masses) could collapse to a black hole, it would be 300,000 kilometers in radius, a little less than half the radius of the Sun. ... the point of zero volume and infinite density to which any object that becomes a black ...
WebMay 17, 2012 · As energy can be converted into mass, the immensely high gravitational energy in this extremely dense state would cause an intense production of particles, greatly increasing the mass inside the black … WebFirst, you should know exactly what a black hole IS. A black hole is a [00:00:28.00] physical object in space, just like everything else. It’s made up of a tiny but massive [00:00:32.00] point where gravity and density are infinite, a line beyond which everything, [ONSCREEN TEXT: “Singularity”] [00:00:36.00]

WebSep 13, 2013 · A black hole forms when a massive star runs out of the fuel needed to balance out gravity, and collapses under its own gravity to a very small size. General …
WebA black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it! Not everything …
Gravitational singularities are mainly considered in the context of general relativity, where density would become infinite at the center of a black hole without corrections from Quantum Mechanics, and within astrophysics and cosmology as the earliest state of the universe during the Big Bang. Physicists are … See more A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically.
