The Kerr black hole is probably the most common black hole formation in nature. Where do black holes lead to? If a massive object crosses the event horizon, it will be sucked into the black hole and never escape. What happens inside the black hole is unknown; even our current theories of...
Their exceptional nature comes from the fact that they’re super-condensed and the force of gravity increases as distance decreases. So it’s possible for an orbiting object to stray into a region where gravity becomes incredibly strong. At larger distances, however, a black hole’s gravity is...
Several theories have been proposed to describe the formation of black hole seeds in the early Universe and to explain the emergence of very massive black holes observed in the first thousand million years after the Big Bang1,2,3. Models consider different seeding and accretion scenarios4,5,6,...
When black hole pulls something in, its event horizon supercharges the particle close to the speed of light, producing sound. The space-based telescopes capture sound waves that have already traveled millions of light-years from their source (black hole). But sound can’t travel in a vacuum,...

In subject area: Physics and Astronomy A Schwarzschild Black Hole is defined as a region in space where the gravitational field is so strong that light cannot escape, resulting in a singularity at the Schwarzschild radius. AI generated definition based on: Special Relativity, Electrodynamics, and ...
The dust obscures emission from accretion, while the star formation masks it. Furthermore, if the correlation between black hole mass and bulge mass applies, the black holes in smaller galaxies are less massive, which makes their emission weaker. Dynamical evidence for black holes in low-mass ...
black hole formation we assume, however, that without black holes the gravitational field is not entangled with other quantum systems. From this standpoint the black hole information paradox is explained, at the kinematic level, by entanglement between the gravitational field and other degrees of ...
By imaging it, "we want to see if the image agrees with the predictions of the general relativity," he said. "But our ultimate desire is to understand the formation of the universe." The donut-like black hole image was created by the Event Horizon Telescope (EHT) -- a planet-scale ar...
Quantum-mechanically, the black hole evaporates [3] and unitarity requires that along the evaporation process the black hole should deliver back the information which was classi- cally hidden in its interior [4]. This means that although the classical metric has no hair, the evaporation products ...
