5 days ago · 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. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Jun 29, 2024 · Learn about black holes, cosmic bodies of extremely intense gravity from which nothing, not even light, can escape. Find out how they are formed, what types exist, and how they are observed and studied.
1 day ago · One theory that has been around since 2002 is that black holes don’t actually exist. Instead, what we have previously labeled black holes are actually gravastars. Gravastars, the theory goes, are formed at a point during the collapse of large stars. An intense amount of gravity transfers its matter into a new state.

Jun 13, 2024 · A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
6 days ago · A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single supermassive black hole.
Jun 17, 2024 · Black holes occur when a giant star explodes and the core collapses into a tiny black spot. They are impossible to see but weigh enough to swallow everything around them. Black holes are memorials to dead giant stars, but they are also spectacular phenomena in their own right.
