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 · Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and infinite density called the singularity.
Sep 8, 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
May 6, 2022 · Black holes are real, they're some of the strangest objects in space. Discover what black holes are and how they form with our informative black hole guide.
Jul 1, 2021 · Physicists at MIT and elsewhere have used gravitational waves to observationally confirm Hawking’s black hole area theorem for the first time. This computer simulation shows the collision of two black holes that produced the gravitational wave signal, GW150914.
A supermassive black hole’s intense gravity can cause stars to orbit around it in a particular way. Astronomers tracked the orbits of several stars near the center of the Milky Way to prove it houses a supermassive black hole, a discovery that won the 2020 Nobel Prize.
2 days ago · A black hole is an area of such immense gravity that nothing—not even light—can escape from it.
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity.
2 days ago · New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.
What is a black hole, really? What do they look like, eat, and how do they grow? What’s inside a black hole? Learn the answers to these questions and more.
