25 mag 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.

- The singularity constitutes the center of a black hole, hidden by the object’s “surface,” the event horizon. Inside the event horizon, the escape v...

1 giorno fa · A black hole is a region of spacetime where gravity is so strong that nothing, including 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.
4 giorni fa · The Black Hole (TBH) is a non-profit, open-to-all, casual educational and intellectual space for science, art, and culture. Located in the G-11/3 area of Islamabad, it has a 60-capacity auditorium, small library, and a children’s science lab.
20 mag 2024 · As predicted by Einstein's theory of gravity, there's a point at which material stops circling the black hole and falls straight down, plunging precipitously beyond the point of no return. Now, in X-ray data of an active black hole, we've finally seen proof that this 'plunging region' exists.
6 mag 2024 · A backdrop of the starry sky as seen from Earth completes the scene. Tour an alternative visualization that tracks a camera as it approaches, falls toward, briefly orbits, and escapes a supermassive black hole. This immersive 360-degree version allows viewers to look around during the flight.
6 mag 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. Here’s where things get crazy.
16 mag 2024 · Astronomers have found supermassive black holes with masses of millions to billions times that of the Sun in most massive galaxies in the local Universe, including in our Milky Way galaxy. These black holes have likely had a major impact on the evolution of the galaxies they reside in.
