Einstein’s general relativity says that when matter is pulled into a black hole, its information is destroyed – but quantum mechanics says that cannot happen. As a result, black holes are an incredible theoretical playground for astrophysicists and mathematicians, attempting to reconcile the two theories.

8 de sept. de 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.
6 de may. de 2024 · May 06, 2024. Article. Ever wonder what happens when you fall into a black hole? Now, thanks to a new, immersive visualization produced on a NASA supercomputer, viewers can plunge into the event horizon, a black hole’s point of no return. NASA Simulation’s Plunge Into a Black Hole: Explained. Watch on.
23 de sept. de 2019 · A black hole is an extremely dense object in space from which no light can escape. While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.
3 de may. de 2023 · Black holes are extremely massive, but that mass is concentrated in a smaller area, creating a high density that increases the maximum force of a black hole’s gravity by allowing objects to get very close to all of that mass. When an object gets “too close,” it will start to experience tidal forces.
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.
