SOLAR SYSTEM

Detailed explanation-1: -A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape its event horizon. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Detailed explanation-2: -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.

Detailed explanation-3: -Although the basic formation process is understood, one perennial mystery in the science of black holes is that they appear to exist on two radically different size scales. On the one end, there are the countless black holes that are the remnants of massive stars.

Detailed explanation-4: -Nothing that falls into a black hole can come back out again–at least not in its original form. But a black hole may lose some of its mass. Quantum theory says that “virtual pairs” of particles sometimes wink into existence from the fabric of space itself. These particles quickly cancel each other out and vanish.
