The only thing that can escape a black hole are things that come from outside the event horizon, from particles to conventional photons to even the Hawking radiation that get their energy from the black hole's mass itself.
Other than that nothing else can escape a black hole because of their enormous, space-bending gravity, everything that falls into the black hole is instantly ripped apart and lost.
Black holes do spin and deep radio imaging has revealed that supermassive black holes in a region of the distant universe are all spinning out radio jets in the same direction most likely a result of primordial mass fluctuations in the early universe.
A black hole will not hit the earth or devour the earth.
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe.
It is incredibly unlikely that Earth would ever fall into a black hole.
This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
We are inside a black hole as the birth of our universe is thought to have come from a black hole.
Most experts agree that the universe started as an infinitely hot and dense point called a singularity.
Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang.
However, it's plausible that what we see from inside our Universe is simply the result of being inside a black hole that formed from some parent Universe.
A black hole is a cosmic body of extremely intense gravity from which even light cannot escape.
Black holes usually cannot be observed directly, but they can be “observed” by the effects of their enormous gravitational fields on nearby matter.
A black hole is a region of spacetime where gravity is so strong that nothing – no particles or even electromagnetic radiation such as light – can escape from it.
The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down.
And it doesn't really exist.
It's unlikely, however, that any star ever came close enough to knock the other large bodies in our Solar System off course.
The closest we can expect another star to have come, over our entire planet's existence, is about ~500 A.U. away, or about ten times the distance from the Sun to Pluto.
Black holes are freezing cold on the inside, but incredibly hot just outside.
The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.
The birth of our universe may have come from a black hole.
Most experts agree that the universe started as an infinitely hot and dense point called a singularity.
Will the Sun become a black hole?
No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.
