A Quote by Stephen Hawking
There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time.

There are no black holes in the sense of regimes from which light can't escape to infinity.
How do you observe something you can't see? This is the basic question of somebody who's interested in finding and studying black holes. Because black holes are objects whose pull of gravity is so intense that nothing can escape it, not even light, so you can't see it directly.
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.
Black holes provide theoreticians with an important theoretical laboratory to test ideas. Conditions within a black hole are so extreme, that by analyzing aspects of black holes we see space and time in an exotic environment, one that has shed important, and sometimes perplexing, new light on their fundamental nature.
It's hard to know which stars in the sky will turn into black holes. And which ones will open up worm holes into entire new universes.
Black holes are enigmatic astronomical objects, areas where the gravity is so immense that it has warped spacetime so that not even light can escape.
I've opposed black regimes and white regimes, leftist regimes and rightist regimes. I'm close to Aristide because I have respect for him, but all that is beside the point.
The light which shines in the eye is really the light of the heart.. The light which fills the heart is the light of God, which is pure and separate from the light of intellect and sense.
The car shot forward straight into the circle of light, and suddenly Arthur had a fairly clear idea of what infinity looked like. It wasn’t infinity in fact. Infinity itself looks flat and uninteresting. Looking up into the night sky is looking into infinity—distance is incomprehensible and therefore meaningless. The chamber into which the aircar emerged was anything but infinite, it was just very very very big, so big that it gave the impression of infinity far better than infinity itself.
You do a movie. However long it lasts, it begins and it ends in a relatively short period of time. In a given period of time, let's say a year, you can have three, four, or five different experiences which is exciting.
We have this interesting problem with black holes. What is a black hole? It is a region of space where you have mass that's confined to zero volume, which means that the density is infinitely large, which means we have no way of describing, really, what a black hole is!
I'm a big fan of Tarantino's work, and I think I'm fascinated by his evident sense of entitlement to use black characters and black material that he feels not simply comfortable with, but that it's his right and privilege - the apparent ease with which he handles black characters, fully aware that he's been criticized for that, too.
A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.
Finding the first seed black holes could help reveal how the relation between black holes and their host galaxies evolved over time.
Can a society in which thought and technique are scientific persist for a long period, as, for example, ancient Egypt persisted, or does it necessarily contain within itself forces which must bring either decay or explosion?
Faced with today's problems and disappointments , many people will try to escape from their responsibility. Escape in selfishness, escape in sexual pleasure, escape in drugs, escape in violence, escape in indifference and cynical attitudes. I propose to you the option of love, which is the opposite of escape.
