It is a mistake trying to cheer up camels. You may as well drop meringues into a black hole.
One of the big mysteries about the black hole at the center of the galaxy is, 'Why don't we see emission from matter falling onto the black hole, or, rather, the black hole eating up its surroundings?'
My life is a black hole of boredom and despair." "So basically you've been doing homework." "Like I said, black hole.
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!
A failure is not always a mistake, it may simply be the best one can do under the circumstances. The real mistake is to stop trying.
When you fall into a black hole, everything that falls in after you over millions of years, as seen by you inside the black hole, comes pounding down on you in a fraction of a second, because of the enormous differences of time flow.
Data suggest that central black holes might play an important role in adjusting how many stars form in the galaxies they inhabit. For one thing, the energy produced when matter falls into the black hole may heat up the surrounding gas at the center of the galaxy, thus preventing cooling and halting star formation.
There's a thing called the 'One Drop' theory in African-American culture, which is if you have one drop of black blood in you, you're black.
If the extrovert is trying to "cheer up" the introvert - extroverts are programmed to seek social rewards! - he or she may feel like a failure if the introvert remains unmoved.
A big misconception is that a black hole is made of matter that has just been compacted to a very small size. That's not true. A black hole is made from warped space and time.
Although almost every theoretical physicist agrees with my prediction that a black hole should glow like a hot body, it would be very difficult to verify experimentally because the temperature of a macroscopic black hole is so low.
Do you realize that if you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into?
Old Camels carry young Camels skins to the Market.
Well, Congress gave us a billion dollars to dig the hole, this gigantic hole. Bigger, much bigger than the hole in Geneva, Switzerland. Then they canceled the machine and gave us a second billion dollars to fill up the hole. Two billion dollars to dig a hole and fill it up. That is the wisdom of the United States Congress and it really makes you wonder: Is there intelligent life on the Earth? Certainly not in the United States Congress.
And learn that when you do make a mistake, you'll surface that mistake so you can get it corrected, rather than trying to hide it and bury it, and it becomes a much bigger mistake, and maybe a fatal mistake.
Our galaxy's pretty ordinary, garden-variety. So if we believe our galaxy has a super massive black hole, that tells us that most, if not all, galaxies host such a black hole at their centers.
One drop of black blood and you're black. That was the rule. That's what kept the wall between whites and blacks was this one drop rule. So I was raised with absolutely no ambiguity about that.
