There seems to be this sense among even well-meaning Americans that Africa is this black hole of murder and mutilation that can never be fixed, no matter what aid is brought in.
Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.
anymore time in that black hole and ill go insane.
If I'm feeling hurt, sad, lonely, depressed, and then I shame myself for feeling that, then that's a black hole for me. I really have worked a lot to meet pain with both gratitude and gentleness.
Just as with cars, it's critical to know the fuel efficiency of black holes.
An event horizon, or the point of no return, is only a byproduct of the bending of space. However, electricity and magnetism, by themselves, have no event horizon. It gets complicated, however, if a black hole has charge, and then this new solution does have an event horizon.
There is nothing as dreamy and poetic, nothing as radical, subversive, and psychedelic, as mathematics. It is every bit as mind blowing as cosmology or physics (mathematicians conceived of black holes long before astronomers actually found any), and allows more freedom of expression than poetry, art, or music (which depends heavily on properties of the physical universe). Mathematics is the purest of the arts, as well as the most misunderstood.
This year I'm a star, but what will I be next year? A black hole?
I'm a child myself, in the sense that I'm still looking. Children are fascinated by black holes and ask me questions. I find they soon get the idea if it is explained in nontechnical language.
The teaching of the buddhas is: Find time and a place to remain unoccupied. That's what meditation is all about. Find at least one hour every day to sit silently doing nothing, utterly unoccupied, just watching whatsoever passes by inside. In the beginning you will be very sad, looking at things inside you; you will feel only darkness and nothing else, and ugly things and all kinds of black holes appearing. You will feel agony, no ecstasy at all. But if you persist, persevere, the day comes when all these agonies disappear, and behind the agonies is the ecstasy.
Macroscopic objects, as we see them all around us, are governed by a variety of forces, derived from a variety of approximations to a variety of physical theories. In contrast, the only elements in the construction of black holes are our basic concepts of space and time. They are, thus, almost by definition, the most perfect macroscopic objects there are in the universe.
If travel has momentum and wants to stay in motion, as I mentioned earlier, then adventure has the gravitational pull of a black hole. The more you do it, the more you find a way to keep doing it.
It is a mistake trying to cheer up camels. You may as well drop meringues into a black hole.
The most accessible field in science, from the point of view of language, is astrophysics. What do you call spots on the sun? Sunspots. Regions of space you fall into and you don’t come out of? Black holes. Big red stars? Red giants. So I take my fellow scientists to task. He’ll use his word, and if I understand it, I’ll say, “Oh, does that mean da-da-da-de-da?
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.
I have one good characteristic: I'm a pessimist, so I always imagine the worst - always. To me, the future is a black hole.
Remember the referendum on the Charlottetown constitutional accord? The more Canada's political and business elites threatened Canadians that the country would disappear into a black hole if the accord weren't passed, the more Canadians opposed it.
There is no Christian Gospel if history simply unwinds into a meaningless puddle, if the cosmos simply escapes into a cataclysmic black hole, or if the universe finally dies of exhausted energy. Without belief in a biblical eschatology, there is no Christian hope. Without a sense of perfect moral judgment in the end, the human heart is homeless.
A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like air in a tornado.
Gravitational waves will bring us exquisitely accurate maps of black holes - maps of their space-time. Those maps will make it crystal clear whether or not what were dealing with are black holes as described by general relativity.
What I do for living, working on something called string theory which we think may answer the fundamental question: Are there other universes? Can you go through a black hole? Can you warp the fabric of space and time and meet your mother before you were born? These are all questions that in principle string theory should be able to answer.
Breakup blackout is when you're so upset and you've been crying so much that you basically black out for a couple of days. You wake up to mascara caked on your face and empty ice cream cartons everywhere, and your iTunes has, like, four new really bad romantic comedies you've rented. And your friends are texting you, and for three days you're in this black hole.
You carry in yourself all the obstacles necessary to make your realization perfect. If you discover a very black hole, a thick shadow, be sure there is somewhere in you a great light. It is up to you to know how to use the one to realize the other.
I'm a history geek and I love American history. It's so bizarre and so problematic and I love the many conundrums that it represents. You can go down so many black holes.
Historical science is not worse, more restricted, or less capable of achieving firm conclusions because experiment, prediction, and subsumption under invariant laws of nature do not represent its usual working methods. The sciences of history use a different mode of explanation, rooted in the comparative and observational richness in our data. We cannot see a past event directly, but science is usually based on inference, not unvarnished observation (you don't see electrons, gravity, or black holes either).
