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.
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.
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.
One of the key differences between galaxies with super massive black holes is whether or not the black holes are lit up, because they are basically bingeing on a lot of material in its surroundings.
My work on black holes was on the connection between black holes and elementary particles.
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.
My work indicated that if we consider smaller and smaller black holes, at some stage, the properties of black holes become indistinguishable from those of elementary particles.
There are no black holes in the sense of regimes from which light can't escape to infinity.
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.
Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.
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 we're dealing with are black holes as described by general relativity.
Eyes as black and as shiny as chips of obsidian stared back into his. They were eyes like black holes, letting nothing out, not even information.
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.
Paintings are seldom guilty and often framed for crimes they did not commit. Some cover holes-holes in walls, holes in lives. Some make holes-in wallets, holes in hearts...in negative space.
That's all that counts. People being sorry. Makes you feel better; gives you a sense of dignity, and that's all that's important; a sense of dignity. And it doesn't matter if you don't care or not, either. You got to have a sense of dignity, even if you don't care, 'cause, if you don't have that, civilization's doomed.
