Only black holes of very low mass would emit a significant amount of radiation.
Aging bodies are fiscal black holes into which you can pour endless amounts of money.
I've seen children's eyes light up when I tell them about black holes and the Big Bang.
Black holes destroy any objects that happen to fall victim to their gravitational pull.
Einstein got most of the things right about black holes. I'm not an expert, I must admit.
My work on black holes was on the connection between black holes and elementary particles.
There are no black holes in the sense of regimes from which light can't escape to infinity.
Black holes can bang against space-time as mallets on a drum and have a very characteristic song.
Black holes do not emit light, so you visualize them through gravitational lensing - how they bend light from other objects.
I love looking at pictures of nebulas and reading articles about black holes and dark matter - I always tie it into spirituality.
We knew about black holes in other ways, and we knew about neutron stars - well, those are the two things that ultimately got seen.
Finding the first seed black holes could help reveal how the relation between black holes and their host galaxies evolved over time.
General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.
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.
We know about black holes and neutron stars, but we hope there are other phenomena we can see because of the gravitational waves they emit.
I'm an avid watcher of the Nat Geo channel, where I watch shows about how the planets are formed, and shows about moons, quasars, black holes.
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.
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.
Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.
The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
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.
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.
Evidence has been mounting for the key role that black holes play in the process of galaxy formation. But it now appears that they are likely the prima donnas of this space opera.
I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.
Observing gravitational waves would yield an enormous amount of information about the phenomena of strong-field gravity. If we could detect black holes collide, that would be amazing.
I once had an extraordinary experience with former prime minister Ted Heath. Both of his eyes, including the whites, turned jet black, and I seemed to be looking into two black holes.
My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.
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.
The size of the effect that we measured from the first event, the merging of two black holes, the actual size of the signal was about one thousandth the size of a proton, what it did to our apparatus.
There's a lot of cruelty going on all the time, and I'm not just talking about inter-human cruelty. I'm talking about whole species becoming extinct, asteroids hitting planets, black holes gobbling up stars.
For reasons probably related to the popular vision of Albert Einstein and, also, the threat posed by black holes in comic books and science fiction, our gravitational wave discoveries have had an amazing public impact.
I originally wanted to be an astronaut when I was a kid. Then I had this huge fear of black holes because my brother learned a bunch of stuff about it, and he's like, 'Oh, yeah, if you go into one you're never coming back.'
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.
It's hard for me to speculate about what motivates somebody like Stephen Hawking or Elon Musk to talk so extensively about AI. I'd have to guess that talking about black holes gets boring after awhile - it's a slowly developing topic.
The early universe was a dusty place, and the UV radiation from the hot, young black holes and stars would get enshrouded by dust, re-radiated, and scattered into red wavelengths like infra-red, causing these objects to remain obscured.
It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
The waves travel with the velocity of light and slightly squeeze and stretch space transverse to the direction of their motion. The first waves we measured came from the collision of two black holes each about 30 times the mass of our sun.
I would love to be remembered for ridding the world of disease, but my knowledge of science comes from episodes of 'Nova' and shows on the Discovery Channel. I don't think a superficial understanding of shark behavior and black holes can help cure diseases.
In elementary school, I read every single space book in the library about all the planets, about nebulas, about black holes. So for as long as I can remember, I've been just looking up at the stars and wondering what's out there and even what may be looking back at us.
I have suffered from migraines since childhood and have long been curious about my own aching head, my dizziness, my divine lifting feelings, my sparklers and black holes, and my single visual hallucination of a little pink man and a pink ox on the floor of my bedroom.
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.
The most attractive habitats for synthetic sentience might be the vicinities of exceptional sources of energy - for example black holes, or even the neighbourhoods of large stars, which routinely boil off the energy of ten thousand suns. These are the destinations they may seek.
If you wanted to travel backwards in time, you're out of luck. We have theories on how it might be possible to do so, but they all involve wormholes and black holes and other stuff that would probably kill you. If you want to travel forward in time, you just have to go really fast.
We've seen black holes, which is already wonderful. We also expect to see the merger of neutron stars, and that was a thing that actually gave this field a certain credibility when it was discovered that there were pairs of neutron stars in our galaxy, and people stopped laughing at us when that was found out.
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.
When the signal reached LIGO from a collision of two stellar black holes that occurred 1.3 billion years ago, the 1,000-scientist-strong LIGO Scientific Collaboration was able to both identify the candidate event within minutes and perform the detailed analysis that convincingly demonstrated that gravitational waves exist.
