A Quote by Andrea M. Ghez

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.
Finding the first seed black holes could help reveal how the relation between black holes and their host galaxies evolved over time.
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.
My work on black holes was on the connection between black holes and elementary particles.
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.

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.
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.
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.
It had struck me that the world was full of holes, holes which you could fall into, never to be seen again. I couldn't understand the difference between disappearance and death. Both seemed the same to me, both left holes. Holes in your heart holes in your life.
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.
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.
When you think about it, there's no way to input things into a computer. It's all... the holes only go out, right? Like you can plug a keyboard or a mouse in but that's a trick because the computer thinks the inputs are outputs. That's a programmer trick, basically magic. The key to the future is to make holes that go in too.
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.
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.
