A Quote by Andrea M. Ghez

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.

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!

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.

Brian Greene

Proof of the black hole is a tremendous amount of mass inside a very small volume. There's 4 million times the mass of our sun within a region that's comparable to the size of our solar system.

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.

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?'

Andrea M. Ghez

Only black holes of very low mass would emit a significant amount of radiation.

Stephen Hawking

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.

Michio Kaku

Finding the first seed black holes could help reveal how the relation between black holes and their host galaxies evolved over time.

Priyamvada Natarajan

I like science fiction and physics, things like that. Planets being sucked into black holes, and the various vortexes that create possibility, and what happens on the other side of the black hole. To me it's the microcosmic study of the macrocosmic universe in man, and that's why I'm attracted to it.

Wesley Snipes

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.

Ashoke Sen

The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And you can do that with the motions of stars. The way the star moves around the center of the galaxy is very much like the way the planets orbit the sun.

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.

Ashoke Sen

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.
