A Quote by Lee Smolin

General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.

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.

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.

Rainer Weiss

We cannot explain the phenomenon of gravitational lensing without general relativity, and this is where MOND spectacularly fails.

Priyamvada Natarajan

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.

Paul Davies

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

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.

Andrea M. Ghez

Black holes destroy any objects that happen to fall victim to their gravitational pull.

Kevin McCarthy

Combining quantum entanglement with wormholes yields mind boggling results about black holes. But I don't trust them until we have a theory of everything which can combine quantum effects with general relativity. i.e. we need to have a full blown string theory resolve this sticky question.

Michio Kaku

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!

Andrea M. Ghez

When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.

Albert Einstein

[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did

Albert Einstein

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

Priyamvada Natarajan

When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.

Brian Greene

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.

Andrea M. Ghez

Black holes do not emit light, so you visualize them through gravitational lensing - how they bend light from other objects.
