Neil deGrasse Tyson Quotes

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

An event horizon, or the point of no return, is only a byproduct of the bending of space. However, electricity and magnetism, by themselves, have no event horizon. It gets complicated, however, if a black hole has charge, and then this new solution does have an event horizon.

God abhors a naked singularity.

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.

Although almost every theoretical physicist agrees with my prediction that a black hole should glow like a hot body, it would be very difficult to verify experimentally because the temperature of a macroscopic black hole is so low.

My passion is to understand the non-linear dynamics of warped space-time, and the ideal venue for this is black-hole collisions.

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. There are however apparent horizons which persist for a period of time.

Einstein got most of the things right about black holes. I'm not an expert, I must admit.

So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.

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.

Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.

Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?

Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time not only affect but are also affected by everything that happens in the universe.

There are no black holes in the sense of regimes from which light can't escape to infinity.

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.

Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking.

Wormholes - if you don't have something threading through them to hold them open, the walls will basically collapse so fast that nothing can go through them.

My work on black holes was on the connection between black holes and elementary particles.

The whole idea of gravity curling up space, that is the epitome of what is going on in a black hole. I would've loved to have seen Einstein's face if he were presented with the data that we actually discovered such a thing, because he himself probably didn't believe in much of it.

The science behind Interstellar is interesting, because some of it is absolutely real astrophysics and orbital mechanics, some of it is theoretical physics, and some of it is completely Hollywood. When a science fiction movie is based on plausible science, it's really good.

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.

I'm a child myself, in the sense that I'm still looking. Children are fascinated by black holes and ask me questions. I find they soon get the idea if it is explained in nontechnical language.

I believe in black holes. I believe that as the universe empties into nothingness, past and future will smack together in the last swirl around the drain.

General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting together the probabilities of quantum mechanics with the certainty of general relativity, that's been the big challenge and that's why we have been excited about string theory, as it's one of the only approaches that can put it together.
