Neil deGrasse Tyson Quotes

You fall into a black hole, and you are irretrievably gone from the universe. That finality has made it irresistible to writers.

If you go down through the horizon of a black hole, at the center you don't find a tunnel that leads you to some other place in the universe.

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.

I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.

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.

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!

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 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 main interest is the problem of the singularity. If we can't understand what happened at the singularity we came out of, then we don't seem to have any understanding of the laws of particle physics. I'd be very happy just to understand the last singularity and leave the other ones to future generations.

Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.

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?

About the 50th hour, I was going to start thinking about the edge of the universe. Is there an edge? Is this an envelope we're living inside of, or no, does it go onto infinity in both time and space? And there's nothing like swimming for 50 hours in the ocean that gets you thinking about things like this.

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.

In my third novel there is an actual black hole that swallows everything you love.

At the same time, new concepts and abstractions flow into the picture, taking up the task of describing the universe without reference to such time or space - abstractions for which our language lacks adequate terms.

If space is a fabric, then of course fabrics can have ripples, which we have now seen directly. But fabrics can also rip. Then the question is what happens when the fabric of space and time is ripped by a black hole?

When you're falling through space time has no meaning.

When you fall into a black hole you will be literally spaghettified.

Time can behave like another direction in space under extreme conditions.

And what we know, or think we know, about the universe of space and time is changing very quickly.

Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?'

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

A black hole really is an object with very rich structure, just like Earth has a rich structure of mountains, valleys, oceans, and so forth. Its warped space whirls around the central singularity like air in a tornado.

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that.

Fortunately, most things around the supermassive black hole are just going to go around it. They're going to orbit it. They don't actually get sucked in.
