Neil deGrasse Tyson Quotes

You go, dark energy! Go on, dark matter. They don't understand you, dark matter. They don't get you.

You're entitled to say, if you're so smart, why don't you tell me what that dark matter is? And I'll have to confess I don't know.

It is an embarrassment that the dominant forms of matter in the universe remain hypothetical.

Dark matter has a gravitation effect on other objects. You can't see it, you can't feel it, but you can watch something being pulled in its direction.

In terms of the most astonishing fact about which we know nothing, there is dark matter and dark energy. We don't know what either of them is. Everything we know and love about the universe and all the laws of physics as they apply, apply to four percent of the universe. That's stunning.

From a scientific point of view, our mission is to seek answers to the fundamental questions about the universe. Many are open - we don't know about dark matter, which accounts for a quarter of the universe's matter, nor do we know why there's antimatter.

Dark matter is interesting. Basically, the universe is heavier than it should be. There's whole swathes of stuff we can't account for.

The idea of combining the physics of modern particle theory with cosmology was very young when I started working on cosmology.

Everything we know about the universe is studied by using telescopes or other instruments that look at visible light, infrared, ultraviolet or X-ray - different wavelengths of electromagnetic interactions. Only 4 percent of what's in the universe gives off electromagnetic radiation, so we don't have any handle on the rest.

I am deeply impressed with the way dark matter has explained cosmological observations.

Dark matter is particularly intriguing because it's some kind of particle - that's for sure.

All the particles that we are made of only account for about four per cent of the cosmic inventory.

As an astrophysicist, my research work involves mapping dark matter, the elusive substance that accounts for about a quarter of our universe.

Dark matter is everywhere. In this room. Everywhere.

85 percent of the gravity of the universe has a point of origin about which we know nothing.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

All the stuff we've ever seen in the laboratory, all the kinds of particles and matter and energy, that only makes up 5 percent of our universe.

We account for one-sixth of the forces of gravity we see in the universe. There is no known objects accounting for most of the effective gravity in the universe. Something is making stuff move that is not anything we have ever touched.

For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

We know there must be new physics. For example, we cannot explain what dark matter is.

If you're puzzled by what dark energy is, you're in good company.

If dark matter and dark energy are 95 percent of everything, shouldn't we all be asking questions about that? What does that look like?

Most gravity has no known origin. Is it some exotic particle? Nobody knows. Is dark energy responsible for expansion of the universe? Nobody knows.

Our galaxy, the Milky Way, is one of 50 or 100 billion other galaxies in the universe. And with every step, every window that modern astrophysics has opened to our mind, the person who wants to feel like they're the center of everything ends up shrinking.

We have a remarkably complete picture in many ways - and it could be that we're not accounting for something that's almost three-quarters of the entire universe.
