Brian Greene Quotes

Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

They say the universe is expanding. That should help with the traffic.

I wouldn't say that 'The Fabric of the Cosmos' is a book on cosmology. Cosmology certainly plays a big part, but the major theme is our ever-evolving understanding of space and time, and what it all means for our sense of reality.

Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

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.

There is nothing bigger or older than the universe.

I'm a cosmologist. All I do is cosmology.

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

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

Space is almost infinite. As a matter of fact, we think it is infinite.

It was only about sixty years ago that the expansion of the universe was first observed.

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.

It's everywhere, really. It's between the galaxies. It is in this room. We believe that everywhere that you have space, empty space, that you cannot avoid having some of this dark energy.

While I'm a big fan of science fiction, especially as rendered in expensive Hollywood blockbusters, it's the real universe that calls to me.

Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.

The main reason why people should care about research in fundamental physics is the same reason they care about astronomy and cosmology. People, children, want to know what we're made out of, how it works, and why the universe is the way it is.

There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.

The universe is a great mystery.

Modern science cannot explain why the laws of physics are exactly balanced for animal life to exist.

One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.

I've always really been into science, and in the last five years I've gotten into theoretical physics and the origins of the universe.

Dark energy is perhaps the biggest mystery in physics.

What really made me think about space and begin to think about ways to use it was Einstein's statement that there are no fixed points in space. Everything in the universe is moving all the time.
