Brian Greene Quotes

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

When we understand string theory, we will know how the universe began. It won't have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.

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.

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

I like science fiction and physics, things like that. Planets being sucked into black holes, and the various vortexes that create possibility, and what happens on the other side of the black hole. To me it's the microcosmic study of the macrocosmic universe in man, and that's why I'm attracted to it.

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.

The universe never did make sense; I suspect it was built on government contract.

There may have been many big bangs, one of which created our universe. The other bangs created other universes.

People have contemplated the origin and evolution of the universe since before the time of Aristotle. Very recently, the era of speculation has given way to a time of science.

We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.

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.

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.

According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.

Heisenberg, Max Plank and Einstein, they all agreed that science could not solve the mystery of the universe.

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.

The beauty of science is to imagine more than we can prove. And string theory gives you a radically different interpretation of the universe.

We can trace things back to the earlier stages of the Big Bang, but we still don't know what banged and why it banged. That's a challenge for 21st-century science.

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.

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.

It now appears that the way the universe began can indeed be determined, using imaginary time.

As scientists, we track down all promising leads, and there's reason to suspect that our universe may be one of many - a single bubble in a huge bubble bath of other universes.

The idea that there could be other universes out there is really one that stretches the mind in a great way.

I was already writing about the idea of a 'multiverse' in the 1970s, though I might have called it the 'pluriverse.' How was I to know it would turn out to be the standard model? Actually, I consider myself an enlightenment fossil.

The limitless content of our universe might be only one instance of a large (and possibly infinite) number of other universes.
