Brian Greene Quotes

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

The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.

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

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.

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

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.

There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.

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

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.

'Eternal inflation,' as it's called - the endless generation of new universes - may be a hyper-cosmic imperative. It seems that it must happen.

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.

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

Although we don't know what is outside our universe, astronomers still wonder. Several pictures of what there might be have been dreamed up. An interesting one, called multiverse, has lots of universes. Picture it as a foam of bubbles. Our universe would be one bubble, and we'd be surrounded by lots of other bubbles.

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.

You almost can't avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe.

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

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

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.

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

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.

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.

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science.

I think the universe is just so big that there has to be something else out there.

I believe we exist in a multiverse of universes.
