Sean M. Carroll Quotes

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.

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.

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.

We have to wonder, if there is a multiverse, in some other patch of that multiverse are there creatures?

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.

String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.

I can't even begin to grasp concepts like the multiverse.

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.

Sometime in the future, science will be able to create realities that we can't even begin to imagine. As we evolve, we'll be able to construct other information systems that correspond to other realities, universes based on logic completely different from ours and not based on space and time.

Maybe it's due to my west coast liberal upbringing, but, the idea of parallel universes doesn't strike me as being too far out there.

I've always been fascinated by quantum physics and the possibility of alternate realities.

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

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.

I'm a big believer in quantum physics, which says that the universe is more incredible and mysterious than any of us can imagine, which is my way of saying, 'Anything is possible, including angels.'

The great thing about a parallel-dimensions story is that you can literally never run out of plot.

There are infinite worlds both like and unlike this world of ours. For the atoms being infinite in number... are borne on far out into space.

Every second the Universe divides into possibilities and most of those possibilities never happen. It is not a uni-verse -- there is more than one reading. The story won't stop, can't stop, it goes on telling itself, waiting for an intervention that changes what will happen next.

There were timelines branching and branching, a mega-universe of universes, millions more every minute. Billions? Trillions? The universe split every time someone made a decision. Split, so that every decision ever made could go both ways. Every choice made by every man, woman, and child was reversed in the universe next door.

Go then, there are other worlds than these.

Extra dimensional theories are sometimes considered science fiction with equations. I think that's a wrong attitude. I think extra dimensions are with us, they are with us to stay, and they entered physics a long time ago. They are not going to go away.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

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.

Technologies that may be realized in centuries or millennium include: warp drive, traveling faster than the speed of light, parallel universes; are there other parallel dimensions and parallel realities? Time travel that we mentioned and going to the stars.
