We've known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make up about 70 percent of the universe.
We know there is gravity because apples fall from trees. We can observe gravity in daily life. If we could throw an apple to the edge of the universe, we would observe it accelerating.
Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.
I think the mystery of what's out there in the universe is just very compelling.
Einstein wrestled with a problem back before we even knew the universe was expanding, and he was looking for a way to keep the universe from collapsing. And so he discovered, in his theory of gravity, something like this dark energy - he called it a cosmological constant - could play this role, pushing things away.
That aesthetic of the Star Wars universe: the do-it-yourself, hotrod ethic that George Lucas exported from his childhood, is exactly the same kind of soul behind what we do and build for the show. It may not look pretty, but it gets the job done.
The idea of an ordered and elegant universe is a lovely one. One worth clinging to. But you don't need religion to appreciate the ordered existence. It's not just an idea, it's reality. We're discovering the hidden orders of the universe every day.
Poetry is above all a concentration of the power of language, which is the power of our ultimate relationship to everything in the universe.
I'm fanatical about movies: African, European, Viking, Roman. I got into witchcraft and magic from watching 'Bewitched' and 'The Wizard of Oz,' which shows in some of my outfits. I dress to reflect the whole spectrum of the universe.
The universe lies before you on the floor, in the air, in the mysterious bodies of your dancers, in your mind. From this voyage no one returns poor or weary.
