INT.  PACKED AUDITORIUM—THE RUBIN MUSEUM OF ART (New York City)

CHARLIE KAUFMAN, middle-aged screenwriter, and BRIAN GREENE, middle-aged physicist, walk onto the stage.  They shake hands.  The audience applauds.  The two men are seated.  They will discourse about the nature of time.

TIM McHENRY (PROGRAM DIRECTOR EXTRAORDINAIRE)

When did time first appear in your thoughts?

For both men, it naturally follows from the idea of death.  Indeed, KAUFMAN and GREENE are like-minded, both deep and brilliant.  Most of the words (numerous like galaxies) are spoken by GREENE, to the rapt and eager attention of the audience.  After all, he is describing, with lucid explanations, fathomable analogies, and expressive hands, what seems to be a holy grail of human understanding: fundamental, objective truth about the universe.  “I am in awe of your knowledge,” admits KAUFMAN humbly.

KAUFMAN, at once funny and serious, asks intelligent and informed questions, demonstrating an impressive understanding of difficult concepts.  “You said it better,” GREENE grants once.  The display on-stage at the Rubin is one of gifted intellects, whose coming together is for the genuine benefit of the audience.  The following, from the March 6 Brainwave event, would be the key moments in the film:

QUESTION ONE:  WHAT IS TIME?

Mr. Greene defined time as: “the mechanism by which you can notice change.”  He suggested that it may be a derivative idea, an emergent property, not elemental to the first equations of physics.  The equations certainly do not distinguish between past and future.  In fact, all moments of time are in existence.  We can imagine an expanse of space before our eyes, but not time.  This is merely a limit of our representative imagination.  It is just as “real,” even “material,” as this computer, or the Pacific Ocean.

Why do we experience a sequence—a passage, a flow—of time?  Mr. Greene offers an evolutionary explanation.  Establishment of a now (including an imprinted past in the form of memory) distinct from a future leads to predicting and anticipating, planning and striving, brain-initiated functions that encourage acquisition of energy until the replication of DNA, and thus survival in nature.  Mr. Greene insists that there is no mathematical distinction between present and future.  There is no unique NOW.  (“And is that, is that what they’re thinking these days?” said Mr. Kaufman, mind blown, to a laugh).

Words ultimately fail here– although Mr. Kaufman’s, writer that he is, were often perfectly selected.  “Now is a function of a brain.  If there is no brain, I think there is no now.  It just is, whatever that means.”  (“Do you guys . . . smoke a lot of pot?” the novelist and Kaufman-collaborator Susan Orlean humorously asked during the question period).  Let it be known, too, that quantum physics complicates this picture.

QUESTION TWO:  HOW CAN WE KNOW?

Mr. Kaufman more than once pointed out the limitations of our brain, of its scientific method, its theories, its equations, and even math itself.  Mr. Greene pointed out that some believe that math exists independent of the human brain.  Some even believe that the world is a mathematical structure, and our reality is draped over it.  Mr. Greene’s own opinion has changed over the course of his career.

“This room is not this room, it’s our interpretation of the light waves,” reminds Mr. Kaufman.  This line of thought (“It’s all I’ve got,” revealed Mr. Kaufman, trying his hardest to do the duty of skepticism) amounts to the only valid caveat— subjectivity— to the accepted discoveries of physics.  But Mr. Kaufman said he believed that human beings can make objective progress in their understanding.  Mr. Greene shared his doubt that we can ever know everything.

QUESTION THREE:  WHY IS THERE SOMETHING RATHER THAN NOTHING?

The principles of quantum physics suggest that “nothing” is coaxed into what’s called a “quantum fluctuation,” producing positive energy that then evolved into the universe.  The “negative energy” perhaps evolved into “something else.”  This is simply a vague idea.  Question three remains the ultimate philosophical question.  Will any human being ever know the answer to this question?  (“Brian!?” Mr. Kaufman said, exasperated, to Mr. Greene).  Note: there may be multiple universes, each its own ineffable, immeasurable “something.”

QUESTION FOUR:  THE AWKWARD QUESTION

Namely: is there really such a thing as “free will?”  Nothing in the laws of physics points to free will, said Mr. Greene.  Therefore, like time, it is “a useful illusion.”

In the final line of the film, BRIAN GREENE says: “We are a bag of particles governed by the laws of physics.  And that’s it.”

    Although I know the interview only existed because you were there to report it to me and I am able to read about it at this computer as virtual as it is, I loved your account of the conversation that might have taken place at the Rubin between Brian Greene and Charlie Kaufman

      Wow Sherri, Things are hopping over there in the suitdo. What fun. I’m doing some sewing too. Inspired by a trip I took to Sisters, OR. The Stitching Post fabric shop is there and they put on a big quilt show every July. I just missed it. I bought a bunch of fabric though and am now happily sewings strips together and making pillows for my front porch rocking chairs. I’m leaving for Penland on Wednesday. I wish I was going to your workshop again it was such a great thing for me.xo diane

    • You’ve really captured all the essentials in this subject area, haven’t you?

    • These pieces really set a standard in the industry.

    Thanks for the kind words DW! I’ll think of you when I write.
