Theoretical physicist and Nobel laureate Kip Thorne combines a love of art and science in his work, and he shared that passion with an audience that packed Memorial Hall on Thursday evening.
Thorne discussed “My Romance with the Warped Side of the Universe: From Black Holes and Wormholes to Time Travel and Gravitational Waves,” as the 2018-19 Frey Foundation Distinguished Visiting Professor in the College of Arts & Sciences. His talk marked the 25th anniversary of the Frey lecture.
The Frey Professorship is one of the highest honors bestowed by the College to distinguished public leaders. Alumnus David Gardner Frey chairs the Frey Foundation.
Thorne, a professor of theoretical physics emeritus at Caltech, was awarded the Nobel Prize in Physics in 2017, along with Rainer Weiss and Barry C. Barish, for their contributions to the observation of gravitational waves. This observation confirmed a key piece of Einstein’s Theory of General Relativity. He was also an executive producer on Christopher Nolan’s 2014 film “Interstellar,” where he served as a scientific consultant.
“The venue for ‘Interstellar’ is the warped side of the universe — black holes, wormholes, singularities and gravitational waves,” said Thorne, who peppered his talk with images and clips from the movie. “We built these phenomena, with the exception of gravitational waves, in the movie. And I wrote a book, ‘The Science of Interstellar.’”
Before Thorne spoke, actors from PlayMakers Repertory Company portraying Galileo and his friend Sagredo re-enacted a scene from the theater company’s production of “Life of Galileo,” which opens Feb. 27.
Interim Chancellor Kevin M. Guskiewicz said that at UNC-Chapel Hill the richest kinds of collaborations and insights happen when people from diverse disciplines come together and that Thorne was a great example of that.
“He has spent the last part of his career bridging the divide between the sciences and the arts, making abstract scientific concepts understandable to those of us who do not have a background in physics or astronomy,” Guskiewicz said.
Thorne shared the excitement of making the “big discovery” that led to the Nobel Prize. He said his research group “wanted to do for gravitational waves what Galileo did for electromagnetic waves.”
Scientists working with LIGO — Laser Interferometer Gravitational Wave Observatory — made the breakthrough discovery of gravitational waves arriving at Earth from the distant universe on Sept. 14, 2015.
More than a billion years ago, he said, two black holes circled each other and crashed together to produce a burst gravitational waves.
“The power output was 50 times larger than the total power output of all the stars in the universe put together,” Thorne said. “It was the biggest, most powerful explosion except for the Big Bang, the birth of the universe itself.”
These days, Thorne said he spends more time nurturing his artistic side. He is working on a book, “The Warped Side of the Universe,” with artist Lia Halloran that will feature his poetry.
“I was an astrophysicist for 50 years, and I decided I wanted to do something different for the next 50 years,” Thorne said.
Guskiewicz, along with former Chancellor Carol L. Folt, worked to bring Thorne to Chapel Hill. Thorne, Folt said, is an example of what can be achieved when creativity and hard work fuse to push the boundaries of what is known today.
“Perhaps Stephen Hawking, Dr. Thorne’s longtime friend and colleague, was thinking about him when he said, ‘Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious,’” Folt said.
