Vancouver hosts conference that will see physicists try to crack the theory of everything

Some of the world's brightest minds are gathering in Vancouver this week to try to solve a question that has baffled physicists for decades.

The two pillars of modern physics the theories of quantum mechanics and general relativity have been used respectively to describe how matter behaves, as well as space, time and gravity.

The problem is that the theories don't appear to be compatible, said Peter Galison, a professor in history of science and physics at Harvard University.

"These theories can't just harmoniously live in splendid isolation, one from the other. We know our account of the world is inadequate until we figure out how to make them play nicely together," he said in an interview after giving a talk on how black holes fit into the equation.

Galison is among several leading thinkers who arrived at the Quantum Gravity Conference, held at the Westin Bayshore Hotel,for the launch of a new global research collaborative known as the Quantum Gravity Institute in Vancouver.

While speakers at the conference are primarily scientists, including Nobel laureates Jim Peebles, Sir Roger Penrose and Kip Thorne, those behind the institute come from less likely fields.

The Quantum Gravity Society represents a group of business, technology and community leaders. Founding members include Frank Giustra of Fiore Group, Terry Hui of Concord Pacific, Paul Lee and Moe Kermani of Vanedge Capital and Markus Frind of Frind Estate Winery.

They are joined by physicists Penrose, Abhay Ashtekar, Philip Stamp, Bill Unruh and Birgitta Whaley.

'Why Vancouver?'

Lee,managing partner of Vanedge Capital and chair of the Quantum Gravity Institute, said during a panel discussion that he's been asked several times why Vancouver would host such an event or institute.

"Why Vancouver? Because we can," Lee said.

He told The Early Editionhost Stephen Quinnthat the potential of the work being done at the conference is limitless.

"I just look at what has happened over the last hundred years from quantum [mechanics] alone," Lee said.

"Who would imagine 100 years ago ... that suddenly, we would have these massive computing systems and the ability to do artificial intelligence? ... Or, you know, suddenly with medical imaging, we would be extending life spans of the average human by a quarter to a third.

"If we imagine even continued advances along those lines, you know, can we start solving aging?"

Lee said lofty ideas like time travel, interstellar space traversal and clean energy solutions were all on the table if a unified quantum gravity theory could be produced.

'A kick-off event for something much bigger'

Hui, president and CEO of Concord Pacific, who studied physics as part of his undergraduate degree, said organizing the conference and launching the institute felt like fulfilling a childhood dream.

"I left the field to pursue other things, you know," he said in an interview.

He said it was like never making the high school hockey team and now getting to hang out in the Canucks' locker room.

Hui said he saw his role as philanthropic, adding he believed it would benefit Vancouver economically.

For Galison, he said as a non-local and the founder of the Black Hole Initiative at Harvard, he's happy to see more interdisciplinary support for exploring some of the biggest questions in science.

He called the conference an interesting event for bringing together people in technology and venture capitalism with scientists from varied fields, addingthat the launch of the institutewasmeaningful.

"It's also a kick-off event for something much bigger and longer-lasting."

Lee said he hopes the conference and institute leads to more Canadian PhDs and scientists gaining valuable work and insight from the distinguished.

Answering the central question

As for the conference, Galison said it's an opportunity to explore where the theories overlap from different angles.

"One place they intersect is clearly at the beginning of the universe, early cosmology, because when energy is incredibly compressed, when you have enormous energy densities, you're at the limit where the bending of space and time creates so much energy that quantum effects come into play," he said.

The theory of quantum mechanics, introduced in the 1920s, entered a world already shaken by Albert Einstein's theory of relativity, which inspired responses not just from scientists but from poets and philosophers, he said.

"That these things are not compatible is really unnerving," Galison said.

Cracking the code for why isn't something that will happen in a moment, a week or a year, he added.

"There's a tremendous amount of work," he said. "It's more like building a cathedral than throwing up a bicycle shed."
