Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is.

Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

In Zimbabwe in the 1980s, Mary Bassett witnessed the AIDS epidemic firsthand, and she helped set up a clinic to treat and educate local people about the deadly virus.

These same structural problems exist in the United States today, and as New York City's Health Commissioner, Bassett is using every chance she has to rally support for health equity and speak out against racism. "We don't have to have all the answers to call for change," she says. "We just need courage."

Uber didn't start out with grand ambitions to cut congestion and pollution. But as the company took off, co-founder Travis Kalanick wondered if there was a way to get people using Uber along the same routes to share rides, reducing costs and carbon footprint along the way. The result: uberPOOL, the company's carpooling service, which in its first eight months took 7.9 million miles off the roads and 1,400 metric tons of carbon dioxide out of the air in Los Angeles. Now, Kalanick says carpooling could work for commuters in the suburbs, too. "With the technology in our pockets today, and a little smart regulation," he says, "we can turn every car into a shared car, and we can reclaim our cities starting today."

More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical physicist Allan Adams, "making the universe explode in roiling waves of gravity." About 25 years ago, a group of scientists built a giant laser detector called LIGO to search for these kinds of waves, which had been predicted but never observed. In this mind-bending talk, Adams breaks down what happened when, in September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.
