At this summer’s Lindau Nobel Laureates meeting in Germany, the participating laureates and young researchers came from all over the world, but they had one thing in common: physics. The Nature Video team filmed five debates on issues that matter to the current generation of physicists. Is dark matter real? How can we solve the looming energy crisis? How is physics perceived by the public?

The result was a five-episode film series, as well as the trailer below, in which the filmmakers provide a preview of the discussions and disagreements that emerged.


For the first film in the series, the researchers focused on the Hubble Space Telescope, which has revealed numerous distant galaxies and planets orbiting other stars, deepening our knowledge of the universe. Nobel prizewinner John Mather works on Hubble’s replacement, the James Webb Space Telescope. He thinks we are in a golden age of astronomy. But the young researchers he met with at Lindau were not convinced. There are too many unanswered questions, they said. For example: what’s causing the accelerated expansion of the universe? Watch the film below to learn how Mather and fellow laureate Brian Schmidt, who first observed this expansion, handled the queries.
