Is dark matter real? with George Smoot and Martinus Veltman

The morning after CERN announces the discovery of the Higgs particle, three young physicists sit down with Nobel prizewinners George Smoot and Martinus Veltman to digest the news. The students see it as another success for the standard model of particle physics. But Veltman, who helped to shape this model, is cynical. Moreover, Veltman contends that there is no such thing as dark matter. See how the shocked students and Smoot respond to Veltman's scepticism.
