What we learned from a golden moment in astronomy
Astronomers witnessed for the first time ever a rare collision of two dense neutron stars. The discovery began with an instrument called LIGO, which won this year’s Nobel Prize for its discovery of gravitational waves once predicted by Albert Einstein. Science correspondent Miles O’Brien joins Hari Sreenivasan to explain how the collision was detected and what it reveals about the universe.
