Listening to the universe with gravitational waves


  • Daniel Holz ⋅ US University of Chicago, USA


We are now able to detect gravitational waves, which are ripples in the fabric of spacetime. Gravitational waves provide an entirely new way to learn about our universe. We have heard collisions of neutron stars and black holes in distant galaxies, and from these have learned about how stars live and die, where gold and platinum come from, and are helping to measure the age and composition of the universe.
