Gravitational Wave Astronomy: When Stars Die, New Sciences Are Born

Get ready for a decade of scientific revelations. Thanks to gravity waves, we have a completely new way to explore the universe.

Alex Filippenko is a Hertz Foundation Fellow and recipient of the prestigious Hertz Foundation Grant for graduate study in the applications of the physical, biological and engineering sciences. When the discovery of gravitational waves was announced in February 2016, Filippenko was awed. The researchers at LIGO (Laser Interferometer Gravitational-Wave Observatory) managed to prove a key prediction of Einstein's general theory of relativity: his theory of gravity. Here, Filippenko explains the mind-boggling way they did it, and the scope of discoveries that this hyper-precise technology will reveal to us over the next decade. With the support of the Fannie and John Hertz Foundation, Filippenko pursued a PhD in astronomy at the California Institute of Technology.
