The project became especially important during the era of gravitational-wave astronomy following the first direct detection of gravitational waves in 2015 by LIGO. Universe@Home simulations help scientists understand how binary black holes and neutron stars form and merge. | The project became especially important during the era of gravitational-wave astronomy following the first direct detection of gravitational waves in 2015 by LIGO.
