Scientists have used computer models to predict the size of minuscule deformations, or mountains, on the surfaces of neutron stars, which are responsible for causing gravitational waves as they spin.
Gravitational waves are ripples in space-time created by the interaction of massive objects in space, such as black holes and neutron stars. Their existence was first predicted by Albert Einstein in his 1916 paper describing his theory of general relativity. In 2015, scientists made the first detection of gravitational waves, observing ripples from the collision of two black holes. The discovery won astrophysicists Kip Thorne, Barry Baris and Rainer Weiss the 2017 Nobel Prize for Physics. Subsequent observations have also detected gravitational waves from colliding neutron stars. Learn more about gravitational waves here.
The earliest and most momentous epoch in the history of the universe released a flood of gravitational waves, tiny ripples in the fabric of space-time.
Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence.
After more than four years of exploring a menagerie of cosmic happenings through gravitational waves, scientists have finally spotted the third expected variety of collision — twice.
Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.
