Gravitational waves could reveal the existence of quark matter
Two neutron stars smashing together may produce a form of matter not seen before. If that happens, simulations suggest there would be a signal in gravitational waves resulting from the collision
Gravitational waves could let us find tiny black holes devouring stars
A primordial black hole falling into a neutron star would sink to its centre and devour it in seconds, and we might be able to detect this process using gravitational waves
How a new kind of gravitational wave will reveal the early universe
With 90 detections now under our belt, gravitational waves are solving riddles about the evolution of galaxies and missing black holes – and they could soon give us a glimpse of dark matter
How you can get involved with the hunt for gravitational waves
In the search for high-energy astronomical events like black holes colliding, the data often has glitches. You can help weed those out using the Gravity Spy platform, says Layal Liverpool
