The recent merger of two neutron stars produced both visible light and gravitational waves, and that lets us determine just how fast the universe is expanding.
The latest detection of gravitational waves shows the power of gravitational astronomy, and lets us study aspects of quantum gravity.
Will Earth eventually spiral into the Sun due to gravitational waves?
Atomic clocks could be used to observe gravitational waves in a new way.
The second detection of a black hole merger confirms the success of gravitational wave astronomy.
LISA Pathfinder has made its first successful test of gravitational wave astronomy.
There are lots of efforts to derive a quantum theory of gravity. One of these is known as conformal gravity.
A new black hole model will not “break” relativity.
While there is a small chance this is simply due to chance, it looks like the gamma ray burst was triggered by the merging black holes.
