Gravity waves

Detecting nuanced “glints” through spacetime could give us a view of dark matter and neutron stars.

The history and advancements of gravitational-wave astronomy are reviewed and the future of the field is discussed.

(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive neutron star in orbit with a companion white dwarf star puts competing theories of gravity to a test more stringent than any available before.

Scientists might be on track to revealing new facets of physics.

Orbiting neutron stars create gravity waves

LIGO scientists are set to announce discovery of gravitational waves.

When black holes merge strong gravitational waves are emitted. The graph shows a state-of-the-art comparison between waveforms of a black hole binary calculated according to two different techniques (top panel); the lower panel shows the final few cycles, including the merger of the two black holes.
