Einstein@home

After two decades and more than half a billion dollars, LIGO, the world’s largest gravitational-wave observatory, is on the verge of a detection. Maybe. 3,520 more words

Why are complete compact-binary-coalescence waveforms so important for compact-object astrophysics?

The numerical relativity breakthrough in 2005 has provided waveforms of the gravitational wave signal emitted by a compact binary sources that describe the coalescence, the merger of the two compact objects and the ring-down of the newborn object. 273 more words

The Basics of Gravitational Waves

We all know that gravity is the attractive force between all massive bodies.  It’s why the apple that supposedly inspired his groundbreaking account of the fundamentals of physics hit Sir Isaac Newton on the head way back in the 17th century.   965 more words

A Trio For Catching A Wave.

A trio of black holes that are orbiting each other may help scientist in their search for gravitational waves.

The three closely orbiting supermassive black holes were discovered in a galaxy four billion light years away could help astronomers in the search for gravitational waves. 172 more words

Astronomers Hedge on Big Bang Detection Claim

By DENNIS OVERBYE

A group of astronomers who announced in March that they had detected space-time disturbances — gravity waves — from the beginning of the Big Bang repeated that claim Thursday but conceded that dust from the Milky Way galaxy might have interfered with their observations. 1,580 more words

Kaizo Mario, Tom Cruise, and the multiverse

A topic in quantum mechanics is the existence of a multiverse.  Recent experiments by the Background Imaging of Cosmic Extragalactic Polarisation (BICEP2) team seemed to lend credence to the existence of gravitational waves and a multiverse.   236 more words
