Gravitational waves 404!

“This time, scientists are excited to find nothing.

In results announced today, a huge physics experiment built to detect gravitational waves has yet to find any.

Rather than be disappointed by the null findings, physicists say the results were expected, and in fact help them narrow down possibilities for what the universe was like just after it was born.

The Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO) is a set of instruments in Louisiana and Washington built to search for evidence of gravitational waves, which are theoretical ripples in space-time thought to be caused by the acceleration of mass. No one has yet directly detected these waves, though they are predicted by Einstein’s theory of General Relativity, and are widely thought to permeate our universe.”
