This week’s science picture
Ooh, gravitational waves!
Two black holes merged billions of light years away, causing a ripple in the fabric of spacetime big enough to be measured by scientists at the LIGO Collaboration. The results provide further support for Einstein’s theory of general relativity.
The 4km long interferometers at LIGO simultaneously detected a disturbance in their lasers signifying the passing of a massive gravitational wave through the Earth. The measurements suggest the black hole collision released a wave og gravitational energy equal to three times the mass of the sun.
Prof Danzmann (a leading European scientist at LIGO) praised the finding as one of the most important discoveries since the Higgs boson and on par with the discovery of the double helix.
Detecting the waves opens up the Universe to completely new investigations leading to a new era of astronomy.
