Gravitational waves, ripples through the fabric of space-time predicted by Albert Einstein a century ago, have been detected for a third time.
Scientists first detected the shudders in space-time last year and the discovery was hailed the ‘biggest scientific breakthrough of the century’.
Now, for the third time, researchers have detected the warping of space-time caused by a collision of two black holes colliding three billion light-years away – providing a new window on our universe.
WHAT ARE GRAVITATIONAL WAVES?
Scientists view the the universe as being made up of a ‘fabric of space-time’.
This corresponds to Einstein’s General Theory of Relativity, published in 1916.
Objects in the universe bend this fabric, and more massive objects bend it more.
Gravitational waves are considered ripples in this fabric.
