Ripples in the fabric of space-time

Albert Einstein predicted that gravitational waves would be produced in extremely violent events, such as collisions between two black holes. As these waves spread out, they compress and stretch space-time, producing ripples, whose presence could be detected by laser beams.

The physicist Lawrence Krauss sent out a tweet yesterday suggesting that the LIGO laboratory in the USA may have finally detected the ripples of gravitational waves.

We'll have to be patient for a while before learning whether or not this gigantic scientific information is true.
