Finishing What Einstein Started
Last September, researchers detected an exceptionally weak signal that lasted for about a tenth of a second: the gentle chirp of a gravitational wave. This feat, which confirmed a prediction made by Albert Einstein 100 years ago, is worthy of the Nobel prize.

GÖTEBORG – A long time ago in a galaxy far, far away, two enormous black holes – each with a mass roughly 30 times larger than that of the sun – collided and merged, sending out a short, powerful blast of gravitational waves. The energy from the blast spread across the universe at the speed of light, diluting its power into the immense vastness of space.
