Nobel prizes: Breakthroughs

It is the kind of question only the most brilliant scientists ask, the kind of question that in 1916 allowed Albert Einstein to theorise the existence of gravitational waves — ripples in the fabric of space-time like a wrinkle on a bed sheet.
The 2017 Nobel Prize in Physics, awarded to three Americans who have proven Einstein’s theory, is testament to the monumental feats of engineering, human ingenuity and, most of all, patience that made the breakthrough possible.
