Idea of possible gravitational waves won Nobel 24 years ago
The 1993 Nobel Prize in Physics was awarded to two Princeton researchers for the discovery of binary pulsars, rotating fuel-exhausted neutron stars. The duo then theorised the two-star system should lose energy by emitting gravitational waves, as per Einstein's prediction in 1916. However, the first direct detection was not made until 2015, scientists behind which won the 2017 Physics Nobel.
