When Einstein thought he was wrong but Feynman convinced physicists otherwise

Gravitational wave observations are set to expand the frontiers of our knowledge of the cosmos. Einstein’s solution Gravitational waves are clearly the future but the field itself has a humble history. They wrote a paper solving the Einstein equations without using any approximations and claimed that their results showed gravitational waves do not exist. The debate on whether gravitational waves could transmit energy was at the centre of the conference. Eventually, scientists announced the first direct detection of gravitational waves in 2016, 30 years after Feynman’s passing.
