For the past 90 years, the predictions laid out Einstein's general theory of relativity have continued to be confirmed by experimental science. The last hold out is gravitational waves - the idea that certain gravitational events cause actual ripples in Spacetime. The problem is that the effects are almost beyond microscopic, so they are incredibly hard to detect. But have scientist done it? Have gravitational waves finally been directly observed??? Watch the episode to find out.
