Scientists confirmed last year what Albert Einstein had predicted 100 years ago in his general theory of relativity. Physicists from the Laser Interferometer Gravitational-Wave Observatory detected gravitational waves, or ripples in spacetime, for the first time ever.
But what exactly does the research mean and how will it impact scientific discoveries in the future?
In the latest episode of The Huffington Post's "Talk Nerdy to Me," Caltech physics professor Rana Adhikari and host Karah Preiss explain how gravitational waves could one day help us hear the sounds of the Big Bang.
Check it out in the video above.
