How To Detect Gravitational Waves

In September 2015, the LIGO observatory detected gravitational waves! Now we can observe the universe in an entirely new way.

When Einstein published his theory of general relativity a century ago, he really made some waves. Or, at least, he predicted them.

We're talking gravitational waves.

Einstein was pretty sure it would be impossible to ever directly detect any gravitational wave. But in September 2015, the LIGO observatory did it!

In this episode, we dive into spacetime and break down exactly how they did it and ask the bigger question, what does this discovery mean?
