So, physicists have announced the discovery of gravitational waves.

You’ve heard they’re “ripples in the fabric of spacetime”. You’ve heard they were a prediction of Albert Einstein’s general theory of relativity. You probably even know the waves that were detected were created when two massive black holes circled each other and violently collapsed. You can read all about the discovery here, and we’ve already answered a few questions here.

But we know you’re still brimming with questions! So here we have Dr Katie Mack, an astrophysicist from the University of Melbourne. She’s on hand to answer Everything You Wanted To Know About Gravitational Waves But Were Too Afraid To Ask.

No question is too basic! Hit us up in the comments and I’ll put them to Katie, who will do her best to bring you up to speed.
