On Thursday, the scientists at LIGO announced they’d officially found gravitational waves. This truly is a remarkable discovery, and confirms the final piece of Einstein’s general theory of relativity. Read more about the announcement, and what it means for science, here. And check out our gravitational waves explainer for more background on this scientific phenomenon.

The world was understandably excited about the breakthrough, including the estate of Einstein himself.

Our own Sophie Bushwick was at the announcement at Columbia University and caught this reaction from astrophysicist (and rap beef winner) Neil deGrasse Tyson.

It turns out Tyson had actually visited the LIGO facility about a month ago:
