The LIGO experiment is built to detect these things. They have two detectors and each detector is like, it's an L shaped thing. Each arm is four kilometers long. The first detection when it was detected, the length of that four kilometer arm changed in length by a thousandth the width of a proton. And this was a huge collision. This was like it was 1.3 billion light years away. So it was very far, but it was like the black holes were around 30 times as massive as sun. And so it was a pretty strong signal. Like if you actually looked at the data raw data, like you could see it, which is not usually the
