So, 2 billion years ago....

"Scientists have detected another burst of gravitational waves coming from the merger of two black holes."

Amazing stuff. So far they're all pretty similar in size; 35, 31, 30, 29, 25, 19, 14 and 7 solar masses, give or take. I can't wait for the first really big black hole merger.

"Gravitational waves just led us to the incredible origin of gold in the universe
LIGO kick-started an astronomical treasure hunt that ended with colliding neutron stars and gold."

"We are stardust. We are golden."
Even Hippies got there earlier.
This was 60's news.

What we have now is confirmation on the gravity wave spectrum.
