Not really a question, but did you see the recent PBS Spacetime? They *might* have detected the gravity wave background, basically the sum of all gravitational waves, by observing pulsars across the galaxy. Pulsars are so accurate at timekeeping that the slightest discrepancy tells us something about the fluctuating distance between it and us.

Here's some pulsar porn...



The last one is spinning at 1/7 the speed of light, which would obviously create immense centrifugal forces. The fact this doesn't cause the star to disintegrate shows just how fucking ridiculous the gravity is.
