Thanks for that Stuart.  Indeed this is the greatest time of all to be living if one is into astronomy.  The astonished Webb images, the completely mind-blowing LIGO results, oh my goodness.  Regarding the LIGO results: I just can't imagine how the heavens there are still sooooo many of those mergers this long after the big bang.  

I have never been so wrong as I was about that prediction, but I am in good company.  (Well, I was wronger about Tesla, passing up multiple opportunities to buy at 2 bucks a share.)  A lot of us read the pros and cons and pretty much uniformly guessed we would be dang lucky if there was even one event in the next century.  I estimated 5% chance of a detectable merger in my lifetime.  We have had 22 strong mergers in the past 6 years with the device up and running only a little less than half the time, and a long list of candidate events.

I am still baffled with regard to how there could still be so many of them.  Where does all the angular momentum go?  Stuart is that blowing your mind too?  I remember spending several weeks pondering that and doing calculations, got nowhere at all, not a cm closer to understanding.
