I was wrong. Simply wrong.




Tomaz, how do you know you were simply wrong?  Can you show me the equations you now use to prove yourself wrong?


I can’t.  I am looking thru my green notebooks where I calculated this stuff tragically many years ago, and realizing I didn’t understand the weirdness of General Relativity then, and I don’t understand it now.  I am durn sure not ready to second-guess Anders, but I am older than that fine young man, and recall the discussions among the astronomy geeks in the 80s.


Somehow I convinced myself then that GW pulses even a million LY distant or even closer would be a nothing-burger.  I can’t follow my reasoning however.  I was smarter back then in some ways.  Dumber in others.  Now I can’t tell which is which.


Have we some astrophysics hipsters among us please?  Can you offer us the equations you guys are using these days?
