Their source characteristics, explosion, and duration is also controlled by G. The fact they are recognizeable to a z of about 5 says you are barking up the wrong tree. ... > The decrease of G with cosmic time is (in the continuous > approximation) given by the equation: > > (1) (1/G)*(dG/dT) = - (1/3)*(1/T) (dG/dT is the time > derivative) The value of G has been constant to a very high order (something like 1 part in 10^8) over the last 2.2 billion years, with tidal rhythmites. I'd bet that G isn't as constant or fundamental as we'd hope, but I would guess that it averages to a local "constant". David A. Smith
