...which reminds me: John Web an astronomer at UNSW, Sydney
has been raising hackles by noting that the absorption bands he saw
from bright quasars viewed at Keck, supposed to be due to absorption
by magnesium and iron are 1 ppm from the customarily assigned
frequencies. He CAN account for the shift by
postulating the alpha constant varies with time or place though....
Phys Rev Letters V82 v p884, and later confirmed at VLT (Chile) though this time fitted
by a different alpha value....

He is proposing a directionality to the value of that constant
(Reported NS 23 Oct 10 p33 Michael Brooks)

Perhaps he should be awarded a Nobel? :-)
