Talk about killing 2 birds with one stone.
A new paper out of physicists from NIST has managed to accomplish to very important task. The first is the use of an optical clock that is way more sensitive and accurate than the atomic clock. Secondly, due to the highly sensitive and accurate nature of the clock, they have shown essentially that the fine structure constant isn't changing over time.
I wonder if the J.K. Webb camp will be responding to this report....
