c change, see physics change



AUSTRALIA and South Africa are the shortlist for the Square Kilometer Array, a next-generation radio telescope to be completed around 2016. The Australian site in our western desert, is unique for its vast open space, stable politics, and isolation from radio sources. With all those antennas they will get excellent television reception.

Paul Davies, Tamara Davis, and Charles Linaweaver published a Letter to Nature about changing constants. A few words about Tamara Davis: She works on cosmology and the origins of life. She has been a ski instructor, gymnastics coach and surf lifeguard. Tamara was on Australia's Ultimate Frisbee Team and is an all-around exemplary woman.

As Mahndisa pointed out, someone named Duff tried to refute them. He was not accepted by Nature and forced to post his rebuttal on arxiv. How the world has changed! Not long ago people who said the constants are changing were completely ignored. I still hope that all ideas get heard so that you can decide which is best. Our turn on arxiv is coming soon. Today I'm at another conference and things are moving forward quickly.

Along with the new optical SALT telescope, South Africa would be a real force in astronomy if it got this project. Oh, but I do hope WA gets it! I went to a seminar in NZ about ideas to extend the array across Oz all the way to NZ.

HI Kea, and you are outstanding too. It is fascinating how Anzac could be dotted with antennas. I saw Primack in person on his book tour. His co-writer/spouse is a good speaker too. It is always nice to listen to other ideas.
