Sign of c Change
On the next block from Moscone Center was an art gallery with this encouraging sign. More people saw the presentation on "c change" than saw Ed Witten last month. As Peter Woit mentioned there, the world of particle physics has grown very small. Even the thousands of scientists at American Geophysical Union show little care for it. AGU was certainly more fun, with multiple parties every night. Tuesday at the Exploratorium museum the drinks had 3000-year old ice brought from Antarctica.
The biggest barrier to "c change" has been getting the word out. Most physicists won't take an opinion on something they have not been exposed to, and the mainstream press follows "dark energy" and the Concorde cosmology. The difficulty of publishing papers where c changes has not helped. Arxiv has become so corrupted that it serves little use. The Smithsonian/NASA Astrophysics Data System is far more thorough. Last week a large number of people, including NASA administrators, were very interested in a changing speed of light.
Happy 90th birthday to Sir Arthur Clarke!
