Hi Guys

Prof. Ned Wright gives some good reasons to question the alpha-change data that the variable-speed-of-light idea relies on...

[just scroll down to the news bite "Variable Constants?"]

John Barrow and others have been working on variable-c theories of the Big Bang for a number of years. I think they hypothesise the major changes in c to be only during the electroweak unification "era" some microseconds after the Big Bang. This new data is only by a very small amount, if at all.

However we can achieve electroweak unification in current accelerators. As we progress into higher energy regimes odd c effects might become more obvious.

Another under discussed idea is tachyonic neutrinos - neutrinos of all types have been measured to have (potentially) negative masses for years, but only a few theorists have been game enough to make the natural suggestion - SOME neutrinos are tachyons.
