Looks like Old Man Universe might have changed over 13 billion or so years.
Specifically, the fine-structure constant may not be so constant.
Why is this important? If the constant is inconstant, then the strengthe of the electromagnetic force isn’t constant, either.
There had been some hints at this in the past few years, but with the question of whether the inconstancy was space-based or time-based. New evidence seems to not only support the inconstancy, but that it’s time-based. (Which makes more sense to me.)
Anyway, read all about it.
A skeptical leftist's, or post-capitalist's, or eco-socialist's blog, including skepticism about leftism (and related things under other labels), but even more about other issues of politics. Free of duopoly and minor party ties. Also, a skeptical look at Gnu Atheism, religion, social sciences, more.
Note: Labels can help describe people but should never be used to pin them to an anthill.
