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.
This is a slice of my philosophical, lay scientific, musical, religious skepticism, and poetic musings. (All poems are my own.) The science and philosophy side meet in my study of cognitive philosophy; Dan Dennett was the first serious influence on me, but I've moved beyond him. The poems are somewhat related, as many are on philosophical or psychological themes. That includes existentialism and questions of selfhood, death, and more. Nature and other poems will also show up here on occasion.
