And really, none of that was a spoiler.
But this whole question of varying physical constants has been roiling the scientific community for years, especially the astrophysicists who really have their telescopic fingers on the cosmic pulse of the question. As all of us who ever took a high school sicen class know, physical constants are crucial to making a great many descriptive equations actually work. In Einstein’s E=mc2, the c is the constant, it’s the speed of light. Then there’s the Planck constant, Avogadro’s number, and on and on. But if those numbers suddenly turned out to be changing, then ...
