Inconstant Constants

This is what it looks like when experts disagree, or perhaps this is what it looks like when standing on the cusp of a paradigm shift. Bear in mind that this is no small disagreement, the argument is over what the facts are – maybe a given constant in physics isn’t so constant. But for us what is more intriguing is the question as to what the new knowledge will look like and what it means for how we will do things – or as is suggested in the article, we are about to “learn new physics.”
