Constants of nature such as c and h are the gods of modernity. As long as we haven't explained their origin, we are still far from understanding the laws of nature. More on this and related topics : https://www.amazon.com/dp/B0849ZXQB1 ... https://www.youtube.com/watch?v=Io0aoMhBAGM

Despite being variable, Mu is an message of nature we need to wonder about - in particular about its possible relation to the gravitational constant G.
