Physicists Say They Have Found the “Magic Number”

They have refined measurements of a number that is key to the workings of physics

Okay, first, it’s not literally “magic.” But some numbers are very important in the structure of our universe. In this case they are refining a very important but very strange number that links the forces of our universe: This pure number, with no units and dimensions, is key to the workings of the standard model of physics. Scientists were able to improve its precision 2.5 times or 81 parts per trillion (p.p.t.), determining the value of the constant to be α = 1/137.03599920611 (with the last two digits still being uncertain). Paul Ratner, “Scientists find the “magic number” that links forces of the universe” at BigThink The numbers that matter are not necessarily the ones we might expect. How about…
