Forces to Reckon with: Does Gravity Muck Up Electromagnetism?: Scientific American: "In 2006 Sean P. Robinson and Frank Wil czek of the Massachusetts Institute of Technology applied the effective theory to see whether gravity changes the way forces vary in strength with scale. If gravity doesn't interfere, electromagnetism should become equal in strength to the nuclear forces at one scale and to gravity at a different scale. Robinson and Wilczek conjectured that gravity saps the strength of the other forces and causes them all to match up at the same scale. The idea didn’t pan out but did get people thinking about how the forces mess with one another."
