It has become conventional to interpret the Planck scale MP as a fundamental scale of nature, indeed as the scale at which quantum gravitational effects become important. However, Newton’s constant G (G 1⁄4 M 2 P in natural units @ 1⁄4 c 1⁄4 1) is measured in very low-energy experiments, and its connection to physics at short distances—in particular, quantum gravity—is tenuous, as we explore in this paper. If the strength of gravitational interactions [henceforth, Gð Þ] is scale dependent, the… CONTINUE READING
