Quantum Gravity and String Theory

   

Discovery of Quantum Gravity

Authors: Gene H Barbee

Gravity is still an active research area for scientists even though English mathematician Isaac Newton published his work entitled Principia in 1867. For the last twenty years or so some of the best theorists have been working on quantum gravity. There is a basic disconnect at the heart of gravity. The problem is that although Isaac’s equations are correct they describe large scale behavior of objects. Einstein’s general theory of relativity is the modern theory of gravity but again, it describes large scale behavior of objects following paths curved by mass. This leaves small scale (quantum scale) gravity a subject of research. In the author’s opinion, a solution to the problem was delayed by general acceptance of an old relationship between fundamental constants. Literature states that the gravitational constant (G) originates at the Planck scale. The Planck length (Compton wavelength) L= (h*G/C^3)^0.5 = 1.61e-35 meters where h is Planck’s reduced constant (H/2pi) = 6.58e-22 MeV-Sec and C is of course the speed of light. The energy associated with the Planck length is 1.2e22 MeV. This energy is far greater than the energy of a proton and the Planck length is incredibly small. Many physicists are reluctant to give up the equation that contains G, h and C in what appears to be a defining relationship. Theorists are exploring alternatives like string theory in search of unification but have failed to gain acceptance of a new theory describing the origin of the gravitational constant.
