Discovery of the antigraviton verified by the rotation curve of NGC 6503

Abstract

Using special relativity theory, it was discovered that to each graviton, there coexists its antiparticle, an antigraviton. Building on this discovery and quantum theory, a new quantum gravity theory (QGT) was invented, providing equations of the gravitational potential, the graviton wavelength, and the circular speed, without the dark matter hypothesis (DMH). According to this QGT, the gravitational scale-length of a spiral galaxy depends on its mass distribution, being approximately equal to 1.5708 times the radius of its “radial center of mass”. Also Newtonian gravity theory (NGT) is of limited validity: if the radius is less than the gravitational scale-length, NGT is exact; but if the radius is greater than the gravitational scale-length, it becomes inadequate, and is surpassed by QGT. When the theoretical rotation curve was compared with the rotation curve of the galaxy NGC6503, the QGT was verified within the rms error of the measured rotation speeds, 3.0 percent. It was also demonstrated how two formulas of general relativity theory (Schwarzschild metric, gravitational time dilation) may be revised by the QGT, and thus be upgraded to formulas of quantum general relativity theory. It is suggested the so-called “dark matter” problem can be solved by discarding the DMH and adopting our new QGT.
