The results confirm the approximate radius of the Sun’s inner core 1,220,000 meters and gravity at its surface, 274 m/s2. The Sun’s rotating electromagnetic field radiates to Pluto and beyond. Like gravity, the near magnetic field of a sphere weakens with the inverse square of the distance. The Sun is a constant speed and constant acceleration machine. Like a set speed Ferris wheel, the orbital speed of planets is faster nearer to the Sun and reduces as the distance increases. The Standard Gravitation Parameter (m3/s2) is analogous to accelerating cubic volume (m3/s2) of the solar system. The planets are being pushed away by a centrifugal force from the constant acceleration of the Sun’s magnetic field, while at the same time being pulled in by the force of the Sun’s centripetal acceleration. Planetary orbits are the result of this balancing of forces. Gravity is a centripetal acceleration derived from a rotating electromagnetic field. Gravity is derived from an electromagnetic field which means it is not a force. There are only three forces in the universe: electromagnetic, strong nuclear and weak nuclear.展开更多

Clear Shubnikov-de Haas oscil- lations were resolved at relatively low magnetic field around 4 T, revealing a quasi-2D Fermi surface. We observed a development of quantized plateaus in Hall resistance （Rxy） at high pulsed fields up to 60 T. Due to the strong 2D confine- ment and layered properties of the samples, we interpreted the observation as bulk quantum Hall effect that is contributed by the parallel 2D conduction channels. Moreover, the spin degeneracy was lifted leading to Landau level splitting. The presence of anisotropic g factor and the formation of the oscillation beating pattern reveal a strong spin-orbit interaction in the SrMnSb2 system.展开更多
