Any middle school student in the free world with a true interest in science, and proper resources to learn, has noticed from diagrams in books or on the web, or with iron filings on a piece of paper with a magnet beneath, that magnetic field lines have curvature.\u00a0 A local electric field between and surrounding two point charges also has curvature in the near space, except for on a line pointing directly away from the other charge.\u00a0 Dr. Schombert gives us a good diagram of this on the web.

The lines of a gravitational field, on the other hand, have no curvature in any instance, and \u201cthe gravitational force is entirely radial\u201d. ([2], pg 616)\u00a0 So, what is going on here?<\/p>\n
Earlier it was mentioned that the Coulomb force may transmit \u201cthrough the gravitational field in wave packets at group velocity, by phase shift and chirality\u201d [3].\u00a0 This could otherwise be stated as by phase shift and parity and, as physicists know, group velocity can be faster than the speed of light.<\/p>\n
To extend on this concept and compare then, if a rotational component is developed in a free graviton, it is due only to\u00a0Coulomb field production, and though free gravitons always travel in a straight line, neglecting lensing, when there are no charges present the rotational component of a free graviton would be zero.\u00a0<\/p>\n
