In geometry, a sphere is the ideal shape. When enough mass clumps together to form an astronomical body, it tends to take the shape of a sphere. Any celestial body, regardless of its material composition, can achieve spherical form with a diameter of a few hundred kilometres. However, celestial bodies always deviate slightly from their spherical form, becoming elliptical to be accurate. As a result, practically all astronomical entities of sufficient size have an elliptical shape. The elliptical shape of an astronomical body and the elliptical orbits in which other astronomical bodies revolve around it are symmetrical. In this chapter, I’ll look at how astronomical bodies’ shapes and orbits are symmetrical. I’ll also talk about how a slight variation from the spherical shape causes physical time to travel forward. Finally, I’ll explain why particles and anti-particles form and recombine together.
