All space object cluster into a sphere why? Equation for photon losing ENERGY as it travels a unit distance? Gravity surrounding an massive object has field connecting mass n space more the mass more the field density. Photon moving through this field losses energy.like electron moving perpendicular to magnetic field jumping from 1 field to another losses energy hence the collapse of wave function.

Gravity. All the particles are being pulled to the center of gravity, so that naturally forms a sphere. Photons do not lose energy per unit distance. No
