Photonic particles are always in motion maintaining their linear speed 'c' w.r.t. Their source position; birth of first ever universe, and the big bang

Mass moving or capable to move is energy. The very basic fundamental mass is, mass of light photon obtained from Plank's Black Body Radiation Formula E = h.f and the mass energy transformation relation E = mc2. These tiny photonic particles named Dark Photons whirling in space in racing with their anti particles always are in motion. When moving linear at speed c in space, they exhibit as light. They are the building blocks of the universe. They have gravity originally and in motion at speed greater than c in incremental value tending to zero; they exhibit electromagnetic property. When they smash against each other, they glue with each other exhibiting gluonic property. All matter in universe, quark to Black Hole is made up from these basic fundamental particles. The universe itself is born from them. These facts are detailed in this article.
