Introduction to Thought Before I get into the underlying philosophy, I would like to clarify a few points. Without going into very deep details, I will say that according to one of the most established theories at the moment, in the early Universe after the Big Bang there were only protons, electrons, neutrons, photons, neutrinos and antineutrinos. Protons and neutrons combined with each other, forming the nuclei of the first atoms, and more specifically, hydrogen and helium.
