I'm in a deep discussion with a friend. He says that the Standard Model of particle physics is actually known by Standard Model of cosmology and that both are the same and that the SM of particle physics is in the Minkousky geometry.... I disagree about this, I do think that the SM of particle physics is one thing and the SM of cosmology is another, and even if the SM of cosmology includes the SM of particle physics and applies it to concepts like geometry, they are different. Who is wrong? Or better, whats is the truth?
