If it constitutes one of the most successful physical theories and it explains a lot of things, the standard model is nevertheless far from perfect. Some theoretical physicists have now been working for a few years on a new physical model going beyond the standard, which could modify it so that it agrees with existing data. There are physical phenomena in nature that the Standard Model cannot explain such as gravity, dark matter, the mass of neutrinos ... Quantum physics today allows us to analyze the reality of the world around us. But what is reality to a part of energy and information? This book attempts to enlighten those who seek to understand reality.
