Electromagnetic interactions are omnipresent in everyday life. These are part of the electroweak interactions, including the Higgs mechanism. However, the nature and microscopic structure thereof were a mystery. That mystery is solved in this book. We derive the observed charges and masses of the electroweak interaction from the equivalence principles, gravity and relativity, by analyzing the vacuum. We derive and clarify the origin of electroweak interactions: - Vacuum forming since the Big Bang constitutes space, time and cosmic phase transitions with a large scale energy spectrum. - That spectrum causes electroweak charges and masses. - Thereby, two-dimensional charge space forms. - Hereby, the electric charge, the weak angle, a non-electric charge, a hypercharge, an isospin charge and isospin form. - Electroweak masses originate from transitions at the large scale spectrum. Using the local principles of the formation of vacuum, we derive general relativity and results beyond: the density of vacuum, quantum physics, cosmic phase transitions as well as the electroweak interactions, charges and masses. Our results are in precise accordance with observation, whereby we do not execute any fit. Invited to discover the nature of electromagnetic and weak interactions are classes from grade 10 or higher, courses, research clubs, enthusiasts, observers, experimentalists, mathematicians, natural scientists, researchers …weiterlesen
