In our previous book, "Origin of Gravity and New Cosmos (ISBN 9781713042020, 12.2019)", in the regime of the new vacuum paradigm that the vacuum is made of a very dense matter and devoid of energy, we addressed the origin of gravity and reinterpreted cosmological phenomena. When energy is added to the solid vacuum, it is deformed and distorted as much as the amount of energy. As a result, stresses develop not only in the solid vacuum and but in ordinary matter, and the variation of the stress is the origin of all physical phenomena in the new vacuum paradigm. The solid vacuum does not convert to any other things, but the energy stored in it varies upon changing the center of vibration in the vacuum lattice, and the transfer of matter or energy is nothing but the transfer of stored energy in the solid vacuum. This book attempted to interpret the electromagnetic behaviors of materials in terms of their interaction with the solid vacuum. We proposed a new atomic model, and based on this model, we newly analyzed the characteristics of chemical bonding, including hydrogen bonding, to grasp electrical and magnetic phenomena based on the analysis, and to present a new paradigm for electrical conductivity and superconductivity. Both superconductivity and electrical conductivity in solids are the same flow of electricity. It is a "flow" of electrical energy. If an electric current is a flow of energy, charged particles called electrons does not need to deliver the energy directly. No one has ever seen these charged particles flowing through conductors. There seems to be no way to observe them. There are no particles that carry the elastic energy of solids. The relative positions of the constituent atoms or molecules propagate in the form of waves. Electricity also does not involve particles that carry its energy. In this regard, we accessed electricity and searched for the nature of superconductivity. To do this, a new atomic model was set up and electromagnetism was newly defined. We wanted to create a new paradigm to explain electromagnetic phenomena in solids. We did thought experiments for new solid-state physics and recorded the experimental results in this book. It won't be easily understood for the readers out there. It appears to an absurd but is a fun challenge for new physics.
