Virology is at the crossroads of five frontiers : medicine, molecular biology, biochemistry, physics and human rights. In Western countries, the role of physics in virology is completely minimized while it plays the absolute greatest role. Interdisciplinarity is also of paramount importance in theoretical physics because of the quest for a unified theory between quantum fields and general relativity. Einstein’s theory is so powerful because it can very well formulate its own limits (one cannot go faster than the speed of light in all inertial frames). This incredible theoretical paradigm can also be developed in Virology. The first part and most important part of the present article is about a bio-technical trick for the ultra-precise detection of infectious airborne viruses. The second part of the present article is about the Theoretical Characteristics of the Omicron variant. The third part of the present article is about the Duality of the Omicron variant. And the fourth and least important part of the present article is about the Origin of the SARS-Cov-2 virus.
