Current physics is divided in four incompatible domains because the scientific community has abandoned the intuitive principles of both absolute space and time (relativistic mechanics) as well as the deterministic character of the mathematical model (quantum mechanics). Quite often, we ask ourselves if we can agree to a picture of the cosmos which requires a framework of physics that contradicts our instinctive line of reasoning.This book presents bottom-up a new model of physics, which brings together the operational principles of three separate domains of physics. The new space-time model implies an abrupt departure from current generally accepted cosmic models. This results in a new picture of the cosmos. It can be described in a reference frame which is expanding exponentially without a Big Bang moment. When the ongoing physics is described in a steady state reference frame the continuously changing space-time coordinates result in fictitious forces. As a result, alternative explanations can be given for deep-space observations without dark matter and dark energy. When matter is included in the new model, both the Hamiltonian operator in quantum mechanics and gravity can also be treated as fictitious forces.
