This book reviews QM, relativity and cosmogony, identifies assumptions that cause conflicts and need to be discarded and re-unifies physics. During the 20th century, physics has splintered into several conflicting paradigms. According to Classical Physics, the laws of nature are strictly deterministic, while according to Quantum Mechanics (QM) the laws are not deterministic. According to Classical Physics objects have a unique state, according to QM objects exist in a superposition of states. According to Classical Physics, the speed of light in vacuum is not the same for all observers, according to special relativity, the speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source. According to Classical and QM energy is conserved. According to Big Bang, all matter and energy emerged out of nothing, etc. Physicists tried to solve these conflicts piling questionable hypotheses on top of questionable hypothesis and failed. Target audience: Scientists and people interested in Classical Physics, QM, relativity, cosmogony and in resolving the conflict between these branches of science.
