Principles of Modern Physics

<p><span style=color: rgba(0 0 0 1)>Modern physical theory is not a complete theory especially the overall self-consistency. The incompleteness of the theory is not limited to the quantum mechanics that describes the microstructure but also includes the macroscopic theory based on relativity. For example light theory space theory etc. In the theory of relativity the speed of light is constant is put forward as a basic assumption. In fact the constant speed of light is due to the Doppler redshift of light. The reason for the Doppler redshift of light is that the speed of light does not change. This article will take you to understand the physical principle of this mechanism.</span></p><p><br></p><p><span style=color: rgba(0 0 0 1)>Through cosmological redshift we can draw the conclusion that vacuum space is also a form of the existence of matter. This paper describes the physical characteristics of space material form from different physical angles. This book will also tell you why matter has mass how inertia is formed and why gravitational mass is equal to inertial mass. In addition all doubts in modern physics can be answered in the book including dark energy dark matter quantum entanglement etc.</span></p>
