Publisher's Synopsis
In modern physics, gravity is still an unknown physical phenomenon. Many attempts have been made to predict and observe the presence of gravitational waves based on quantum gravity theory, but nothing has been found yet. Of course, there are news that they have been discovered. The magnitude of this gravitational wave is so small that it compares the size of a hydrogen atom to that of the Sun. In reality, it means that the measured value is cannot simply be relied upon. In this book, we sought the origin of the mysterious force of gravity in the vacuum. Currently, the vacuum is theoretically possessed of matter or energy, and it is recognized that it is not completely empty due to the presence of dark matter and dark energy. We have newly interpreted the light propagation and gravity under the premise that the vacuum is made of a medium with the density much higher than that of matter we know and has near zero energy (zero point energy). Mass is nothing but the vibration energy of the solid vacuum, and the solid vacuum expands or distorted as much as the energy, yielding stress in the solid vacuum. Based on the physical discoveries and interpretations, it was discussed that the change in the stress of the solid vacuum will be the origin of gravity. Also, we reinterpreted cosmological phenomena based on the premise that the movement of matter is made in the form of wave by exchanging energy with the solid vacuum.
