Abstract
A most challenging question in physics and cosmology is: What is the origin of matter? Here, we introduce a new theory to answer this question; it is called the "quantum wave model" (https://link.springer.com/book/10.1007/978-3-031-48777-4). We know matters are composed of sub-atomic particles. We proposed that quantum particles are quantized excitation waves of the vacuum medium, which acts like a dielectric medium according to the Maxwell theory. One may challenge this wave model by asking: How can a wave have mass or charge? How can a wave have gravitational force? In this talk, we will show that these questions can be answered directly. Furthermore, the basic quantum wave equations (including the Dirac equation and the Schrödinger equation) can be derived directly based on the mechanism of vacuum excitation. This wave model also has strong implications for the future studies of cosmology. The key question now is: Can the hypothesis of this wave model be tested in experiment? We will show that this test can be done using experimental particle physics and atomic clocks
