GR is a mathematical model, and what I built is a physical model. The essence of GR is to describe the gravitational force under the influence of gravitational waves. Although gravitational waves are proposed by GR, but gravitational waves are real and actually affect gravity. Gravitational waves are a real natural phenomenon. I didn't want to overthrow GR, but as an ordinary scholar, they only need to master the physical model, and they don't need to study the mathematics behind it. Just like 1+1=2, for ordinary people, they need to know the result 2. They don't need to care why it is equal to 2. My theory is a physical model, just like Newton's universal gravitation.
