"During the previous research on gravity, I summarized and optimized some of Galileo's ideas."
"Some were solved smoothly, but others encountered problems, to put it bluntly, very serious problems."
"Fat Fish, you should know, Galileo believed that there is no absolute reference frame in the world, only relative ones."
"Therefore, it is impossible to measure the velocity of this system through experiments within an inertial system."
"But in my view, time and space are two independent concepts, having no connection with each other, each possessing absoluteness."
"I believe space is absolute, by its nature, it remains independent and unaffected by external objects, always the same and immobile."
