From 3, 4, and 5, a final conclusion can be drawn:
6. This reference frame can only be relative to space itself, thus this objectively existing space is absolute space.
According to the original trajectory.
Little Niu had no doubts about the results of this experiment and thus proposed the concept of absolute spacetime, which became the biggest stain for later critics attacking him.
Everyone should know what happened afterward.
Einstein proposed the theory of relativity, suggesting that spacetime is one entity, and the two are inseparable.
In Einstein's spacetime view.
All things move in spacetime at the same speed, which is light speed.
Move faster in space, slower in time; the total speed always remains at light speed.
The structure of spacetime is a gravitational field, inseparable from each other and also inseparable from the material field,
Space tells matter how to move, matter tells space how to curve.
