A new theory of time-space
The main idea of a new theory of time-space is that time is a expression of change in motion distance and curvature. In a word, time is equivalent to space, and vice versa. Time is space. Space is time. Two things are same.
It is unnecessary to postulate that time is the forth dimension. For example, time-space of the earth system, sun system and atom, and so on, is spherical. The rectilinear motion in plane coordinates or three dimensions in classical physics occurs in spherical time-space and must be influenced by it. This is reason why time-space is a four dimensions.
According this new theory of time-space, there are three kinds of clock. Those are current clock, thing clock and Doppler clock. Every clock has its own second unit.
Time-space is moving.
Active and passive motion of time-space forms a whole world of physics. The new theory gives us a definite answer to what the nature of wave, light, gravity, energy, passive inertia, active inertia, electricity, magnetism, special and general Doppler principle is.
