I have written and published a paper “Study of Quantization of Space-Time Explains Matter and Its Aspects” and showed that space-time is made of virtual pairs of points one forward in time and the other backward in time and share their time which is the elementary unit of time, which I calculated to be t0 = e2μ0 which is 3/5 the Planck time and shows this time determines the elementary unit of charge. This space-time does effect the motion of matter and its effect is the i in quantum mechanics
Keywords : Why are our equations imaginary? Quantization of space-time, elementary unit of time and space
