Spirorus, the structure of spacetime ;)
After a long time looking deep into the structure of spacetime and after many times turning things inside-out and outside-in, tonight I came to the following conclusion. Spirorus (spiral torus or torus spiral) is the structure of space-time: Your particles move forward or my waves spread outward or we just turn around, there's no difference ! A spiral torus and a torus spiral are just 2 sides of the same structure which I call " spirorus " (pl. spirori) as illustrated by the pictures below: And as the spirorus turns around... we can see both things going upward (forward in space & time) and things spreading outward! So just depends on the choice of "self", one apears to move in different spacetimes (some ones call "multiple universes") while actually every one just moves around the same Universe. If your self is in a time line ( world line ) orthogonal to my self's time line (world line) then your advance in time will be my mot
