One question is that we always get the integrated photographs in good order when taking photograph though the phenomenon of particle-wave duality exist in the microcosm. Feynman path is probability and we should not get the good order photos. There is unknown mechanism in the microcosm. Another question is quantum gravitation how to connect the line and the dot. If I am the particle how I move. I think of doing some sewing and the unknown space was introduced. The two questions will be thought together and I give an able mechanism.
