>>14201663It doesn't matter because even if particles returned to their "starting points" in "certain materials", the materials around the experiment (the rest of the universe) did not do so.
If I spin a top fast enough, and the top is cold enough, I could start making arguments that some particles return to their starting positions and velocities periodically. Now I just shrink that top to remove enough data so that I actually have something which looks statistically presentable.
The universe is just smoke and mirrors.
