Why if the particles used are sand rather than atoms do you end up with a uniform and identical result regardless of whether individually observed or not? Seems the accuracy and impact of the selected mediums and observing equipment influence the result. I don’t know anything about the equipment used or physics of atoms but for this to be valid it would need to be replicable for infinite different materials and equipment with different states of vacuum, no vacuum, gravity, electromagnetivity etc. and the observor(observing equipment) to be physically separated as well as all forces ( friction, gravity, electomagneticivity etc.) to be measured/monitored.
