You make a request by setting something that can analyze the particle during its life/path. You are saying you want the particle to be real/physical.
Double slit interpretation:
Randomly shot particles are shot through a double slit, if no one places a detector in the path of the particle, the unobserved particle will be in the form of two waves (one for each slit) . Depending on the which wave ends up with more energy (after the split) ..the final position of a channel representing a fringe will be the final resting place of the now collapsed particle. If the energy wasn't unbalanced, I would expect to see only a single channel of fringe be filled in.
Now a detector gets placed anywhere along the path between the cannon and the final landing screen. The particle shot will immediately collapse upon leaving the cannon because the type of life that particle has, has already been decided. It won't be waves, just a particle. It's been pulled from the unobserved quantum realm and made physical in spacetime. It will go through one slit and hit the final screen in a normal clump.
If you accept this interpretation ..then you accept a particle being either a particle or waves ..not both at the same time.
You now also know that placing a detector in an experiment is a request from a human to the dimension of unobserved qm to swap quantum waves into something physical.
Observation is then a property of spacetime.
General Relativity = Spacetime = the theory of the large scale
Unobserved QM = Waves = the theory of the small scale
They are both dimensions in the same domain
Observation is then a request to bring an object from one dimension to the other. Boom, unified.
