The double slit experiment is indicating we are judging if something is part of this fallen reality or not. We became unique instead of as a whole. A physical person has pride, vanity, greed, lust, ego ..sin
The knowledge of judging evil allows humans to know something is physical. We didn't know/see what the difference was between a wave and particle before sin.
Scientists say decoherence is lost information to the environment. ..but the environment is this fallen reality. We are swimming in sin.
It goes deeper ..original sin caused disorder ..entropy. Unobserved waves are coherent and infinite. Decohered wave packets are finite. They caused disorder of the perfect order of coherence. SIN
This fallen condition causes Death, Decay, and Age.
Sin has something to do with physicality. Satan was allowed in the Garden because God needed something fallen to give us choice for Free Will. If God used a tree ..it means it was a physical tree ..and Satan is able to be around anything fallen apparently. The tree of knowledge would have looked normal to Adam because he couldn't judge between good and evil yet. The tree was physical in a garden that was not. God doesn't create evil so he used something from this fallen view.
Our eyes were open to Satan's perception because he was the first to cause disorder.
I think decoherence might be a present state ..the now. Physical objects can only be in the now ..not the future.
