What Is The Observer Effect. .
"Quantum mechanics is the study of how particles at the atomic and subatomic level interact with each other and their environment. The observer effect is the phenomenon in which the act of observation alters the behavior of the particles being observed. This effect is due to the wave-like nature of matter, which means that particles can exist in multiple states simultaneously. When an observer measures a particular property of a particle, they are effectively collapsing the wave-function of that particle, causing it to assume a definite state".
