Content: In “Hidden In Plain Sight” physicist Andrew Thomas says: An excellent definition can be found in the book Quantum Enigma by Bruce Rosenblum and Fred Kuttner: “ Whenever any property of a microscopic object affects a macroscopic object, that property is ‘observed’ and becomes a physical reality.” For example, when a microscopic photon hits the macroscopic screen in the double-slit experiment, then that will reduce the quantum superposition state of the photon to a single value (the single mark it leaves on the screen). This explains why we do not see bizarre quantum superpositions — such as a cat being both alive and dead at the same time — in the human-scale, macroscopic world. So as long as there is a macroscopic effect from a quantum entity, that object can be considered to be “observed” or “measured” — with no need for a conscious human observer. In the double-slit experiment, the electron is “observed” by the detector at the slit. The state of Schrodinger’s Cat is “observed” by the air it breathes (or not) inside the box, which is “observed” by interacting with the molecules of the box, which is “observed” by interacting with photons in the rest of the universe. The simple act of a particle *interacting* in any way with other particles in the universe, means it is “observed” by the universe. It’s quantum state (or wave function) collapses at that point;
