Quantum Reality Is Either Weirdly Different Or It Collapses - Ars Technica

Amidst this year's craziness, folks are wondering if all of it is real in the vain hope of escaping this simulation gone crazy. Chris Lee wants you to consider Wigner's friend, which is a different take on Schrodinger's Cat, where quantum effects diminish before they become too large. But if they become too large, well... read on and blow your mind. After scooping your gray matter from the floor, Zeeya Merali expands upon This Twist on Schrödinger’s Cat Paradox With Major Implications For Quantum Theory and recent experiments playing with the concept of Wigner's friend. Also at macroscale dimensions, Ethan Siegel's surprised to learn how In Quantum Physics, Even Humans Act As Waves. Examining the celebrated double-slit test, and its descendants, there's a method to the proposed madness of treating H. sapiens as a particle and a wave which opens a whole can of weird worms. (CS)
