Objective reality

According to quantum mechanics, a particle is in multiple states, called a “superposition,” until an observation (e.g., a measurement of its position or momentum) is made, at which point its wave function “collapses,” reducing the particle to a single state. A couple of years ago, physicists performed an experiment that showed that an observer could collapse the wave function of a photon, yet a subsequent experimenter could find the photon in a state of superposition. A writer for MIT Technology Review reported on this experiment and concluded that it means “there’s no such thing as objective reality.”

One could instead interpret the results as meaning that science is inherently unreliable, something we have known for some time already.
