We are aware of how skewed our perception of reality is. How we see the world is shaped by our senses, our societies, and our knowledge.
And you may want to rethink your belief that science will always provide you with an objective reality.Physicists may now verify a hypothesis that Nobel Prize winner Eugen Wigner initially put out in 1961. The setting of the experiment, dubbed “Wigner’s Friend,” is not too difficult. You begin with a quantum system that is in superposition, which implies that both of its states exist concurrently up to the point of measurement. In this illustration, the polarization (the axis on which a photon spins) is both horizontal and vertical. When they measure it, the system will collapse and the photon will be stuck into one of those two states. Wigner’s buddy is in the lab doing the experiment. However, the quantum system—which, crucially, also includes the lab—remains in superposition for Wigner, who is outside the lab and uninformed of the outcome of the experiment. Despite having different outcomes, they are both accurate. (If Schrödinger and his cat-in-a-box were both in a box, this would be analogous to Schrödinger’s cat, a thought experiment regarding superposition.) As a result, it seems as if Wigner’s reality and his friend’s reality coexist. And that’s a difficulty. It has been impossible to test this theory for a very long time. Wigner finds it difficult to calculate the quantum mechanics formula after seeing his buddy do an experiment. However, owing to recent advances, scientists were able to create a quantum mechanics experiment that would precisely replicate that.
