Ask Ethan: Can hidden variables save quantum physics? | by Ethan Siegel | Starts With A Bang! | Jan, 2023

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What’s less well appreciated is that matter particles also exhibit those wave-like properties. Even something as massive as a human being should have wave properties as well, although measuring them will be difficult. (Credit: Fabrizio Carbone/EPFL)

Ever since the discovery of the bizarre behavior of quantum systems, we’ve been forced to reckon with a seemingly uncomfortable truth. For whatever reason, it…
