Main Question or Discussion Point
Pilot wave Quantum Mechanics is doomed from recent experiments but wait there's more:
In 2005, a student working in the fluid physicist Yves Couder’s laboratory in Paris discovered by chance that tiny oil droplets bounced when plopped onto the surface of a vibrating oil bath. Moreover, as the droplets bounced, they started to bunny-hop around the liquid’s surface. Couder soon figured out that the droplets were “surfing on their own wave,” as he put it — kicking up the wave as they bounced and then getting propelled around by the slanted contours of the wave.
Improbably, the person who put the irreparable crack in de Broglie’s idea is Niels Bohr’s grandson, the fluid physicist Tomas Bohr. A professor at the Technical University of Denmark who, as a child, enjoyed puzzling over riddles posed by his grandfather, Tomas Bohr heard about Couder’s bouncing-droplet experiments seven years ago and was immediately intrigued. “I felt a genuine interest in trying to see whether you could really get a deterministic quantum mechanics,” he said about his decision to enter the fray. Given his family history, he added, “maybe I also felt some obligation. I felt I should really try to see if it was true or not.”
