Trouble for physical collapse models?

Click For Summary
SUMMARY

Recent experiments have definitively undermined physical-collapse theories in quantum mechanics, suggesting that these models are no longer viable. Philip Ball emphasizes that while these theories provided a natural explanation for quantum phenomena, their testability has led to their downfall. The ongoing precision of experimental results indicates that adjustments to parameters or complexity in models cannot salvage their validity. This marks a significant shift in understanding quantum behavior, akin to the challenges faced by supersymmetry.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with physical-collapse theories
  • Knowledge of experimental physics methodologies
  • Basic grasp of supersymmetry concepts
NEXT STEPS
  • Research the implications of quantum mechanics on physical-collapse theories
  • Explore alternative interpretations of quantum mechanics, such as Many-Worlds or Copenhagen interpretation
  • Study the latest experimental techniques in quantum physics
  • Investigate the status and challenges of supersymmetry in contemporary physics
USEFUL FOR

Physicists, quantum mechanics researchers, and students interested in the latest developments in quantum theory and experimental physics.

Experiments Spell Doom for Decades-Old Explanation of Quantum Weirdness
Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable.
Philip Ball

On Twitter, he writes "Personally I think recent experiments have indeed pretty much spelt doom for physical collapse models. They were always a long shot, and I applaud that they are testable - but the writing is on the wall."

It's like supersymmetry, you can always adjust some parameters to bigger/smaller values, or construct a more complicated model, so that the general idea is not ruled out by the last experiments.

Does this mean that when you measure a collapse model, the model itself collapses?

I read the same article and came looking!
