SUMMARY

The discussion focuses on the perception of systems during decoherence, highlighting that decoherence times for macroscopic objects are significantly shorter than human perception times. Specifically, the decoherence times for observable phenomena are below nanoseconds, while human perception operates on a timescale of approximately 0.1 seconds. The inability to perceive decoherence is attributed to the fact that the brain processes information at least one million times slower than the decoherence events occurring in the environment. This discrepancy explains why we do not observe systems during the decoherence process.

PREREQUISITES
  • Understanding of quantum decoherence principles
  • Familiarity with human perception and cognitive processing times
  • Basic knowledge of physics, particularly regarding light and distance
  • Awareness of the Planck time and its significance in quantum mechanics
NEXT STEPS
  • Research quantum decoherence and its implications in quantum mechanics
  • Explore the relationship between perception and cognitive processing speeds
  • Study the effects of distance on light travel time and its impact on perception
  • Investigate the significance of Planck time in quantum theory
USEFUL FOR

Physicists, cognitive scientists, and anyone interested in the intersection of quantum mechanics and human perception will benefit from this discussion.

Yeah, the beta movement from pshycology for example, it impose that a perceptions matter in a 0,1 s (+ or -), but this need a physical explanation. The decoherence times for examle cat alive cat dead is very low than this. But we are there while decoherence. Why we don´t perceive it. The decoherence time for position in macroscopic objects is very long for perception times like physcology. But it is long for Planck time. Why is the reason we don´t perceive the system while decoherence??

Decoherence times for everything you can see are below the timescale of nanoseconds. If the object is more than 30cm away from you, not even the light from the object can reach you in that time. Your brain is at least 1 million times slower.

Anyway, the timescale is not so important here: Your eye (or any other organ) cannot distinguish between ("measure") different results without having a complete decoherence between those different results.
