SUMMARY

The discussion revolves around Leonard Susskind's explanation of quantum mechanics (QM) and the concept of time reversal in relation to particles like electrons and photons. Susskind posits that without measurement, reversing time would theoretically return particles to their original emitter. Participants debate the validity of this claim, questioning its provability and the nature of thought experiments in physics. The conversation highlights the distinction between theoretical predictions and empirical evidence in quantum mechanics.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with thought experiments in physics
  • Knowledge of time reversal concepts in physics
  • Basic grasp of particle behavior (e.g., electrons, photons)
NEXT STEPS
  • Research the implications of time reversal in quantum mechanics
  • Explore Susskind's theories on quantum mechanics and measurement
  • Study the role of thought experiments in theoretical physics
  • Investigate empirical evidence related to time reversal effects in quantum systems
USEFUL FOR

Students of physics, quantum mechanics enthusiasts, and educators seeking to explain complex concepts like time reversal and measurement in quantum systems.

Hi,

I had a look at Susskinds explanation about QM and this is pretty strange from my point of view.

Video:

Around minute 36.

He says that if there is no measurement after the electron/photon/whatever is going trough the slit and if you would reverse time the whatever would come back to the emitter. From a theoretical point this may be but isn't this just an unprovable statement?

Sure - but physicists do thought experiments like that all the time.

Make of them what you will.

Thanks

Hey Bill,

This is not a "Thought Experiment", this is something what you predict to be true or possible. Those thought experiments make sense like Einstein did because it is provable. To say that the inversion of time would lead to the same position in time is just a statement.

So, any proves for effects of time reversal things in quantum mechanics?
Give me data or let me know how I could explain a student QM with time reversion.

Thanks,
Jens
