Aspect's experiment, bell's inequality, neutrino faster than 'c'.

Click For Summary

Discussion Overview

The discussion revolves around the implications of Bell's inequality in the context of the results from CERN regarding faster-than-light neutrinos. Participants explore the assumptions of Bell's inequality, the reliability of the CERN results, and the potential consequences for concepts like time and aether.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions the implications of Bell's inequality, suggesting that if the CERN results are correct, it may challenge the assumptions of reality and locality.
  • Another participant points out that the OPERA experiment at CERN had issues with a faulty cable, which may affect the reliability of the faster-than-light neutrino results.
  • There is uncertainty about the reliability of the CERN results, with one participant seeking clarification on the impact of the faulty cable.
  • A later reply mentions that researchers are working to determine the extent of the faulty cable's effect and expect to have answers soon.
  • Some participants express curiosity about whether the results imply backward time travel or if revisiting the concept of aether could resolve some implications.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reliability of the CERN results or their implications for Bell's inequality. Multiple competing views remain regarding the interpretation of the findings and their consequences.

Contextual Notes

There are limitations regarding the assumptions made about the CERN results and the implications of Bell's inequality, as well as the unresolved status of the faulty cable's impact on the experiment.

Hi just a quick question I was curious about.
Im not sure if the results from CERN about the faster than light neutrino have been verified, but given that this is true...
as I understand it bell's inequality assumes
1. the reality of the external world, independent of us "observers".
2. locality, ie, no faster than light signalling.
The results of Aspects experiment say that one of these has to go?
Assuming that the results from CERN were correct, what are the implications of this??
Does this mean things can go backwards in time??
If we were to go back to the idea of an aether does this solve some of the implications??
Im not in the field (although I am studying at an undergrad level) so a laypersons description as much as possible is appreciated!
 
Physics news on Phys.org
To bring things down to earth, the OPERA experiment (CERN) seems to have had a problem with a faulty cable.
 
Ohh so the results don't seem to be reliable?
 
Thanks for the update mathman!
