Discussion Overview

The discussion revolves around the solar neutrino problem (SNP), which concerns the discrepancy between the predicted and measured number of neutrinos emitted from the sun. Participants explore the historical context, experimental findings, and potential explanations for the observed phenomena.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants describe the solar neutrino problem as the observation that fewer neutrinos were detected from the sun than predicted by solar models.
  • One participant mentions Ray Davis's original experiment using cleaning fluid as a detector, which has been confirmed by subsequent experiments with more advanced detectors.
  • Another participant suggests that the discrepancy may be due to electron neutrinos transforming into other types of neutrinos that are not detected.
  • There are requests for additional resources beyond common search engine results to learn more about the topic.
  • One participant provides a Wikipedia link as a starting point for further reading, while another criticizes the reliance on Wikipedia and suggests visiting John Bahcall's webpage for more authoritative information.
  • A later reply humorously reframes the issue, stating that it is not a problem but rather an opportunity.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the solar neutrino problem, with some framing it as a significant issue and others suggesting it presents an opportunity. There is no consensus on the implications of the findings or the best resources for further information.

Contextual Notes

Participants reference historical experiments and ongoing debates regarding the interpretation of neutrino behavior, but the discussion does not resolve the underlying uncertainties or assumptions related to the solar neutrino problem.

hello everyone,

what is the solar neutrino problem ?
 
Physics news on Phys.org
The SNP was the fact that fewer neutrinos were measured coming from the sun than were predicted to be produced in the sun using models of the sun's interior. The original expt was done by Ray Davis using cleaning fluid as a detector. It has now been confirmed by several more elaborate (and expensive) detectors. Davis received the Nobel prize for his measurement.
The current explanation of the lack of neutrinos reaching the Earth is that some of the electron neutrinos produced in the sun change into other types of neutrinos that don't get measured.
 
ah ok ...quick response btw.
do u know of any websites i can look this up on , apart from the few that pop up on the 1st page of google searchs if any .
 
Argh! Another Wikipedia reference!

Go the the "horse's mouth". Read the links in the late John Bahcall's webpage.

Zz.
 
It's not a problem - it's an opportunity!
