Discussion Overview

The discussion centers around the number density of neutrinos in a cubic inch, exploring theoretical estimates and sources of information. The scope includes theoretical aspects of particle physics.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant inquires about the number of neutrinos in a cubic inch.
  • Another participant estimates the number density of neutrinos to be around 2500 per cubic inch, based on a theoretical density of about 150 neutrinos per cubic centimeter.
  • A request for the source of the information is made by a participant.
  • The source cited for the neutrino density information is a publication by John J. Simpson related to the Sudbury Neutrino Observatory.

Areas of Agreement / Disagreement

Participants do not express disagreement, but the discussion does not reach a consensus on the exact number or its implications.

Contextual Notes

The discussion relies on theoretical estimates and specific sources, which may have limitations or assumptions not fully explored in the conversation.

How many are there in a cubic in inch?
 
Physics news on Phys.org
The number density of each neutrino species is theorized to be about 56 per cubic centimeter, for a total number density of around 150 neutrinos per cubic centimeter.

That's about 2500 per cubic inch.

where did you get that information, if you don't mind my asking
