Discussion Overview

The discussion explores the feasibility of using neutrinos for communication, specifically the concept of a "neutrino telephone." Participants consider the implications of neutrinos' ability to pass through matter without obstruction, as well as the challenges associated with generating and detecting neutrino signals.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants propose that a neutrino telephone could overcome obstructions faced by traditional cell phones due to neutrinos' ability to pass through buildings and the Earth.
  • Others argue that the difficulty in detecting neutrinos, as evidenced by the large and complex Auger Observatory, raises questions about the practicality of creating a reliable communication signal.
  • A participant raises concerns about the safety of generating strong neutrino signals, particularly regarding the potential for gamma radiation exposure.
  • One participant humorously suggests using a handheld nuclear reactor to create binary signals, while also questioning the possibility of sending messages back in time using neutrinos.

Areas of Agreement / Disagreement

Participants express differing views on the practicality and safety of using neutrinos for communication, with no consensus reached on the feasibility of the concept.

Contextual Notes

The discussion highlights limitations related to the detection of neutrinos, the generation of signals, and the potential health risks involved, but these aspects remain unresolved.

Could we somehow develope a neutrino telephone? Since they pass through everything, you wouldn't have to deal with obstructions like buildings which are often an issue with cell phones.

If they can pass through building and even the Earth that easily, what makes you think it will interact more easily with a "telephone" to produce a signal? Just look at how big and tedious the Auger Observatory is currently in trying to detect neutrinos.

Zz.
 
And on the other end, how would the sender create a strong neutrino signal without incidentally irradiating himself with gamma rays?
 
get lead pants and turn your hand held nuclear reactor off and on quickly and you have binary, then bury your phone underground to try to receive the signal...

if we can use neutrinos to send signals we can send messages back in time can't we?
