What Happens to High-Energy Particles in Cosmic Rain?

Click For Summary

Discussion Overview

The discussion revolves around the behavior of high-energy particles, referred to as "cosmic rain," when they interact with detectors. Participants explore the nature of these particles, their wave-particle duality, and the implications for energy conservation during detection.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that high-energy particles must behave as waves, referencing the double-slit experiment and questioning what happens to their energy when they encounter a detector.
  • Another participant counters that particles do not "go through both" slits and notes that some energy is deposited as they pass through matter or are stopped by detectors like NaI.
  • A third participant argues that high-energy cosmic rays cannot produce observable interference effects due to their extremely small de-Broglie wavelength, implying they behave more like classical particles in practical scenarios.
  • This participant also emphasizes that energy conservation holds true in the double-slit experiment, stating that the energy of the incoming particle is equal to the energy detected, regardless of the interference pattern.
  • A later reply expresses appreciation for the insights gained from the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the wave-particle nature of high-energy cosmic rays and the implications for energy conservation, indicating that multiple competing perspectives remain without a clear consensus.

Contextual Notes

The discussion includes assumptions about the applicability of quantum mechanics to high-energy particles and the conditions under which energy conservation is considered. There are unresolved questions regarding the specifics of energy deposition and detection mechanisms.

I was just reading the article about “cosmic rain” here and they talk about these very high energy particles striking a detector. But as I understand things, these have to be waves, not particles, put up a double slit and these things will go through both as waves (and since they do not know they will encounter a slit they must be waves.) So what happens to all their energy? They hit a detector as a wave, canceling themselves or, and this is my question, just what is happening here to these high energy things?

Read some more. things don't 'go through both'.

some of it is deposited along the way when they go through matter. Or they are being stopped, like photons in NaI.
 
You can't make a double-slit experiment with high-energetic cosmic rays. As all particles, they follow quantum mechanics, but their de-Broglie wavelength is so incredibly tiny that you cannot observe interference effects with them.
For all practical purposes you can ignore quantum mechanics and they look like classic particles.

Independent of cosmic rays: Energy is conserved in the double-slit experiment (it is conserved everywhere). Send a particle with energy X in and you'll get energy X out. Where exactly you detect the particle depends on the interference pattern.
 
I am not sure if it is appropriate to post a thank you. I did learn from your answers.
