Time-scale of Compton scattering

Click For Summary

Discussion Overview

The discussion revolves around the time-scale of Compton scattering, exploring whether it can be considered an instantaneous event or if it has a measurable duration. Participants engage with concepts from classical physics and quantum mechanics.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether Compton scattering has a δt or if it is instantaneous, drawing an analogy to classical elastic collisions.
  • Another participant suggests that relating the transferred energy to a time using the relation ##\delta t \approx \frac{\hbar}{\delta E}## could yield interesting insights.
  • A different viewpoint posits that even instantaneous events might be assigned an infinitesimal duration in relation to Planck time.
  • Some participants express uncertainty about the nature of physics at the Planck scale, indicating a lack of consensus on how it relates to the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the nature of time in relation to Compton scattering, with no clear consensus on whether it is instantaneous or has a definable duration.

Contextual Notes

There are limitations regarding the assumptions made about the nature of time and the applicability of quantum mechanics at the Planck scale, which remain unresolved.

Hey all,
Anyone know if there is a δt to Compton scattering or is it an instantaneous event, entertaining classical physics...billiard balls colliding in an elastic collision.

Cheers

That depends on your interpretation. Relating the transferred energy to a time via ##\delta t \approx \frac{\hbar}{\delta E}## might give some interesting results.
 
Interesting. Not to go out there too much but that does beg the notion that every event (even instantaneous ones) can be given some infinitesimal duration relative to Planck time.

We don't know how physics at the Planck scale looks like.

Not challenging that notion.
