Discussion Overview

The discussion revolves around the propagation speeds of various interactions in physics, specifically questioning whether all types of interactions propagate at the same speed, denoted as c, which is the speed of light. The scope includes theoretical considerations and quantum characteristics of interactions.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that the velocity of all types of interactions is the same as the speed of light, c, based on a specific equation involving phase and momentum.
  • Another participant proposes that even if the transfer boson is massive, the velocity of propagation of interaction remains c due to quantum characteristics.
  • A different viewpoint indicates that the concept of speed of interaction is classical and may not apply in quantum contexts, where interactions could behave differently.
  • There is a challenge to the idea that massive transfer bosons imply slower interaction speeds, with one participant affirming that classical interpretations suggest weak interactions have small velocities due to massive bosons.

Areas of Agreement / Disagreement

Participants express differing views on whether all interactions propagate at speed c, with some supporting the idea and others contesting it based on quantum mechanics and classical interpretations. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

The discussion includes assumptions about the applicability of classical concepts to quantum interactions and the implications of massive transfer bosons on interaction speeds, which are not fully explored or resolved.

Please teach me whether this is correct:
It seem to me that the velocity of propagating of all type of interaction is the same value c as the velocity of light.Because equation of propagating of phase p.x=0 leads to v=E/p^(where p^-modul of spacelike-momentum)=square(c)/v then v=c.Where p is 4-momentum of a quantum and p.x is phase of field operator.
Thank you very much in advance

It seems that even in case the transfer boson is massive,the velocity of propagation of interaction still is c,because of quantum characteristic.Is that correct?
 
<Speed of interaction> is a classical concept applicable to classical theories. (Gravitational and e-m waves traveling at c). However, the 4 interactions can be seen from a quantum perspective, where <speed of interaction> notion will no longer apply.

No. :rolleyes:
 
Then classical saying the week interaction has the small interaction velocity,because of massive transfer boson?
