Sound waves carrying mass and how to measure it

Click For Summary

Discussion Overview

The discussion revolves around the concept of sound waves potentially carrying mass, referencing a study that supports this idea. Participants explore how this mass might be measured and the implications of sound energy in relation to kinetic energy and gravitation.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions how the mass of sound waves is measured and whether results would differ in total darkness.
  • Another participant suggests that the concept of invariant mass may implicitly support the idea that sound waves can carry mass.
  • A third participant raises a question about the role of photons in energy transfer, noting that if photons do not carry mass, it complicates the understanding of energy transfer processes.
  • One participant asserts that energy, including kinetic energy, gravitates, and that sound energy is a form of kinetic energy, referencing a Wikipedia article for further explanation.

Areas of Agreement / Disagreement

Participants express differing views on the implications of sound waves carrying mass and the role of photons in energy transfer. The discussion remains unresolved with multiple competing perspectives presented.

Contextual Notes

There are limitations in the discussion regarding the definitions of mass and energy, as well as the assumptions underlying the relationship between sound energy and gravitation. Some mathematical steps related to these concepts remain unexplored.

Isn't that implicit in the concept of invariant mass?

ESL. If photons only carrying particles without mass, then how does the energy-transferring-process work at this point?

Nobody mentioned photons.

Energy gravitates. Kinetic energy gravitates. Sound energy is a form of kinetic energy.

The Wikipedia article explains it better than I can.
