Discussion Overview

The discussion revolves around the nature of mass and its relationship to movement, exploring concepts from relativity, quantum mechanics, and theoretical physics. Participants examine the distinctions between rest mass and mass due to movement, questioning the existence and definition of mass in various contexts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • Some participants propose that movement contributes to mass, suggesting that mass increases with velocity according to relativity.
  • Others argue that rest mass is a fundamental concept, but its existence and definition are debated, with some questioning if it can exist without movement.
  • A participant introduces the idea that rest mass might be derived from rotational symmetry and conservation laws, linking it to quantum theory and the nature of particles.
  • There is a proposal that rest mass could be related to charge spinning on its own axis, raising questions about how to quantify this motion.
  • Some participants express uncertainty about whether mass can exist without motion, suggesting that any form of mass might inherently involve movement.
  • Mathematical formulations are presented, including equations related to energy, force, and acceleration, which participants use to explore the relationship between mass and motion.
  • One participant suggests that mass could be interpreted as electromagnetic change, proposing a connection to photon theory.
  • Another participant discusses the implications of mass in the context of particles encountering resistance, such as electrons in crystals, which complicates the understanding of mass.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views on the nature of mass, its relationship to movement, and whether rest mass can exist independently of motion. Participants express differing opinions and hypotheses without reaching a consensus.

Contextual Notes

Participants highlight limitations in defining mass, particularly regarding assumptions about motion and the nature of rest mass. The discussion includes unresolved mathematical steps and varying interpretations of fundamental concepts.

If the density is constant, then the divergence of velocity becomes frequency.

\nu =\vec{\nabla} \cdot \vec{v}

and the quantum of energy can also be given by

E = h \vec{\nabla} \cdot \vec{v}

Antonio Lao said:
mass is defined in physics as the product of density and volume. If the mass is constant as is commonly believed to be so, then the change of density and volume with respect to time must both be zero.

\frac{\partial \rho}{\partial t} = 0

\frac{\partial V}{\partial t} = 0

That cannot be right, Antonio. At best, those expressions reduce to 0 = 0.

Chronos said:
those expressions reduce to 0 = 0.

But using some ideas from the calculus of variation, the expressions indicate extremum conditions for finding a minimum or maximum.

The next step of the analysis is to surmise that mass does subject to change but its change is a prinicple of least action which is a Lagrangian function of the difference between potential energy and kinetic energy.

Mass is really subjected to a principle of double actions given by

A^2 = \int \int L*L dtdt
