Special Theory of Relativity & Conservation of Mass

Click For Summary

Discussion Overview

The discussion revolves around the relationship between the law of conservation of mass and the first postulate of the special theory of relativity, specifically whether conservation of mass is consistent across different inertial frames of reference. It explores theoretical implications and definitions of mass within the context of relativity.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if the law of conservation of mass fails to meet the first postulate of special relativity, suggesting a potential conflict.
  • Another participant indicates that the answer depends on how "mass" is defined, implying that definitions may influence the discussion.
  • A third participant requests further explanation to provide more helpful answers, indicating that clarity in reasoning is needed for a productive discussion.
  • A repeated question emphasizes the idea that if mass is conserved in one inertial frame, it should be conserved in all, suggesting a perspective that supports the compatibility of conservation of mass with relativity.
  • One participant asserts that conservation of mass does not conflict with the first postulate, asking for clarification on why there might be a perceived conflict.

Areas of Agreement / Disagreement

Participants express differing views on the compatibility of conservation of mass with the first postulate of special relativity. There is no consensus reached, and multiple competing perspectives remain in the discussion.

Contextual Notes

The discussion highlights the importance of definitions in understanding the relationship between mass and relativity, but does not resolve the implications of these definitions or the potential conflicts raised.

Does the law of conservation of mass fail to meet the first postulate of the special theory of relativity(the laws of physics are the same in all inertial frames of reference)?

Depends how you're defining "mass".
 
As with your last thread, if you explain your thinking a bit more we'll be able to give more helpful answers.

Conservation means does not change over time. What the first postulate would say is:

If mass is conserved in one inertial reference frame, then it is conserved in them all.

No. Why do you think it might conflict?
