Discussion Overview
The discussion centers on the implications and observations related to a potentially changing Planck's constant, including the conditions under which such changes could be detected and the hypothetical existence of other universes with different values of Planck's constant. The scope includes theoretical considerations and speculative scenarios.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants question how slowly Planck's constant would need to change for it to be observable, and what size of discrete changes would be necessary for detection.
- Others argue that these questions cannot be answered without a theoretical model, noting that no such model has been constructed for a changing Planck's constant.
- One participant suggests that Planck's constant is merely a unit definition and questions the meaning of a "changing" Planck's constant.
- Another participant proposes using the Schrödinger equation to explore altered solutions based on variations in Planck's constant, raising the possibility of a universe with a different value of h(bar).
- However, some participants challenge this idea, stating that the Schrödinger equation does not allow for a changing Planck's constant and that it can be expressed in units where it does not appear.
- There is a mention of the historical context regarding the fixing of the speed of light and the plans to render the uncertainty of Planck's constant negligible, which some participants view as off-topic.
- One participant expresses a disagreement with the notion that speculation is unwelcome in the forum, asserting that mathematical understanding can provide answers.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the nature of Planck's constant or the implications of its potential variability. Multiple competing views remain regarding the feasibility of discussing hypothetical scenarios and the applicability of existing models.
Contextual Notes
Limitations include the absence of a theoretical framework for a changing Planck's constant and the dependence on definitions of units. The discussion also reflects differing opinions on the appropriateness of speculative questions in the forum.
