Discussion Overview

The discussion centers around the concept of "conserving gravity," exploring whether gravity can be treated as a conserved quantity similar to mass or energy. Participants examine the implications of conservation laws in physics and the meaning of gravity in this context.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the possibility of conserving gravity, linking it to the conservation of mass and energy.
  • Another participant humorously claims to be conserving their gravity, suggesting a more colloquial interpretation.
  • A participant argues that "conservation of gravity" lacks clear meaning in physics, stating that gravity is not a specific quantity but rather an entire theory or interaction.
  • Another suggests that "gravity" could refer to the product of the gravitational constant and mass (G x m), which they believe may be a conserved quantity.
  • One participant posits that if a gravitational field exists, it would be conserved, indicating a belief in the conservation of gravitational fields.
  • A later reply notes that gravity is a conservative force, contrasting it with non-conservative forces like friction.

Areas of Agreement / Disagreement

Participants express differing views on the meaning and implications of "conserving gravity." There is no consensus on whether gravity can be treated as a conserved quantity, and multiple interpretations of the concept are present.

Contextual Notes

The discussion highlights the ambiguity in defining "gravity" and its conservation, with participants referencing different aspects of gravitational theory and conservation laws without resolving the underlying uncertainties.

Is it possible to conserve gravity ??

Is it possible to conserve gravity ??

If mass is from gravity and that mass is a form of energy which ..both the mass and the energy ..can be conserve ..then can the gravity also be conserve.??

How can you tell that a certain variable is conserved?

Yes. I'm conserving my gravity all the time.

"Conservation of gravity" is not something which has a clear meaning (or any meaning at all in fact) in known physics. There is, as you say, conservation of energy, or mass-energy if you want, conservation of charge, and still a lot of other conservation laws, but "conservation of gravity" doesn't seem to make much sense.
The reason for that is that "conservation" means something very precise in physics: it means that a quantity remains "the same" (or equivalent) for a given system if that system evolves over time. However, "gravity" is not a specific quantity. It is an entire theory, or an interaction if you want to. It is not a number, or another mathematical quantity such as a vector. So one wouldn't really know what it would mean, if "gravity were conserved", except in a kind of colloquial way like "the theory of gravity is conserved over the centuries" or something of the kind.
 


I think by "gravity" he means specifically G x m, which is as far as anyone can tell, a conserved quantity.
 


yes if there is gravity field it would be conserved, makes sense to me
 


Well, gravity is a conservative force. The only force I can think of that isn' conservative is friction.
