Discussion Overview

The discussion revolves around the relationship between Fatio–Le Sage's theory of gravitation and the concept of entropic gravity, exploring whether the two theories can be considered equivalent or related. Participants reference various academic papers and theories, examining the implications of entropic gravity in the context of modern physics and its potential connections to historical theories.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants propose that entropic gravity, derived from black hole entropy and quantum information, may have a connection to Fatio–Le Sage's theory of gravitation, which also involves particles moving throughout the universe.
  • Others argue that Le Sage’s theory contradicts current evidence, while entropic gravity aligns with observed phenomena, suggesting they make different predictions and are therefore not the same.
  • A later reply questions the credibility of journals publishing related papers, labeling some as predatory and suggesting that their findings may not be reliable.
  • Concerns are raised about the implications of equating Le Sage gravity with entropic gravity, with some asserting that such a claim would falsify entropic gravity.
  • Participants discuss specific papers that attempt to link Fatio–Le Sage's theory with modern theories, but the validity and relevance of these connections are contested.

Areas of Agreement / Disagreement

Participants generally disagree on the relationship between Fatio–Le Sage's theory and entropic gravity, with some asserting a connection while others firmly reject it based on evidence. The discussion remains unresolved, with multiple competing views present.

Contextual Notes

Participants express concerns about the credibility of certain journals and the implications of their findings, indicating a lack of consensus on the reliability of the sources referenced in the discussion.

A critique in Spanish of Verlinde's entropic gravity, (can be translated) https://francis.naukas.com/2017/12/23/inconsistencias-de-la-gravedad-entropica-de-verlinde/

The summary is that on the one hand we have a Newtonian theory type MOND (entropic gravity) and on the other hand we have a Newtonian graviton theory (Le Sage), and you want to know if they correspond. I understand that your doubt from a theoretical point of view may be interesting, but no one invests time in proving that wrong corresponds to wrong.

Needless to say, none of this corresponds to relativity.

Le Sage gravity is certainly a falsified theory
Excellent. I am glad you recognize that.

Jerome Wang said:
However, just as the falsification of other gravitational theories that are also based on space-time geometry does not mean that general relativity is falsified, the falsification of Le Sage gravity does not mean that any modifications and developments related to Le Sage gravity are falsified.
True, but insofar as they are not falsified, they must prove that they differ from Le Sage gravity. And we certainly don’t name successful theories after the creator of an earlier falsified theory.

This association only increases the skepticism towards entropic gravity. It does not justify Le Sage gravity.

Taking into account Milky Way could invalidate the hypothesis of exotic matter and favor a gravitomagnetic solution to explain dark matter and Supernovae evidence for foundational change to cosmological models, the part of this criticism based on the dark universe is not robust, while the robust part is whether it is consistent with itself and whether it can be consistent with general relativity.

However, even the criticism of the consistency of entropic gravity itself and whether it is compatible with general relativity is also seriously problematic, because Gravity from quantum information is based on ordinary quantum field theory in curved spacetime rather than Verlinde's method.

Stepping back, even without considering Gravity from quantum information, the failure of Verlinde's entropic gravity means it is necessary to re-examine the holographic principle and black hole thermodynamics.

At this point we're well off the thread topic, and this post is just personal opinion. That's not conducive to productive discussion. Thread closed.
