Discussion Overview

The discussion centers around a proposed alternative to General Relativity (GR) based on k-calculus. Participants express varying opinions on the validity and seriousness of the claims made in the associated paper, exploring its implications in the context of both special and general relativity.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants express skepticism about the proposed alternative to GR, describing it as "nonsense" and suggesting it lacks credibility.
  • Others acknowledge that k-calculus is a well-established framework for understanding special relativity but question its application to general relativity.
  • One participant notes that the author of the alternative has had multiple papers rejected by journals, which raises concerns about the validity of the claims.
  • There is a distinction made between the usefulness of k-calculus for teaching special relativity and its limitations when applied to general relativity.
  • Some participants emphasize that personal opinions are being shared and do not reflect the views of the forum's management.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the proposed alternative to GR, with some dismissing it outright while others acknowledge k-calculus's established role in special relativity but question its relevance to general relativity.

Contextual Notes

There are unresolved questions regarding the applicability of k-calculus to general relativity and the specific claims made in the referenced paper. The discussion reflects a variety of opinions without reaching a consensus.

Hello, I stumbled upon this work some time ago. It is based on the k-calculus and claims to be a viable alternative to GR. It seems to me to be a whole load of arm waving and even exagerated claims. I am no expert on this though and so would like some more knowledgeable opinions on whether the paper should be taken seriously.

K-calculus is fine and well established as a way to understand special relativity.

As far as geometric optics goes, I'm not terribly familiar with it, but the paper itself gives us a Big Clue.

In recent times the author has written several papers on the subject of his proposed
alternative to general relativity, [1, 2, 3, 4, 5] all of them rejected by the journals
to which they were submitted;
 
It's nonsense IMO. K-calculus has big problems in GR. That is, btw, a personal opinion and does not represent the views of PG management.
 
The first on the reference list (other than to his own work) is:

[6] Tom Van Flandern. The speed of gravity – what the experiments say.
Phys. Lett. A, 250:1–11, 1998.

Not really helpful if one proposes an alternative to GR...

K-calculus == special relativity, not general relativity, at least in its standard form. Let's not through out the baby with the bathwater - K-calculus is a perfectly fine way to understand SR. One of the benefits of the K-calculus approach is it's simplicity - it doesnt' require more than high school math, so it's a good way to teach SR to high school students.
