Comment on "Frame-dragging: meaning, myths, and misconceptions" by L. F. O. Costa and J. Natário
arXiv:2110.09522
Abstract
I point out that the authors' interpretation of their calculations differs from the standard interpretation, described in Sect. 84 of Landau-Lifshitz book. This casts doubt on the authors' claim that Sagnac effect "arises also in apparatuses which are fixed relative to the distant stars (i.e., to asymptotically inertial frames); in this case one talks about frame-dragging".
2 pages, +1 page. Taking into account the authors Reply, I added further comments on the difference between their and Landau-Lifshitz interpretations
