@inproceedings{Deriglazov2021CommentOM, title={Comment on"Frame-dragging: meaning, myths, and misconceptions"by L. F. O. Costa and J. Nat\'ario}, author={Alexei A. Deriglazov}, year={2021} }

A worldline x = (ct,x), where t ∈ R while x = const, is called an observer at rest (or laboratory observer) [1], see the discussion around Eq. (2) in [1]. In Sect. 2.1, after mentioning the Sagnac effect in flat spacetime (see Sect. 89 in [2]), the authors state: ”In a gravitational field, however, it (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.”. To confirm the…

Comment on “Acceleration of particles to high energy via gravitational repulsion in the Schwarzschild field” by C. H. McGruder III

Abstract By direct computations, we show that “repulsion” in the Schwarzschild field can not accelerate an outgoing particle, and thus represents pure coordinate effect. In other words, the repulsion…

Abstract Gravitational repulsion is defined to mean that a free particle instantaneously at rest is accelerated outwards from the mass center. It is shown that there is no gravitational repulsion in…

Abstract Gravitational repulsion is an inherent aspect of the Schwarzschild solution of the Einstein-Hilbert field equations of general relativity. We show that this circumstance means that it is…
