Physical interpretation of NUT solution
V.S. Manko, E. Ruiz
TL;DR
This paper provides a physical interpretation of the NUT solution in general relativity, describing it as the exterior field of two counter-rotating semi-infinite sources with negative masses attached to a finite rod.
Contribution
It offers a novel physical interpretation of the NUT solution involving negative masses and infinite angular momenta, clarifying its physical meaning.
Findings
NUT solution corresponds to two counter-rotating semi-infinite sources
Sources have negative masses and infinite angular momenta
Attached to a static finite rod of positive mass
Abstract
We show that the well-known NUT solution can be correctly interpreted as describing the exterior field of two counter-rotating semi-infinite sources possessing negative masses and infinite angular momenta which are attached to the poles of a static finite rod of positive mass.
