Magnetic Tension and the Geometry of the Universe
Open accessAbstract
The vector nature of magnetic fields and the geometrical interpretation of gravity introduced by general relativity guarantee a special coupling between magnetism and spacetime curvature. This magnetogeometrical interaction effectively transfers the tension properties of the field into the spacetime fabric, triggering a variety of effects with profound implications. Given the ubiquity of magnetic fields in the universe, these effects could prove critical. We discuss the nature of the magnetic-field--curvature coupling and illustrate some of its potential implications for cosmology.

When the standard Maxwell equation in a curved spacetime is expressed as a second-order differential equation of the potential vector, a curvature-coupled term also appears.
“In fact, when the standard Maxwell equation in a curved spacetime is expressed as a second-order differential equation of the potential vector (i.e., as a wave equation) a curvature-coupled term also appears [27], whose effects have been studied in [45, 46].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
