A new lab rat to test general relativity

A central conundrum in physics is that general relativity
and quantum mechanics cannot both be right.
In general, quantum mechanics is only useful to describe properties on
very small scales, and as a result has very few consequences for the
macroscopic development of the universe.
General relativity is a theory of gravity, which is negligible at scales
for which quantum mechanics is applied.
However, physicists know that they can’t both be correct because general
relativity produces absurd results when considered at the same scale as quantum
mechanics. The only way to resolve this
issue is to gather data from experiments where both gravity and quantum
mechanics play a significant role.HangZhou Night Net

Researchers in Germany and France have identified* an experimental system* that meets these criteria. The experiment has its history in an anomaly observed in the field of superconductivity. When a superconducting ring is spun it will produce a magnetic field. The size of this magnetic field has been predicted by theory to an accuracy of 6 or 7 significant figures, thus when it was found that the magnetic field produced by niobium did not agree with that predicted, some new physics was in the offing. It was suggested that the difference was due to gravitational effects since general relativity predicts that a moving mass will produce a magnetic field, however this field is usually so small that it can generally be neglected. Nevertheless, a spinning superconductor, cooled below the critical temperature will produce a magnetic field due to both superconducting electron pairs and their mass.

Tajamar and Matos, set out to see if the gravitationally induced magnetic field could be accurately detected by measuring the acceleration fields surrounding a spinning superconducting ring. Their results have proven to be surprising; they have found that the acceleration fields are many times greater than those expected. Theoretically, these results can be explained by an increase of the mass of the photons that cause electrons to pair up and superconduct. This change in mass would bring a gravitational effect to the quantum world of superconductivity. If these results prove to be replicable and agree with the new theoretical predictions then physicists will have a new tool for testing general relativity at a scale where quantum mechanics can also be a significant factor. This might allow for the two to be brought into agreement with each other.
