“…Both the penetration depth as well as the graviton wavelength is a complex number, as required by the positive cosmological constant measured in our universe (Novello and Neves, 2003). This explains, if the graviton mass would be significant, why we don't observe gravitational shielding in superconductors (Li, Noever andRobertson, 1997, Tajmar and although this was sometimes claimed (Podkletnov and Nieminen, 1992, Podekletnov, 1997, Reiss, 1999, Rounds, 1997.

Abstract. Superconductors have often been used to claim gravitational anomalies in the context of breakthrough propulsion. The experiments could not be reproduced by others up to now, and the theories were either shown to be wrong or are often based on difficult to prove assumptions. We will show that superconductors indeed could be used to produce non-classical gravitational fields, based on the established disagreement between theoretical prediction and measured Cooper-pair mass in Niobium. Tate et al failed to measure the Cooper-pair mass in Niobium as predicted by quantum theory. This has been discussed in the literature without any apparent solution. Based on the work from DeWitt to include gravitomagnetism in the canonical momentum of Cooper-pairs, the authors published a number of papers discussing a possibly involved gravitomagnetic field in rotating superconductors to solve Tate's measured anomaly. Although one possibility to match Tate's measurement, a number of reasons were developed by the authors over the last years to show that the gravitomagnetic field in a rotating quantum material must be different from its classical value and that Tate's result is actually the first experimental sign for it. This paper reviews the latest theoretical approaches to solve the Tate Cooper-pair anomaly based on gravitomagnetic fields in rotating superconductors.

“…The pertinent research is the work of Podkletnov [5,6], Solomon [7], Woods 1 , Cooke, Helme & Caldwell [8] and Hathaway, Cleveland & Bao [9]. Podkletnov [5,6] observed both gravity shielding or attenuation and amplification. Solomon [7] showed that any hypothesis on superconducting gravity shielding should eventually explain four observations, the stationary disc weight loss, spinning disc weight loss, weight loss increases along a radial distance and a weight increase.…”

“…Solomon [7] showed that any hypothesis on superconducting gravity shielding should eventually explain four observations, the stationary disc weight loss, spinning disc weight loss, weight loss increases along a radial distance and a weight increase. Woods, Cooke, Helme & Caldwell [8] attempted to reproduce Podkletnov's [5,6] work without much success as (quoting the authors) "the tests have not fulfilled the specified conditions for a gravity effect". Their primary focus was to reproduce Podkletnov's ceramic disc.…”

Two significant findings compel a rethink of physical theories. First, using a 7-billion-year-old gamma-ray burst, Nemiroff (2012) showed that quantum foam could not exists. And second, showed that gravitational acceleration is not associated with the gravitating mass, that gravitational acceleration g is determined solely by τ the change in time dilation over a specific height multiplied by c 2 or g = τc 2 . Seeking consistency with Special Theory of Relativity, as means to initiate this rethink, this paper examines 12 inconsistencies in physical theories that manifest from empirical data. The purpose of this examination is to identify how gravitational theories need to change or be explored, to eliminate these 12 inconsistencies. It is then proposed that spacetime is much more sophisticated than just a 4-dimensional continuum. And, that the Universe consists of at least two layers or "kenos" (Greek for vacuous), the 4-dimensional kenos, spacetime (x, y, z, t) and the 3-dimensional kenos, subspace (x, y, z) that are joined at the space coordinates (x, y, z). This explains why electromagnetic waves are transverse, and how probabilities are implemented in Nature. This paper concludes by proposing two new instruments and one test, to facilitate research into gravitational fields, the new torsion-, tension-and stress-free near field gravity probe, the gravity wave telescope, and a non-locality test.

“…This includes negative mass propulsion (Bondi 1957), theories that suggest that inertia and gravity are affected by vacuum fluctuations (Puthoff 1989 andHalsch 1994), and numerous other theories about the coupling between matter, electromagnetism, and spacetime (Dinowitz 1996, Froning 1997, Ringermacher 1994, Vargas 1991, Woodward, 1992, and Yilmaz 1992. Another recent development, which has yet to be credibly confirmed or discounted, is where anomalous weight changes are observed over spinning superconductors (Podkletnov 1992 Several experiments were suggested to test the theories linking inertia to vacuum fluctuations, including experiments described in existing literature (Forward 1996). And interest was expressed in continuing the experiments to test the claims of weight changes over spinning superconductors (Li 1997).…”
