zbigniew.modrzejewski Posted November 14, 2016 Posted November 14, 2016 In 1992, E. Podkletnov and R. Nieminen found that, under certain conditions, ceramic superconductor with composite structure has revealed weak shielding properties against gravitational force. In classical Newton's theory of gravity and even in Einstein's general theory of gravity, there are no grounds of gravitational shielding effects. But in quantum gauge theory of gravity, the gravitational shielding effects can be explained in a simple and natural way. In quantum gauge theory of gravity, gravitational gauge interactions of complex scalar field can be formulated based on gauge principle. After spontaneous symmetry breaking, if the vacuum of the complex scalar field is not stable and uniform, there will be a mass term of gravitational gauge field. When gravitational gauge field propagates in this unstable vacuum of the complex scalar field, it will decay exponentially, which is the nature of gravitational shielding effects. The mechanism of gravitational shielding effects is studied in this paper, and some main properties of gravitational shielding effects are discussed : arxiv.org/pdf/hep-th/0307225v1.pdf E. Podkletnov, R. Nieminen Physica C, Volume 203, Issues 3–4, 10 December 1992, Pages 441-444 Shielding properties of single-phase dense bulk superconducting ceramics of YBa2Cu3O7−x against the gravitational force were studied at temperatures below 77 K. A small non-conducting and non-magnetic sample weighing 5.48 g was placed over a levitating superconducting disk and the loss of weight was measured with high precision using an electrooptical balance system. The sample was found to lose from 0.05 to 0.3% of its weight, depending on the rotation speed of the superconducting disk. Partial loss of weight might be the result of a certain state of energy which exists inside the crystal structure of the superconductor at low temperatures. The unusual state of energy might have changed a regular interaction between electromagnetic, nuclear and gravitational forces inside a solid body and is responsible for the gravity shielding effect : www.sciencedirect.com/science/article/pii/092145349290055H Theoretical Analysis of a Reported Weak Gravitational Shielding Effect Max-Planck-Institut fur PhysikWerner-Heisenberg-InstitutMunchen, Germany Under special conditions (Meissner-effect levitation in a high frequency magnetic fieldand rapid rotation) a disk of high-Tc superconducting material has recently been found toproduce a weak shielding of the gravitational field. We show that this phenomenon hasno explanation in the standard gravity theories : http://arxiv.org/pdf...-th/9505094.pdf -1
Strange Posted November 14, 2016 Posted November 14, 2016 Because there is no scientific (reproducible) evidence or theoretical reason to think it is possible. Saying it is "impossible" is probably a bit too extreme, though. Who knows what future science will discover. But I am not holding my breath.
swansont Posted November 14, 2016 Posted November 14, 2016 ! Moderator Note You already have a thread on antigravity, satisfying a nonexistent demand. http://www.scienceforums.net/topic/100608-antigravity-split/ No need for another one.
zbigniew.modrzejewski Posted November 14, 2016 Author Posted November 14, 2016 Saying it is "impossible" is probably a bit too extreme, though. Who knows what future science will discover. So, why are you so certain that my hypothesis can not possibly be true ??
Strange Posted November 14, 2016 Posted November 14, 2016 I don't know what your hypothesis is. All you do is copy and paste things from random papers with no comment or explanation (but with garish colours added). I was therefore under the impression that you didn't have any hypothesis or opinion. And I don't believe I have ever said it (whatever it is) cannot possibly be true.
