A paper by Tajmar in CEAS Space Journal , probably the same experiment High-accuracy thrust measurements of the EMDrive and elimination of false-positive effects M. Tajmar, O. Neunzig & M. Weikert CEAS Space Journal (2021) link.springer.com/article/10.1007/s12567-021-00385-1

Experiments by the group of Martin Tajmar (TU Dresden) rule out anomalous laser-based propellantless thrusters as theorized by McCulloch and Taylor by many orders of magnitude. researchgate.net/publication/3…tors_for_space_propulsion Quote from Martin Tajmar and al: “Since modern propulsion systems are insufficient for large-scale space exploration, a breakthrough in propulsion physics is required. Amongst different concepts, the EMDrive is a proposed device claiming to be more efficient in conv…

The answer of Michael McCulloch to Tajmar's recent experiment. He criticizes the box where is the cavity is placed, claiming it cancels the thrust... physicsfromtheedge.blogspot.co…s-new-cavity-results.html I'm not convinced from what I naively understand of quantized inertia, but I'm not a physicist... The experiment is clearly good on measurement, but the question is what is measured ? The thrust of an Emdrive, or the thrust of a kitchen microwave?

The Traveller push an answer by Shawyer twitter.com/TheTrav49181490/status/1379916161253445632 forum.nasaspaceflight.com/inde…270.msg2217145#msg2217145 I attach the file converted as PDF Quote from R Shawyer: “(a) F ig7 from the 2021 paper now gives the dimensions of the dielectricdiscs and the loop orientation, which enabled the true operating modeto be determined. The SPR designspreadsheet, described in our IAC-20 paper, was used to calculate theresonant frequency at the interface axial length…

Breaking CoM is just a reason to be careful about experiments, not to reject any positive experiment by principle. But if good experiments on EmDrive don't work that is normal science... Only question is what have been tested... an EmDrive of a dead microwave oven. I'm open to success or failure possibility... I wait for the answer by Michael McCulloch...

A good experiment by Tajmar is making noise about EmDrive. No critics on the measurement. Only critics I heard is that the Q of the tested cavity was not what was claimed (Answer by Shawyer... hearsay) New Tests Cast Doubt On NASA’s Physics-Defying Thruster Design "Our measurements refute all EmDrive claims by at least 3 orders of magnitude." futurism.com/new-tests-cast-do…s-defying-thruster-design Scientists Just Killed the EmDrive After failing critical thrust tests, the "impossible" engine ha…

About MiHsC/Quantzed Inertie, it is often seen as an exact version of MOND... Here MOND seems supported by data Unique prediction of 'modified gravity' challenges dark matter theory phys.org/news/2020-12-unique-gravity-dark-theory.html Quote from Phys Org: “An international group of scientists, including Case Western Reserve University Astronomy Chair Stacy McGaugh, has published research contending that a rival idea to the popular dark matter hypothesis more accurately predicts a galactic pheno…

LAtests presentation by Roger Shawyer on Emdrive The paper emdrive.com/IAC20paper.pdf and the video vimeo.com/468607372 Quote from Roger Shawyer: “Designing an EmDrive thruster for a cubesat presents a number of challenges. Foremost is the need to reduce thesize of the microwave cavity, to enable integration into the cubesat structure. This requirement can be addressed byselection of frequency and operating mode. EmDrive propulsion systems have been designed to operate from 900MHz to around 8 GH…

newscientist.com/article/22186…late-the-laws-of-physics/ Quote from NewScientist: “NASA engineer's 'helical engine' may violate the laws of physics For every action, there is a reaction: that is the principle on which all space rockets operate, blasting propellant in one direction to travel in the other. But one NASA engineer believes he could take us to the stars without any propellant at all. Designed by David Burns at NASA’s Marshall Space Flight Center in Alabama, the “helical engine” exploi…
