THE NUT. “Note that the concept fits within flat space-time. That an observer comparing one region with a reference frame based on the vacuum configuration might see non-trivial geometry is in agreement with diffeomorphism invariance.” (“relative geometry constitutes a first deviation from the properties of a standard space-time scenario.”) https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

CONCRETE examples of relative geometry. “These represent metrics that appear bent in the reference frame, but which represent flat space-time metrics.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

EXAMPLES. “In each case, the pair of relative geometry metric and reference frame metric represent metrics general relativity does not distinguish between, where a space-time originating in information exchange would do so, i.e. in agreement with different physics being observed (in terms of particle paths) for the two distinct scenarios (obstacles vs not).” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

FLATNESS. “The point made is that based on the symmetry of the particle diffraction, it is possible to identify a relative geometry metric that is compatible with general relativity, since it is flat.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

STANDARD VIEW. “An illustration of the slit diffraction example can be found in figure 1. There, the reference frame (x,y) is flat, and incident light rays would delineate straight lines in the absence of an aperture.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

DIFFERENT PERSPECTIVE. “With slits however, the maxima and minima of the light distribution after the aperture describe hyperbolae, which are bent with respect to (x, y) but straight lines in the relative geometry delineated in figure 1.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

NEUROLOGY. “When I was a medical student, it was said that neurology was the speciality with 1,001 diagnoses, but only one treatment. And that treatment was steroids.” (The Man Who Tasted Words by Guy Leschziner). In my early life I spent years working with neurologists and considered them the most clinically gifted of medical specialties. https://www.theguardian.com/science/2022/feb/06/guy-leschziner-reality-is-entirely-a-construct-of-our-nervous-system?CMP=Share_iOSApp_Other View in LinkedIn
