BOUNDARY EFFECTS. “At the edges, the shortest path for information flow would be around the edges, and that information exchange would reshape the space-time compared to its shape in the vacuum configuration.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

HILBERT’S DREAM. “Hilbert’s idea is the culmination of two thousand years of mathematical tradition going back to Euclid’s axiomatic treatment of geometry, going back to Leibniz’s dream of a symbolic logic and Russell and Whitehead’s monumental Principia Mathematica. Hilbert’s dream was to once and for all clarify the methods of mathematical reasoning. Hilbert wanted to formulate a formal axiomatic system which would encompass all of mathematics.” https://lnkd.in/eRAK9d4N View in LinkedIn

THE COMPARATOR. “The difference is observable in relation to a set reference frame where light rays describe straight lines in the absence of the objects in question.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

ELECTRICAL STRUCTURES. “The functional properties of materials and devices are critically determined by the electromagnetic field structures formed inside them, especially at nanointerface and surface regions, because such structures are strongly associated with the dynamics of electrons, holes and ions.” https://lnkd.in/eRAK9d4N View in LinkedIn

BOUNDARY EFFECTS. “If the discussion above appeared too unspecific, simply replace ‘obstacles to information flow compatible with approximately flat space-time’ with a tabletop experiment looking at the effects edges/apertures have on light rays, compared with how light propagates when those objects are removed.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

IMAGES of cosmic magnetic fields. “Most of the visible matter in the Universe is ionized, so that cosmic magnetic fields are quite easy to generate and, due to the lack of magnetic monopoles, hard to destroy. Magnetic fields need illumination by cosmic rays, gas or dust to be detectable. Large regions in the Universe may be permeated by “dark” magnetic fields.” https://lnkd.in/eRjhYGXz View in LinkedIn

DIFFRACTION GRATING. “Interestingly, our example of an insulating surface above has a direct parallel in e.g. a disc giving rise to particle diffraction, an example of the wave-particle duality. This type of effect is present for any configuration of apertures or edges.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

CORE MAGNETISM. “The fact that jets in AGN are formed from magnetic systems, and that the magnetic field participating in their formation is partially dragged all along the jets, make polarization observations of their synchrotron emission a powerful tool to test magneto-hydrodynamic and emission models.” (AGN = Active galactic nuclei). https://lnkd.in/ebzBnWGP View in LinkedIn

IT FOLLOWS THAT. “Since flat space-time is well-known, any observable effects should be well-known as well.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

UNIMAGINABLE SCALE. “Active galactic nuclei are powered by supermassive black holes that accrete matter and are capable of forming pairs of relativistic jets that can extend up to distances far larger than the size of the host galaxy.” https://lnkd.in/ebzBnWGP View in LinkedIn
