WRENCHING CHANGES. “Once, the craggy limestone peaks that skim the sky of Everest were on the ocean floor. Scientists believe it all began to change about 200 million years ago – at around the time the Jurassic dinosaurs were beginning to emerge – when the supercontinent of Pangea cracked into pieces.” https://lnkd.in/e6xDEQ2H View in LinkedIn

UNKNOWN LIMITS. “What then is the upper limit of magnetic monopoles in the universe? There is no theoretical basis for expecting either their presence or absence. We have only the philosophical possibility, suggested by the symmetry between electric and magnetic fields in Maxwell’s equations, that if there are electric charges, then why not magnetic charges?” https://lnkd.in/eYiqnNnc View in LinkedIn

NO MAGNETIC NEUTRALITY. “Consider the implications of the universal occurrence of large-scale magnetic fields. They could not exist if magnetic monopoles were abundant. They would be neutralized in exactly the same way that electric fields are neutralized. In that case there would be no induced electric fields either.” https://lnkd.in/eYiqnNnc View in LinkedIn

SO ENDS this second and last weekend on cosmic magnetism. This twist on the usually dull classroom physics of magnetism electrifies the topic into an extraordinarily fascinating theme, with more questions than answers, and highlights that our earth-bound glimpses of this beast are not related to its true nature in the unruly cosmos. https://lnkd.in/eU4GzKqE View in LinkedIn

FUTURE WORK. “More thorough analyses of quantum effects, and curvature, are necessary to determine whether the hypothesis is realistic or not.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

LITMUS TEST. “If the explanations outnumber the assumptions when we are done, we will mark up a success. On the other hand, if the assumptions and special hypotheses outnumber the explanations, we will have to go back and start over again.” (The author, Professor EN Parker, after who NASA named its Parker Solar Probe, the first time NASA had named a spacecraft after a living person). https://lnkd.in/eU4GzKqE View in LinkedIn

GEOMETRIC AGREEMENT. “However, our only non-trivial result is that equilibrated interactions must have a Gaussian fall-off to capture the relations of Euclidean geometry, which coincides with trivial particle diffraction for Gaussian apertures.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

FUNDAMENTALS. “The theory developed in this book is insensitive to whether a locality is populated solely by electric or by magnetic particles. Maxwell’s equations are symmetric in E and B, so that the fields can be interchanged if the charge on particles is interchanged. There would be no large-scale electromagnetic activity and the locale would be a dull place indeed.” https://lnkd.in/eYiqnNnc View in LinkedIn

A HEART OF INFORMATION. “In addition to curvature, a space-time originating in information exchange would be shaped by how matter provides boundary conditions to propagation of information, a scenario which could be compatible with wave-particle duality in particle diffraction.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

AN ELECTRIC UNIVERSE. “The evidence at hand shows a strong prejudice in the universe for electric matter and against anti-matter or magnetic matter.” https://lnkd.in/eYiqnNnc View in LinkedIn
