“THE RELATIVE GEOMETRY is defined by the configuration of the present obstacles, and by the interaction properties at the quantum level. In this, light just happens to have two roles, first as one example of information flow (information exchange with massless properties) and secondly as light rays delineating the metric.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

THE UNKNOWN. “However, the physics of galactic dynamos is far from being understood.” https://lnkd.in/gA4b9wZV View in LinkedIn

SPIRAL DYNAMOS. “Spiral fields were also detected in galaxies without optical spiral structure and in circumnuclear gas rings. This indicates the action of dynamos in rotating galaxies, where the Coriolis force organizes turbulent gas motions, amplifying a weak seed field and generating coherent field structures.” https://lnkd.in/gA4b9wZV View in LinkedIn

THE GYRES. “Radio observations of polarized synchrotron emission showed that the large-scale field structures in almost all nearby galaxies are spiral with pitch angles similar to those of the optical spiral arms.” https://lnkd.in/gA4b9wZV View in LinkedIn

TIDAL WAVES. “Structure formation led to strong intergalactic shocks.” https://lnkd.in/gA4b9wZV View in LinkedIn

NO EMPTY SPACE. “All of “empty” space in the Universe may be magnetized. Its role as the likely seed field for galaxies and clusters and its possible relation to structure formation in the early Universe, places considerable importance on its discovery.” https://lnkd.in/gA4b9wZV View in LinkedIn

UNDERLYING FABRIC. “The search for magnetic fields in the intergalactic medium (IGM) is of fundamental importance for cosmology.” https://lnkd.in/gA4b9wZV View in LinkedIn

NEW TOOLS. “The new generation of radio telescopes will open a new era of magnetic field studies.” https://lnkd.in/gA4b9wZV View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the theme of magnetic forces. The Newtonian idea of space was a cold dark empty vacuum. Today, we believe that there is no such thing, but rather it is a dynamic cauldron of matter being created and destroyed bathed in a highly dynamic liquid of interacting forces. https://www.forbes.com/sites/startswithabang/2020/11/17/quantum-fluctuations-were-experimentally-proven-way-back-in-1947/?sh=2aaf19d33e0e View in LinkedIn
