Default Back to supernova geometry

The issue thankfully resolves the notion of whether galaxies came first or individual stars and solar systems.

The central theme of the evolution of the solar system is that supernova events are not necessarily the demise of the progenitor star but rather a transition phase which gives rise to a solar system with planets and satellites, comets and meteors.

As solar systems are still seen to be developing in isolation while traveling around the Milky Way centre, it removes the uncertainty as to whether planetary formation is a thing in the past but rather a normal function of evolution within a galaxy.

The usual dreary silence is hardly a substitute for the use of logical and progressive reasoning which takes physical considerations into account but having been drawn into making conclusions since working with the geometry of stellar evolution before its rings were actually observed, it is really lovely to see the concept blossom with imaging.
