"Another Galactic Magnetic Shock "
Refers to solar physics magnetic shock.
I am not interested so much in the disaster aspect of a large micronova happening, as much as being interested in the reasonable science of the actuality of micronovae, and that the science community has not wanted to consider that Solar Micronova have happened in the past and will happen again.
For the most part, a character defamation number initially happened to marginalize people who have been trying to get the science community to take valid historical data seriously (the person who does these videos and research mostly).
I have noticed many times that the science community does not seem to want to consider long term cyclical stuff that happens in the Solar System and Galaxy. Ordinarily, it seems to be geologists who are doing the pushing for people in other fields of science to take a look at long term cycles for their consideration - not only in climate change models but also in relation to activity in our own solar system and its influence on our planet.
Perhaps it takes some time for the information to settle, once introduced before interest develops?
