The last 15 minutes or so, really gets into the fine-resolution nuance of what is actually being detected and where they originate. (and how they differentiate them)
“Atmospheric source neutrinos” get created when cosmic rays strike the atmosphere. Concurrently, our Sun is generating neutrinos itself, and the 3rd category are the ones they want to detect; neutrinos produced close to their source and then which travel long distances.

Since they found a flurry, there is a chance one will actually be able to say something about how Blazars’ activity (or orientation) is changing over time. How it correlates with observations of light from the same source. Tuning in the universe in yet another domain. If blazars are binary super massive black holes in merging galaxies, one day such a source might be observed in the domain of gravitational waves too, maybe making it possible to confirm that a bunch of different physics are consistent with each other.

Btw, is it Orion’s left or our left? Oh I see, Orion is standing with his back towards us, so it is the same.

One of the things i learned so long ago about the ‘Scientific Method”
If you can’t test , analyze, repeat the results independently, it’s not science, Like this “neutrinos proven”, like CERN, Higgs Boson proven? bah….
