i will have to start spending more than 24 hours a day on steemit soon , maybe you know any superheroes who can bend time a little ? barely got through my replies, then i think i got through the backlog on your feed and up pops another one ... so i better get through this one
first of all : cosmic rays aren't just energy like fotons, they have actual atoms in them ? probably not molecules given the high energy and whatever forces they encounter on the way so a cosmic ray is in fact a jet of matter containing actual elements that got erupted from a distant part of space ?
This makes it somewhat alike (in my strange imagination) to scientists drilling a hole in the north or south pole and extracting a long cylinder of ice to "travel back through time as the deeper they go the older the materials frozen in the ice will be"
very different thing but similar principle ?
i'm still not convinced at the actual chance after i read it would take a light-year of lead to catch only half the neutrinos so the chance at catching even one in a small dot like the whole planet earth (if that were the detector) are extremely small but here one got detected - indirectly - due to the light effect that can be observed ?
The blazar is (only detected when directed at earth, makes total sense there, the problem with wikipedia too is you have to click once every three words if you havent really studied the matter for a living, right) the core of a whole galaxy, a super(supersuper?)massive blackhole , so stuffed it can't gobble up all the matter that comes at it so it shoots out in jets (the size of half a galaxy or something?) which are
as i didnt understand before actual jets of matter containing actual elements
makes it sound like a cosmic recycling factory :p
