Yes, fascinating.

Any clue to the number of nutrinos in existence? Or say the distribution of them, from the very old to the ones spitting out of the sun?

Well, for fun I did a rough calculation of the number being emitted from the sun every second, based upon the wikipedia figure that 65 billion or so strike every centimetre of the earth (facing the sun) every second. Obviously it is wildly inaccurate but the result was

1.82804300229627e+38

as an int that is

182,804,300,229,626,770,000,000,000,000,000,000,000

neutrinos per second from the Sun.

I left in the spurious significant digits because they kind of help ram home how large a number it really is ..
