It takes the Earth, and its mass, to convert the neutrino flux we have now,
into muons (which we can detect). No, there is no way to use something

I have no doubt that if I kept persuing, I could have had another round of "will answer later, have already answered, not going to answer", but by that time, the point had long since been made: David invites questions, demands them even, but when those questions *he invited* and *promises to answer* come, he - for whatever reason - fails to answer them in any sort of reasonable way. ... My thoughts are that David's adherance to Thiering's theories is a type of fundamentalism, much like any other sort of person with fundamentalist beliefs and his reaction to those who don't see the 'brilliance' of Theiring as he does, who don't have the life changing reaction he did to her work as he did, and to those who can find the logical flaws in her work have much in common with the types of reactions fundamentalists have to those who have not 'seen the light' of their particular belief system. ...
