a logical shot.... Hey, here's a chance to shoot me down by giving me an endless list of reasons why this is the dummest idea of all time! Could netrinos actually be the missing graviton particles? In my nieve mind they qualify in most respects.. 1. hardly interact with matter at all. 2. Vast quantitys of sun's netrinos are spose to flow through the earth and throughout the rest of the solar system. Only drawback is that current theory reckons non nuclear-active bodys don`t produce enough of them. So how loose is current theory on cold-body netrino production? 100% certain no way?
