You know I know! Ha ha! Just like I knew you'd lay an egg when you read "virtual nano particles", lol. I just quickly strung a bunch of impressive words together in a way... well, just like the guys at companies like TUC do!
*Edit: Just for the record, I learned a neutrino particle can pass through a light year thick chunk of lead and not interact with any of it. Tho I recently learned that highly energized neutrinos from say, a supernova will interact with other particles just from the sheer volume produced and extreme energies involved.
