You mentioned that it was believed that there was an "element zero" because of the characteristics of the solar corona, which were soon to be disproved. This disproves that there was no element zero present in the solar corona, but can this disprove that there definitely isn't an element 0? In other words, can the absence of a substance in one place rule out its existence? Mendeleev often left open spots on his periodic table (eg; eka-aluminum (gallium)) and he was right about that...

I like on how you ruled it out completely when in theory it should exist in neutron stars and would be radio active. That is like claiming that E-119 does not exist because we haven't seen it.

IMO bitcoin would fit nicely into the element 0 box.
