Given recent history, I'd dare say the number one is certainly possible. It seems like an alternate reality has been happening in my world since about 2008.
I suspect that a great number of the recent advancements in physics have been appropriated by the military and it may be a long time, if ever, that they are made public.
Funny how demonized mercury has become in the past 50 years. Not that it doesn’t deserve it, but it does neatly coincide with the advances being made in mercury plasma in relation to it’s effects on gravity.
Just saying.
