If nothing else, at the very least this thread has further reinforced just how little scientific know-how sceptimatic possesses.
It's been a long, long time since I've seen such widespread ignorance of mathematics, physics, chemistry and science in general—probably in the fifties in high school.
One could possibly presume from sceptimatic's scientific ignorance of the earth sciences that he's simply a major troll having a good laugh at our attempts to explain even the basics to him, or that he's suffering some sort of delusional disability. I simply can't believe that anybody living in the 21st century could be living their life as prescribed by Middle Ages science, or with the mindset of a 12-year-old kid.
And if he is serious about all this stuff, then he's yet to define the units of measurement for his theoretical "denpressure" and let us know whether it's a scalar or a vector quantity. I've asked him several times, and each time he's avoided answering.
So I can only agree JimmyTheCrab—this post has been severely devalued with sceptimatic's endless bullshit input.
