@camlok,
I've never pretended to be an expert and you know it. I'm relying on logic and a decent understandiing of thermodynamics (the laws governing the behavior of heat and more generally energy in gasses, liquids and solids), chemistry, including metals, water and saline solutions of course, minerals and biochemistry, alm part of what I studied in depth at college and university.
For the record, Farmerman knows much more than I do in chemistry, geology of course, and paleontology. He's also practicing his trade while I moved out of these fields so his knowledge is deep and current while mine is an old and rusty school exposure.
IMSHO I still know more than Farmerman in biology, genetics and biochemistry. (throw in geopolitics for good measure)
I also know the facts of the matter reasonably well, because I was living in NYC at the time, went downtown on 9/11 to see it with my own eyes, and read the news a lot afterwards.
I have my own doubts here or there with the "official account", like I suspect we all have. But there are very different from yours. And that's the thing: we both have an alterative theory but not the same one.
