These guys are in my crank science bin.

Sorry to be so blunt, but they could at least try to make the story rational.

(invisible intangible matter that doesn't sink downwards when it is "supported" by matter it barely interacts with???)

Give me a break.

I like out-of-the-box ideas, but a reality check would be good.

(Alex, I know everytime I say this, you say "What, like CO2 on Mars?", but I *am* trying to address reality and*do* take note of criticism from my peers.

I find that observational reality is a useful check on the applicability of odd ideas. Anyone can have an odd idea. the trick is to have an odd idea that meets at least 90% of the observational evidence...)
