I speculated that iridium may have floated -- I never said it did so -- based on raeding yesterday that radioactive tritium was carried on ocean currents.
And this is an example of your
"ability to recognize practical possibilities, or common sense"?
Could you outline the thought process that takes you from there being tritium in the oceans to iridium possibility floating? I don't see any possible connection at all.
Actually, do you even know what tritium is?
