Ah. Thank you for supporting my point (in the intro, which I just re-wrote) that we don't have good ways to prove that impossible things are impossible. I doubt you meant to do this, but if you think about it, I think you'll see that you did. (:

So, with the assumption in mind that impossibility is subjective and unproven, what monetary goal do you predict most people would FEEL a sense of "impossibility" about? Or, if you'd rather, what goal would YOU feel a sense of impossibility about?

That's what we need in order to make the idea above into an impossible one. (:

Any suggestions on my new introduction?
