I heard the term "New Impossibilities" somewhere and it kind of struck me...  What an interesting idea.  If there are new impossibilities, wouldn't that imply that there were old ones?

It would seem to me that impossibilities are never new.  They are, in fact, just undiscovered.  After all, impossibilities would have entirely to do with the physical realities of things, particularly if you believe that people and their emotions and whatnot are entirely based in the physical... which, in fact, is exactly what I think.

This is interesting because it is kind of depressing in a way.  There are a whole variety of impossibilities that are like stones in the ice cream.  They are there, there's nothing you can do about them, except to do your best to eat around them, or miss one accidentally and break a tooth.

Yet, if you think of it another way its somewhat reassuring.  In time we will work our way through many, and possibly even all, of these impossibilities.  Perhaps one day we will have them all sorted and mapped out, know exactly what we can and cannot do, and be allowed to live out the rest of our time as humanity somewhat more peacefully knowing that certain things simply aren't possible, and that we should focus our attention somewhere else.
