Which impossible impossibilities have become more than just possible?

For more than several millenia,

some of that which was supposed to be or assumed to be

or believed to be impossible have become,

during the course of all human events,

  not merely possible, or even possibly possible,

but have also become explainable, demonstrateable, actualizable,

enactable, experienceable, achieveable.

Which impossible impossibilities can You identify

that have never and will never become possible?

Which impossible impossibilities can You identify that have become,

 during the course of all human events, possible?

Which would You prefer participating in,

a gratuitously held blogging forum without cash awards and prizes

 or a blogging contest for cash awards and prizes

for a mininimum entry fee of either

$11.11 (if 5,555 Original Members are reached)

or $22.22 (if less than 5,555 Original Members are reached)?

Is the impossible possible?

 What do you suppose a Meaningful Connections Blogging Forum actually is?

Can a guidebook prove, beyond the shadows of all doubts,

that there are at least two presumed impossible impossibilities

that have Now become far more than merely possibly possible?
