Even in an Infinite Multiverse with Unlimited Possibilities... Some Things Won't Happen.

I've struggled with this one for a while, and I've finally figured it out.

Theorists say that with an unlimited multiverse, comes unlimited possibilities.  In this another universe, you died in that car crash, or you became the greatest whatever that ever was.  With infinity, all possibilities exist, no matter how remote.

Or do they?

Could a dinosaur invent a rifle?  This theory suggests that it happened.  And certainly, if that meteor didn't strike the earth and the dinosaurs evolved intelligence, it did happen, in the realm of unlimited possibilities.

You see it in comedies and movies -- crazy, seemingly impossible things portrayed, because the theories suggest they can.

Or can they?

I struggled with it because I know some things simply aren't possible.  Some things are too ridiculous, contradictory.  In 81 million BC, a dinosaur WITHOUT intelligence, COULD invent a rifle, because of infinite possibilities?

No. that simply couldn't happen.  And unlimited possibilities doesn't mean it could.  And I've finally figured out WHY...

There's something all the science shows failed to show me, although I'm sure most if not all theorists have realized this already.  The formula is NOT unlimited possibilities = everything has happened.

The formula is [unlimited possibilities] x [probability] = everything that can happened.

What's the possibility of a universe that formed exactly as ours did except for a minuscule difference that caused the meteor to miss and dinosaurs to develop intelligence?  Even if it's 0.00..(add # of 0s here)..001%, it has certainly happened in the unlimited multiverse theory.

But what if the probability is 0% outright?  Can a dinosaur without intelligence conceive of, and invent, a machine gun?  If you're really arguing the question, just substitute a dinosaur for a rock, and you'd be crazy to say "maybe".  It's a 0% chance outright.

And it doesn't matter what you multiply 0 by... 10... 100... ∞ you still get "0".  So [unlimited possibilities] x [dinosaur without intellect (or a rock, if you prefer) inventing machine gun] = 0%.  It'll never happen... even if there's unlimited possibilities.

So everything you can imagine cannot happen.  But, as a fun little twist, everything that can be imagined, has been.  So is there anything that has a 0% possibility of even being imagined?

(funny enough, I believe the 1884 book "Flatland" holds the answer to that one.  It's freely available to read on the internet, since it's long been in public domain.)
