By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like a perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.

Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more bizarre. In an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you. Older than time, bigger than the universe and stranger than fiction. This is the story of infinity.

  • Take a sheet of A4 printout, 300dpi black & white. Each pixel is one bit, so a fixed size integer with 8.7M pixels can represent anything you could print on that page. If all ideas can be represented on that page page this means there are a finite number of possible ideas in the universe. In fact 300 dpi is quite generous, 100dpi would do! It's trivial to make a computer program to print out all possible pages. We don't need infinite numbers of monkeys!

  • dude, I'm gonna get some shrooms or such and watch this again

  • Dude...No Edge...

  • @vapats1802 Long live the pesky questions. = )

  • @toodance 'invited' to leave catechism, yeah, me too...  :-)

  • Monkey's are not infinate. Say we have 1,000,000 monkeys on earth, do we have enough typewriters to go round?, probably not. My problem lies with the training of the monkeys, it's not possible as the most they can do is get some ants from a tree with a stick.

  • prof. Ziegler, once you've got rid of infinity, do you intend to go about sorting the axioms out?

  • Infinity counted to Chuck Norris, And thus he was born. Then Chuck roundhouse kicked infinity and thus infinity got divided into multiples.

    Hope the new infinities won't start counting either, it might result into multiple Chucks fighting each other. Imagine the amount possibilities that would happen there!

    You guessed right, infinite! So there you have it.

    I heard you like infinity so I've put an infinity into your infinity...

  • THe subject is fascinating...I only wished they dropped the twighlight zone bullshit.

  • btw- Anyone else notice the primary benefactor of thanks when the credits start rolllng?

    So when the narrator says "Implications far beyond the realm of science..", that puts an interesting, little twist into this doc I had previously missed...heh. I'll be darned... I think I remember "no beginning and no end" in catechsm before I was 'invited' to leave (for asking too many pesky questions...)
