Horizon - To infinty and beyond Part 2 of 6

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.

What if.....we define the largest number as being that number which can be quantified..or to which there is substantial evidence that this number of things exist... then we would have... a largest number!

[mindinflow]

@howlifebegan You can choose for a highest number but than it would be simply a trick for the mind.

Its like choosing a higher number where society will end counting.

But in reality this counting cant stop.

So if we define something being a highest number we are playing as rulers of nature and say we stop researhing here en the the line will end here.

Mathematics is evil!!

I wish the beeb could make a program with more substance than style for once. Though interesting, this program could do without the multiple camera angles and awkward play acting.

That is just so wrong...

@d4nilipe MATHEMATICS RULES!!!!!!!!!!!!!!!!!!

This explains why the universe is expanding, because it is infinite. This hotel thought experiment is really a concept of expansion which results in the birth of a new space, it's the expansion that makes it possible for the new guest or guests to exist there. And according to science the universe is constantly expanding and always has been since our theory of how that expansion started. If this shows expansion is characteristic of infinity and the universe is expanding, it could be infinite.

@dirtydonki In a scale fom 1 to infinity, how much does it hurts ?
