Same way as there is an _natural_ number that is not on *any* list you
construct (of natural numbers).
Let suppose you have listed natural numbers:
1: 3
2: 7
3: 99
.
.
Now, in every step lets construct a number by adding them: 3+7+99+...This
number is bigger than any number previously in list (do i have to prove it
to you?). The situation is same as in Cantor's list - he construct a
decimal number in every step that has not yet been on list - but it could
be next or later. It will be different than *any* only if we can go the
list trough, but we can't. Or if we can, then we can go this list too:
1: 0,1000...
2: 0,2000...
.
.
999: 0,999000....
33333.... : 0,3333333333....
And the last row is the answer to other Cantorist who ask where is the
place for the 0,3333333....
There is even place for the pii/10:
3141592653589... : 0,3141592652589...
