Is Cantor wrong about more than one infinity The odd numbers, just to recap, are eternally half the natural numbers, as they go to infinity. Moving 3 to place 2 ect is basically just adding the even numbers to the odd, if you think of this series with your imagination, or geometrically. The argument from Cantor is that all geometrical objects have the same infinity inside them. If this is true, it upsets saying for sure that the odd numbers are half the naturals. But then I don't see a clear reason why we couldn't say, considering that a circle inside a circle has the same points within it as the outside one, why countable infinities can't be equal to uncountable. If the part can be equal to the whole, as Cantor implies, then anything seems possible. Anyone?
