The smallest infinity is zero, since it’s the sum of an infinite number of zeros. But can’t you just divide that by 2 to get a smaller one, you might ask? No.

"The smallest infinity is zero, since it’s the sum of an infinite number of zeros."

Zero is not an infinity. Zero is one of the infinite set of integers (... -3, -2, -1, 0, 1, 2, 3,...).

In a decimal format it doesn't matter how many zeros (even an infinite number) are included in 0.00000... It is still the integer zero. Dividing zero by any real number (except zero) still gives zero, no matter how many zeros are including in the decimal format.
