Infinity

Do you think that there is the same amount of even numbers as whole numbers? There actually is, here's why. If you look at this "number line," and you  1--2--3--4--5--6--7--8
multiplay each number by two, you get an even            |   |    |    |   |    |    |    |
number every time. Since there are an infinite amount 2  4   6   8 10 12 14 16
of numbers, there will always be enough evens to match up with the whole numbers! Something that's infinite just keeps going on forever, and ever.
