According to many current models of cosmology, our universe is probably finite. As vast and expansive as it is, it could very well be finite and just one of many different universes. But let’s take the idea of a finite universe as an example of why the infinite must exist. In order for a finite universe to exist it must be bounded. However, the very nature of a boundary implies that it divides or delineates between two spaces (i.e., it draws a line between two spaces). If the universe is finite, then it has a boundary where it can go no further. However, this boundary implies that it is separating something from something else. So something else must exist beyond this boundary or limit. Furthermore, the very idea that our brains can so easily grasp the idea of the infinite supports the argument that the idea of infinity is a natural phenomenon. Another example is readily and easily available to our minds: the number line (i.e., the line of all possible numbers). This set stretches to infinity in both directions, negative and positive. This is something we learn at an early age and it is fairly easy to comprehend. Space also seems to be infinite. More precisely, even if our universe is finite, it exists within an infinite space because there must be something that bounds it. And if there are indeed a multiplicity of universes, the space in which all these universes exists is probably infinite.

But what does any of this mean to us? Why is this of any value to us? Well, the fact that the infinite exists in our natural world supports the inference that there is in fact something (and not nothing) in the world. That something can give us hope for a greater meaning. It is possible that there is no greater meaning. But in a world where the infinite exists, an infinite possibility of goodness could exist. That, alone, should provide some consolation for those times when emptiness and nothingness seem more palpable than anything.
