Does infinity really exist?  Our universe appears to be bound by
a finite set of laws, yet we often talk about things that go on
for an eternity. "Infinity" is a strange idea. But it's crucial
if you want to understand anything from philosophy to
mathematics. Here’s why.  There are three broad domains where
infinity can be applied. It’s used as a conceptual tool to help
us describe the properties and values of objects and processes,
it’s an important notion in philosophy, cosmology and
metaphysics, and, of course, it’s crucial to mathematics. Let’s
take a look at each of these in detail.  The Totality of
Infinity  We often use the word ‘infinity’ when describing
something that goes on forever. But it can also be used to
describe something that doesn’t go on forever, or for which its
value is absolute.  Take, for example, the use of infinity in
