What is infinity?

Complex answer to a simple question…. 

Miriam Webster's definition:
in·fin·i·ty (noun) \in-ˈfi-nə-tē\ is

1. the quality of having no limits or end: the quality of being infinite 
2. a space, amount, or period of time that has no limits or end
3. a very great number or amount

From my understanding of the definition above, infinity can be broken into 2 different ideas. Infinity in math. And infinity in life. I see infinity in math all the time. Just as the definition suggests, infinity shows something that has no limit or end. I  write , for example, to represent the part of a function that never ends- in the same way 2 parallel lines will never meet, as they go on forever, the 2 ends of the 'U' in the parabola of a quadratic graph or the '/' in a linear graph will continue to + or -. We also see infinity rules represented in the popular television ad for AT&T when they ask little kids what the biggest number they could think of was. The answer started with . Then went to +. Then ended with x. Infinity was representing the bigger and bigger numbers. But, although I write  in math problems… infinity isn't a number but a concept which is seen in this case. In the popular novel, The Fault in Our Stars, John Green wrote, "Some infinities are bigger than other infinities." The quote, of course can be translated into the mathematical sense, reflecting the question the kids on the AT&T ad posed, because we can't measure infinity. But, what does that really mean? In not a math sense, but a life sense. The quote seems to express that every person's experience of what infinity is, differs. The more we look at infinity, the more we see that everything seems to have a theoretical infinity. Time is infinite.  The sky is infinite. Experiences and memories are infinite. The human body is infinite. Life is infinite. John Green's quote, in the context it was written, probably suggested that not everybody lives very long lives. Some shorter lives are "smaller infinities". A similar idea is posed in Stephen Chbosky's Perks of Being a Wall Flower, when he wrote "And in that moment, I swear, we were infinite." In the context of the novel, it shows how some moments are just infinite. Everyone has experienced a time where they felt infinite. A time where they were having such a good time they never wanted the moment to end. Fond memories from childhood are infinite. Listening or playing music is infinite. Art is infinite. These experiences become an infinity where the infinity of the infinity stays infinite. So, what is infinity? Infinity is a concept in it's truest form. Whether we use it in math, or in life, we can see infinity is more than a 'sidewise 8'. Or more than "a very great number or amount". Infinity is in everything. Infinity is everywhere.
