Infinity is normally related to a never ending number but it's not infinite or its plural infinity is a paradox because it represents a never ending number but it is also above all numbers so it is and is not a number thus it is a paradox. To me there is only two things that represent infinity and those two things are mathematics and human stupidity.

The mathematics part is focused on how people think about mathematics, people like Albert Einstein had a brilliant view on mathematics and physics and the same view that had perplexed many people but to them they wanted to do greater find more things out. The Evolution of mathematics shows that if someone views it the right way they can create a new type of mathematics and thus mathematics can be infinite because it feeds off of people's views and many people can have multiple views it just depends on how they live their life. Infinity is also implemented into mathematics to represent a sequence that can not be physically possible to represent without infinity.

The human stupidity part is focused on how social qualities can change people into idiotic mindless people who do very dangerous things just to seem "cool" and this is a function in the human brain that tells you to get friends and impress them but they're not your friends if someone "cooler" came around they'll just be friends with them instead of you and I have experienced this and it's not a good thing. People want to look "cool" so they do things that violate safety procedures that are placed to keep people from dying but this part of the person's brain says it's okay to do it while natural urges try to fight against it and people die because of it and families become devastated once they recieve the news of what has happened to a family member all because their "friends" dared them to.
