The symbol "\infty" represents the concept of infinity, which refers to something that is limitless or unbounded. In mathematics, it is often used to describe quantities that grow without limit, such as in calculus when discussing limits or infinite series. Infinity is not a number but rather an idea that helps us understand the behavior of numbers and functions as they approach very large values. Eternity, often associated with the concept of time, refers to an infinite duration without beginning or end. In philosophy and theology, eternity is frequently discussed in relation to the nature of the universe, existence, and the divine. It suggests a state that transcends temporal limitations, allowing for a perspective that encompasses all moments as one continuous experience.
