Yes, in mathematical terms, infinity is forever. It represents a quantity or concept that is without any bound or end.
While the concept of forever in interpersonal relationships, as mentioned in the reference, is often a hope or desire, in mathematics, infinity is a well-defined concept representing something limitless. For example, the digits of pi (π) continue infinitely without repeating. This endless nature is the essence of infinity. The symbol ∞ is commonly used to represent it.
While the practical application of "forever" in everyday life might differ from the mathematical definition, the core concept of endlessness remains consistent. Therefore, in the context of mathematics and its abstract definitions, infinity is forever.
