The enigmatic concept of infinity has captivated the human mind for millennia, prompting the fundamental question: “Is infinity a number?” This existential inquiry delves into the philosophical and numerical realms, challenging our perception of mathematical boundaries.
In mathematics, infinity denotes an unbounded quantity or a boundless set of elements. For instance, the set of natural numbers (1, 2, 3,…) extends infinitely without a definitive end. Infinity finds practical applications in scientific fields like cosmology, where it represents the immeasurable expanse of the universe, or in calculus, where it symbolizes the limit of a function as its input approaches a specific value.
