What does the omega symbol mean?

The omega symbol (Ω) is the 24th and final letter of the Greek alphabet, often representing the concept of "end" or "completion." In various contexts, it is used in science and mathematics to denote ohms in electrical resistance, the set of all possible outcomes in probability, and in cosmology to represent the density parameter of the universe.
