A more thorough explanation:

Term: sine numero
Definition: Sine numero means "without number" in Latin. It refers to something that is countless and has no limit. Examples: The stars in the sky are sine numero. There are so many stars that we cannot count them all. Another example is the grains of sand on a beach. There are so many grains of sand that it is impossible to count them all. Explanation: The examples illustrate the definition of sine numero because they both represent things that are too numerous to count. The stars and grains of sand are both without limit and countless.
