A googol YB equals 10^124 bytes, which sparked a discussion on converting this figure into terabytes. Clarifications were made regarding the definitions of a googol (10^100) and a googolplex (10^(10^100)), with some confusion about the notation. The conversation shifted to larger numbers, including Graham's number, which is noted for being the largest number used in a serious mathematical context. Participants debated the concept of infinity and its relation to numbers, while also discussing the origins of the term "Google," suggesting it derived from "googol." The thread included playful banter about the significance of various large numbers and the nature of mathematical definitions.
