Names of larger numbers, however, have a tenuous, artificial existence, rarely found outside definitions, lists, and discussions of how large numbers are named. Even well-established names like sextillion are rarely used, since in the context of science, including astronomy, where such large numbers often occur, they are nearly always written ...
The decay time for a supermassive black hole of roughly 1 galaxy-mass (10 11 solar masses) due to Hawking radiation is on the order of 10 100 years. [7] Therefore, the heat death of an expanding universe is lower-bounded to occur at least one googol years in the future. A googol is considerably smaller than a centillion. [8]
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
The highest number in this series listed in modern dictionaries is centillion, which is 10 to the 303rd power. [1] The interim powers of one thousand between vigintillion and centillion do not have standardized names, nor do any higher powers, but there are many ad hoc extensions in use.
Graham's number has a name, and is so far beyond any number expressed in common knowledge notation (such as power towers) that it's retarded. It's greater than Cthulhu and Jesus, and a centillion doesn't even exist next to it. So there. I'm removing the part about googolplex being the largest named number.
Sagan gave an example that if the entire volume of the observable universe is filled with fine dust particles roughly 1.5 micrometers in size (0.0015 millimeters), then the number of different combinations in which the particles could be arranged and numbered would be about one googolplex.
Indefinite and fictitious numbers are words, phrases and quantities used to describe an indefinite size, used for comic effect, for exaggeration, as placeholder names, or when precision is unnecessary or undesirable. Other descriptions of this concept include: "non-numerical vague quantifier" [1] and "indefinite hyperbolic numerals". [2]
The long and short scales are two powers of ten number naming systems that are consistent with each other for smaller numbers, but are contradictory for larger numbers. [1] [2] Other numbering systems, particularly in East Asia and South Asia, have large number naming that differs from both the long and short scales.
