Googol is a very well-known large number, equal to 10100 or 1 followed by 100 zeroes. It is also called "ten duotrigintillion" using the short scale. Show Coined in the year 1920,100 it has become very famous as a generic example of a large number , and is what the field of googology and the search engine Google are named after. Contents
HistoryThe term was coined by Edward Kasner's nine-year-old nephew, Milton Sirotta in 1920. It was perhaps first published in New Names in Mathematics (1937). The name was most likely influenced by name of the title character of the American comic strip Barney Google and Snuffy Smith, which was very popular at the time. Barney Google's name was in turn inspired by Vincent Vickers' 1939 children's book The Google Book. In 1998, the search engine Google was founded, which was named after this number. Their company being named after a large number represents the enormous size of the internet. PropertiesThe googol is equal to ten duotrigintillion in the short scale, or ten sexdecilliard in the long scale. Googol can be expressed as {10,100} in BEAF, or as E100, E100#1, or E2#2 in Hyper-E notation. Sbiis Saibian has given the alternative name guppyding. Aarex Tiaokhiao coined the names unoohol, 100-noogol, and booiolplex for this number. Username5243 coined the name goodolplex for this number, and it's equal to 10[1]10[1]2 in Username5243's Array Notation. SuperJedi224 coined the name decigol for this number. Sizeedit | edit sourceThere are a mere 1080 elementary particles in the observable universe, so googol has little use when measuring real-world quantities. However. it is still much less than the number of Planck volumes in the observable universe (which is about 10185), so it still has some real-world meaning. Sbiis Saibian showed that a googol particles in a tightly packed sphere would still have a diameter of 5.6 quadrillion meters, or half a light-year. A cube with edge length 35mm contains about a googol Planck volumes. Googol is comparable to some numbers produced by combinatorics. For example, 70 factorial (the number of ways 70 distinct objects can be arranged in a row) is about 20% larger than 10100. A googol seconds is about a sexvigintillion (1081) times the estimated age of the universe. A googol angstroms is approximately 100 trevigintillion light-years. It takes approximately 317 novemvigintillion years to count to a googol one integer at a time. Counting by googols, half googols, or duotrigintillions, of course, one could count there faster but it is not considered kosher in hide-and-seek or googology. The time it takes for the black hole TON 618 to fully decay due to hawking radiation is about a googol years. Cultural impactThe definition of googol, googolplex, and similar numbers eventually branched into the field of googology, the study of, nomenclature of, and creation of notations for large numbers. Larry Page and Sergey Brin, the founders of the Google search engine, named their company after a pun on googol, as their goal is to cache the mass of data that makes up the World Wide Web. Googology Wiki has a tongue-in-cheek goal to reach 10100 articles, which is probably impossible. Googol was the subject of the £1 million question in a 2001 episode of the British version of the quiz show Who Wants To Be A Millionaire?, where contestant Charles Ingram cheated his way to the jackpot with the assistance of an aide in the audience.
MathJakob 1615 Just curious, for a start I don't think there is enough hard drive space in the world to document the number but if a computer could printout 100billion 0's a second, how many years would it take before the computer had printed out the full number?

SteamKing Staff Emeritus Science Advisor Homework Helper 12,8091,670 The googolplex = 10^(10^100)
MathJakob 1615 You're not listening to what I'm saying... I'm not talking about printing the number out onto physical objects, I said this many many times. I simply want to know, if a computer can read 100 billion 0's per second, then how many years will that computer take, until it's read through the entire number. Last edited: May 10, 2013
phyzguy Science Advisor 5,0542,054 It's not that hard. A googolplex is 10^(10^100). If you print out 10^11 zeros per second, then it will take

phyzguy Science Advisor 5,0542,054 My mistake. So let me re-do my estimate:
Brian121268 10 so that's 30 sexvigintillion years, (3,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years) or 1/10 novemvigintillion seconds, (100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 seconds) if the math is correct. according to http://bmanolov.free.fr/numbers_names.php Last edited: Jan 27, 2016 How many years is a googol seconds?A googol seconds is about a sexvigintillion (1081) times the estimated age of the universe. A googol angstroms is approximately 100 trevigintillion light-years. It takes approximately 317 novemvigintillion years to count to a googol one integer at a time.
How many Googles are in a googolplex?A googol is 10 to the 100th power, which is 1 followed by 100 zeros. While this is an unimaginably large number, there's still an infinite quantity of larger numbers. One such number is googolplex, which is 10 to the power of a googol, or 1 followed by a googol of zeros.
How many 0 does a googolplex have?It consists of 10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 volumes, and each volume contains 1 000 000 zeros of the number googolplex.
Is googolplex or infinity more?Googolplex may well designate the largest number named with a single word, but of course that doesn't make it the biggest number. In a last-ditch effort to hold onto the hope that there is indeed such a thing as the largest number… Child: Infinity! Nothing is larger than infinity!
