A googolplex is a very large number, specifically 10 to the power of a googol (which is 1 followed by 100 zeros).

## Detailed response

A googolplex number is an incredibly large number that is difficult for the human mind to comprehend. It is calculated as 10 to the power of a googol, which is written as a one followed by 100 zeros. To put this into perspective, if you were to write out a googolplex in full, it would take up more space than the known universe.

The term “googolplex” was coined in the 1930s by a nine-year-old boy named Milton Sirotta, who was the nephew of American mathematician Edward Kasner. Kasner had asked Sirotta to come up with a name for a number that was larger than any that had been previously defined.

Famous physicist Richard Feynman once said of the googolplex, “The difference between the approximate number of elementary particles in the visible universe and a googolplex is only a factor of ten or so.”

Here are some interesting facts about the googolplex:

- If you were to write out every possible permutation of the digits from 1 to 9, it would take 3.6 googolplexes worth of paper.
- The number of atoms in the observable universe is estimated to be around 10 to the power of 80, which is still much less than a googolplex.
- In computer science, a googolplex is often used as a theoretical limit for computations. It is considered to be the largest number that a computer could ever process.
- The word “googol” has become a part of the popular lexicon, thanks in part to the naming of the company Google. The search engine’s name is actually a play on the word “googol”.
- The Guinness World Record for the largest prime number ever discovered is a number with over 24 million digits, which is still much smaller than a googolplex.

To give a visual representation of the enormity of a googolplex, here is a table comparing it to other large numbers:

Number | Numeric Representation |
---|---|

Million | 1,000,000 |

Billion | 1,000,000,000 |

Trillion | 1,000,000,000,000 |

Quadrillion | 1,000,000,000,000,000 |

Quintillion | 1,000,000,000,000,000,000 |

Googol | 1 followed by 100 zeros |

Googolplex | 10 to the power of a googol |

## Response via video

Numberphile discusses the enormous size of a googol, which is 1 followed by 100 zeros, larger than the number of particles in the universe. However, a googolplex, which is 10 raised to the power of a googol, is so large that it cannot be written down even if every particle in the universe were used for it. A person or object occupying a meter cubed of space would have roughly 10 to the power of 10 to the power of 70 possible states, much smaller than a googolplex. If the universe were googolplex meters across, there would be repeating volumes of one meter cubed and eventually, an entire observable universe would repeat, highlighting the vastness of the number.

A googolplex is a

number that is 10 to the power of googol, or 10 (10^100). A googol is the number 1 followed by 100 zeroes. Written out in ordinary decimal notation, a googolplex is 1 followed by 10^100 zeroes.

A googolplex is the number 10 googol, or equivalently, 10 (10100). Written out in ordinary decimal notation, it is 1 followed by 10 100 zeroes, that is, a 1 followed by a googol zeroes.

To a mathematician, a googolplex is the figure 1 followed by a googol of zeroes (a googol being the figure 1 followed by a mere 100 zeroes).

## Facts about the topic

**And did you know:**Counting to a googolplex would be even more impossible. We can’t calculate how long it would take, but it’s estimated it would take longer than the age of the universe. As a comparison, counting to a trillion would take roughly 31,709 years, and a trillion is only a 1 followed by twelve zeros!

**It’s interesting that,**Given any reasonable estimate of the size and age of the universe, there’s neither enough space to write all the zeros in a googolplex, nor the time to do so. If every part of the universe were filled with zeros, there still would be nowhere near enough space to hold them all.

**What does googolplex look like in numbers?**

Response will be: A googolplex is a 1 followed by a googol of zeros.

It’s impossible to write out, but in scientific notation it looks like 1 x 1010^100.

Then, **Is googolplex higher than infinity?**

The reply will be: 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**!

In this manner, **How big is a Googolplexian?**

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.

**Is "Googleplex" a real number?**

The response is: In 1940, the mathematician Edward Kasner published the book "Mathematics and the Imagination", in which he popularized the words googol and googolplex which his nephew suggested as names for big numbers. The much larger number googolplex has been defined as 1 followed by a googol zeros. While this number can easily be written as

Simply so, **What are the numbers after a Googleplex?**

A googolplex was originally coined by Milton Sirotta as a continuation of the googol, and suggested that a googolplex should be one followed by writing zeros until you get tired. How many trillions are in a googolplex? Trillion, the next number, is a 1 with twelve zeros after it, or: 1,000,000,000,000.

Considering this, **How many zeros are in a googolplex?** There are 10 zeroes in a googolplex. The number googolplex is bigger than , but there are one tenths as many zeroes in a googolplex than the value of the number 10. I hope this makes sense. This question is kind of strange, since it answers itself.

**Is Googleplex the largest number?**

Answer: What is the biggest number googolplex? Despite having more numbers than atoms in the universe, trying to prove that your integer is bigger than anyone else’s integer has continued through the centuries. The biggest number referred to regularly is a googolplex (10googol), which works out as 1010^100.
