discussing the count of a large number of objects, such as stars in the Observable Universe, the focus is not on calculating their literal quantity down to the last star. In such cases, understanding the order of magnitude is sufficient. It is considered that the number of stars in the Observable Universe is a figure with 22 digits, which is more conveniently represented as one followed by 21 zeros and written as 10 to the power of 21.
Moreover, this is a lower estimate. This means that there could be
as few as
or as many as
1 000 000 000 000 000 000 000,
9 999 999 999 999 999 999 999
In a googol years, the last black holes will evaporate, and our Universe will plunge into darkness (probably). But in general, it's just a beautiful round number with a hundred zeros.
The name of the company Google is a distorted spelling of the word "googol", as the domain with the correct spelling was already taken by the time the company was registered.
