Would a googolplex people fit in the universe?

Answer 1

A googolplex people could definitely fit in the universe. Googolplex, while a very large number, is also finite. There is a good chance the universe is infinite, depending on which model you follow. The observable universe (the part with light in it), however, is about 93 billion light years wide. If we assume that the average human is about a foot wide (from chest to back, not shoulder to shoulder), and six feet tall, then 4.01 * 1081 humans could fit in the universe. This is no where near googolplex, so your answer would differ depending on your definition of the universe. Note: my calculations involved assuming humans were about a 1*1*6 prism, and could be stacked right next to each other. Additionally, my estimation of the area of the universe is much larger than it actually is because it isn't a perfect cube, like I used in these calculations. However, because the number was so far short of googolplex, this estimation will do. For those of you who do not know what googolplex is, it is one followed by a googol zeros. Googol is one followed by a hundred zeros. So googleplex is 1010000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
