There is a petition on Facebook to define the number prefix for 10^{27} as “Hella.” Yeah, that’s a big number: a one followed by 27 zeros, or 1,000,000,000,000,000,000,000,000,000. Coincidentally, the universe is estimated to be 0.88 hella-meters across. That’s hella big, almost… ;-)

To explore how big that really is, take a look at the Scale of the Universe.

**Update**. Okay, that wasn’t very clear. The number 10^{27} already has a name; it’s octillion. Hella would be the number prefix for an octillion units, like kilo is the prefix for a thousand units. In other works, an octillion meters would be 1 hella-meters. I edited the post to clarify.

Hat tip: All Facebook.

So that implies the universe has an end….what does the end look like? What is beyond the end?

There are space monsters there (and a brick wall). ;-)

Is that similar to the wall between San Diego and Tijuana?
