In 2010, college physics student
Austin Sendek started a petition that
requested the International System of
Units make 10^27 (1 octillion) a
‘hella’ meter. According to Sendek,
the diameter of the universe is
1.4 hellameters. Therefore, if the
petition hadn’t been rejected, the
Universe would officially be ‘hella big.’ Source Source 2 Source 3The International System of Units list of current prefixes, established for powers of ten from 10^-24 to 10^24:
