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 3
