People are afraid of big numbers because they have no spatial understanding; the largest numbers are beyond comprehension, as the multitude of chess moves or the unfathomable number of sand grains in the desert. Infinity appears impossible to count!
University of Texas computer science professor Scott Aaronson believes the answer to naming the world’s biggest number lies within the deepest paradigm, some of which is solvable by exponentials, language, and sheer imagination:
“When thinking about 3, 4, or 7, we’re guided by our spatial intuition, honed over millions of years of perceiving 3 gazelles, 4 mates, 7 members of a hostile clan. But when thinking about BB(1000), we have only language, that evolutionary neophyte, to rely upon. The usual neural pathways for representing numbers lead to dead ends. And this, perhaps, is why people are afraid of big numbers.”
