Quadrillion Quintillion Sextillion Septillion Octillion Nonillion Decillion Undecillion Duodecillion Tredecillion Quattuordecillion Quindecillion and the list will go on.......
I thought 6 was hextillion instead of sextillion. Kinda like hexagon. Anyways, I looked up some others 16 sexdecillion 17 septendecillion 18 octodecillion 19 novemdecillion 20 vigintillion
Theoretically, this will go on forever. Like calculus, you can see about visualizing infinity - but still a concept we can somewhat grasp and deal with, such as grasping through calculus the concept of limit at infinity. It blows the mind that humans can still find ways to deal with infinity in math! Anyhow.. reverse that question, what's the smallest number!
Infinity is more of a philosophical concept rather than something that truly exists. In other words, every number and/or boundary that you can not name YET should be called infinity, but if you break that boundary tomorrow .. infinity definition's destroyed or ..?
Actually - infinity is not a concept, it does exist. If I can post this link on infinite limits of vertical asymptotes (https://www.studypug.com/calculus-help/limits/infinite-limits-vertical-asymptotes) - you can see via the graphs, that calculus graphically and mathematically represent the concept of when something approaches infinity, thereby proving that it exists. In essence as a mathematically derived function - what happens if variables in the function approach infinity, the conclusion is actually finite. Mind boggling, but extremely intuitive. I literally had the lecture this week
