@tcc.andrew: Graham's number is a mind-bogglingly massive number that serves as the upper limit for a specific problem in Ramsey theory (a branch of mathematics). It is vastly larger than other famously huge numbers, like a googolplex or Skewes's number. To put its scale into perspective, the observable universe is too small to hold a standard digital printout of Graham's number, even if you could pack one digit into every single Planck volume (the smallest possible unit of space). In fact, if you tried to write down just the number of digits that Graham's number has, you would run into the exact same problem—the universe wouldn't have enough room. Even repeating this "count the digits of the digits" process more times than there are Planck volumes in the universe still wouldn't give you a number small enough to write down. Because of this, it is impossible to express Graham's number using standard exponential towers (like a^{b^c}), even though the number itself is ultimately just a giant power of 3. #tcc #edit #rampage #truecringecomunnity #fyp
