: googolplex) * ''Mathematics – Literature:'' The number of different ways in which the books in Jorge Luis Borges' The Library of Babel, Library of Babel can be arranged is approximately $10^$, the factorial of the number of books in the Library of Babel. * ''Cosmology:'' In Chaotic Inflation theory, chaotic inflation theory, proposed by physicist Andrei Linde, our universe is one of many other universes with different physical constants that originated as part of our local section of the Multiverse#Bubble theory, multiverse, owing to a vacuum that had not decayed to its ground state. According to Linde and Vanchurin, the total number of these universes is about $10^$. * ''Mathematics:'' $10^$, order of magnitude of an upper bound that occurred in a Skewes' number, proof of Skewes (this was later estimated to be closer to 1.397 × 10316). *''Cosmology:'' The estimated number of Planck time, Planck time units for quantum fluctuations and quantum tunnelling, tunnelling to generate a new Big Bang is estimated to be $10^$. * ''Mathematics:'' $10^$, a number in Names of large numbers#The googol family, the googol family called a googolplexplex, googolplexian, or googolduplex. 1 followed by a googolplex zeros, or 10googolplex * ''Mathematics:'' $10^$, order of magnitude of another upper bound in a proof of Stanley Skewes, Skewes. * ''Mathematics:'' Steinhaus' Steinhaus–Moser notation#Mega, mega lies between 10[4]257 and 10[4]258 (where ''a''[''n'']''b'' is hyperoperation). * ''Mathematics:'' Moser's number, "2 in a mega-gon" in Steinhaus–Moser notation, is approximately equal to 10[10[4]257]10, the last four digits are ...1056. * ''Mathematics:'' Graham's number, the last ten digits of which are ...2464195387, equals 3[3[3[...3[3[3[6]3+2]3+2]3...]3+2]3+2]3 with 64 levels of brackets. Arises as an upper bound solution to a problem in Ramsey theory. Representation in powers of 10 would be impractical (the number of 10s in the power tower $10^$ would be virtually indistinguishable from the number itself). * ''Mathematics:'' Kruskal's tree theorem, TREE(3): appears in relation to a theorem on trees in graph theory. Representation of the number is difficult, but one weak lower bound is ''A''''A''(187196)(1), where A(n) is a version of the Ackermann function. * ''Mathematics:'' Friedman's SSCG function, SSCG(3): appears in relation to the Robertson–Seymour theorem. Known to be greater than both TREE(3) and the TREE function nested inside itself TREE(3) times with TREE(3) at the bottom. * ''Mathematics:'' Transcendental integers: a set of numbers defined in 2000 by Harvey Friedman, appears in proof theory.H.
