| Jan 3, 2024 at 21:50 | comment | added | user14111 | Being a nonrepeating decimal DOES NOT MEAN that it contains "all possible number combinations." For example, $0.383883888388883888883888888\dots$ is an infinite nonrepeating decimal, but it does not contain "all possible number combinations". It is known for a fact that $\pi$ is a nonrepeating infinite decimal. It seems plausible that it contains "all possible number combinations" but nobody knows. | |
| Jan 23, 2023 at 1:27 | comment | added | nadapez | It is not only unknown but also maybe is unknown if it can be prooved or dosprooved at all. I guess it cannot be prooved. Also can be prooved that it cannot be prooved? | |
| Mar 12, 2022 at 22:28 | comment | added | Pawan | So pi had a breakup with zero long back and they never did patch up. Just take 100 or 1000 or 10000 or any multiple of 10 except 10 :) | |

| Sep 3, 2015 at 16:53 | comment | added | Jay | Regarding "and the answers to all the great questions of the universe", the answer is yes, of course, at least in base 10! Digits 92 and 93 in the decimal expansion (not counting the integer part) are "42" which, as you know, is The Answer to the Ultimate Question of Life, the Universe, and Everything: 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342 | |

| Oct 19, 2012 at 22:03 | comment | added | Doug Spoonwood | Can we, in principle, non-arbitrarily decide whether any "yes" or "no" answer to this question ends up as true or false? Could an answer to "does pi contain every finite sequence of digits in a given base?" exist? | |

| Oct 18, 2012 at 22:51 | comment | added | Aaron Mazel-Gee | Even if this were true, it'd be impossible to use it to tell the future or anything -- at best, you could piece together the (undoubtedly infinite) list of possible sequences of events, but you'd still have no way of knowing which one is the right one. | |

| Oct 18, 2012 at 17:44 | comment | added | Erick Wong | The assertion is strictly weaker than normality. It only says each string occurs once. This implies infinitely many occurrences but not equidistribution. | |

| Oct 18, 2012 at 14:41 | comment | added | Chris Eagle | It's not just the assertion that $\pi$ is normal. It also asserts that it is normal because its expansions is infinite and nonrepeating. And that's just plain false. | |

| Oct 18, 2012 at 14:40 | comment | added | André Nicolas | This is the assertion that $\pi$ is base $8$ normal. Whether it is true is not known. But it is known that "most" numbers are normal to every base. | |
| Oct 18, 2012 at 14:40 | comment | added | Albert | but it is easy to construct a number containing all finite sequences of numbers : consider 0.123456789 01 02 ... 99 ... 001 002 ... 999 0001 0002 ... 9999 etc | |

| Oct 18, 2012 at 14:39 | comment | added | Giovanni De Gaetano | It makes sense as a mathematical sentence. The truthness of it, in specific of the fact: "every possible number combination exists somewhere in $\pi$" is not clear as crystal to me. But perhaps an expert can say something about it. | |
| Oct 18, 2012 at 14:38 | comment | added | picakhu | This is unknown. All that is known about $\pi$ is that it is transcendental. askamathematician.com/2009/11/… | |
