Up to date: Answer

The primary 4 digits after the decimal level in $pi$ are 1415. If we convert this utilizing an alphabet cipher ($A=1, B=2, ldots, Z=26$) we get $$ 14|15 rightarrow NO$$ So we’ve got

Q: “Is there a secret message encoded within the first decimals of $pi$?”
A: “NO”

Authentic reply

If we take $pi$ as much as eight digits after the decimal level i.e, $3.14159265$ and use an alphabet cipher ($A=1, B=2, ldots, Z=26$) we are able to assemble the next $$3.14|15|9|26|5 rightarrow C.NOIZE $$ and C-Noize is outwardly a musical artist with some music on youtube.

So perhaps the universe is telling us its favorite kind of music?

Here is my guess

Take the primary 100 digits of pi:
1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679

STEP 1: Based mostly on whether or not a digit is odd and even, convert it to AB format. End result:
ABAAA BBAAA BAAAA BABBB BBBAA BABAA ABBBB BAAAA BAAAA AAAAB ABBBA ABABB AABAB ABABB BBBBB BBBAA BBBBB ABBBA ABBAA ABAAA

STEP 2: This clearly pertains to Francis Bacon’s biliteral cipher (see wikipedia), a long-time favourite means of hiding messages; nevertheless, that is apparantly an unpublished model of the cipher, since some mixtures should not in Bacon’s public alphabet.
The letter sample appears to be like like this, nevertheless (i.e. which letters are repeated and the place and which letters should not repeated in any respect):

12345 673(repeats third letter, so the third letter within the message is repeated)38 9(10)(11)(10)(12) 5(12)9(13)1 (the parentheses are there to keep away from confusion when there are two digits within the quantity)

STEP 3: You will need to know that anagrams had been a major type of cryptography in Bacon’s day (see wikipedia). Thus, once we produce the next gibbberish by means of easy monoalphabetic substitution (see wikipedia)…:

STEP 4: We are able to guess that it’s actually an anagram, and never gibberish. Rearranging the letters and utilizing an “s” as a cease(interval), we get…..
