[ WP ] The alien `` megastructure '' recently found around KIC 8462852 actually carries a message ... a prophecy ... a warning .

 Ruth stared at the results of the detector. 
 
 There had to be a mistake here, there had to be. Was someone pranking her? There was no doubt that the computer was detecting a radio signal coming from KIC 8462852. It was repeating, roughly every nineteen seconds. 
 
 Of course this did n't mean anything. Her department was very well known for practical jokes. Which researcher had programmed interference into the signal? Was it David, trying to make her look a fool after she announces signs of life, only to see it proven to be a computer error? Worse, was it her boss Vince, looking for an opportunity to make her look the fool so he could sack her? 
 
 She resolved to check this more thoroughly. Back to the source code. Ugh. Ruth *hated* programming.

 It was n't until three hours of peering at code unearthed no trojans that Ruth realised she was onto something. There was a radiowave source, around 452 Mhz, an energetic microwave radiation, and it was repeating just a bit more frequently than every ten seconds. 
 
 SETI researchers had long expected that the hydrogen line - a form of radiation caused by hydrogen atoms becoming excited at around 1420 MHz - was the most likely frequency for any form of communication. 
 
 Ruth knew that as a scientist, her first duty was to look at plausible hypotheses rather than invoking aliens. She'd spent the whole previous month mocking people who shared clickbait headlines about KIC 8462852 on social media. But a part of her hoped that the ridiculous headlines held truth. 
 
 She made a deal with herself. Spend a day modelling potential natural sources for this repeated message on this frequency - pulsars, even micro black holes, and she could spend a day looking at the alien hypothesis. 
 
 Discipline was never her strength, so the alien approach came first.

 Constants. SETI researchers always emphasised constants. The hydrogen line did n't depend upon whether the recipient of a message measured frequencies in inverse seconds, inverse minutes, or inverse GrokTime units. The speed of light - or more accurately, the speed of causality - was the same whether you described it in kilometers per second, miles per year, or Creks per Groktime. 
 
 But 452066000 oscilations per second? That matched none of the constants of the universe. And 19 seconds? Even if there was a message, it seemed aimed at recipients that understood a language she did not know. 
 
 Four more constants to consider. e, the constant from calculus. The square and cube roots of 2. And Pi. All numbers that anyone with an understanding of mathematics would have to understand. All dimensionless constants. 
 
 What was that frequency multiplied by Pi anyway? Mental arithmetic had always been her strong suit. Ruth carried out calculations and her heart skipped a beat. No. It could n't be. 
 
 She checked again to be sure. 
 
 The emission coming from KIC 8462852 was being sent out on a frequency exactly Pi times slower than the hydrogen line. 
 
 Hurriedly, she interpretted the signal in binary and saw a string of 1s - over six million of them - followed by a mixture of 0s and 1s, and finishing - after more than four billion entries - 4294967297 entries in total - with another six million 1s. Then another 4294967297 entries. 
 
 This find - this find was huge. This could n't be from anything but an intelligent source.
