Galactic Road Map

June 29th, 2008

SpaceIt’s a situation I’ve read about in at least two science fiction books. You’re kidnapped by aliens and transported away from Earth. You heroically manage to win your freedom but then tragically realize you have no idea where Earth is. (Given a map of the Milky Way Galaxy, I defy you to point out the general location of Earth. Can’t do it, can you?) And it gets worse—for all you know they may have taken you to a totally different galaxy. Well fear not, intrepid Chad’s News reader. Should this happen, all you’ll have to do is whip out your “Location Earth Dog Tag” and you’ll be back home before you know it. There’s even a guarantee: “Should you ever be abducted by aliens while wearing Location Earth Dog Tags and not returned safely to Earth you will be entitled to a full refund of the purchase price.”

Update: After doing some investigating, it turns out the dog tag is missing some crucial information. There is supposed to be binary information along the pulsar lines, indicating the periods of the pulsars. Looking at the picture of the dog tag, I don’t see that data. Additionally, even if the binary numbers existed, they specify the period as a multiple of the hyperfine transition period of hydrogen (the spin-flip frequency). That fact isn’t included on the dog tag either. Sigh…
