    Draw a Line Through the center of the Earth.....

    from your current position and you get the antipodal position, or reciprocal of your location on the other side of the planet. Essentially, it's 180 degrees from your current position, no matter which direction you travel, like the North and South Poles are antipodes.

    My antipode, here in South Florida calculates to 27 degrees, 16'516"South latitude, and 99 degrees, 36'58" East.

    I'd be out in the Indian Ocean, SW of Australia, about 1,134 miles from the beach in about 14,954 feet of water for my antipodal.

    Where are you? To calculate this, you simply transpose the latitude from north to south and then subtract 180 from your longitude. It's not as hard as you might think.

    Wolfram Alpha has a neat calculator you can use if you don't want to crunch the numbers yourself, but if you've ever wondered what is exactly on the opposite side of the Earth, relative to you, here's your chance.

    I remembered seeing a page that does this. Google found it:
    Map Tunneling Tool.

    Portugal <--> New Zealand.

    ~~~~

    I have the free SkEye app on my android tablet (or use it on android phones). Hold the tablet up to the sky, and it shows a sky map in that direction. But it's weird to aim it at the ground and see constellations and planets over on the other side of the world.

    I read a novel (Generation A by Douglas Coupland) that had a minor theme of anti-podes. Coordinated through social media two people in the rare places on earth where you could do this, like Spain and New Zealand, would simultaneously place slices of bread at predetermined antipodal GPS coordinates thereby making an Earth sandwich. They would video this and post the paired videos.

    I'm not sure you could dig in a completely straight line. Maybe you'd end up in China anyway.

    Gravity Trains. These journeys, by gravity fall, all take the same amount of time, even if the line doesn't go through the center of the earth.

    For example, The Alameda-Weehawken Burrito Tunnel
    from the article:

    Who can imagine New York City without the Mission burrito? Like the Yankees, the Brooklyn Bridge or the bagel, the oversize burritos have become a New York institution. And yet it wasn’t long ago that it was impossible to find a good burrito of any kind in the city. As the 30th anniversary of the Alameda-Weehawken burrito tunnel approaches, it’s worth taking a look at the remarkable sequence of events that takes place between the time we click “deliver” on the burrito.nyc.us.gov website and the moment that our hot El Farolito burrito arrives in the lunchroom with its satisfying pneumatic hiss.

    ...

    The tunnel opened to great fanfare in 1933, with a congratulatory message in Morse Code flashed by powerful searchlight from the San Francisco end to waiting dignitaries on the New Jersey side. It was already obsolete. The first regular mail shipments sent from San Francisco in the spring of 1934 had to compete with the sophisticated air mail system that had grown up during the tunnel’s long construction.

    ...

    The globetrotting Cavanaugh was a fanatic of the recently-invented Mission burrito but bemoaned being unable to get it anywhere outside of San Francisco. Examining blueprints of the defunct mail tunnel on a flight home to New York, Cavanaugh became intrigued by the coincidence in size between a foil-wrapped burrito and the diameter of the old transcontinental mail tubes. By the time the plane landed, he had come up with an audacious plan.

    Cavanaugh realized that the intense heat of the transit that had so beleaguered mail service would actually work to his advantage in a burrito tunnel. The burritos could be stored frozen on the Western end and arrive fully heated through in New Jersey. Furthermore, advances in electrical engineering meant that containers would no longer have to be propelled by compressed gas. The burritos already came conveniently wrapped in aluminum foil - it would be trivial to accelerate them with powerful magnets.

    I remember doing that back in school. The Los Angeles area ended up being in the western Indian Ocean, south of Maurituis/east of Cape Town, South Africa. I knew it wasn't in China (China's above the equator) but my guess at it being near Perth, Western Australia turned out wrong, too.
    Are we having fun yet?
