The World's Tallest Structure -- or Not?

Much as it would be fun to claim, it doesn't look like Tokyo Sky Tree Tower will be the tallest structure in the world. That honor is debated, and much confused, as discussed here.

It's pretty certain Tokyo Sky Tree Tower won't get the distinction. A few months ago the designers added 24 meters to the plan which is said will make it taller -- at 634 meters -- than a rival structure going up in China. Take that, China!

Meanwhile, the reigning king of skyscrapers of any type is the Burj Dubai, a building that will be a whopping 184 meters taller than our Sky Tree.

Oh, well...
