Spain to New Zeland = cool
I was going to search for this link after Stuart's comment about a Globe being better than Google Earth for this reason ;)Quote:

In 1966, mathematician Paul Cooper theorized that the fastest, most efficient way to travel across continents would be to bore a straight hollow tube directly through the Earth, connecting a set of antipodes, evacuate it (remove the air), and then just fall through. The first half of the journey consists of free-fall acceleration, while the second half consists of an exactly equal deceleration. The time for such a journey works out to be 42 minutes. Remarkably, even if the tube does not pass through the exact center of the Earth, the time for a journey powered entirely by gravity always works out to be 42 minutes, as long as the tube remains friction-free, as while gravity's force would be lessened, so would the distance traveled at an equal rate.[5][6] The same idea was proposed by Lewis Carroll in Sylvie and Bruno, volume 2, chapter 7, without calculation.
Certainly a Big ass hole.
Kewl, so if I lived just south of Prince Albert National Park in Sasquatch, Canada and fell through the earth... I'd have my very own island! lol
has anyone heard how big it is yet? i wanna explore[Beer]
I never see follow ups on these sink holes. Probably because third world countries have better crap to do than looking around in holes. heh.

Spelunking? Does it still count as slelunking if the "cave" is big enough to play a game of baseball in it?Quote:
