Jon Stewart Author Interview: 'Blind Descent' Author James Tabor On The Deepest Place On Earth (VIDEO)

The deepest cave on Earth is about 7,000 feet deep -- that's seven Empire State Buildings -- but the people who descend to the bottom are hardly ever spoken about in the way that we laud those who climb mountains and do other above-ground feats. James Tabor, in his new book "Blind Descent: The Quest to Discover the Deepest Place on Earth," attempts to give some exposure to the cave divers who explore these largely unknown caves.

Tabor spoke to Jon Stewart last night about the book and why it is that people don't talk much about cave exploration. Stewart suggested that the bottom of a 7,000 foot cave "lacks the drama of a peak," even though the descent is "like climbing Mt. Everest in reverse, literally," as Tabor said. He also explained the dangers of cave diving, the most horrifying of which is psychological. "The Rapture," he said, is "like a panic attack on meth" -- "when your psyche reaches its limit of depth and darkness."

Despite the danger, Tabor said that he was looking forward to descending all the way into one of the 7,000 foot caves sometime soon.
