Among the legends of ancient Rome is that of a sibyl who lived in a cave that was the portal to the underworld. In 1958, a cave was discovered on the north shore of the Bay of Naples among the ruins of Baiæ that may have given rise to this legend. It opens to a passageway that is heated by an active volcano. Robert Paget and Keith Jones spent years removing rubble, exploring the cave's layout, mapping, and speculating on its purpose.
But only when the men went deeper into the hillside did the greatest mystery of the tunnels revealed itself. There, hidden at the bottom of a much steeper passage, and behind a second S-bend that prevented anyone approaching from seeing it until the final moment, ran an underground stream. A small “landing stage” projected out into the sulfurous waters, which ran from left to right across the tunnel and disappeared into the darkness. And the river itself was hot to the touch–in places it approached boiling point.
Conditions at this low point in the tunnel complex certainly were stygian. The temperature had risen to 120 degrees Fahrenheit; the air stank of sulfur. It was a relief to force a way across the stream and up a steep ascending passage on the other side, which eventually opened into an antechamber, oriented this time to the helical sunset, that Paget dubbed the “hidden sanctuary.” From there, more hidden staircases ascended to the surface to emerge behind the ruins of water tanks that had fed the spas at the ancient temple complex.
Could anyone be blamed for believing this underground complex to be the gates of hell? Read more about it at Past Imperfect. Link -via Metafilter

1. The Moon is freakin' huge, we're talking ginormous. A natural satellite of the earth should be something closer to 30 miles in diameter, Luna is over 2000 (that's bigger than Pluto).
2. The moon doesn't have a magnetic field, but it's rocks are magnetized.
3. Some moon rocks date back 4.5 billion years and there's even one that was dated 5.3 billion years old (that's a billion years older than the Earth.
4. Moon rocks have also been found to contain processed metals like brass and mica, and uranium236 and neptunium237 (those have never been found to occur naturally).
5. The Moon also appears to be freakin' hollow!
