The largest cave found in the world so far. Known to the Vietnamese since 1991 as Hang Sơn Đoòng.

It's been known to the Western World as just Son Doong, since it was scientifically explored in 2009.

It was created between 2 & 5 million years ago, so if you're a creationist or live your life to a set of rules that have not changed or adapted since the Dark Ages, you should click away now.
