Braidwood is a city in Will County, Illinois, United States, approximately 53 miles (85 km) southwest of Chicago and 18 miles (29 km) south of Joliet. The population was 5,203 at the 2000 census. The Braidwood Nuclear Generating Station, a nuclear power plant currently owned by Exelon Corporation, is also located in the area (although the plant's address is actually in the nearby town of Braceville).
The Son Doong Cave in Vietnam is the biggest cave in the world. It's over 5.5 miles long, has a jungle and river, and could fit a 40-story skyscraper within its walls. But nobody knew any of that until about six years ago.
Those in search of the deepest known cave on the planet are always lead to Georgiaâs breakaway region of Abkhazia. Deep in the mountains of the Arabika massif, this record-breaking cave can be found â it is the Krubera Cave (also known as Voronya Cave, just to keep it interesting).
