In the popular imagination lost cities are real, prosperous, well-populated areas of human habitation that have fallen into terminal decline and been lost to history.
 Most real lost cities are of ancient origins, and have been studied extensively by archaeologists.
 Abandoned urban sites of relatively recent origin are generally referred to as ghost towns.
Lost Cities is a 60-card card game, designed in 1999 by game designer Reiner Knizia and published by several publishers.
 The objective of the game is to mount profitable expeditions to one or more of the five lost cities (the Himalayas, the Brazilian Rain Forest, the Desert Sands, the Ancient Volcanos and Neptune's Realm).
 The game was originally intended as a 2-player game, but rule variants have been contributed by fans to allow 1 or 2 further players, causing Reiner Knizia himself to later provide semi-official 4-player rules.
A lost city is a settlement that fell into terminal decline and became extensively or completely uninhabited, with the consequence that the site's former significance was no longer known to the wider world.
 The locations of many lost cities have been forgotten, but some have been rediscovered and studied extensively by scientists.
 Recently abandoned cities or cities whose location was never in question might be referred to as ruins or ghost towns.
 The search for such lost cities by European explorers and adventurers in Africa, the Americas, and Southeast Asia from the 15th century onwards eventually led to the development of archaeology.
"A Sky Full of Ghosts" is the fourth episode of the American documentary television series "".
 It premiered on March 30, 2014 on Fox and on March 31, 2014 on National Geographic Channel.
 The episode presented an in-depth treatment of black holes, beginning with John Michell's suggestion of the existence of an "invisible star" to the first discovery of a black hole, Cygnus X-1.
 The episode's title is an allusion to how light from stars and other cosmic objects takes eons to travel to Earth, giving rise to the possibility that we might be viewing objects that no longer exist.
Megalithomania is an annual conference on megalithic culture held at the Glastonbury Assembly Rooms, Glastonbury in England.
 It was named after the book by John Michell of the same name and organized by Hugh Newman, Gareth Mills and John Martineau.

 Lectures are often captured on video and distributed around the internet.
 The latest Megalithomania in South Africa has employed live streaming.
David Hatcher Childress (born June 1, 1957) is an American author, and the owner of Adventures Unlimited Press, a publishing house established in 1984 specializing in books on unusual topics such as ancient mysteries, unexplained phenomena, alternative history, and historical revisionism.
 His own works primarily concentrate on lost cities (including Atlantis and Lemuria plus pole shifts and the hollow earth as well as pre-Columbian trans-oceanic contact), suppressed technology (Nikola Tesla and free energy and UFOs and ancient astronauts and anti-gravity and vimana aircraft), and secret societies (including the Knights Templar), plus more recently time travel and cryptozoology (yeti and sasquatch).
