The Antigea Guide

Everything about antipodes — the geometry, the geography, the history, and the strange places on the exact opposite side of the world.

What is an antipode? The exact opposite point on Earth, explainedThe antipode is the point diametrically opposite you on the globe — the furthest place you can possibly go. Here is how it works, how to calculate yours, and why the answer is almost always wet. If you dug straight down, would you really reach China?The old playground claim, checked against actual geometry: where a straight-down tunnel from America, Europe and elsewhere really comes out — and who would actually surface in China. The rare cities that are true antipodes of each otherFewer than one in six patches of land have land on the opposite side of the Earth. These are the city pairs that actually line up — Madrid and New Zealand, Hong Kong and Argentina, Singapore and the Amazon. Why almost every antipode lands in the oceanLess than 15% of Earth’s land has land on its opposite side. That is not bad luck — it is a consequence of how the continents are arranged. A tour of the antipodal map. Point Nemo: the loneliest place on Earth, and its spacecraft graveyardThe oceanic pole of inaccessibility sits 2,688 km from the nearest land — so remote that space agencies use the waters around it to crash retired spacecraft. It is also where Moscow’s antipode falls. The longest flights on Earth vs the antipodal limitNo two airports can be more than ~20,015 km apart — the antipodal maximum. How close does modern aviation actually get, and why is the last stretch so hard? A 2,000-year history of the Antipodes: from Greek geometry to a New Zealand island groupThe idea of people walking “feet-to-feet” on the far side of the world delighted Greek geographers, scandalised medieval theologians, and ended up naming Australia, New Zealand — and one very remote island group. How Antigea finds the opposite side of the worldThe methodology behind the map: exact antipode math, open geocoding data, an expanding Street View search, and honest answers when the far side of the world is empty ocean.
