You’ve probably done it. Most of us have. You’re standing in a backyard or on a beach, and you wonder: "If I started digging right now and didn't stop until I hit air, where would I actually end up?"
China. That’s the default answer for most Americans. It’s a classic bit of playground lore passed down like a sacred text. But honestly? It’s completely wrong. If you’re in the United States and you manage to dig through thousands of miles of molten iron and silicate rock, you aren't popping up in a bustling Shanghai market. You’re drowning. Specifically, you’re hitting the Indian Ocean.
The other side of the world—or what geographers call the "antipodes"—is rarely where we think it is.
The word itself comes from the Greek antipodes, meaning "feet opposite." It’s the idea of people standing on the other side of the globe with their feet pointing directly toward yours. For centuries, this wasn't just a fun geography trivia point; it was a source of genuine mapping terror. Early European cartographers like Pomponius Mela speculated about "Antichthones," people living in a southern temperate zone that was supposedly inaccessible due to the unbearable heat of the equator.

The Mathematical Reality of Your Feet
Geography is a bit of a trickster. Because the Earth is roughly 71% water, the odds of your "other side" being dry land are frustratingly slim.
Think about it this way. To find your exact opposite point, you have to flip your latitude (North becomes South) and add or subtract 180 degrees from your longitude. It’s a simple calculation, but the results are usually a bit of a letdown for aspiring world-travelers.
If you’re in New York City, your antipode is off the coast of Australia. Specifically, you’d be bobbing in the ocean southwest of Perth. If you’re in London? You’re in the South Pacific, south of New Zealand. In fact, most of Europe maps directly to the ocean. There are only a few "lucky" spots where land meets land.
- Spain and New Zealand are one of the most famous pairs. If you’re in Madrid, you’re roughly opposite Weber, New Zealand.
- Argentina and China have significant overlap.
- Parts of Indonesia map directly to the Amazon rainforest in South America.
But for the rest of us? It’s just a lot of blue.
Why We Get the Geography So Wrong
Most of our confusion comes from those flat maps we stared at in elementary school. The Mercator projection is great for navigation, but it’s a disaster for understanding true spatial relationships. It stretches the poles and makes Greenland look like it’s the size of Africa (spoiler: it’s not even close).
When we look at a flat map, our brains want to move in straight lines. We think "straight across" or "straight down." But the Earth is an oblate spheroid. The other side of the world isn't a horizontal slide; it’s a diagonal pierce through the core.
People often underestimate the sheer scale of the Pacific Ocean. It is massive. It is larger than all the Earth's landmasses combined. Because the Pacific takes up so much of the globe, its "other side" is frequently just more water—or perhaps the tip of Africa or South America.
Take the "digging to China" myth. This likely originated in the 19th century in the U.S., possibly popularized by Thoreau’s Walden or later by cartoons. But mathematically, China’s antipode is in Argentina and Chile. To actually dig to China, you’d need to be starting your journey somewhere near Buenos Aires.
The Cultural Weight of Being "Far Away"
There is something deeply psychological about the phrase other side of the world. It represents the ultimate "elsewhere."

In the 18th and 19th centuries, the antipodes represented a "topsy-turvy" land. For British convicts sent to Australia, it wasn't just a prison sentence; it was a social and physical inversion of their entire existence. The stars were different. The seasons were flipped. The animals—kangaroos and platypuses—looked like they had been assembled from leftover parts.
Even today, we use the term to describe extreme distance in our personal lives. "I’d go to the other side of the world for you." It’s the limit of human terrestrial travel. Once you pass the antipode, you’re actually starting to come back home.
Does it actually matter?
From a scientific perspective, knowing what’s on the other side helps us understand seismic waves. When an earthquake hits, p-waves and s-waves travel through the Earth’s interior. Seismographs located at the antipode of an earthquake’s epicenter provide crucial data about the density and state of the Earth's core.
So, while you can't dig there, the Earth itself is constantly "talking" from one side to the other through vibrations.
Chasing the "Antipode Map" Experience
If you want to find your specific "other side," you don't need a shovel. You just need a digital coordinate flipper. Websites like Antipodes Map or Engaging Data allow you to click a point and see the "ghost" of that location on the opposite hemisphere.
It’s a humbling exercise.
You realize that most of our "important" cities are tiny dots in a massive oceanic void. It highlights how much of our human history has been confined to a very small percentage of the planet's surface.
Practical Steps for the Curious Geographer
If you’re actually planning to visit your antipode—assuming it’s on land—there are a few things you should know. It’s not just a long flight; it’s a total sensory flip.
1. Check the Seasonality
If it’s July and you’re sweating in Madrid, it’s mid-winter in Weber, New Zealand. You aren't just changing locations; you’re jumping six months through the calendar. This affects everything from packing to jet lag recovery.
2. The 20,000 Kilometer Rule
The maximum distance between any two points on Earth is roughly 20,000 kilometers (about 12,430 miles). This is the distance to your antipode. Currently, there are very few commercial "Project Sunrise" style flights that can do this non-stop. Most people visiting the other side of the world will face at least 22 to 24 hours of travel time.
3. Use Coordinates, Not Names
When searching for your opposite, use decimal coordinates (e.g., 40.7128° N, 74.0060° W). Software treats the Earth as a grid, and it’s the only way to be precise.
4. Acknowledge the Water
Statistically, you are probably "opposite" an ocean. If you want to experience an antipodal connection, find the closest landmass to your theoretical exit point. For a New Yorker, that means a trip to the beaches of Western Australia.
The Realization
Finding the other side of the world is less about the destination and more about understanding the scale of our home. We live on a sphere that is mostly uninhabited by humans. While we feel like the world is "small" because of the internet, the physical reality of 12,000 miles of rock and iron between you and your opposite point is a reminder of how much space there still is to explore.
Stop imagining China. Start looking at the South Indian Ocean. Or better yet, look at a globe—a real, round one—and trace the line yourself. You’ll find that the world is much more lopsided, watery, and fascinating than the maps on your wall ever suggested.

To truly understand your place on Earth, identify your antipodal coordinates using a digital mapping tool. Once you have them, look up the weather, the current time, and the local terrain of those coordinates. If it's water, identify the nearest inhabited island. This simple shift in perspective moves the "other side" from a mythic concept to a physical reality, grounding your understanding of global geography in actual space rather than cultural clichés.
