Ever stood in your backyard as a kid, shovel in hand, convinced that a few more hours of digging would land you smack in the middle of a bustling street in Beijing? Most of us did. It’s basically a rite of passage. But the reality of the opposite side of the globe—what geographers call the "Antipodes"—is actually a lot wetter and lonelier than the cartoons led us to believe.
Honestly, the math is against you.
The Earth is roughly 71% water. Since the opposite side of the globe from any given point is exactly 180 degrees of longitude and the opposite latitude away, the odds of hitting land twice are statistically slim. Most people on Earth, if they tunneled straight through the center of the planet, would just end up drowning.
The Big Myth About Digging to China
If you’re in the United States, you aren’t going to China. Sorry.
Basically, if you start digging in Times Square, you’re going to end up in the ocean off the coast of Australia. If you start in London, you’ll hit the water off the coast of New Zealand. To actually find a "land-to-land" match, you have to be in very specific spots. Think of it like a cosmic needle in a haystack.
There are only a few major inhabited areas that have a direct land-based counterpart.
Take Spain, for example. If you’re hanging out in Madrid and decide to go vertical, you’ll eventually pop out in New Zealand. Specifically near Weber. This is one of the few famous "antipodal" pairs where you can actually go from a major city to a real town on the other side.
Another weird one? Northern South America and Southeast Asia. If you're in Bogota, Colombia, your feet are pointing directly at Jakarta, Indonesia. It’s a strange thought. You’re standing on a mountain in the Andes, and directly beneath 8,000 miles of molten iron and rock, someone is navigating the humid traffic of Java.
Why Does This Matter?
It’s not just a trivia fact. Understanding the opposite side of the globe helps scientists track seismic waves. When a massive earthquake hits, say, Chile, the energy ripples through the core. Stations at the antipodal point in Central Asia pick up these "PKP" waves. These waves provide a sort of X-ray of the Earth's inner core. Without the data from the exact opposite side of the globe, we’d have almost no idea what the center of our planet actually looks like.
Finding Your Personal "Other Side"
You’ve probably seen those websites where you click a map and a little "man" tunnels through. They’re fun. But let’s look at the actual geography.
Most of North America is "opposite" to the Indian Ocean. It’s just a vast, blue expanse. If you're in the UK, your antipodal point is south of New Zealand in the Pacific. Even most of Australia—the "Land Down Under"—has its opposite in the North Atlantic.
There are some cool exceptions:
- Argentina and China: Large parts of Argentina and Chile correspond to eastern China and Mongolia.
- New Zealand and Spain/Portugal: As mentioned, this is the classic "dig a hole" success story.
- Hawaii and Botswana: This is one of the rare ones. If you leave the beaches of Waikiki and go straight down, you end up in the Kalahari Desert. Talk about a climate shock.
The Physics of the Trip
Let's get weird for a second. If you actually could build a vacuum-sealed tunnel through the Earth, the physics of the trip are mind-bending.

It would take you approximately 42 minutes to fall to the opposite side of the globe. You’d accelerate until you hit the center at about 18,000 miles per hour, then decelerate as gravity starts pulling you "back" toward the center. You’d pop out the other side with zero velocity, just in time to grab the edge and step out.
Of course, the Coriolis effect would slam you into the wall of the tunnel almost immediately, and the 10,000-degree heat of the core would vaporize you long before that. But as a thought experiment? It's pretty cool.
The Global "Ocean" Problem
If you look at an "Antipodes Map"—a map where the continents are superimposed over their opposites—you’ll notice something striking. The world is lopsided.
Most of the Earth's land is in the Northern Hemisphere. Consequently, the Southern Hemisphere is largely just the "back side" of our landmasses. The Pacific Ocean is so massive that it is actually antipodal to itself in some places. You could sail across a huge chunk of the Pacific, and your opposite side of the globe would still be in the Pacific.
This creates a "Land Hemisphere" and a "Water Hemisphere." The center of the Land Hemisphere is near Nantes, France. In this half of the world, you have about 49% of the Earth's total land. The center of the Water Hemisphere is near the Bounty Islands of New Zealand. If you stand there, almost everything on the opposite side of the globe is land, but everywhere around you is just endless blue.
Historical Obsession with the "Other Side"
Humans have been obsessed with this forever. The Greeks, specifically Crates of Mallus in the 2nd century BC, theorized that there must be people living on the other side to keep the world balanced. They called them "Antipodeans."
In the Middle Ages, this was actually a huge theological debate. Saint Augustine was famously against the idea. He argued that if there were people on the opposite side of the globe, they couldn't possibly be descended from Adam because they couldn't have crossed the vast oceans. To him, the "other side" was an impossible, empty void.
It wasn’t until the Age of Discovery that we realized the "other side" wasn't a bunch of people walking upside down with their feet growing out of their heads. It was just more ocean and a few islands.
How to Calculate It Yourself
You don't need a fancy app. It’s basic geography.
- Take your current Latitude. If it's North, make it South. If it's 40°N, your opposite is 40°S.
- Take your Longitude. Subtract it from 180.
- If you are at 70°W, your opposite is 110°E (180 - 70 = 110).
That’s it. You now have the coordinates for your personal opposite side of the globe.

Real-World Applications of Antipodes
Beyond just fun facts, the concept of the opposite side of the globe has real-world utility in radio communications.
Shortwave radio operators sometimes use "antipodal propagation." Radio waves can travel around the Earth’s ionosphere. Sometimes, signals converge at the exact opposite point from where they were sent, creating a "hot spot" of signal strength. It’s a bit of a "holy grail" for amateur radio enthusiasts—getting a clear signal from someone standing exactly on your opposite side.
Flight Paths and Travel
Technically, the "longest" possible flight you can take is between two antipodal points.
Right now, airlines are pushing the limits of "ultra-long-haul" travel. Flights like Singapore to New York are close, but they aren't quite antipodal. If a flight were to go between, say, Buenos Aires and Shanghai (true antipodes), it would be the ultimate test of human endurance and jet fuel. We’re talking 20+ hours in a pressurized tube.
Actionable Steps for Geography Nerds
If you’re fascinated by the opposite side of the globe, there are a few ways to engage with it beyond just reading.
- Use a Dual-Layer Map: Check out tools like the Antipodes Map. It uses Google Maps to show you exactly what's beneath you.
- Plan a "Symmetry Trip": If you’re a hardcore traveler, try visiting your antipodal point. If you live in Perth, Australia, your opposite is near Hamilton, Bermuda. It’s a poetic way to see the world.
- Geocaching: There are specific geocaches designed around the concept of the opposite side of the globe. Some require you to find a "partner" cache on the other side.
- Seismology Tracking: Follow real-time earthquake data via the USGS. When a major quake happens, look at the sensor data from the antipodal station. It’s a direct look at how energy moves through our planet.
The world is a lot bigger—and a lot emptier—than it feels when we’re looking at a standard flat map. The opposite side of the globe isn't some mythical land of upside-down people. Most likely, it’s just a quiet patch of salt water, with waves rolling under a sky you’ve never seen. But knowing exactly where that point is? It makes the Earth feel a little more like a neighborhood and a little less like an infinite plane.

Check your coordinates. See if you're one of the lucky few who would actually hit dry land. If not, maybe just stick to the shovel in the garden—it's safer than a 12,000-mile swim.
