How long would it take to travel through the Earth?

A Walk Around the World: Contemplating a Journey Through (and Around) the Earth

The idea of travelling through the Earth’s core conjures images of Jules Verne-esque adventures, fiery molten rock, and insurmountable pressure. While a journey to the Earth’s center remains firmly in the realm of science fiction, the sheer scale of our planet is readily apparent when we consider a more feasible, albeit still monumental, undertaking: circumnavigating the globe.

Forget rockets and supersonic jets. Let’s consider a journey undertaken at a much more human pace: a brisk walk. The question then becomes, how long would it take to walk around the world?

The Earth’s circumference at the equator is approximately 40,075 kilometers (24,901 miles). Assuming a brisk walking pace of, say, 5 kilometers per hour (approximately 3 miles per hour), a continuous, uninterrupted walk would require an astounding 8,015 hours.

This translates to roughly 334 days of constant walking, without rest, sleep, or any stops for sustenance. Even factoring in a more realistic pace, accounting for breaks, rest, and the inevitable need for food and sleep, the journey would easily extend into years.

Consider the logistical hurdles: obtaining visas for numerous countries, navigating diverse terrains, ranging from scorching deserts to treacherous mountain passes, and securing safe passage through various regions. The challenge goes beyond mere physical endurance; it necessitates meticulous planning, significant financial resources, and unwavering resolve.

While traversing the Earth’s core remains an impossible dream, walking around it provides a tangible way to grasp the planet’s immense size. The sheer number of hours – thousands – required for such a journey underscores the daunting scale of our world, a scale often overlooked in our increasingly interconnected, digitally-shrunk reality. The hypothetical walk serves as a powerful reminder of the planet’s vastness and the limitations of human scale in the face of such geological grandeur. It’s a journey that, while physically possible, would truly test the limits of human endurance and perseverance, transforming a simple walk into an epic testament to the planet’s awe-inspiring dimensions.
