Earth’s continents are currently keeping a safe distance from one another, but what if they did slam together again, Pangaea-style?

Approximately 270 million years ago, Earth would have been a step counter’s paradise. People who now plan their days around routes that best pad the walking stats on their exercise app of choice would’ve had the opportunity to hike across one massive continent that made up all of our planet’s landmass. The puzzle pieces that are the continents we know today were at that point fused together at the end of the Paleozoic Era, and as of the early 1900s that pole-to-pole hunk of rock has been known as Pangaea – Greek for “all of Earth.” What if we stepped up the pace of the planet’s current tectonic plate travel time and pulled the continents back together? What could we expect to see happen if another supercontinent formed?

We can all thank German meteorologist Alfred Wegener for the original theory behind Earth being made up of one single landmass at some point during the planet’s history. Published in 1912, Wegener’s The Origin of Continents and Oceans showcased his hypothesis that continental drift and plate tectonics were very real and very responsible for the formation of Pangaea.
