If you've ever encountered a sinkhole, dug a hole, or even just picked up an old Jules Verne novel, you've probably wondered idly what it might be like to travel to the earth's core. This interactive visualization lets you get a sense of the scale, without ever having to pick up a shovel.

The BBC put together a visualization that lets you travel from the Earth's surface all the way down to its core along with two, side-by-side rovers, the first one digging down through dirt and rock, while the other dives through water.

Along the way, they stop at various landmarks, and show you what kinds of life you might meet as you travel. Some of these are fictional (it shows you where, outside of Star Wars, you might expect to find a Sarlacc and where Jules Verne's Nautilus could be found). But mostly it deals in creatures that are quite real, showing you how deep you would have to swim to meet up with a giant pacific octopus (quite far), or where you might see a meter long earthworm (not nearly far enough).

There are also familiar landmarks along the way: famous shipwrecks, mines, the Paris catacombs, London's underground urban farm, nuclear testing sites, oil wells, and such. But soon, the signs of life have disappeared, and the trip to the core becomes much more empty and mysterious.

You can check out the whole thing over at the BBC.
