The Moon's surface is made up of long-dead volcanoes and impact craters from asteroids, but have you ever wondered what might be inside it? We could find out one day by digging a tunnel through the Moon. How long would this take? What mysteries would we find inside? And how would gravity affect our dig? This is ‘what if’ and here's what would happen, if we dug a tunnel through the Moon.
Unlike the Earth's layers, we don't know much about what's inside our Moon, but we do know to get through it you'd need to dig over 3,000 kilometers. And with today's technology, doing something like this would take about 1,300 years. But what if we managed to fast forward this with more advanced technology? What would happen then?

To start our journey through the Moon we'd first want to choose an area that would give us a head start. The best choice here would be the South Pole ‘Aitken Basin’- this is a massive basin that's 8 kilometres deep. For comparison, the deepest hole on Earth is 12.2 kilometres, so this would save us a lot of time.
If we’d start digging, the first layer you'd need to worry about would be the Moon's regolith, also known as the Moon's outer crust. It may not seem like it at first, but this layer is surprisingly dangerous. Regolith is billions of years of crushed asteroids and moondust. It's razor sharp and very fine and can easily get into your suit and your drill, which will wear them down over time. And make sure you don't accidentally impale any of this stuff, as it can cause lung cancer.
You'll be digging through the regolith layer for up to 15 metres, until you reach the lunar crust. This layer is made up of bedrock and, it's where you might make some money, since rocks in the crust contain lots of titanium and aluminum. You'll also be able to find iron, calcium and magnesium. We could either bring these back to Earth or use them to help us colonize the Moon. This layer is about 100 kilometers deep.
Once you're through it, you'll then have to deal with the lithosphere. This layer used to be magma that would supply the Moon's volcanoes, but thankfully it's cooled and is now solid. What would be less thankful for, is that this layer is nearly 1,000 kilometers deep, so you'd keep drilling, and drilling... Until you've finally reached the asthenosphere.
What's different here, is that this layer is made up of molten lava. At this point your journey would definitely be over as you'll be facing temperatures of up to 1500 degrees. But we'll give you a special suit to help you survive this. On a special drill too. Now you wouldn't be drilling at this point, instead you'd be trying to swim your way through this magma. And as you get passed this, you'll be met with another liquid.
But this time it will be liquid iron, which is the outer layer of the Moon's core. Its radius is roughly 330 kilometers, so let's hope your suit can still withstand the immense heat. And as you drill your way through these thousands of kilometres, you'll notice that the gravity has been changing. As you reach the center of the Moon, the gravity will reach zero and you'll be completely weightless, floating in the Moon's inner core made of solid iron. So now that you've reached the center, it's time to make your way back out.
Through the outer core out through the asthenosphere, then the lithosphere, inner crust and, finally, the regolith layer. And drilling through wouldn't take as long as it did the first time. That's because the inner crust is about 40 kilometers thinner on this side of the Moon, which is the site that faces the Earth. Digging through the Moon has some benefits, but, overall, it wouldn't be worth it. After all, this project would take thirteen hundred years and who wants to wait that long? Maybe, building a time machine would help? But we'll leave that story for another ‘what-if’.
