What If the Earth Were Hollow?

By Eric Limer on at

The idea of jumping into a tunnel that travels through the centre of the Earth, and emerging on the other side to step right out is definitely fun to imagine, but what if the Earth actually was hollow? How would that affect your everyday life?

MinutePhysics, with some help from some help from Vsauce, has been thinking about just that, and has considered all the details for you. As you might imagine, the whole thing gets a bit messy. Also curious about how much water it would take to put out the Sun? Just watch, and you might get a chance to learn that too. [YouTube]
