But a fascinating map has revealed that most populated places on Earth have an opposite point somewhere in the ocean.
The interactive Antipodes Map lets you check any location on the surface of the planet to check where it's opposite point is.
The Chinese are among the relative minority of countries who would strike land if they were to undertake this enterprise, according to the website where you can try out the tool for yourself.

There are no non-stop scheduled flights between any two antipodal locations by commercial airline service.

The North and South pole are, by definition, antipodes.
Scientists have previously calculated the journey time, were tunnel diggers to make it all the way through the Earth's core and out to the other side.
Research has previously found that it would take a person 38 minutes to fall from one side of the planet to the other.
The latest time estimate was calculated by Alexander Klotz, a graduate student of physics at McGill University in Montreal, Canada and published in The American Journal of Astrophysics.
Originally it was believed that this would take it would take 42 minutes and 12 seconds to fall through.
But the hypothetical scenario, published in 2015 scenario, found that when the different densities of Earth's layers are taken into account, the trip is four minutes shorter than predicted.
