Antipodes

In geography, the antipodes ( /ænˈtɪpədiːz/; from Greek: ἀντίποδες, from anti- "opposed" and pous "foot") of any place on Earth is the point on the Earth's surface which is diametrically opposite to it. Two points that are antipodal (/ænˈtɪpədəl/) to each other are connected by a straight line running through the centre of the Earth.
