In geography, the antipodes of any place on Earth is its antipodal point; that is, the region on the Earth’s surface which is diametrically opposite to it. Two points which are antipodal to one another are connected by a straight line through the centre of the Earth.

A nifty little site that uses Google Maps to allow you to “stick a pin” in a map to pinpoint your location, and then automatically shows you your antipodes—that is, the point on the far side of the Earth that is directly opposite from you. For example, the antipodes for Cumberland, MD (where I live) is a few thousand miles off the southwestern coast of Australia in the Indian Ocean. LINK→
