The opposite point
The point directly opposite Arizona on the globe, known as the antipodal point, is located in the Indian Ocean, southwest of Madagascar. This area is largely uninhabited and is situated far from any major landmasses. The closest land would be the islands of Réunion or Mauritius, but they are still quite distant from the exact antipodal point.
Halfway around the world from Boston is approximately a point in the Indian Ocean, near the island of Madagascar. This location represents the antipodal point, which is about 12,500 kilometers (7,800 miles) away from Boston. Depending on the exact coordinates used, the antipodal point could also be close to parts of the southern Indian Ocean.
An antipode is something which is opposite or diametrically opposed to something else.
antipodal
The point that is directly opposite another on the Earth's surface is called an antipode. It is therefore also the most distant possible point from the original location. Because there is relatively little land in the Southern Hemisphere, most land antipodes are in the southern oceans. Some notable sets of land antipodes are:Spain and New Zealandthe Philippines and central Brazileastern China and Argentina/ChileVietnam and southern Peruthe Malay peninsula and northwest South America(see the related links for antipode maps)
The country directly on the other side of the world from Haiti is Indonesia. This is because Haiti's antipodal point, the point directly opposite on Earth, falls within the boundaries of Indonesia.
Antipodal cells in plants provide support for the embryo sac and have a role in the development of the endosperm. They are also involved in the release of nutrients to support embryo development.
The exact opposite of California's global position would be a location that is at the antipodal point on the globe. California is located roughly between 32° to 42° N latitude and 114° to 124° W longitude. The antipodal point would be in the Indian Ocean, southwest of Madagascar, around 32° to 42° S latitude and 55° to 65° E longitude, which is remote and not near any major landmass.

Other answers mention some things about the Earth. Here, antipodal means that if 'you' have three legs on one side, 'you' will also have three legs/pods/feet on the other side.
The antipodal (opposite side of the globe) of the continental US is in the Indian Ocean and therefore is the farthest point. So much for digging to China.
An antipodal arrangement of oceans and continents refers to the opposite points on Earth's surface that are directly across from each other. For example, the Pacific Ocean is antipodal to the Indian Ocean. This concept is used in geography to study the relationships between different regions and their corresponding antipodes.
