Hollow Earth#Concave hollow Earths

The idea of ​​the inner world of the cosmos which is also called the inner world theory, interior view of the world or hollow world theory ( ambiguous, see theory of the hollow earth). This idea is that we live on the inside of a hollow earth with a diameter of 12,740 km. The theory convinced, even as they arose in the 19th century, not scientists.

The planets, the sun and the stars are located according to this theory inside this ball. The moon revolves as the next celestial body about 3000 km high above the earth's surface with the largest orbit around the inner world axis of the fixed Erdschale, then the sun comes up in about 4500 km above the earth's surface.

This worldview was first developed in 1870 by an American, Cyrus Reed Teed ( 1839-1908 ). In Germany joined the first Karl Neupert 1901 for this idea. In the thirties, the Hollow Earth theory was, inter alia, by John Lang presented as a "new world view " of the public. In 1963, the Austrian Johann Dolanski tried to make this interpretation of the cosmos on a scientific foundation. The Hollow Earth theory is based on the following assumptions:

• The earth is a hollow sphere, on the inner surface we live.
• Electromagnetic field lines and thus light do not propagate in straight lines but curved.
• The vacuum speed of light is not constant 300,000 km / s

Description

The inner world theory is based on the following axioms:

It is then purely mathematically to an inversion with respect to the earth's surface. The formulas for the calculation of planetary orbits are doing, however, complicated and not very clear. Comparable to the geocentric worldview of the Earth comes to a prominent position in the universe, not only as the center, but as a border. The inner world of theory and the geocentric world view so renounce in favor of a particular position of the earth, and thus the people, to a simple mathematical representation of physical relationships.

Comparison with all modern conveniences worldview

Mathematically is the theory with no classical physical theory in contradiction, since each coordinate system can be converted accordingly. However, losing by the inner world of theory some of the principles ( symmetries ) from which the theory was derived to be valid. So the theory is contrary to the Noether theorem, so that the fundamental conservation laws of physics would no longer apply, or even the adoption of Galileo and Newton, that the laws of physics are the same in all points of space. In general relativity, however, it is generally not possible to specify a coordinate system that spans the universe, so that a reformulation in terms of the Hollow Earth theory is impossible. To explain relativistic effects, the above axioms are therefore not sufficient, and it would further rules are introduced to support the Hollow Earth theory.

Geometric lets acceptance of the Hollow Earth theory arise the new question, what was the outside of the sphere in which we find ourselves. From the axioms and the scientific exploration of the " Earth's interior " However, it follows that there extends the earth to infinity. If you were a straight hole outwards from the center of the world continued pointing drill, the tunnel would always continue expanding until it turning inside out at infinity on the other side of the world and there again approaches the center of the world, until he breaks through the earth's surface. Only an infinitely thin beam, which has continued exactly from the center of the world would disappear into infinity. This could send an object through the tunnel, which then almost completely arrives in finite time on the opposite side of the Earth, which also corresponds to the usual theory of the world. With mathematically similar methods can, however, in any spherical object, in every stone and even in every atom core an infinitely large universe postulate.
