The hypothesis of Earth expansion was first advanced by Russian scientist I. Yarkovsky nearly a hundred years ago. The idea of Earth expansion was first suggested by Alfred Wegener in the 1920's. According to him, both Americas, Eurasia, Australia and Antarctica formed Panagaea, a single land mass with no oceans between the continents. But the hypothesis of the continents have drifted apart like ships over many thousands of kilometres contradicts physics. However, the continents have still moved apart. So what is the reason for this? The first geologic grounds for this were provided by Hilgenberg. He assumed that the continents do not move along the substratum but drift from one another due to the appearance of new zones between them. This process is going on deep inside the planet and this caused the fragmentation of the single continent and the formation of the seas and oceans in the gaps between the land masses.
