- | Back to the Greek Universe is a VR model that rebuilds Ptolemy’s system of the universe on a scale of 1/1 billion. The planets are 100 times larger, the Earth rotates 100 times more slowly. The planet orbits periods are 1 million faster than they would be according to Ptolemy’s calculations. | + | Back to the Greek Universe is a VR model that rebuilds Ptolemy’s system of the universe on a scale of 1/1 billion.
