The dimensions of the tubes have not been accurately measured according to terrestrial measurements, but as far as can be ascertained, their diameter is roughly six kilometres and their length between 60 and 100 kilometres. | The dimensions of the tubes have not been accurately measured according to terrestrial measurements, but as far as can be ascertained, their diameter is roughly six kilometres and their length between 60 and 100 kilometres. | ||

Cross section of a ''vuqu'']]The material out of which the tubes are constructed is entirely unknown, however it presumed to have a tensile strength exceding that of all substances known to humankind. Each tube contains a lithosphere, a biosphere and an atmosphere, as seen in figure 1. | ||
Although the vuqu are closed tubes, bright apparent daylight floods the interior in a day-night cycle as on Earth. From any one position, it appears as if a bright sun-like light source, which the Goqu call ''elo'', moves each day through the centre of the tube from ''la'' 'east' to ''ta'' 'west'. The illusion of a glowing orb that travels the length of the tube during the day is, however, shattered by the fact that the portions of the tube that should be closest to this apparent singular light source are not more brightly lit. Instead, the entire tube is lit more or less uniformly with the exception of the eastern end during the morning and the western end during the late afternoon. | Although the vuqu are closed tubes, bright apparent daylight floods the interior in a day-night cycle as on Earth.
