Shafts of this nature have not been discovered in any other pyramids as of yet. Initially they were presumed to be ventilation shafts, but doubt has been cast on this theory due to the shafts not leading all the way to the outside. This same fact also casts doubt on the theory that the shafts were used to observe certain stars. In 2010, researchers from Leeds University developed a robot that traversed the shaft and used an endoscopic camera to look through the hole previously drilled through the stone blocking the path to the outside, which revealed a small chamber with red ochre markings on the floor and followed by another large stone blocking the path.

A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave intensities decrease according to the inverse square law as they expand into three dimensional space.
