Here's what the device called an "oscillation chamber" looks like. (The dimensional lines shown on this device indicate its geometrical parameters, as explained in Img.015 (F8 - 2s) from volume 2 of my latest monograph [1/5]). This remarkable device is (1) used by second-generation UFO vehicles to generate powerful telekinetic fields that propel these starships, (2) makes them invisible to human eyes, and (3) allows them to penetrate walls without damaging those walls or the UFO. Since this advanced device has an octagonal cross-section, the columns of the telekinetic field emitted from its downward-facing outlets are also octagonal in horizontal cross-section. This is why the columns used to support the ceilings in some Christian churches, which try to mimic the pillars of such a "supernatural" telekinetic field, also receive such octagonal cross-sections in the horizontal planes. Note that the operation of the oscillatory chamber is described in volume 2 of my newest monograph [1/5] and the slightly older monograph [1/4] entitled "Advanced Magnetic Devices", the texts of which can be downloaded free of charge from the above links or from the web pages listed in "Menu 2". In turn, the characteristics of the telekinetic field which such oscillatory chambers generate, are explained in volumes 4 and 10 of the same monograph [1/4]. Because the base of the replica of the "Zhang Heng Seismograph" discussed here is shaped in an octagon, it tries to inform us in a symbolic way that it comes from space, not from Earth.
