In March 1993, German engineer Rudolf Gantenbrink conducted tests of its new robot archaeologist inside the pyramid of Cheops. Upuat robot (which in Egyptian means "a guide to the world") was instructed to climb through a narrow shaft, inaccessible to humans, and in every possible way to explore them. In fact, in the Great Pyramid of such mines abound: it vents to help in the burial chamber of Pharaoh, for example, maintained a constant temperature. Rudolph ran Upuata into the shaft, extending from the so-called "Queen's Chamber" – a ritual space, in which, however, no queen ever had. No surprises were expected: the robot simply had to go on surface (cleared, by the way, the channel that, in principle, it is useful for the microclimate of the pyramid). However, soon after the introduction of the researcher in mechanical tunnel Egyptologists the world almost had a stroke: Upuat buried in the door of white limestone, with metal parts. This discovery immediately proclaimed "the discovery a decade." It was assumed that the door is the same "secret chamber" of which now go for about a century archaeological legend! For example, an American researcher John Kinnaman pieamid before his death, said that in 1926 he found in the desert, sanded passage to a "technical room" of the pyramid of Cheops, where he had seen similar to mechanisms objects. However, the authorities forbade him to publish the discovery and re-filled entry.

Relatively recently, the French geophysicists definitely found a suspicious voids inside the pyramid of Cheops. AND But in 1993 Gantenbrink robot is getting closer to a possible door into a secret chamber … And suddenly, the study was discontinued! Without explaining the reasons, the Egyptian authorities have banned further drilling. To date, the "door Gantenbrink "-the most urgent mystery of the pyramid of Cheops. With regard to what is behind it, build a variety of assumptions from the tomb of Cheops mother, which holds no treasure estimates, and ending with a hangar, in which left its construction equipment aliens. In any case, it is clear that tourists there be allowed a very, very soon. Source:
