PYRA­MID PUZ­ZLE

First News - - World News -

THE mys­te­ri­ous pyra­mids of Egypt have just got a bit more mys­te­ri­ous, after sci­en­tists dis­cov­ered a large empty space deep in­side the Great Pyra­mid of Giza, the old­est of the seven won­ders of the an­cient world.

The cu­ri­ous cav­ity is thought to be 30m long and sev­eral me­tres in height. A team of Ja­panese and French sci­en­tists found the void after two years of study­ing the pyra­mid. They used a tech­nique called muog­ra­phy, which can de­tect changes of den­sity in­side large rock struc­tures. It is the first ma­jor struc­ture found in the pyra­mid since the 19th cen­tury.

The Great Pyra­mid has fas­ci­nated peo­ple for cen­turies. To this day, no­body is cer­tain how the 146-me­tre struc­ture was built. Con­struc­tion took place dur­ing the reign of Pharaoh Khufu be­tween 2509 and 2483 BC. It is known to con­tain three large cham­bers and a se­ries of pas­sage­ways, in­clud­ing a 47m-long, 8m-high one known as the Grand Gallery.

Sci­en­tists are now de­bat­ing what the pur­pose of the space might be. Some think it may be there to act as a kind of sup­port for the pyra­mid, pre­vent­ing the heavy stones from col­laps­ing.

Fur­ther tests, in­volv­ing ro­bots, will hope­fully re­veal more.
