Consider the source. While
this article brings up some current field research, at the same time it misrepresents basic facts. For example, there's this statement:
The King's Chamber has two shafts connected to outside, but two tunnels from the Queen's Chamber
deep inside the widest part of the pyramid have two stone doors.
Some experts now believe this may indicate a secret chamber, further still within the pyramid.
What "experts" are these, exactly? The media loves to toss in impressive words to draw in the reader. These shafts contain no doors, of course. The shafts are only about eight inches square, so unless they were carved for Smurfs to use, no human was meant to access them in the first place. The so-called "doors" are simply limestone plugs. They don't open, nor do they function in any other manner as doors. When a plug is breached they invariably find just more shaft.
The caption to one of the photos in article opens with: "Hieroglyphics such as this are common in pyramids." Well, no, hieroglyphs are not common in pyramids. They don't appear inside pyramids until the end of Dynasty 5, some 150 years after the Great Pyramid was built. Prior to the end of Dynasty 5, almost no pyramid contained any form of interior inscriptions. The sole exception is the Step Pyramid of Djoser, where in rare instances the subterranean chambers deep below the pyramid contain a smattering of hieroglyphs.
Again, consider the source. Always be wary of media articles on ancient topics. They tend to be loaded with mistakes and assumptions.
Aus's post drew my attention to the comments people left below the article. Wow, quite the collection of uninformed fringe fanatics.
