What Are the Mysterious Markings Found In the Great Pyramid's Hidden Chamber of Secrets?

A robot has taken photos of a hidden secret chamber inside the Great Pyramid of Giza, which was supposedly built by the fourth dynasty Egyptian pharaoh Khufu. It's been the first time anyone accessed the secret chamber in 4500 years.

The archeologists have reached a second blocking stone, finding mysterious markings on the floor. They don't know what they are yet.

The chamber is located at the end of a 63-meter-long tight passage way going up from the Queen's chamber, which is at the center of the bottom of the gigantic 146-meter-tall pyramid, made out of 2.3 million blocks of limestone and granite.

Located south of the top of the King's chamber, the secret chamber shows mysterious markings, as well as metal pins embedded in the first blocking stone. Apparently, there's a second blocking stone behind that one. No other artifacts have been found yet, and archeologists still don't know what the red stone markings mean. They certainly don't look like your usual hieroglyphics to me.

What really worries me is this whole hi-tech archeology business. Robot archeologists, space archeologists... what are the mummies going to do? Who the hell are they supposed to curse now? They must be getting very confused at this stage of the proceedings. [New Scientist]
