A gunman opened fire on a pyramid in the famed Mexican archaeological site of Teotihuacán, fatally wounding a Canadian tourist and wounding at least six others.

A Canadian tourist was killed and six others injured after a crazed gunman who opened fire atop a pyramid at the Teotihuacan ruins in Mexico Monday afternoon.

A new computational study suggests the Great Pyramid of Giza was built using a sophisticated "Integrated Edge-Ramp" (IER) system, potentially solving a 4,500-year-old architectural enigma. This model challenges traditional theories of massive external ramps or complex internal spirals,

A new Great Pyramid theory suggests ancient Egyptians used integrated edge ramps built into the structure itself.

A computer scientist believes he has discovered how Egypt’s Great Pyramid of Giza was built. Vicente Luis Rosell Roig writes in his study (“A computational framework for evaluating an

For centuries, the construction of Egypt's pyramids has been a huge source of fascination. Historical and archaeological consensus suggests the pyramids were built between 2589 and 2504 BCE, and were used as a resting place for the Pharaohs of the Old and Middle Kingdoms.

Aliens might not have built the pyramids — but the ancient Egyptians might’ve had a pretty cool hack nonetheless. A cutting-edge 3D model suggests that the Great Pyramid of Giza was constructed using a special concealed ramp that might’ve allowed them to build it in less than two decades, per a groundbreaking study in Nature.

A large void sealed inside the Great Pyramid of Giza for roughly 4,500 years has been confirmed by three independent teams of physicists using three separate detection technologies, according to a study published in Nature.
