Lost Pharaoh? Great Pyramid May Hide Undiscovered Tomb

Speculation swirls anew that within Egypt's Great Pyramid of Khufu there lies a hidden tomb, possibly holding the pharaoh himself, sealed there for thousands of years. The discovery of so-called thermal anomalies by a team scanning the pyramid suggests an as-yet-unidentified open space that could be evidence of a tomb. Scientists and explorers have been searching for an undiscovered tomb within the Great Pyramid since the 19th century, so far failing to find one.
