Researchers notice mysterious thermal anomalies inside Egypt's ancient pyramids

Something hidden in the walls of the Great Pyramid of Giza might be heating it up. However, the researchers are not exactly sure what it is.

The two-week long thermal scanning of the Egypt's Giza pyramids has identified mysterious thermal anomalies in its structure. According to the project experts, high temperature exist in the three specific adjacent stones at the bottom of the pyramid.

During the thermal scanning, the researchers noted that while a majority of the wall heats up and cools down each day, a particular spot on the eastern side showed significantly higher temperature than the rest of the wall. The Huffington Post reports that the temperature difference between the identified spot and the rest of the stones was nearly six degrees Celsius.

The researchers believe that something might be hidden in or behind the wall. It could be a room, a passage or some other insight.

"At the very least, this anomaly will shed additional light on the construction techniques of the 4th dynasty Egyptians," said Egyptologist Beth Ann Judas in an interview with the Huffington Post. "It's rather exciting actually. Over the past few years, archaeologists have been learning more about the workmen and officials who are connected to the pyramids, and this gives us more information about their work."

The Scan Pyramid Project was organised by Heritage Innovation Preservation Institute in Paris. The thermal anomaly was detected after the researchers conducted a scan of the pyramids at different times of the day, with a particular focus on mornings and evenings.

If the pyramid wall was constructed of the same material, all the stones would have showed uniform heating and cooling patterns during the day. However, the temperature anomaly suggests presence of different materials or cavities in or behind the wall.
