A team of researchers have said that there might still be an undiscovered tombwithin the Great Pyramid of Giza in Egypt.

The researchers used advanced scanning techniques in order to study the Pyramids this week and found thermal anomalies within the Great Pyramid of Giza. The multinational research team said that it found significant differences in temperaturebetween the stones at ground level on the eastern side of the Great Pyramid.The team found that some stones on the Great Pyramid were six degrees warmer or cooler than the stones next to them while the differences usually ranged from 0.1 to 0.5 degrees.

Mamdouh el-Damaty, the Egyptian minister of antiquities, said in a press release that, “The first row of the pyramid’s stones are all uniform, then we come here and find that there’s a difference in the formation. The team found that there is something like a small passage in the ground that you can see, leading up to the pyramids ground, reaching an area with a different temperature. What will be behind it?”

The team was also able to find thermal anomalies on three other pyramids in Giza and Dahshur, which is located 12miles south. However, the ministry pointed out that the temperature differences recorded at the Great Pyramid were more significant.
