Scans were made on the pyramids of Giza and they have found several thermal anomalies, which may be explained by voids behind the surface, according to Egypt's Ministry of Antiquities. The scientific mission is using noninvasive visualization techniques, including 3-D scans with lasers and drones to see inside the pyramids. The infrared team detected a huge anomaly on the eastern side of the Khufu pyramid, which is over 4,500 years old.

I think that this is important because it could reveal the secrets of the pyramids. For thousands of years these pyramids have been here, and now we are just discovering that there is something a little different about them, I think that this is very important. We are using different types of technology to find out these secrets as well. I think that this will help us figure out what the pyramids are hiding.
