There’s more to explore in the Great Pyramid at Giza, but scientists may need some help from robots to do it.

Researchers have used muon detectors and thermal imaging to discover two previously unknown voids in the Great Pyramid. The larger void is around 98 feet long, while the smaller one is a corridor of uncertain length. Experts are conflicted on whether the spaces were purposely designed to hold anything or not.

Because scientists can’t just take apart the pyramid, they’re working on tiny robots that can enter the smaller void and see what’s there. Glenn and Stu talked about this unique story on today’s show.

"First, we want to send a 'scout robot,' which is basically a pan-tilt camera with a lot of lights fitted in a tube-like robot," researcher Jean-Baptiste Mouret told Live Science. "The goal is to survey what is on the other side of the wall and get high-resolution pictures."
