The western world has been obsessed with the mysteries of ancient Egypt for a over a century. I think the tipping point was in 1922, when Howard Carter found the hidden tomb of Tutankhamun, the boy king.

Egypt has also been a huge draw for our museums of natural history, and I am sure also inspired more than a few people to become archaeologists.

Discoveries related to ancient Egypt have been few and far between the last few decades, as the mystery has been taken away as more research and exploration was done. Many people were beginning to wonder if there were any secrets left to discover at all?

Apparently there are.

One of the questions for the ages; who built the great pyramids, how, and why did they build them? It has baffled scientists for years. Recently, scientists started probing the Great Pyramid of Giza with particle physics tools and they have made a potentially monumental discovery.

It appears that they have discovered a massive, secret chamber inside the walls of the ancient building. It is above the chamber known as the Grand Gallery, and is comparable in size, roughly 100 feet, yet somehow it has managed to remain hidden all these years.

"The romantic interpretation and what everyone wants to hear is that this is a hidden room and the king's body is inside or there's grave goods we didn't know about or we're going to learn more about history ... and none of that is responsible speculation at the moment," cautions Peter Der Manuelian, an Egyptologist at Harvard University.

It is likely going to be a long time before anyone actually finds out what is truly in the massive hidden chamber(s). In the past, archeologists would blast through walls in the great pyramids, but that often destroyed historical (or valuable) aspects of the structures. The team wants to see if they can get some tiny robots to slip into the hidden chamber to bring back more data before they start making further moves to get into the chamber.

What do you think is hidden in the newly discovered chamber?
