Why do we sleep? Although we know that a circadian clock puts people on a sleep/wake cycle, we don’t completely understand why. We spend roughly a third of our lives sleeping, which is when our bodies repair tissues and carry out other maintenance tasks. Why do we need to sleep when other organisms don’t? There are a few different theories, but none seem to provide a convincing response. According to some theories, others who must stay more awake can rest and recover in different ways without entirely sleeping. In contrast, others who can sleep have evolved the capacity to conceal from predators. While they still don’t fully understand why humans do it, scientists are beginning to understand its significance and how sleep affects vital processes like brain development.

It’s part of a complex including two other smaller pyramids and numerous temples that were built to honor Khufu and his family. Now, thanks to Harvard University’s 3D Explore project, we can experience this incredible pyramid like never before. 

Harvard University’s Giza Project project allows us to explore the Great Pyramid from all angles virtually with detailed imagery from a long-distance drone survey. It allows us to go inside the pyramid and explore its inner chambers as if we were actually there in person – something not many people have had the opportunity to do in history!
