Excerpt from the short story "The Great Pyramid."

Several years ago in Cairo, the impossible occurred. Without warning, the Great Pyramid of Giza flipped itself upside down. I had just landed in the city when it happened. Tourists and residents didn’t know what to think. Before it happened, the monument sat comfortably on its base. Now it sits precariously on its tip. The modern buildings surrounding the pyramid now lie in the shadow of its outwardly sloping sides. In order to appease the tenants in these buildings and to dampen any fears of a massive collapse, engineers were immediately called to gauge the structural integrity of the reversed pyramid. After the engineers came the religious leaders. They all traveled to Cairo from across the world hoping to see the monument for themselves.

Scientists were as perplexed as ever. Many theorized that the sudden reversal was a sign we all live in a simulated reality. Others felt that the whole thing was an elaborate optical illusion created by the Egyptian government to garner publicity. Many theories have been put forward to explain the unusual event. Perhaps the most interesting was the theory of Dr. M. Branson of Cambridge, Massachusetts.
