Einstein's theory of general relativity upended humanity's understanding of the universe more than a century ago, and since then, scientists have discovered that the steady march of time is anything but steady. Among the haunting implications of general relativity is that time passes more quickly at the top of every staircase in the world than it does at the bottom.

This mind-bending phenomenon happens because the closer an object is to Earth, the stronger the impacts of gravity are. And because general relativity describes gravity as the warping of space and time, time itself travels more slowly at higher altitudes and greater distances from Earth, where gravity has less of an effect.

The 11,000-year-old carved relief, found in Turkey, is the oldest narrative carving on record. An 11,000-year-old rock-cut relief in southeastern Turkey featuring menacing animals and two men, one of whom is holding his genitalia, is the oldest narrative scene on record, a new study suggests. Archaeologists discovered the curious carvings on built-in benches within a Neolithic (or New Stone Age) building in the Urfa region. Measuring roughly 2.5 to 3 feet (0.7 to 0.9 meter) tall and 12 feet (3.7 m) long, the newly discovered rock-cut relief showcases two leopards, a bull and the two men — one grasping his phallus and the other holding a rattle or snake.
