Diomede Islands: Walk Between Past and Future

The Diomede Islands, located between Alaska and Siberia, offer a rare real-world illustration of 'time travel' due to their position on opposite sides of the International Date Line. Just 3.8 kilometers apart, Little Diomede (U.S.) and Big Diomede (Russia) exist in different time zones, with Big Diomede being up to 21 hours ahead, so walking across the ice in winter would allow a person to 'step into yesterday' or 'tomorrow.' While this phenomenon captivates the imagination by blurring the boundaries between past and future, crossing the border is strictly illegal. This geographic and temporal oddity highlights how human-made constructs like time zones can dramatically affect everyday reality.
