Why did the world get smaller in the 20th century?

The world perceived as "smaller" in the 20th century can be attributed to advancements in technology, transportation, and communication. Innovations such as the airplane and the automobile drastically reduced travel time, making distant places more accessible. Additionally, the rise of the internet and telecommunications facilitated instantaneous communication, fostering global connections and interactions. These developments led to increased cultural exchange and economic interdependence, effectively shrinking the perceived distance between nations and peoples.
