What is the rate at which places move closer together in travel and communication time or costs?

The rate at which places move closer together in terms of travel and communication time or costs is often referred to as "time-space compression." This phenomenon is driven by advancements in transportation technology (like high-speed trains and airplanes) and communication technology (such as the internet and mobile devices), which reduce the time and cost associated with moving people and information. As these technologies improve, geographical distances become less significant, enabling faster connections and interactions between locations. Ultimately, this leads to increased globalization and interconnectivity.
