The measurement of time and space on the Earth’s surface and on a satellite at 20,000 km are slightly different due to the gravitational field. Some tools of our day to-day life, such as Wi-Fi and GPS, which provides us with the best routes to our destinations on our mobile phones, would lose accuracy if they didn’t take into account the corrections imposed by general relativity.

The works by Richard Long, Ángela de la Cruz, and Julie Mehretu take different points of view to explore human movement through space and time, and its influence on urban development.
