Departure point

Defining new spaces through imagination- what people perceive mentaly and is invisible I'd like to examine physicaly. Would it change the way people understand the space? If physical object would exist, would/how it change society and what issues it would raise?
Even starting with Greenwich meridian line. The meridian line becomes departure point, and perhaps, vanishing point for coordinates geographically, and a focal point for my experiments.
How does space changes over time in relation to meridian line?
