Space / Time / Perception
Einstein said that physical objects are not in space, but these objects are spatially extended. In other words, space does not exist, but only the perception of space. This observation by Einstein is quite profound as it extends way beyond objects in space because it can be applied to what artists call perspective. If you look at a painting that has perspective you will swear up and down and sideways that you are looking into space because the space that your mind sees has been spatially extended but doesn’t physically exist. In other words, you can’t walk into that painting. Spatial extensions are also done with light and shadow. In general, perspective in painting is built by using triangles or combinations of triangles (squares / rectangles ) and light and shadow. In a more abstract sense, perspective is how you view the world. Here your perspective is generally based on life experiences / culture / beliefs. Your mind, after considering what you see, draws ( spatial ) conclusions. Once again space doesn’t exist.
