Dimension: a realm that cannot be imagined but exists solely in imagination. From the perspective of physics, dimension is a way of describing space and time. Beyond the four-dimensional spacetime that humans can perceive, there exists a higher-dimensional space that is beyond experience and impossible to describe. In traversing the highly rational domain of "physics" and translating this into painting, it navigates two different levels of orientation: the macroscopic structure of the external world and the microscopic paths that shape one’s self-awareness. The "invisible existence" that only resides in the "unspeakable" is conveyed through the layering, erasure, traces, and emotional expression of paint left on the canvas, allowing the very existence of the painting to manifest. Between dimensions, it is an existence that can only be imagined in an invisible realm of imagination.
