Yun-Woo Choi’s work may be way more than just three dimensional.
Choi on his work:
What is real? Where am I living? What do I perceive is the real? Are invisible things - like my emotions, supernatural phenomena, dreams, God, Tao - real? Do they have some space of their own? Are people really living in the same plane or dimension even though they feel differently about the same situation?
These questions are the starting point for my work.
I have researched multiple dimensions in books about theoretical physics like The Elegant Universe and The Fabric Of The Cosmos written by Brian Greene. In these books, the author says there are 14 dimensions which have theoretically been proven. If so, there could be numerous other dimensions which overlap or hide in space. For instance, when I hold out my hand, if my shoulder was in the 4th dimension, my hand could be somewhere on the opposite side of the universe in the 11th dimension through the 8th dimension’s black hole or a star. With this idea of overlapping dimensions, I have begun to think that the invisible and intangible matter physically exists in those hidden places.
