I have not heard of a geon before in the context of physics, so I looked it up. As far as I can tell, a geon is only theoretical. It is generally believed that they cannot be stable particles, therefore all the research is just on the theory. I say 'in the context of physics' because geon is also a term used in a different type of science - psychology. In this context, geons are used in object recognition experiments. A geon is a simple shape or object such as a circle or cylinder that, when combined with other geons, stimulate recognition of more complex objects. For example, a sphere set on top of a cone often makes people think of an ice cream cone. The idea is that visual recognition, on the most basic level, can be broken down to the spatial relationship of simple shapes.
