Looking at something let's say a chair how much of it is stuff matter visible and how much of it is non-stuff non-matter invisible or in anything what's the ratio of stuff to non-stuff?

Answer 1

typical matter is 1000/1 to 10,000/1 empty space to solid matter.

Answer 2

The chair is primarily composed of visible matter, such as wood or metal. The invisible components would include the space between atoms and any energy associated with the chair, like electromagnetic fields. The ratio of stuff (visible matter) to non-stuff (invisible components) in the chair would be predominantly skewed towards the visible matter, with only a small fraction being the invisible components.
