Particles of what? What does this true essence look like? Matter consist of atoms which in turn consist of sub-atomic particles which in turn consist of further sub-atomic particles. Where does this breakdown stop? What are sub-atomic particles made of? Are these particles made of different elementary substances or are they made of the same substance but having different shapes and sizes? Or are they made of still smaller particles? If so, then what are these smaller particles made of? We now have a logical loop of which the only escape is to conclude that eventually we will reach the smallest particles and the most elementary substances.
But is it possible that there be more than one elementary substance? Imagine a sphere that has no empty space within it. This sphere would completely displace empty space with, I suppose, full space. This sphere would have to be one particle or be made up of parts that fit together exactly so as to leave no empty space between the parts. Can you imagine another sphere that contains no empty space but is made of a substance other than "full-space?" I cannot. This leaves us with a universe made of two substances - empty space and full-space; or if you like, a universe of one substance (full-space) within empty-space.
What shall we call this "full-space?" My dictionary defines "stuff" as "the fundamental element or basic material of the anything". So I may refer to "full-space" as stuff or the true essence of the universe. Here is the discussion on substances stated as a postulate. |
