Part 1: Atom's reality
Human beings may be the first to develop thoughts into actions. But that doesnt mean they are of highest intelligence; we use a limited volume of our integrated brain. It is considered that micro-organisms have much simpler nervous systems. And it is thus assumed, they use it to its full advantage. Their metabolisms are fast. Lifetimes are short. They may be able to sense the fundamental units or building blocks of space, time and gravity. A quark or an atom may be grain of sand in their geometry. In fempto seconds they may call it a day. The gravitational waves may ripple across the wonders of their world. I have a thought that it is a continuum barrier we try to dissect.
Part 2: Nebula's reality
What about the galaxy organism or the nebula organism? What if they constitute a fundamental unit equivalent to a biological cell? Their events take aeons to complete. Their space stretched beyond lightyears. They blink at a speed of what we calculate to be the age of the universe. I have a thought that it is a continuum barrier we try to escape.
Part 3: The multiversal lattice
Are we the nodes or the basis of a multiversal lattice? What are the coordinates of our space, time and gravity on a Gigalogarithmic scale? Are we bound to our characteristic dimensional wells separated by a continuum energy barrier? Can we have the energy to hop over or tunnel through these barriers? Is it just that we can't imagine a force that hold each of these realities at some coordination?
NB: The author has degrees of imagination constrained to the dimensions of space, time and gravity
