Properties of Substance = Space + Time + Inertia + Motion + Gravity
Everything that exists — matter, energy, and thought — shares five fundamental properties. These properties are not features of empty space or abstract dimensions. They only exist because substance exists.
Think of it this way: a wave has height, speed, and shape. But without water, there is no wave. Similarly, Space, Time, Inertia, Motion, and Gravity are properties that ride on substance — they vanish if substance vanishes.
Space — The “How Big” of Substance
Space is the extent that a substance occupies. It is not a blank container waiting to be filled; it is defined by what fills it.
- A rock on a table takes up dense, compact space.
- A radio signal from a satellite spreads across thousands of kilometers of space.
- A memory of your childhood home occupies “mental space” — real, but not physical.
Imagine you’re standing in a dark room. You say, “there’s nothing here.” But the room is full of air molecules, radio waves from nearby cell towers, and your own thoughts. “Empty” just means empty of what you can see. True void — absolutely nothing — doesn’t exist in this framework.
Time — The “How Long” of Substance
Time is the duration that a substance persists. It doesn’t tick on its own; it measures how long something lasts.
- A mountain lasts millions of years — near-infinite time.
- A flash of lightning lasts a fraction of a second — very short time.
- A thought can feel like it lasts forever or vanish in an instant.
Anyone who has waited in a hospital for news of a loved one knows that mental time and clock time are completely different things. An hour can feel like a day. Your thought-substance is stretching its own duration. This is not merely poetic — it reflects that mental time operates by different rules than physical time.
Without substance, there is nothing to measure the duration of. Time collapses.
Inertia — The “Stubbornness” of Substance
Inertia is the tendency of substance to stay centered in its current state. The more compact and structured the substance, the more it resists being disturbed.
- A spinning gyroscope resists being tilted — it wants to stay oriented as it is. This is inertia as centeredness.
- A billiard ball sitting on a table has no active inertial force. The moment you push it, it pushes back — that’s inertia kicking in.
- A rigid belief system in the mind is a kind of mental inertia: it resists updating even when new evidence arrives.
Think of a stubborn old professor who has held the same view for 40 years. Every challenge to his worldview is met with resistance. His thought-substance is highly “centered” — highly inertial. On the other hand, a curious student with an open mind has low mental inertia; their thoughts are free-flowing and easily shift with new understanding.
Motion — The “Restlessness” of Substance
Motion is the intrinsic spread or movement of substance. Less centeredness (low inertia) means more motion.
- A rock barely moves on its own — high inertia, low intrinsic motion.
- Light races at 300,000 km/s — very low inertia (for a physical phenomenon), very high motion.
- A thought jumps from Paris to your childhood in milliseconds — near-instantaneous motion in mental space.
Imagine substance on a spectrum from “frozen” to “wild”:
- Matter = ice cube (mostly still, compact)
- Energy = a fire (spreading, fast)
- Thought = a spark in dry grass (instantaneous, everywhere at once)
Inertia and Motion are deeply linked: inertia preserves the existing motion of a body. Light doesn’t slow down because its small but real inertia locks in its speed. It’s not going fast despite its properties — it’s going fast because of them.
Gravity — Inertia for a Family of Bodies
If Inertia is the stubbornness of a single body, Gravity is the stubbornness of a whole system of bodies. It keeps a community of substances in their shared equilibrium.
- The solar system is not held together by gravity pulling everything inward like a magnet. Rather, gravity acts like a referee ensuring that the Sun, Earth, Mars, and all the moons keep their agreed-upon dance going.
- When a comet intrudes and disturbs the equilibrium, gravitational forces arise to restore balance.
Picture a family of musicians playing in harmony. No one is fighting for control — the music just flows. But if one musician suddenly plays off-tempo, the others instinctively adjust to restore the ensemble. Gravity is that restoring force for celestial bodies.
Why This Differs from Standard Science
| Standard Science | Postulate Mechanics | |
|---|---|---|
| Space | Empty container, exists independently | Extent of substance; can’t exist without it |
| Time | Universal clock ticking on its own | Duration of substance; vanishes without substance |
| Inertia | Resistance to change in motion | Centeredness of substance; determines intrinsic motion |
| Motion | Result of applied force | Intrinsic property linked to inertia |
| Gravity | Force of attraction between masses | Equilibrium-restoring force for a system of bodies |
The key shift: science treats space and time as the stage on which substance performs. Postulate Mechanics says there is no stage without the performer — space, time, and all the rest are costumes worn by substance itself.
This reframing has a profound implication: the universe is not an empty theater with things moving around in it. It is pure substance, and all the properties we observe — extent, duration, resistance, movement, balance — are simply substance knowing itself in different ways.
