Definitions And Axioms

This page collects the formal definitions, principles, and core mathematical objects from the original Pulse Model formalization.

1. Core hypothesis

1.1 Informal statement

The Pulse Model begins with this operational statement:

Time is not a universal background flow. Time is the accumulated local count of physical phase/pulse evolution along a worldline.

The most concrete pulse is an atomic transition. A clock based on an atomic transition counts cycles of a frequency

$$f_0 = \frac{\Delta E}{h}$$

where $\Delta E$ is the energy difference between two quantum states.

If the atom follows a worldline $\gamma$, the number of local transition cycles accumulated along that worldline is

$$N[\gamma] = \int_\gamma f_0\,d\tau$$

where $d\tau$ is proper time.

This is the basic pulse-count equation.

1.2 Deeper phase statement

A readable clock pulse is only one kind of quantum phase. More generally, a quantum path has phase

$$\Theta[\gamma] = \frac{S[\gamma]}{\hbar}$$

For a free massive object,

$$S[\gamma] = -mc^2 \int_\gamma d\tau$$

so

$$\Theta[\gamma] = -\omega_C \tau[\gamma]$$

where

$$\omega_C = \frac{mc^2}{\hbar}$$

is the Compton angular frequency.

This does not mean ordinary matter exposes a practical clock at the Compton frequency. It means that the action phase of massive matter is tied to proper time at a very deep level.

1.3 Working slogan

Matter is phase accumulation. Atomic clocks are readable phase beats. Gravity is the geometry that controls how phase/pulse counts compare between paths.

3. Definitions and notation

3.1 Spacetime

Let $M$ be a differentiable four-dimensional manifold with metric $g_{\mu\nu}$. Use signature

$$(-,+,+,+)$$

Coordinates are written $x^\mu$, with $x^0 = ct$ when convenient.

3.2 Worldline

A timelike worldline is a map

$$\gamma:\lambda \mapsto x^\mu(\lambda)$$

from a parameter $\lambda$ to spacetime events.

3.3 Proper time

For a timelike worldline,

$$d\tau = \frac{1}{c} \sqrt{-g_{\mu\nu}dx^\mu dx^\nu}$$

and

$$\tau[\gamma,g] = \int_\gamma d\tau$$

3.4 Pulse

A pulse is a countable local cycle of a physical system. In the conservative model, the cleanest pulse is a quantum transition phase cycle.

For transition energy $\Delta E$,

$$\omega_0 = \frac{\Delta E}{\hbar}$$

and

$$f_0 = \frac{\omega_0}{2\pi} = \frac{\Delta E}{h}$$

3.5 Pulse count

For an ideal clock transition $i$,

$$N_i[\gamma,g] = \frac{1}{2\pi}\int_\gamma \omega_i\,d\tau = \int_\gamma f_i\,d\tau$$

For a stable clock with constant local frequency $f_i$,

$$N_i = f_i \tau$$

3.6 Quantum phase

For a path $\gamma$,

$$\Theta[\gamma] = \frac{S[\gamma]}{\hbar}$$

where $S$ is the action.

For a free massive particle,

$$S[\gamma] = -mc^2 \tau[\gamma]$$

so

$$\Theta[\gamma] = -\frac{mc^2}{\hbar}\tau[\gamma]$$

3.7 Pulse-count metric

The metric is the rule that assigns proper-time intervals to path elements. In pulse language:

The metric is the local rule that determines how many ideal pulses a path segment can accumulate.

For an ideal clock $i$,

$$dN_i = f_i d\tau$$

so

$$dN_i^2 = f_i^2 d\tau^2 = -\frac{f_i^2}{c^2}g_{\mu\nu}dx^\mu dx^\nu$$

Since $f_i$ is clock-specific, the universal object is not $dN_i$ but $d\tau$, or equivalently the metric.

3.8 Event comparison

Two clocks can meaningfully compare pulse counts only when their worldlines intersect or when they exchange signals with a known protocol.

If two clocks start at event $A$, follow worldlines $\gamma_1,\gamma_2$, and reunite at event $B$, then the pulse difference is

$$\Delta N_i = f_i\left(\tau[\gamma_1]-\tau[\gamma_2]\right)$$

This difference is physically observable and coordinate-independent.

4. Axioms and principles

P1. Local phase accumulation

Every physical system evolves by accumulating quantum phase.

For a path or history $h$,

$$\Theta[h]=\frac{S[h]}{\hbar}$$

This is standard quantum mechanics in action form.

P2. Ideal pulse counters measure proper time

For an ideal localized clock following timelike worldline $\gamma$,

$$N_i[\gamma]=\int_\gamma f_i\,d\tau$$

This is standard relativistic clock behavior.

P3. Pulse universality

All ideal pulse counters couple to the same spacetime metric:

$$dN_i/f_i = dN_j/f_j = d\tau$$

for all ideal clock types $i,j$.

This is the pulse-language form of local position invariance and metric universality.

P4. Classical paths are stationary phase paths

In the classical limit, paths whose action varies rapidly cancel by destructive interference. The observed classical path satisfies

$$\delta S = 0$$

or equivalently

$$\delta \Theta = 0$$

This is the action-phase bridge.

P5. Gravity is pulse-count geometry

Gravity is not treated as a force field acting inside time. It is the metric structure that determines pulse/phase accumulation along paths.

Conservative version:

$$g_{\mu\nu} \mathrm{determines} d\tau$$

Speculative version:

$$g_{\mu\nu} \mathrm{emerges\ from\ consistency\ constraints\ among\ quantum\ pulse\ histories}$$

P6. Stress-energy is phase-response

Because matter phase is $\Theta_{\mathrm{m}}=S_{\mathrm{m}}/\hbar$, the stress-energy tensor is the metric response of matter phase:

$$T_{\mu\nu} = -\frac{2\hbar}{\sqrt{-g}} \frac{\delta \Theta_{\mathrm{m}}}{\delta g^{\mu\nu}}$$

This is mathematically equivalent to the standard definition of stress-energy, but the interpretation is pulse-model-specific.

P7. No universal pulse

The model rejects a global cosmic tick.

There are only local pulse counters and relational comparisons.

7. Core mathematical object

The Pulse Model can be expressed using three functionals.

7.1 Proper-time functional

$$\tau[\gamma,g] = \int_\gamma \frac{1}{c} \sqrt{-g_{\mu\nu}dx^\mu dx^\nu}$$

This is GR's clock functional.

7.2 Pulse functional

For clock species $i$,

$$N_i[\gamma,g] = \int_\gamma f_i(\xi)\,d\tau$$

where $\xi$ denotes internal/environmental variables. For an ideal clock, $f_i$ is constant.

7.3 Phase functional

For matter history $h$,

$$\Theta[h,g] = \frac{1}{\hbar}S[h,g]$$

For localized free massive worldline:

$$\Theta[\gamma,g] = -\frac{mc^2}{\hbar}\tau[\gamma,g]$$

For fields:

$$\Theta[\psi,g] = \frac{1}{\hbar} \int \mathcal{L}(\psi,\nabla\psi,g) \sqrt{-g}\,d^4x$$

7.4 Total phase

$$\Theta_{\mathrm{total}}[g,\psi]=\Theta_{\mathrm{geom}}[g]+\Theta_{\mathrm{matter}}[g,\psi]$$

Classical equations:

$$\delta\Theta_{\mathrm{total}}=0$$

Quantum theory:

$$Z=\int\mathcal{D}g\,\mathcal{D}\psi\,\exp\left(i\Theta_{\mathrm{total}}[g,\psi]\right)$$

The Pulse Model's central program is to explain the origin and meaning of $\Theta_{\mathrm{geom}}$ from pulse-count consistency.
