Abstract

What ultimately constrains knowledge? This SE Press paper unifies physics, epistemology, and protocol-grade audit to map sensory, logical, quantum, and cosmological horizons—showing how foundational answers evolve under the Gradient Reality Model (GRM) and Spectral Gravitation Framework (SGF). All limits are star-scored (★–★★★★★), cross-linked to SE Press Papers SID#001–004, and registry-audited. Some boundaries flex with advances; others are fundamental. No map can erase the spectral horizon: every answer is upgradable and audit-ready.

1. Why Ask “What Limits Knowledge of the Universe?”

Each leap in science, philosophy, or SI reveals new mysteries and exposes deeper boundaries. Are there truths forever unknowable, or do discovery and innovation just keep pushing the frontier? As established in Papers SID#001–004, knowing the reach and warrant of our knowledge boundaries shapes research, technology, SI/AI audit, and guards against overclaiming.

• See “How Do Physical Laws Arise?” (SID#003-X9JK) for emergent law constraints

• Compare cosmic horizon limits with “Why Is There Something?” (SID#002-B9QZ)

2. Main Types of Limits and Barriers (Warrant Ratings)

Sensory & Technological Limits (★★★☆☆):

Human senses see only a sliver of reality. Technology broadens reach—microscopes, telescopes—yet every device hits finite signal, energy, and context ceilings. Blue zone; mutable, but always present.

Logical & Language Limits (★★★☆☆):

Reason, logic, and language structure not just what can be known, but what can be queried or communicated. Even with new mathematics, horizons always recede. Blue zone.

Quantum/Chaos Limits (★★★★☆):

Quantum uncertainty and chaos theory enforce hard limits:

$\Delta x,\Delta p \geq \frac{\hbar}{2}$

where $\Delta x$ is position uncertainty, $\Delta p$ is momentum uncertainty, and $\hbar$ is the reduced Planck constant. Even perfect models cannot escape these red boundaries for simultaneous measurement and prediction.

Planck/Physical Horizons (★★★★☆):

The Planck scale sets a hard limit for physical meaning:

$l_P = \sqrt{\frac{\hbar,G}{c^3}} \approx 1.6 \times 10^{-35},\mathrm{m}$

where $l_P$ is the Planck length, $G$ is the gravitational constant, $c$ is the speed of light. Time, $t_P = \sqrt{\frac{\hbar,G}{c^5}} \approx 5.4 \times 10^{-44},\mathrm{s}$, sets the Planck time. The cosmic event horizon is an empirical redline: no signal can ever reach us from beyond.

Emergence, Complexity & Recursive Barriers (★★★★☆):

In complex systems (e.g., brains, weather, economy), effective laws replace fundamental ones. Predictability fades; uncertainty is structural, not just informational. These boundaries constantly move but always remain.

GRM Protocol/Spectral Horizon (★★★★☆):

GRM protocol (see SID#001-A7F2, SID#003-X9JK, SID#004-CV31) asserts: every “map” confronts a spectral horizon—no SI/AI or theory can ever exhaust all terrain. Every answer has an explicit, registry-audited limit.

Knowledge Limit Spectrum:

Sensory/Tech (★★★☆☆)→Logic/Language (★★★☆☆)→Quantum/Planck (★★★★☆)→Complexity (★★★★☆)→GRM Horizon (★★★★☆)

3. GRM & SGF Protocol Response

Spectral Horizon Law:GRM asserts: every map—physical or SI model—reaches a spectral horizon: the moving, scored edge where uncertainty outweighs confidence, and warrant must drop. Mutable limits shift with technology, but some boundaries (Planck, logical, cosmic) are protocol-hard under current law. SI must flag uncertainty when claims cross these boundaries, enforcing $C_{\text{limit}} < 1$.

Mathematical Warrant:The GRM scoring formula for mean barrier warrant:

$C = \frac{\sum_{i} q_i}{n}$

where $C$ is mean warrant, $q_i$ is confidence in overcoming each limit, and $n$ is the number of barriers scored.

For compounding (joint) uncertainty:

$C_{\text{limit}} = 1 - \prod_{i=1}^{n} (1 - q_i)$

where $q_i$ is the star warrant for each barrier. This formula accounts for the amplifying effect of multiple limits.

Example scores:

• $q_{\text{Sensory/Tech}} = 0.65$ (★★★☆☆)

• $q_{\text{Logic/Language}} = 0.72$ (★★★☆☆)

• $q_{\text{Quantum/Chaos}} = 0.81$ (★★★★☆)

• $q_{\text{Planck/Cosmic Horizon}} = 0.90$ (★★★★☆)

• $q_{\text{Complex}} = 0.85$ (★★★★☆)

• $q_{\text{GRM Horizon}} = 0.88$ (★★★★☆)

4. Limits in Action

Just as no microscope reveals atoms directly and telescopes cannot peer past the cosmic event horizon, GRM says every tool—even SI—faces a dynamic, scored boundary. The audit never ends; with each leap, the frontier recedes, but never vanishes entirely.

5. Implications

• Science: Every new advance exposes deeper limits; protocols require explicit flagging (hard vs. moving boundaries).

• AI & SI: Systems must embed horizon-detection—Planck-scale or “over-confidence” predictions trigger uncertainty protocols (see SID#004-CV31). Self-audit must update when limits press in.

• Epistemology/Philosophy: Humility isn’t optional—all answers must document spectral edge and version log.

• Policy & Funding: Invest in “horizon-probing” research (quantum gravity, black hole imaging, consciousness metrics), not just incrementalism.

• Society: Understanding knowledge’s limits builds trust, curbs overclaim, and sets realistic expectations for science, SI, and governance.

6. Provisional Answer (Warrant: ★★★★☆)

Knowledge of the universe is bounded by both mutable (senses, technology, language) and fundamental (quantum, Planck, cosmological, complexity, protocol) horizons. GRM/SGF audit ensures every answer is star-scored, versioned, and upgradable. Perfect knowledge is always over the next horizon—humility, audit, and live protocol are the only safeguards for rigorous inquiry.
