A simulated world
requires a host.
No confirmed simulation substrate. The central problem is evidence that could distinguish a host from the physical rules observed inside a world.
Inspect the evidence boundary
01 / The conditional argument
The simulation hypothesis and its assumptions
The simulation hypothesis depends on assumptions about consciousness, computational capacity and future civilizations. Quantum metaphors do not provide evidence or a probability estimate.
Read the analysis6 minAn internal description can be precise while its underlying cause remains unknown.
Evidence boundary / Compare the claims
Different claims.
Different burdens of proof.
Choose a claim to inspect its constraint.
Premise → conditional argument
A possible host is a premise.
An argument may assume that simulated observers can exist and that hosts would create them. Its conclusion depends on those assumptions.
ConstraintLogical consistency does not establish that a host exists.
Detecting a boundary.
Crossing a boundary.
Evidence, intervention and independence are separate claims.
02 / Interface / Mechanism required
Simulation hypothesis: proposed tests and the escape metaphor
Simulation hypotheses require testable predictions. Proposed escapes lack an established physical interface or demonstrated mechanism.

03 / Dependency / An unresolved root
Simulation interfaces and unresolved dependencies
Hypothetical host access could establish a dependency. It would not resolve ultimate reality, personal continuity or an escape mechanism.
Read the analysis6 minA rule can generate structure.
A physical theory must predict it.
04 / Emergence / From rules to predictions
Cellular automata: emergence and physical limits
A single-seed cellular automaton produces structure under fixed rules. The model does not establish a physical cosmology or a Planck-scale grid.
Read the scenario6 minA computational pattern illustrates a mechanism. Agreement with measured physics is a separate requirement.
Physical limits.
No host implied.
Optical correlations and finite signal speed constrain physical models. Neither establishes an external computer.
05 / Quantum optics / Conditional patterns
Quantum eraser: conditional interference
Selected coincidence records reveal interference while the complete detection distribution remains unchanged. The explanation separates path information from measurement order.

06 / Relativity / Causal limits
The speed of light: a limit on influence
The invariant speed imposes a finite delay on communication and causation. Apparent exceptions describe medium, geometry or measurement rather than a signal exceeding c.
Read the analysis6 minThe model still needs a measurement.
Physical studies constrain claims without identifying a simulation host.
07 / Visual analysis
Physical limits and quantum uncertainty
Physical principles, engineering constraints and quantum uncertainty impose different bounds. A minimum-uncertainty model shows what its assumptions do and do not establish.

Measurement standards, calibration and uncertainty
Shared standards and traceable calibration make measurements comparable and their limits inspectable. The Planck length is a scale, not a demonstrated ruler mark.

Black-hole density depends on mass
Schwarzschild mean density falls as black-hole mass rises. It is not a universal threshold, and cosmological models describe a different system with different assumptions.

Wi-Fi throughput: shared airtime and bottlenecks
Channel access, interference, backhaul and demand constrain Wi-Fi throughput. Device count alone is insufficient.

These institutional scenarios examine political and economic premises. They supply no evidence for a simulation host.
