Ask which explanation best fits the measurement—and what new observation would force the explanations apart. Each flagship dossier is represented by an ordinary interpretation, an intermediate model, and the strongest extraordinary hypothesis under consideration.
Start with the actual measurement, record, or reported effect.
Keep ordinary, intermediate, and extraordinary explanations in the same hypothesis space.
Specify the test that makes one explanation predict something the others do not.
The apparent thrust is produced by thermal expansion, electromagnetic coupling, vibration, outgassing, cable forces, ion wind, or balance behavior rather than new momentum physics.
Repeat the signal after orientation reversal, isolated power delivery, thermal dummy loads, magnetic shielding, hard vacuum, and a mechanically different balance.
The device exchanges momentum with radiation, fields, expelled matter, or another external reservoir that has not been fully measured.
Close the momentum budget by directly measuring the corresponding radiation, mass flow, field interaction, or recoil reservoir.
A closed apparatus produces repeatable net impulse through a mechanism outside established momentum accounting.
Independent laboratories reproduce a directionally reversible force while every ordinary momentum path remains quantitatively excluded.
Observed temporal displacement is ordinary special- or general-relativistic time dilation.
Predict clock differences from velocity and gravitational potential, then match them with precision timing.
A spacetime solution contains closed timelike curves, but the required geometry or stress-energy is not physically realizable.
Show a stable configuration consistent with quantum fields, finite resources, and realistic boundary conditions.
Information can be controllably delivered to an earlier event rather than merely described by a time-symmetric formalism.
Transmit unpredictable information to a pre-registered receiver before the sender chooses or generates it, with no ordinary leakage path.

A stable geometry connects distant regions with physically traversable causal paths.
Measure geometry-dependent transit or lensing signatures that uniquely distinguish a traversable structure from conventional propagation.
Observed photons, forces, or energy transfer arise because an external drive changes boundary conditions or quantum states.
Account for all drive energy and show the output remains consistent with ordinary conservation.
The claimed excess energy comes from hidden electrical, thermal, chemical, RF, calibration, or timing inputs.
Run isolated calorimetry and long-duration closed accounting with independent instrumentation and matched dummy loads.
A cyclic device delivers repeatable net work while returning all control systems and boundaries to their initial state.

Unusual properties arise from structure-dependent effective responses within known electrodynamics, acoustics, or mechanics.
Predict bandwidth, loss, geometry, and scaling from the engineered unit cell and verify those limits experimentally.
The material can change useful properties in response to control signals, but remains constrained by power, speed, fabrication, and defect rates.
Demonstrate repeated macroscopic reconfiguration with measured energy, latency, durability, and error budgets.
A material exhibits broadband, scale-independent or conservation-defying behavior beyond known effective-medium limits.
Show independent measurements across frequency, scale, angle, temperature, and load that survive causality and energy-accounting checks.
The apparent gravity effect is rotation, linear acceleration, vibration, magnetic force, electrostatics, buoyancy, or another conventional interaction.
Use differential gravimetry and inert reference masses while changing orientation and shielding known force channels.
The system measures genuine frame dragging or another general-relativistic effect at the tiny magnitude predicted by theory.
Match magnitude and geometry to general relativity across independent instruments and operating states.
The apparatus changes gravitational coupling, shielding, or local spacetime curvature beyond ordinary mass-energy effects.
Detect the same field change with multiple independent gravimeters and test masses while excluding electromagnetic and mechanical coupling.
Above-chance performance results from sensory cues, procedural leakage, judging artifacts, implicit learning, or experimenter effects.
Use adversarial blinding, automated target handling, fixed scoring, isolation, and independent replication.
The anomaly is produced by flexible analysis, optional stopping, selective reporting, or a file-drawer effect.
Pre-register endpoints and analysis, publish all trials, and reproduce the effect prospectively across laboratories.
Participants acquire target information without a known sensory or inferential channel.
Demonstrate reproducible information gain under automated double-blind conditions with a physically isolated target and fixed scoring.
Quantum systems show correlations that violate classical expectations but cannot be controlled as a communication channel.
Attempt message transmission while verifying that receiver statistics remain independent of sender choice without the classical channel.
Group velocity, tunneling, pulse reshaping, or phase effects look faster than light without carrying new controllable information superluminally.
Encode unpredictable information in the earliest causal front and compare arrival against a vacuum light-cone reference.
Controllable classical information arrives outside the sender’s light cone.
Pre-register sender and receiver clocks, transmit unpredictable bits, and replicate spacelike-signaling above chance with synchronized independent timing.
The candidate signature is generated by an unusual but natural stellar, planetary, plasma, or chemical process.
Search for population-level analogues, correlated natural observables, and physically plausible source models.
Radio interference, satellites, processing artifacts, calibration, terrestrial chemistry, or observer selection creates the apparent signature.
Repeat with independent observatories, off-target controls, geolocation, instrument swaps, and chain-of-custody checks.
The signal or artifact exhibits structure that is difficult to obtain through known natural or human processes.
Confirm independently and show multiple converging engineering indicators such as modulation, manufacturing regularity, isotopic control, or waste-heat consistency.
The unusual sample is an extremophile, contaminant, virus, prion, or poorly characterized member of known biology.
Use contamination controls, sequencing, culturing, microscopy, isotope analysis, and independent laboratories.
The unusual chemistry was engineered by humans and demonstrates alternative biochemical possibility without representing an independent genesis.
Establish provenance and compare polymers, genetic systems, and metabolic pathways with known synthetic-biology lineages.
A natural organism uses a biochemical lineage genuinely independent of known terrestrial ancestry.
Show incompatible information chemistry or chirality plus independent replication, environmental context, and exclusion of contamination or engineering.
An apparent discreteness, symmetry violation, or information bound reflects deeper physical law rather than simulation artifacts.
Fit the observation with falsifiable physical models and test additional predictions across independent phenomena.
Physics is fruitfully described in information-theoretic or discrete terms without implying an external simulator.
Show that computational structure predicts novel measurements while remaining agnostic about metaphysical substrate.
Observed artifacts uniquely require a parent computational system outside the accessible universe.
Identify a signature that excludes ordinary new physics and makes independently testable predictions about substrate constraints or intervention.
The observation is a balloon, aircraft, satellite, astronomical object, parallax effect, glare, radar ambiguity, compression artifact, or atmospheric phenomenon.
Recover range, geometry, calibration, metadata, and independent sensor context sufficient to reproduce the apparent behavior conventionally.
Electronic warfare, deception, classified technology, drones, or coordinated sensor effects produce the unresolved observation.
Correlate emissions, platform behavior, geography, and multi-sensor inconsistencies while respecting missing classified context.
A physical craft performs measured accelerations, transmedium motion, or signature control beyond known aerospace capability.
Acquire calibrated multi-sensor range and velocity data with chain of custody that directly measures extraordinary performance rather than inferring it from image motion.
