Measure before inference
Separate what a sensor or experiment directly records from values inferred through geometry, models, or interpretation.
HSARPA catalogs hypothetical technologies, anomalous observations, and research ideas that are unproven, contested, or beyond current engineering reach—then asks what the evidence actually supports.
Browse broadly, compare explanations, or audit the evidence chain.
The current research program spans reactionless propulsion, time displacement, wormholes, vacuum energy, metamaterials, gravity control, anomalous cognition, faster-than-light communication, technosignatures, exotic biology, simulation theory, and UAP evidence.
Each public dossier separates established baseline science from inference, disputed claims, measurement artifacts, missing evidence, and the experiment that would actually change the assessment.
Research on reactionless propulsion, inertial modification, momentum exchange, and propulsion concepts that test the boundary between accepted mechanics and speculative engineering.
ACCESS DIVISION → TEMPTime dilation, closed timelike curves, retrocausality, chronology protection, and the difference between verified relativistic effects and hypothetical time machines.
ACCESS DIVISION → DIMWormholes, extra dimensions, spacetime topology, exotic stress-energy, and the gap between mathematical geometries and physically traversable systems.
ACCESS DIVISION → ENERQuantum vacuum phenomena, zero-point energy, negative-energy states, and extraordinary power claims evaluated against thermodynamics and quantum field theory.
ACCESS DIVISION → MATMetamaterials, programmable matter, transformation optics, synthetic lattices, and engineered properties that separate demonstrated materials science from science-fiction extrapolation.
ACCESS DIVISION → FIELDGravity control, artificial gravity, frame dragging, gravitomagnetism, shielding claims, and precision tests of proposed field-manipulation effects.
ACCESS DIVISION → INFOFaster-than-light signaling, quantum nonlocality, no-signaling constraints, tunneling, tachyons, and proposals for information transfer outside ordinary causal channels.
ACCESS DIVISION → COGTelepathy, remote viewing, presentiment, perception, statistical artifacts, neuroscience, and the experimental standards required to test anomalous cognition.
ACCESS DIVISION → XENOTechnosignatures, artifact SETI, engineered astronomical signals, nonhuman technology hypotheses, false positives, and scientific verification protocols.
ACCESS DIVISION → BIOShadow biospheres, xenobiology, non-DNA information systems, alternative solvents, agnostic biosignatures, and evidence standards for unfamiliar life.
ACCESS DIVISION → REALSimulation-hypothesis testability, digital physics, information limits, spacetime discreteness, and claims of substrate or probability manipulation.
ACCESS DIVISION → ANOMUAP and other unresolved observations analyzed through sensor physics, geometry, chain of custody, human perception, and explicit measurement requirements.
ACCESS DIVISION →Every flagship file exposes the gap between what was actually measured and what the extraordinary interpretation would require.
Each flagship dossier carries a compact provenance trail, while the Claim Ledger maps 36 high-visibility statements to the exact anchor that supports or constrains them.
Separate what a sensor or experiment directly records from values inferred through geometry, models, or interpretation.
Thermal drift, parallax, ion wind, postselection, contamination, hidden energy and instrument behavior are part of the hypothesis space.
A claim that cannot specify what observation would count against it belongs to philosophy or fiction, not an empirical technology file.
Strong evidence survives blinded protocols, null tests, chain-of-custody controls and laboratories that do not share the original apparatus or incentives.
