Primary research, official lectures, experimental constraints and useful foundational records. Each source has a stated purpose and a limit.
Penrose's argument that superposed mass distributions may have a finite lifetime related to gravitational self-energy differences.
Scope: A proposed modification/extension of quantum dynamics, not an experimentally established universal collapse law.
Open the original record ↗Penrose's later statement of the case for gravity changing quantum theory and limiting the lifetime of sufficiently different mass configurations.
Scope: An argument for a hypothesis; do not present it as a derivation from ordinary unitary quantum mechanics.
Open the original record ↗An official Oxford-hosted 2019 lecture and synopsis in Penrose's own framing, describing gravitational OR and the proposed Orch-OR relationship to consciousness.
Scope: The user’s original clip remains unidentified. Do not call this the talk they saw or invent a timestamp or verbatim quotation. Review media license before republishing.
Open the original record ↗A Gran Sasso radiation search that constrained a specific Diósi–Penrose implementation and ruled out its natural parameter-free version.
Scope: Does not rule out every gravity-related collapse proposal; distinguish the 2020 online publication from the 2021 issue date.
Open the original record ↗A trapped-ion protocol uses squeezing and a reversed squeezing operation to amplify a small coherent displacement.
Scope: Quadrature squeezing is not simply pushing bulk material between plates. This experiment is an example of coherent reversible control, not proof that every compression procedure is reversible.
Open the original record ↗The laboratory's accessible explanation of the Burd experiment, including redistribution of uncertainty and reversal of squeezing.
Scope: Use the associated Science paper for detailed quantitative claims. Avoid treating a balloon analogy as the actual quantum mechanism.
Open the original record ↗An atom interferometer produced interference after wavepackets followed paths separated by as much as 54 centimetres.
Scope: This is wavepacket separation rather than arbitrary physical stretching. Interpretation of the superposition claim was challenged; pair with the 2016 comment and reply.
Open the original record ↗A published critique of what the half-metre experiment's random-phase interference can establish about coherence and macroscopic superposition.
Scope: A scientific comment, not a reversal or retraction of the original experiment. Include the authors' reply for balance.
Open the original record ↗The experimenters argue their result constrains modifications that reduce interferometer contrast and defend their use of superposition.
Scope: Only the publisher's accessible opening argument was read; full subscription text was not accessed.
Open the original record ↗Rapid modulation of a circuit's effective electrical boundary generated radiation with two-mode squeezing.
Scope: An effective moving electrical boundary, not mechanically slammed metal plates. Photon energy is supplied by the modulation drive; no free-energy claim.
Open the original record ↗An optical field can carry orbital angular momentum, and an astigmatic optical system can reversibly transform specified spatial modes.
Scope: Twisted phase structure is not a wave breaking apart or undergoing quantum collapse. The torque measurement in this paper was proposed, not reported as performed.
Open the original record ↗Coherent illumination and dissipation can be tuned so an absorbing structure has no outgoing signal in selected channels.
Scope: Interference alone does not erase energy; the lossy material receives it. Perfect absorption is conditional on frequency, input state and structure.
Open the original record ↗Counterpropagating coherent beams in a silicon cavity demonstrate phase-dependent control of absorption.
Scope: The article has an erratum; consult the corrected record for detailed numbers. This is engineered optical absorption, not an objective-collapse test.
Open the original record ↗Fullerene interference contrast decreased as background-gas collisions increased, in quantitative agreement with decoherence theory.
Scope: Loss of accessible interference is not, by itself, proof of fundamental single-outcome objective reduction.
Open the original record ↗Thermal emission from heated C70 molecules reduced observed matter-wave interference.
Scope: Addresses radiation-mediated environmental decoherence; it does not establish that temperature universally destroys every kind of quantum state.
Open the original record ↗Continuous weak measurement and environmental monitoring tracked conditioned qubit states and influenced their trajectories.
Scope: Conditioned quantum-state updates and monitored dynamics do not settle the interpretation of the measurement problem.
Open the original record ↗Pulsed electromechanics produced and characterized entanglement between two mechanical drumheads.
Scope: Macroscopic refers to controlled mechanical objects; it is not evidence for arbitrary room-temperature everyday-object entanglement or collapse.
Open the original record ↗Annihilation transforms particle–antiparticle rest energy and kinetic energy into allowed outgoing particles.
Scope: Opposite electric charges are not sufficient for annihilation. An electron and proton do not form an annihilating particle–antiparticle pair; the products are not always only photons.
Open the original record ↗The NIF experiment demonstrates inertial confinement compression and nuclear fusion with target gain above one.
Scope: Target gain is not whole-facility net electricity. Fusion is a nuclear reaction, not ordinary wave superposition or proof of quantum collapse.
Open the original record ↗Boundary conditions determine guided electromagnetic modes and their cutoff frequencies.
Scope: Cutoff is mode- and geometry-dependent. Evanescent fields can remain below cutoff; do not claim the field is globally erased or that every guide has the same cutoff structure.
Open the original record ↗Rectangular waveguide geometry sets transverse wave numbers and propagating-mode thresholds.
Scope: A teaching derivation for idealized guides; realistic conductivity, dielectric filling and finite-length tunnelling need additional treatment.
Open the original record ↗Coherent acoustic waves in birefringent ferroelectrics can convert light between optical polarization modes.
Scope: Conversion is mediated by material coupling and phase/momentum conditions; it is not a universal wave-to-anything transformation.
Open the original record ↗Laboratory observations quantify altered wavelength and attenuation of surface waves in grease ice.
Scope: Ice modifies wave propagation rather than universally eliminating it. Grease ice is not interchangeable with a solid ice sheet or every freezing process.
Open the original record ↗Dimensionless relationships organize how ice inertia, viscosity and elasticity alter dispersion and attenuation.
Scope: A continuum-model comparison; an analogy to quantum freezing or objective collapse would require independent reasoning.
Open the original record ↗Time-dependent magnetic fields can drive transitions between angular-momentum states.
Scope: Resonant driving changes occupation amplitudes; it does not automatically produce a recorded outcome or fundamental collapse.
Open the original record ↗Parallel conducting boundaries suppressed available modes at a Rydberg-atom transition and lengthened the observed lifetime.
Scope: Suppressing decay at a selected transition is not stopping time, removing all vacuum fluctuations or eliminating every decay channel.
Open the original record ↗Frequent probing inhibited driven transitions between trapped-ion hyperfine states.
Scope: The original language uses measurement collapse, but the experiment is not a discriminator proving a gravity-induced or consciousness-induced objective-collapse theory. Publisher lists comment and reply.
Open the original record ↗Changing the probing frequency of trapped sodium atoms suppressed or enhanced escape dynamics.
Scope: An unstable, controlled tunnelling system; it does not imply time alone kills arbitrary waves or that all measurements inhibit decay.
Open the original record ↗Matter-wave soliton collisions show phase-dependent dynamics; departure from an integrable regime can enable dynamical collapse.
Scope: Dynamical condensate collapse is not synonymous with measurement-induced wavefunction collapse. Solitons may survive collisions; collision is not a universal destruction mechanism.
Open the original record ↗A beam-splitter two-photon interference measurement reveals temporal indistinguishability and correlation structure.
Scope: Single-photon path splitting does not mean a photon was cut into two fractional particles. Classical crest/trough drawings do not by themselves describe two-photon interference.
Open the original record ↗A driven spin-1 atomic system exhibited phase synchronization dependent on engineered dissipation.
Scope: Synchronization is not compression, and the specific quantum system differs from classical oscillators with a simple visible trajectory.
Open the original record ↗A June 2026 experiment reports synchronization between two engineered quantum limit-cycle oscillators, encoded in a joint relative-phase signal.
Scope: The authors distinguish synchronization from entanglement. The result depends on engineered dissipative dynamics, not mere contact or generic compression.
Open the original record ↗Classical damping removes organized oscillator energy, often into thermal degrees of freedom; removing a drive does not erase existing motion instantaneously.
Scope: A classical oscillator model. Its amplitude envelope is not a quantum probability amplitude or an objective-collapse law.
