In this framework, a micron-scale extra dimension suppresses Hawking evaporation, allowing PBHs with initial masses \\(M \\gtrsim 10^{10}\\,\\mathrm{g}\\) to survive to the present epoch. Moreover, the memory burden effect, a quantum-gravitational suppression of the evaporation rate by \\(S^{-p}\\), significantly prolongs PBH lifetimes and enlarges the allowed parameter space. We compute the evaporation dynamics for rotating 5D PB"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"A detection of the predicted gravitational wave background would provide simultaneous evidence for a micron-sized extra dimension, PBH dark matter, and the memory burden effect, offering a decisive test of quantum gravity and extra-dimensional physics.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The assumption of a log-normal primordial power spectrum with fixed σ=1 and f_PBH=1, together with the memory burden exponent p=2 applied to 5D rotating black holes, which directly sets the amplitude and shape of the computed GW spectrum.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"5D rotating PBHs in the Dark Dimension with memory burden produce a stochastic GW background peaking at nHz to Hz frequencies, detectable by future observatories within the mass window 10^10 to 10^21 g.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Rotating five-dimensional primordial black holes produce a stochastic gravitational wave background detectable by LISA and DECIGO that could confirm a micron-scale extra dimension, PBH dark matter, and memory burden suppression.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"c85d008f341ac7a695685aa55d6a4c353cba492407ac37776db55b42b150bc5d"},"source":{"id":"2605.12948","kind":"arxiv","version":1},"verdict":{"id":"41c5a92d-54c6-465f-b82c-4ba71824fd82","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-14T18:59:11.176000Z","strongest_claim":"A detection of the predicted gravitational wave background would provide simultaneous evidence for a micron-sized extra dimension, PBH dark matter, and the memory burden effect, offering a decisive test of quantum gravity and extra-dimensional physics.","one_line_summary":"5D rotating PBHs in the Dark Dimension with memory burden produce a stochastic GW background peaking at nHz to Hz frequencies, detectable by future observatories within the mass window 10^10 to 10^21 g.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The assumption of a log-normal primordial power spectrum with fixed σ=1 and f_PBH=1, together with the memory burden exponent p=2 applied to 5D rotating black holes, which directly sets the amplitude and shape of the computed GW spectrum.","pith_extraction_headline":"Rotating five-dimensional primordial black holes produce a stochastic gravitational wave background detectable by LISA and DECIGO that could confirm a micron-scale extra dimension, PBH dark matter, and memory burden suppression."},"references":{"count":100,"sample":[{"doi":"","year":1974,"title":"Bernard J.
