Fast Radio Bursts (FRBs) are millisecond-duration extremely bright radio flashes from cosmological distances, with one-off events and repeaters showing different spectral, temporal, and polarization properties (Petroff 2019; Cordes & Chatterjee 2019; Zhang 2020; Luo 2024). Diverse host environments and energetics challenge standard stellar-evolution and compact-object channels. Magnetars, mergers, and other proposed engines must be finely tuned to match rates, host environments, repetition statistics, and energetics.
The standard model attributes FRBs to magnetars or compact-object mergers in standard hierarchical-galaxy environments. Recovering the observed diversity of host environments (star-forming regions to passive galaxies) and the mix of one-off plus repeating sources requires multiple FRB-progenitor channels with finely tuned formation-rate balance. The model has no clean source for the joint diversity.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, FRBs come from cascade-seeded compact-object signatures plus collision injection physics. The cascade collision energy regime (P22, P23) directly produces compact-object seed populations including magnetars and pre-existing SMBH seeds (P46) at the cascade-deposition epoch. Pre-existing matter (P25, P28) supplies the host environments inherited from prior cascade cycles, naturally giving the wide diversity of FRB hosts (star-forming + passive + extreme environments).
Multi-stage cascade dynamics (P36, P37, P38) sets the formation context: cascade-seeded compact objects span a wide range of properties at cascade-end, providing the population diversity that FRB observations show. Repeaters correspond to long-lived cascade-seeded compact objects (magnetars or accreting SMBH seeds) in environments that allow repeated outbursts; one-off events correspond to terminal-merger or violent-disruption events in the cascade-seeded population. The host-environment diversity reflects the wide range of cascade-seeded structures across cosmic environments.
The same M11 framework that resolves the metallicity floor (recid 125), the JWST early-galaxy mass crisis (recid 7, 108), and the broader cascade-seeded compact-object phenomena accounts for FRBs as cascade-seeded signatures. There is no need to invoke fine-tuned multi-channel formation-rate balance. Cascade-seeding produces the diversity naturally.
If precision SKA + ngVLA + CHIME-2 FRB surveys find FRB host distributions and progenitor properties fully consistent with standard stellar-evolution + compact-merger models at the 5% level (no cascade-seeded-population signature), the M11 cascade-seeded explanation is refuted. The signature SCT prediction is the joint host-diversity + repeater-fraction + energetics distribution emerging from cascade-seeded populations rather than from late-time stellar-evolution channels.
