ΛCDM posits a singular Big Bang origin where all spacetime, energy, and matter erupted from an infinitesimal point at t = 0, with no coherent answer to what preceded this moment or what mechanism created it (Guth 1981; Steinhardt 2014). Fundamental questions remain: Why did inflation begin? What set initial conditions? What existed before the Big Bang? The model treats t = 0 as an undefined boundary condition.
The standard model assumes spacetime + energy + matter began at a singular t = 0 event whose physics is undefined. The model has no framework for pre-Big-Bang causation, leaving the deepest cosmological questions philosophically + scientifically unresolved. The answer to what came before is a category error in the standard framework.
SCT replaces the hot-dense-center with a superluminal collision between two pre-existing parent pockets and the thermalized debris field that became our visible universe. From this single change, what forged our patch of spacetime is concrete: a cascade of superluminal pocket collisions roughly 13.8 Gyr ago thermalized the matter inherited from the parent pockets into our observable cosmological patch (P22, P25, P26). Time itself is eternal (P1), so the question of what came before our cascade has a definite answer: parent pockets existed as products of earlier cascade events in an infinite array of cycles (P27, P28).
Before our cascade, the parent pockets that collided to make us were themselves products of earlier cascade events stretching back through eternal time. There is no t = 0 boundary condition; there is no first event; there is no creation from nothing. Each cosmic cycle is a local Big Bang (P26) within the infinite eternal manifold (P1, P2), with matter recycled across cycles through the eternal collision cycle (P28). What forged our patch is mechanism: superluminal collision of pre-existing matter. What came before is mechanism: the eternal cycle of collisions from which our parent pockets emerged.
The cascade thermalization (P22, P23) at peak temperatures T_QCD ≈ 10¹² K and T_EW ≈ 10¹⁵ K in compressed hotspots produced the plasma we now see as the CMB, which evolved under standard physics (P29, P30) into our observable structure. The same M1 framework that resolves the horizon problem (recid 14), flatness (recid 10), hierarchy (recid 6), monopole-absence (recid 21), and the broader cosmogenesis-replacing-by-cascade-thermalization phenomenology accounts for the deepest cosmological-origin questions in mechanistic rather than philosophical terms. There is no creation from nothing because nothing was ever required to come from nothing.
Detection of a definitive observable that requires a singular t = 0 event whose physics breaks down (e.g., unambiguous primordial inflationary B-modes at r > 0.005, or a relic that demands T > T_EW in our patch's history) would refute the M1 eternal-cascade cosmogenesis. The signature SCT prediction is null detection of all such Planck-or-GUT-scale relics consistent with the cascade peak temperature ceiling.
