Lambda-CDM 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. The model treats the Big Bang as a boundary condition beyond which physics becomes undefined, offering no framework for understanding causation before the initial singularity. Fundamental questions remain unanswered: Why did inflation begin? What set initial conditions? What existed before the Big Bang? These gaps represent a profound incompleteness in Lambda-CDM's explanatory power, leaving the deepest cosmological questions philosophically and scientifically unresolved (Guth 1981; Steinhardt 2014). The absence of a pre-Big Bang physics or coherent mechanism for universe creation undermines the model's claim to provide a complete description of cosmic origins.
