Many contemporary models of the Big Bang from The Hartle Hawking model to Loop Quantum Cosmology to String Gas Comsology, the Janus Universe, Carroll Chen, Aguirre-Gratton, and CPT symmetric universe, can be interpreted as giving the universe an hourglass-like structure. In this episode of the SciPhi Show, leading atheist philosophers Alex Malpass and Dan Linford examine what this might mean for the Kalam Cosmological Argument. In particular, we show that it faces an "interface dilemma" where defenders of the argument, like William Lane Craig, must give up one of the Kalam's fundamental premises.
