WELL, THERE IS EITHER SOMETHING (WHICH WE CANNOT NAME) OR AT THE VERY LEAST A BOUNDARY WHICH NOW LIES AT THE MARGIN OF OUR CURRENT UNIVERSE.
Neither. If the Universe is infinite, this is trivially true. If the Universe is not infinite, it is compact and has no boundary (similarly for the surface of a sphere)
ONCE INFLATION BEGAN, THERE WOULD BE NO "ZERO SPACE" AND ONCE THE SINGULARITY BEGAN REACTING (INFLATING) AT THE INTERFACE, MORPHING TO PROGRESSIVE ENTROPY WOULD COMMENCE. THUS ENORMOUS ENERGY ADMIXED IN CHAOS WITH FOCAL HARMONICS GUIDED BY NON-EQUILIBRIUM THERMODYNAMICS WOULD INEVITABLY PROGRESS TO "THE BITS AND PIECES" (STRINGS AND MEMBRANE "COMPONENTS") OF PRIMORDIAL MATTER.
Meaningless word salad.
NOTHER 300,000,000 YEARS (OR SO) AND THE FORCES NOW SEPARATED AND THEIR DOMAINS WELL ESTABLISHED. EVENTUALLY YOU HAVE PROTONS
Protons formed in the first microsecond of the Universe. Neutral hydrogen appeared around 400,000 years later in the period known as recombination, causing the Universe to become transparent to light. The very first photons to move freely through the Universe are still seen today as the Cosmic Microwave Background Radiation.
