Re: Is the inflationary model of the universe true?
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.

Re: DA.
Currently there is no scientific evidence that indicates our universe is finite. How would we know? There would be the possibility that if we looked far enough we could see our own galaxies at an earlier time in the Big Bang timeline (kind of like being able to see the back of your house if you had a strong enough telescope that could look across the curved surface of the Earth).
This is not possible in a classic closed FRW universe. Collapse will always occur before a light ray can circumnavigate the space-time. A closed FLRW universe (i.e. with constant dark energy) could have this possibility (the ESU being an obvious example where it would work), but our own inflated and young Universe has zero chance of having had the possibility of a circumnavigated photon, even if finite. Topological compactification could lead to this effect, but so far we've found evidence of this in neither galaxy/quasar surveys nor the CMBR itself.
