A Big Bang conundrum

I’ve been interested in theories related to the origin of the universe
for quite some time, and have spent hours consuming information on the
subject through newspaper clippings, television shows and the wealth of
knowledge offered online. I often find presented theories to be flawed,
and have trouble reconciling some perceived problems. I’ve collected the
topics that I take issue with in this essay and would like to hear your
thoughts -- it seems to me that observations of deep space indicate the
long-discounted steady-state universe theory makes more sense than the
popular Big Bang model.

The basic flaw in the Big Bang model of the universe lies in what
happened after the universe formed, when it was much smaller than it is
now, and contained about 80 billion young galaxies as it expanded. What
astronomers see in deep field space is the observable universe as it was
at the time when light rays were emitted 13 billion to 14 billion years
ago. According to the Big Bang model, 13-billion-years-old light rays
can be seen looking in all directions from any point on the globe from
the observer’s position within the Milky Way galaxy. But that doesn’t
jibe with the expansion time line. During 13 billion years of expansion,
the Milky Way galaxy moved 13 billion light years away from the location
of the young and small universe. Now, in the present location, observers
are looking back to where the Milky Way came from and seeing light rays
from galaxies that were also located in that small universe. So far,
this can still make sense, as long as the Milky Way was traveling near
parallel to the light and at a velocity near the speed of light, just to
stay ahead, and 13 billion years later, intercept the somewhat older
light beams from the emitting galaxy -- which I’ll call "Galaxy A" for
illustrative purposes.

What is confusing you is that you're thinking of the simplistic original
Big Bang model, rather than the modern Inflationary Big Bang model. What
the Inflationary model changes from the original model is that it adds
the concept of "Inflation", which creates an overwhelming expansionary
energy to the Big Bang, within billionths of a second after the BB.

The Inflation energy is so overwhelming that it expanded the Universe
out from smaller than an atom to approximately 85 million light-years by
the time of the CMB emissions, 380000 years later, meaning it expanded
*faster* than the speed of light. That means the universe expanded out
to a diameter of 85 million light-years in only 380,000 years, which is
224 times the speed of light!

After Inflation was over, the expansion slowed down to less than or
equal to the speed of light. Any little fluctuations in the density of
the universe prior to Inflation got expanded out to huge proportions
after Inflation. So this is how large scale structures came into being
inside the universe, because per-Inflationary bubbles became too big
after Inflation to be affected by anything travelling at the speed of light.
