If inflation moves point A so far from point B right after the Big Bang that you can’t get to A from B now, then could the matter and energy in all the parts of the universe that we can’t access (because they’re too far away) provide the missing 90+% of the universe that we can’t account for?
“Inflation” relates to space itself (i.e. space-time). The very fabric of the universe expanded. For example, blow up a balloon half way and draw some spots on it. Then, blow it up fully. You’ll see everything has expanded, the spots as well as the distance between the spots.
Viewing the universe is looking back in time. The further away an object is, the older it is because it takes longer for its light to reach you. The WMAP and Planck Cosmology Probe captured microwave images of the universe when it was only about 370,000 years old, or about 13.7 billion years ago. So, dark matter and dark energy – whatever they are – shouldn’t be beyond our technological vision. We call them “dark” because we can’t scientifically explain the phenomena yet.
