The point being that we now have imaging capability to detect objects further away than we currently see them, and they aren't there!

If that's the case, and what we see is what we get then that would strike down the point I've been trying to make, which is that space and the particles contained in them go on and on we just don't don't see them.

Just to be clear on this point, we don't see objects beyond a certain distance (roughly 13 billion light years) because that distance corresponds to an early age of the Universe when luminous objects (stars, etc.) first formed. Anything further out would be so far back toward the beginning of the Universe that luminous objects would not have yet formed, and hence no photon's had yet been generated to find their way into our detectors that would allow us to see them.

If our estimates of the age of the Universe were too low, one would expect to continue to find more quasars as we probe out beyong 13 billion light years distance; the fact that they seem to stop at that distance is consistent with what is predicted for a roughly 14 billion year old Universe.
