Thus we cannot see the furtherest galaxies, though we know from empirical evidence and deduction that they must be there, as there are echoes of the mass imprinted on the background.

About that, looking outside of our observable Universe is trivial if we start considering information, in this case memory is the key.

All we have to do is to send a telescope near the edge of our observable sphere.  The telescope will have it's own observable sphere, and some of that sphere will be outside of ours.  So, the telescope can look for us outside of our own observable Universe, then re-transmit all to us.  Same as in the ancient times, when people used to use smoke signals, or shouting orders from one to another in the battle.

Hard in practice to have an outpost at the edge of the Universe, but perfectly doable in theory.   ;D

Since information can travel at most at the speed of light, by the time that information from the telescope arrives to us, our own observable universe has expanded to cover the telescopes observable universe at the time it sent the transmission.

So no, that won't work.

The volume of the universe we can observe expands at the speed of light.  This has nothing to do with inflation, but just the fact that information travels at light speed.

You can shift the sphere of the universe you can observe by moving, and observe things before others elsewhere in the universe, but when you transmit any information, by the time the information can arrive anywhere, the observable universe at the destination has expanded to cover the volume the information is about.  You can do a simple flat 2D model of this, and visualize it easily; in 3D, it is a bit mind-boggling.
