Astronomers Discover a Group of Quasars 4 Billion Light Years Across

All this observation really implies is that the true and full size of the universe is much larger than what has been documented so far.

Currently, we can observe a bubble of space around us to a radius of about 13.5 billion light years. That's as far as we can see. This may well be analogous to being at the center of a water balloon, submerged in a swimming pool of much greater volume.

We can currently see to the inner surface of that balloon, but the far greater mass of water outside of it remains hidden for now to our instrumentation.

Complex systems will always tend to appear homogenous, given enough subjective distance.

Fun fact: The rotational period of the Milky Way is approximately 200-250 million years.

The universe we currently observe is approximately 13.5 billion years old --- there is no way a spiral of such definition could form after only 50-odd rotations, and yet still be so topographically distinct from other such bodies.

That's simply not enough time.
