“Local” universe? Has another been discovered and I missed the news flash?

[Telepathic Intruder]

Local universe is another term for visible universe, which extends to the visible horizon, the point where cosmic expansion exceeds the speed of light, and we can never see beyond it by any means known to physics. That's a distance of about 14 billion light years as we observe it, but has by now expanded to about 42 billion light years away. The farthest we can see with visible light is just short of that by about 300,000 light years, and known as the particle horizon. This is the point shortly after the start of the Big Bang when space became transparent.

But the point is that the local universe is probably very small compared to the rest of it outside the visible horizon.

There are local parts of the universe, and more distant parts. No need to invoke other universes. The local universe is that part of our universe within a billion light years. (Source)
