...it sez here. Interesting, interferometry? Dunno yet. Thanks fieldmarshaldj.
Be funny if we discovered someday that it’s all just a trick done with mirrors.

Fixed it. Darn...
The universe is immensely big but it is not infinite. One way we know that is that the night sky is not bright with light from an infinite expanse of galaxies and stars.
Then again, perhaps, there are dust clouds obscuring the light ... its never safe to make assumptions about what is or is not in the universe.
Most use 100-200 billion as the number of galaxies in the universe others say the real number is closer to 2 trillion ... just depends on who looks and how they are counted. But 300 thousand is just a rounding error, even though the group contains trillions of individual stars
Dust clouds are usually not impenetrable to all frequencies and would not negate the effect.

Key word: usually.
But optically (visually) the dust would hide all behind it, and the rest of the universe has not been completely (or even close) surveyed with non-optical instruments.
Maybe the universe is a sphere and eventually we will see our own backside and think it’s still out front....

In practice, when we turn a telescope to intergalactic space and see a galaxy with a telescope, we see more and more galaxies beyond it as we deploy more powerful telescopes. If we lived in an infinite universe endlessly stuffed full of galaxies and stars, it seems logical that we would not see darkness between galaxies or a dark sky at night. The nighttime sky would be more like a cloudy winter at dusk, and distant galaxies would be hard to discern against the light of the distant cosmos.
There are more complicated, math reliant arguments against an infinite and unlimited universe, but the point about dark skies seems easiest to establish.
There are supposed to be 2 trillion galaxies in the observable universe, so 300,000 is not a big increase.
