here's a thought. Hubble saw A super nova from a previously unknown galaxy and assumed farthest seen object from us so far.

Now suppose an ET were living in that galaxy. Would they also observe a sky full of galaxies or would there be emptiness to one side as we assume there is a finite distance to the universe.

Assuming a finite (in some sense) universe then, unless the ET was on the very edge of their galaxy, they would still see plenty of points of light - stars, nebulae in all directions. They would probably see galaxies on one side and either no galaxies on the other side or assume dark matter etc was obscuring their view to the other side.

Perhaps?

Sometimes I think we are alone in the universe, and sometimes I think we are not. In either case the idea is quite staggering.

I ask because we are currently limited in our ability to see the most distant of object I begin to wonder if the calculations that astronomers use to measure the weight of the universe when they cant actually see the most distant objects.
