Discover the Universe from Unique Vantage Points | Your Ultimate Guide

In summary, the universe is infinite and homogeneous, with all points seeing the same temperature microwave background and range of visibility. However, due to the expansion of the universe, the observable universe has a radius of around 45 billion light years. The circles we draw to represent our observable universe can overlap, and they do not represent separate physical regions of space. This concept is often misunderstood, leading to misconceptions about the nature of the universe.

Exactly. The exact details of what they see will vary but they will see the same number of galaxies and so forth.
