As we look at larger and larger scales in the universe, what do astronomers find?

Answer 1

Larger and larger aggregations.

The Milky Way galaxy, of which the Solar system is a part, can be combined with other galaxies to form a local cluster, which can then be combined with still more galaxies to form a super cluster, and so on. The universe itself is the ultimate super set.

Astronomers find that the universe appears to be homogeneous and isotropic on large scales, meaning it looks the same in all directions and at all points. They also observe the large-scale structure of the universe, including galaxy clusters, filaments, and voids, which are organized into a cosmic web-like structure. Additionally, they find evidence for the accelerated expansion of the universe and the presence of dark matter and dark energy.
