Why can the structure of the universe be compared to soap bubbles?

Answer 1

Excellent question! On the very largest scales we observe that clusters and super-clusters of galaxies exist around voids.

When viewed from a distance, the galaxy distribution is not as random as one might think: it appears to be in a web, similar to a spider's in two dimensions, or in bubbles in three dimensions. This is consistent with predictions made by the most popular cosmological theories, including LCDM.

The structure of the universe can be compared to soap bubbles because both exhibit similar characteristics at a large scale, such as spherical shapes, interconnectedness, and the presence of voids or spaces between them. Additionally, both soap bubbles and the universe are influenced by surface tension or gravitational forces, respectively, which shape their overall structure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
