How would you put the Universe to scale?

Answer 1

You can't for a number of reasons.

The image above is a NASA depiction of the universe as we know and see it today. However, astronomers agree that the actual shape of the universe is a sphere, a ball if you will. The entire universe exists on the surface of that ball. The problem is, no one knows where the various galaxies shown above belong on that ball rendering any depiction of the actual universe impossible.

To put the universe to scale, we would typically use the concept of astronomical units (AU) or light-years. For example, the diameter of the Earth would be represented as 1 unit, and then other celestial objects would be scaled accordingly. This allows us to visualize the vastness of the universe relative to familiar objects like planets.
