There are multiple ways to resolve loops during universe building.
One way is to use aggregate awareness to avoid loops.
Another way is to use aliases to create a self-join.
A third way is to use contexts to define the scope of the query.

Water does not fall from a filled glass because of surface tension and gravity.
Surface tension of water creates a force that holds it together and prevents it from overflowing.
Gravity pulls the water downwards, keeping it inside the glass.
The shape of the glass also plays a role in containing the water.
If the glass is filled beyond its capacity, the surface tension may break and water will overflow.
