👉 "World-like" in physics refers to a system that has properties similar to those of a large, homogeneous, and isolated universe. These properties include:
1.
Uniformity
: The state of the system should be uniform across all parts, even in the vicinity of other objects.
2.
Conservation of Mass
: The total mass of the system remains constant over time. This is important for understanding how forces act on an object.
3.
Conservation of Energy
: The energy (mass
