CLOSED UNIVERSE Meaning and
Definition
-
A closed universe refers to a theoretical model in cosmology that depicts the entire universe as a finite, bound entity. In this model, the universe has a specific shape or geometry, which is typically described as closed or spherical. The term "closed" here implies that the universe forms a closed loop or has no boundaries, similar to the surface of a sphere.
In a closed universe, the geometry of space is positively curved, meaning that the sum of the angles of a triangle exceeds 180 degrees. This curvature causes light and objects to follow curved trajectories, ultimately leading back to their initial positions in a cyclic manner. Consequently, if someone were to travel in a straight line for a sufficiently long distance, they would eventually return to their starting point.
The concept of a closed universe has profound implications for cosmology, as it suggests that the universe is finite in both space and time. According to some theoretical models, a closed universe could result in a cyclical pattern of cosmic expansion and contraction, where the universe undergoes successive cycles of birth, expansion, collapse, and rebirth.
While the idea of a closed universe has been largely superseded by the notion of an expanding universe driven by dark energy, it still remains a subject of theoretical investigation due to its fascinating implications for the nature and ultimate fate of the cosmos.

Etymology of CLOSED UNIVERSE
The word "closed universe" is a term primarily used in physics and cosmology to describe a hypothetical model of the universe. Its etymology can be broken down as follows:
1. Closed: The term "closed" stems from the Latin word "clausus", which means "closed" or "shut". In physics, a closed system refers to a system that does not exchange matter or energy with its surroundings.
2. Universe: The word "universe" has its roots in Latin as well, composed of two parts: "uni-" meaning "one" or "as a whole", and "versus" meaning "turned". It refers to the entirety of space, time, matter, and energy that exists.
When combined, the term "closed universe" refers to a cosmological model where the universe is finite in size, closed, and self-contained.
