What determines the structure of the universe?
Quick fact
Scientists study the geometry of the universe using physics, mathematics, and observations of cosmic radiation.
Why this is interesting
The universe is not just filled with objects — space itself has a structure and shape.

Understanding What determines the structure of the universe?
The universe may be flat, curved, or have more complex structures depending on how matter and energy influence spacetime.
A deeper explanation
The geometry of the universe is described by Einstein's theory of general relativity, where matter and energy determine the curvature of spacetime. Understanding cosmic geometry helps scientists study the universe's origin, expansion, and ultimate fate.
