Modern physics describes the Universe as a vast, expanding entity of spacetime that interacts with matter to produce observable phenomena like gravity.

Cosmology integrates subatomic particles and cosmic structures, showcasing the universe's evolution through Einstein's theories of General Relativity and the Friedmann equation.

Einstein's General Relativity, though less understood, fundamentally reshapes our conception of gravitation, moving beyond Newtonian physics to a nuanced understanding of spacetime.

Space itself exists independently of dark energy, posing questions about their mutual relationship and the fundamental nature of the universe.
