What holds the universe together?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Gravity is the primary force holding the universe together on large scales, binding planets to stars, stars to galaxies, and galaxies to clusters. However, the complete picture includes dark matter (providing additional gravitational effects) and dark energy (causing accelerated expansion). On smaller scales, the strong nuclear force holds atomic nuclei together, and electromagnetic force binds atoms into molecules and materials. The universe's structure results from the interplay of all these forces.
