Dark matter makes up ~85% of the universe’s mass yet remains invisible. Let’s explore this cosmic mystery that holds galaxies together.
1
Dark matter doesn’t emit or absorb light—its presence is only seen through gravity’s pull on stars and galaxies.
2
Without dark matter’s gravity, galaxies would spin apart—this “glue” keeps stars orbiting their centers.
3
Weakly Interacting Massive Particles were top suspects for decades—but none have been detected yet.
4
Some theories propose early-universe black holes as dark matter—tiny but numerous cosmic relics.
5
An alternative view: gravity itself behaves differently on cosmic scales, mimicking dark matter’s effects.
6
Recent ideas blend dark matter and energy into a ‘negative mass’ fluid—pushing and pulling on the cosmos.
7
Colliders like the LHC, next-gen telescopes, and gravitational wave detectors keep searching for clues.
8
Dark matter remains one of physics’ greatest puzzles—its discovery could rewrite our understanding of the universe.
