Dark Matter: The Invisible Mass Holding Galaxies Together

Dark matter makes up about 27% of the universe, yet it can’t be seen directly.
It doesn’t emit, absorb, or reflect light—making it completely invisible.
Galaxies rotate so fast that without dark matter, they would fly apart.
Its gravity acts like cosmic glue, holding galaxies and clusters together.
Dark matter was first hinted at in the 1930s by astronomer Fritz Zwicky.
Scientists detect it indirectly through gravitational effects on visible matter.
It may be made of exotic particles that barely interact with normal matter.
Massive detectors buried underground search for rare dark matter interactions.
Despite decades of study, no one knows exactly what dark matter is.
Unlocking its mystery could transform our understanding of the universe.
