In a simulated universe, dark matter shows its crucial role by interacting gravitationally with visible matter, impacting galactic and cosmological structures we observe today.
The evidence for dark matter spans multiple scales—galactic, galaxy clusters, and cosmological—rather than only being tied to a single observational framework.
Vera Cooper Rubin’s groundbreaking measurements on the rotation speed of stars in spiral galaxies led to the critical realization that unseen mass was influencing their motion.
Dark matter constitutes about 85% of the universe's matter, as telescopic observations and calculations reveal its significant gravitational influence on normal, luminous matter.
