Understanding Dark Matter

Dark matter, a mysterious component of our universe, comprises the majority of the universe's mass. While regular matter, like stars and planets, accounts for only 4-5% of the universe, dark matter remains invisible and interacts solely through gravity. Research suggests that dark matter plays a vital role in the formation of galaxies by serving as a stabilizing force. Scientists like Priyam Vata Natarajan conduct observations and simulations to indirectly study dark matter, emphasizing the humbling realization of humanity's limited understanding of the universe's composition.
