Dark matter and dark energy make up most of the universe, yet they remain some of the biggest mysteries in physics. Dark matter acts as an invisible glue, holding galaxies together, while dark energy drives the universe's rapid expansion. Scientists study their effects by observing gravitational lensing and cosmic background radiation.
Although dark matter does not emit light, its presence is inferred through galaxy rotation and large-scale cosmic structures. Dark energy, on the other hand, accelerates the expansion of space, counteracting gravity. Research into these forces could revolutionize our understanding of the cosmos.
