The universe is 95% shrouded in mystery: dark matter and dark energy. As of March 2025, telescopes and AI-powered simulations are working full throttle to unravel these concepts. xAI contributes to this research, aiding our understanding of the universe’s structure. Dark matter holds galaxies together but is invisible; dark energy accelerates the universe’s expansion. Though science can’t directly observe them, their effects are measurable. Each discovery prompts humanity to question its place in the cosmos. Understanding the dark side might just bring us closer to the light.
