Patricia Burchat解释暗物质

Ordinary matter, the kind that forms stars, planets, and people, makes up just a tiny fraction of the universe. The rest consists of dark matter and dark energy, mysterious entities that cannot be directly seen or measured yet control the universe's structure and fate. Evidence for dark matter comes from galaxy motions and gravitational lensing, while dark energy is revealed by the accelerating expansion of space. Together, these unseen ingredients account for 96% of everything, challenging scientists to find new ways of understanding reality.
