摘要

Every second, millions to trillions of particles of dark matter flow through your body without even a whisper or trace. This ghostly fact is sometimes cited by scientists when they describe dark matter, an invisible substance that accounts for about 85 percent of all matter in the universe. Unlike so-called normal matter, which includes everything from electrons to people to planets, dark matter does not absorb, reflect, or shine with any light. It is ... dark. But if we cannot see dark matter, how do scientists know it is there? The answer is gravity. Astronomers indirectly detect dark matter through its gravitational influences on stars and galaxies. Wherever normal matter resides, dark matter can be found lurking unseen by its side.
