Dark Forces Dominate Universe
The Earth，moon，sun and all visible stars in the sky make up less than one percent of the universe．Almost all the rest is dark matter and dark energy, unknown _1_ that puzzle astronomers．
Observations in recent years have changed the basic understanding of how the universe evolved and have emphasized for astronomers how little is known _2_ the major forces and substances that shaped our world．
Astronomers now know that luminous matter-stars．planets and hot gas – _3_ only about 0.4 percent of the universe．Non．1uminous components．such as black holes and intergalactic gas，make up 3.6 percent．The rest is either dark matter, about 23 percent，or dark energy, about 73 percent．
Dark matter, sometimes called “cold dark matter,” has been known for some _4_. Only recently have researchers come to understand the pivotal role it _5_ in the formation of stars, planets and even people．
“We owe our very existence to dark matter,” said physicist Paul Steinhardt and a co-author of a review on dark matter which appeared not long _6_ in the journal Science．
