Passage 2

   Astronomers believe that the expanding universe is the result of an enormous and powerful explosion called the Big BangThe Big Bang theory_may explain how the universe formedThe Big Bang theory states that the universe began to expand with the explosion of concentrated matter and energy and has been expanding ever sinceAccording to the theory,all the matter and energy in the universe was once concentrated into a single placeThis placeof courseWas extemely hot and denseThen some 15 to 20 billion years agoall explosion--the Big Bangshot the concentratedmatter and energy in all directionsThe fastest moving matter traveled farthest awayEnergy,toobegan moving away from the area of the Big Bang.

    If the Big Bang theory is correctthe energy left from the Big Bang will be evenly spread  out throughout the universeThis energy is known as background radiationAnd indeed  universeThe constant background radiation is one observation that supports the Big Bang  theoryAfter the initial B ig Bangthe force of gravity began to affect the matter racing outward  in every directionGravity is a force of attraction between objectsAll objects have a  gravitational attractionThis force of gravity began to pull matter into clumps

At some timethe clumps formed huge clusters of matterThese clumps became the galaxies of the universeBut even as the galaxies were formingthe matter inside the galaxies continued to race away from the area where the Big Bang had occurredAnd this is just what astronomers have discoveredAll of the galaxies are speeding away from the center of the universe.

 

天文学家认为膨胀的宇宙是一次巨大的、强劲的宇宙大爆炸的结果。宇宙大爆炸理论也许能解释宇宙是如何形成的。
