However , physicists inclined to believe that the total mass of the universe will be " just right " , that means it is enough to stop the expansion of the universe at last but is not enough to pull it back . hence , the universe is neither closed nor open but a flat universe 不过,很多物理学家倾向相信宇宙中的物质质量不太多也不太少,膨胀会逐渐缓慢下来,但永远不会收缩,宇宙既非封闭也非开放,而是介乎两者之间的平面宇宙。
