宇宙常数 1917年，爱因斯坦利用他的引力场方程，对宇宙整体进行了考察。为了解释物质密度不为零的静态宇宙的存在,他在场方程中引进一个与度规张量成比例的项,用符号Λ表示。该比例常数很小，在银河系尺度范围可忽略不计。只在宇宙尺度下，Λ才可能有意义，所以叫作宇宙常数。1929年，哈勃发现星系红移的哈勃定律，确定静态宇宙模型与实际不符。因此爱因斯坦多次提出应该取消宇宙常数；但有些学者，如爱丁顿、德西特、泽尔多维奇则认为宇宙常数可能有新的物理意义，不宜轻易抛弃。目前，学者们对宇宙常数的看法并不一致，有的认为是正值；有的认为是负值；有的认为是常数；有的则认为它随时间而变化。但多数倾向于取正值，其物理意义可能代表宇宙真空场的能量－动量张量与可能存在于物质之间的斥力。估计宇宙常数的上限为10-57厘米-2。
