Dark energy has been mostly thought of as a cosmological constant, which doesn’t look good for the Big Crunch theory’s validity.

暗能量通常被认为是宇宙学常数,这看起来不利于大挤压理论的有效性。

In 1917 he began working on what he termed the 'cosmological constant', a theory which supposed the existence of a static universe.

1917 年,他开始研究他所谓的“宇宙常数”,该理论假设静态宇宙的存在。

Look at Dr. Saul Perlmutter up there, clutching that Nobel Prize.What's the matter, Saul? You afraid someone's going to steal it? Like you stole Einstein's cosmological constant?

跟马修学英语

There is a theory that there may be a type of energy fluid out there somewhere filling space or perhaps Einstein's Theory of Gravity should include a cosmological constant or maybe it's wrong altogether.

有一种理论认为,在某个地方可能存在一种能量流体充满了空间,或者爱因斯坦的引力理论应该包括一个宇宙常数,或者它可能完全错误。

宇宙学常数

Full-sky image derived from nine years' WMAP data
Estimated ratios of dark matter and dark energy (which may be the cosmological constant) in the universe. According to current theories of physics, dark energy now dominates as the largest source of energy of the universe, in contrast to earlier epochs when it was insignificant.

宇宙学常数(cosmological constant)或宇宙常数由阿尔伯特·爱因斯坦首先提出,现前常标为希腊文「Λ」,与度规张量相乘后成为宇宙常数项\Lambda g_{\mu\nu}而添加在爱因斯坦方程序中,使方程序能有静态宇宙的解。若不加上此项,则广义相对论所得原版本的爱因斯坦方程序会得到动态宇宙的结果。

这是出于爱因斯坦对静态宇宙的哲学信念。在哈伯提出膨胀宇宙的天文观测结果哈伯红移后,爱因斯坦放弃宇宙学常数,认为是他「一生中最大的错误」。

但是1998年天文物理与宇宙学对宇宙加速膨胀的研究则让宇宙学常数死而复生,认为虽然其值很小,但可能不为零。宇宙常数项的贡献被认为与暗能量有关。

Cosmological constant 宇宙学常数

Estimated ratios of dark matter and dark energy (which may be the cosmological constant) in the universe. According to current theories of physics, dark energy now dominates as the largest source of energy of the universe, in contrast to earlier epochs when it was insignificant.

In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ) is the value of the energy density of the vacuum of space. It was originally introduced by Albert Einstein in 1917 as an addition to his theory of general relativity to "hold back gravity" and achieve a static universe, which was the accepted view at the time. Einstein abandoned the concept after Hubble's 1929 discovery that all galaxies outside the Local Group (the group that contains the Milky Way Galaxy) are moving away from each other, implying an overall expanding universe. From 1929 until the early 1990s, most cosmology researchers assumed the cosmological constant to be zero.
