an arbitrary constant in the equations of general relativity theory

However, the small cosmological constant and cosmic coincidence problem cannot be resolved within the known laws of physics, which is the famous cosmological constant problem in physics and astronomy.

然而现有物理学理论还无法给出合理的解释，因此宇宙学常数问题成为物理学和天文学上最重大的疑难之一。

The physical origin of the cosmological constant is considered to be one of the most difficult and important problems in modern physics.

当代天文学的一系列观测事实都支持应该存在一个非零的正的宇宙学常数 。

In 1998 astronomers discovered that the universe's expansion is accelerating at a rate consistent with a cosmological constant 10-120 times the value predicted by quantum theory.

天文学家于1998年发现到宇宙正在加速膨胀，但其加速度所对应到的宇宙常数，却是量子理论预测值的10- 120倍。

Both the cosmological constant and quintessence fall into the general category of dark energy.

不管是宇宙常数还是第五元素，都属于暗能量的？畴。

The fact that this point is an attractor on the diagram is another way of understanding the cosmological constant problem.

事实上，这一点是吸引上图是另外一个问题的方式理解宇宙常数。

The two dimensional theory of induced gravity with cosmological constant is quantized in the superspace approach.

本文用超空间方法对其有宇宙学常数的二维诱生引力进行量子化。

Einstein called the something the cosmological constant and added it to his theory with some distaste, because the work had been so mathematically beautiful without it.

爱因斯坦将其称为宇宙常数，并略带厌恶地将它加入他的理论，因为如果没有宇宙常数，它的理论在数学上优美极了。
