In this multiverse theory, you have a static universe in the middle.

在这个多元宇宙理论里，你假设在中间有一个静止的宇宙。

So that static universe in the middle has time as a coordinate but there's no arrow of time.

所以这个处于中间的静止的多元宇宙具有作为坐标的时间，但是没有时间之箭。

Because Einstein thought he needed to model a static universe, he introduced his "cosmological fudge factor" to balance the attractive gravity of matter.

因为爱因斯坦当时认为他需要建构一个静态的宇宙，因此引入一个假想的宇宙参数来平衡物质间的重引力。

Thus, Einstein introduced his cosmological constant as an ad hoc factor in his equations, in order to conform with observational cosmology of the era which called for a static universe.

FORBES: Dark Energy Camera Could Reshape Einstein Cosmology

After Hubble published his findings in 1929, he, Einstein, British astronomer Sir Arthur Stanley Eddington, and Dutch astronomer Willem de Sitter, all gathered at a special meeting of the Royal Astronomical Society and pondered how they could account for such developments based on static universe models that Einstein and de Sitter had derived with General Relativity.
