星系外环应以可以观测到的速度被甩入太空，因为星团的质量不足以通过万有引力来束缚星系的边缘部分。
At the observed speeds, the outer galaxies should be flung out into space, since the clusters don't appear to have enough mass to keep the galaxies at their edges gravitationally bound.
并在1933年首次提出解释星系外环在星团轨道上的转速比基于星系可见物质而得出的理论转速要高的概念。
The concept was first proposed in 1933 to explain why the outer galaxies in galaxy clusters orbit faster than they should, based on the galaxies' visible mass.
虽然精确地点未知，但梅斯·温杜指出，它散布在银河系最遥远的地带，这就使得外环诸星系成为可能的选择。
The exact locations are unknown, but Mace Windu stated that it was separated into the farthest reaches of the galaxy, making Outer Rim systems likely choices.
