In addition, Professor Michael Longo of the University of Michigan has claimed that the rotation of spiral galaxies is not random, whichwould force a major rethink of cosmology if it were correct.

另外，来自密歇根州大学的教授MichaelLongo 称："螺旋星系的运动轨迹不是随机的"，如果这一理论属实，现有的宇宙学理论就必须被大幅度地重新考虑。

In visible light these galaxies are hidden by dust in IC 1805 and were unknown until 1968 when Paolo Maffei found them using infrared observations.
