越来越多的证据表明，宇宙中多达 90% 的质量是不发光的，并且像光环一样聚集在各个星系周围。据推测，这种暗物质的引力导致了螺旋星系盘中恒星和气体的高旋转速度。目前，暗物质的形态尚不清楚。可能的候选者的质量范围为 1070，从非零质量中微子到大质量黑洞。
There is accumulating evidence that as much as 90 percent of the mass of the universe is nonluminous and is clumped, halo-like, around individual galaxies. The gravitational force of this dark matter is presumed to be responsible for the high rotational velocities of stars and gas in the disks of spiral galaxie. At present, the form of the dark matter is unknown. Possible candidates span a range in mass of 1070, from non-zero-mass neutrinos to massive black holes.
