如果宇宙不小于10 ^{10}$ yr，哈勃常数不小于50 km/sec/ Mpc，那么在星系团中，波长很长的宇宙引力波现在不能产生比这些系统随着宇宙膨胀时所具有的速度色散更大的速度色散。图表显示实际的速度分散明显大于这个极限。
Very long wavelength universal gravitational waves cannot now produce in clusters of galaxies velocity dispersions greater than that which these systems would possess if they were expanding with the Universe, if the Universe is not younger than $10^{10}$ yr and Hubble's constant is not less than 50 km/sec/ Mpc. A diagram shows that actual velocity dispersions are significantly greater than this limit.
