质量M BH < 109 g的超轻原初黑洞在大爆炸核合成之前蒸发，产生所有的物质场，包括暗物质，特别是超重暗物质：M DM 1010 GeV。如果暗物质通过U（1）破缺获得质量，那么赋予暗物质质量的相变也会产生辐射引力波的宇宙弦。由于破界尺度ΛCS与M DM的量级相同，宇宙弦辐射的引力波具有足够大的振幅，可以在现有和计划中的实验设施可以探测到的所有频率上探测到。此外，早期原始黑洞统治的时代在引力波频谱中引入了独特的频谱中断，其频率与超重暗物质质量有关。因此，原初引力波的随机背景特征可能表明超重暗物质起源于原初黑洞。从这个角度来看，最近通过两个纳米频率脉冲星计时阵列发现了许多恒星的随机共谱过程，这将使暗物质的质量固定为3 × 1013 GeV-1014 GeV。在0.2 Hz处（未）检测到频谱中断将（排除）证实信号的这种解释。
Ultra-light primordial black holes with masses M BH < 109 g evaporate before big-bang nucleosynthesis producing all matter fields, including dark matter, in particular super-heavy dark matter: M DM ≳ 1010 GeV. If the dark matter gets its mass via U(1) symmetry-breaking, the phase transition that gives a mass to the dark matter also produces cosmic strings which radiate gravitational waves. Because the symmetry-breaking scale ΛCS is of the same order as M DM, the gravitational waves radiated by the cosmic strings have a large enough amplitude to be detectable across all frequencies accessible with current and planned experimental facilities. Moreover, an epoch of early primordial black hole domination introduces a unique spectral break in the gravitational wave spectrum whose frequency is related to the super-heavy dark matter mass. Hence, the features of a stochastic background of primordial gravitational waves could indicate that super-heavy dark matter originated from primordial black holes. In this perspective, the recent finding of a stochastic common-spectrum process across many pulsars by two nano-frequency pulsar timing arrays would fix the dark matter mass to be 3 × 1013 GeV ≲ M DM ≲ 1014 GeV. The (non-)detection of a spectral break at 0.2 Hz ≲ f * ≲ 0.4 Hz would (exclude) substantiate this interpretation of the signal.
