it would be ironic if an instrument built to detect something as vast as astrophysical sources of gravitational waves inadvertently detected the minuscule graininess of space-time.
一台原本用来探测引力波的天体物理来源这类庞然大物的设备却在漫不经心间发现了小到不能再小的时空微粒,这很具讽刺意味。
although there are large numbers of sources of gravitational waves in the universe, the gravitational waves coming from celestial sources are too weak on our earth.
宇宙中虽然存在大量的天体引力波源,但传到地球上的信号都很弱。
also, pairs of massive black holes in the process of merging are expected to be the most powerful sources of gravitational waves in the universe.
此外,正在合体的黑洞配对们有望成为宇宙中引力波最强的来源。
