For a gravitational wave to be unambiguously identified, it must be detected by more than one instrument. 鑒于重力波顯而易見(jiàn)的研究地位，必須投入更多的儀器來(lái)進(jìn)行研究。
If a wave passes between you and a pulsar, it will alternately stretch and compress the distance between pulses, so the blinking will appear to slow down and speed up. 脈沖星這種恒星會(huì )發(fā)出像原子鐘般規律的閃光，要是重力波從你和脈沖星之間穿過(guò)，它便會(huì )交互拉長(cháng)和壓縮脈沖及脈沖之間的空間，閃光于是跟著(zhù)減速和加速。
That is why gravitational waves are so difficult to detect! 這就是為什么引力波的探測如此困難的原因。
These spacetime distortions travel as gravitational waves. 這些時(shí)空的改變以引力波的形式傳遞。
