If two people were floating near, say, a pair of merging black holes, the space between them would grow and shrink as space - time was stretched and
distorted by gravitational waves.
Not exact matches
By cross-correlating the arrival times of all the different pulses to nanosecond precision across decades, astronomers hope to detect
gravitational waves with wavelengths measured in light - months and light - years as their passing periodic ripples
distort spacetime around Earth.
What scientists really wanted, however, was a direct detection - to observe the
distorting effect of a
gravitational wave emitted
by a celestial object that has travelled across the universe and then passed through the Earth.
