"According to general relativity, every gravitational wave should
leave an indelible imprint on the structure of space-time. It should
permanently strain space, displacing the mirrors of a 
gravitational wave
detector even after the wave has passed.
Since that first detection almost six years ago, physicists have been trying to figure out how to measure this so-called “memory effect.”
“The memory effect is absolutely a strange, strange phenomenon,” said Paul Lasky....in general relativity, where space-time is stretched and squashed in different directions depending on the motions of bodies, a potential dictates more than just the potential energy at a location — it dictates the shape of space-time.Q: How, exactly, will a passing wave distort space-time?
A: The possibilities
are literally infinite, and, puzzlingly, these possibilities are also
equivalent to one another." Quanta/KM
