Ripples in the fabric of space and time ripple in the fabric of space and time….Where two black holes merge,there, undulate and warp and curve violently play,folding and bending the event horizonuntil gravitational wavesburst forth.In cruciform oscillationthey travel the universe unimpededat the speed of light.Echoes of a violent pastthey pass the Earth unseen, unfelt,like laps upon a seashore on a calm day.Our existence unaffecteduntil the winds rev them up to lash our shores,erode our coastlines,reshape our lands,enforced restructuring of lives.Einstein predictedthese faint echoes of past violencenow seen by interferometersas wiggles in a laser beam,their reverberations signallingthe seismic shiftin our understanding of the universethat ripples through the fabric of space and time© Sheila Ash, 20174thOctober 2017 on the announcement of the 2017 Nobel Prize for Physics (https://www.nobelprize.org/nobel_prizes/physics/laureates/2017/press.html)ashramblings
