I guess this visualisation is at least fine to imagine how light has to travel through spacetime: http://www.esa.int/var/esa/storage/images/esa_multimedia/images/2015/09/spacetime_curvature/15576375-1-eng-GB/Spacetime_curvature.jpg

For me, the problem is space vs spacetime. In LIGO, the recombined waves of light show offsets due to different path lengths. So this seems to be a differential distortion of *space *as the wave passes. So what has *time* got to do with the phenomenon? AG On Friday, January 12, 2018 at 3:13:37

For all those speaking German: This is a quite sophisticated podcast episode about gravitational waves: https://raumzeit-podcast.de/2016/02/18/rz061-gravitationswellenastronomie/. Am Freitag, 12. Januar 2018 10:10:52 UTC+1 schrieb agrays...@gmail.com: > > What exactly is waving? Space-time?
