WebFeb 21, 2016 · And this is because the weak field approximation which reduces EFE to linearized holds very well at such distances and these describe that the gravtiational waves will be transverse. I've read that you also get longitudinal components predicted by the non-linearized EFE equations- although these don't actually propagate? WebThis section discusses how we can discover which waves are real and which are “fake,” and how going to the so-called “transverse-traceless” gauge focuses our attention on the real physical of gravitational waves and how they a↵ect …
