Asymptotic behavior of null geodesics near future null infinity: Significance of gravitational waves
Asymptotic behavior of null geodesics near future null infinity: Significance of gravitational waves
We investigate the behavior of null geodesics near future null infinity in asymptotically flat spacetimes. In particular, we focus on the asymptotic behavior of null geodesics that correspond to worldlines of photons initially emitted in the directions tangential to the constant radial surfaces in the Bondi coordinates. The analysis is …
