NAME GRAVITATIONAL WAVES
TYPE ASTROPHYSICAL
DESCRIPTION
Gravitational waves are perturbations of space-time caused by the creation or 
              destruction of mass.  Although detected using the Laser Interferometer Gravitational-wave 
              Observatory (LIGO), they had not been observed using radiometric techniques as of 2019.
