Title: "The Nonlinear Essence of Gravitational Waves"

Relying on the gauge structure of teleparallel gravity, which allows a more direct comparison with the electromagnetic and Yang-Mills theories, a re-analysis of gravitational wave theory is made. In particular, a study of the energy and momentum carried by gravitational waves is presented. Analogously to a Yang-Mills propagating field, which must be nonlinear to carry its gauge charge, it is argued that a gravitational wave must necessarily be nonlinear to transport its own charge, that is, energy and momentum.
