If successful, it would certainly be a major step forward in physics: the ability to produce, detect and, ultimately, control gravitational fields.
The precise agreement between our observations and GR's predictions not only strongly supports the validity of Einstein's theory--at least for the strengths of the gravitational fields probed by the Double Pulsar--but it also puts severe constraints on alternative theories of gravity.
The Lagrangian (L) for this gravitational field can be defined using the metric tensor as:

These results provide a taste of the groundbreaking science that GRAVITY will produce as it probes the extremely strong gravitational fields close to the central supermassive black hole and tests Einsteins general relativity.
