If you had an oscillating boson in a vacuum with an observer some distance away, how would you calculate the energy that the observer receives or loses as a result of experiencing a gravitational wave?

2$\begingroup$ Your title and body are asking two quite different questions. A detector doesn’t absorb all of the energy that passes through. $\endgroup$– G. SmithOct 14, 2020 at 20:12

1$\begingroup$ Are you aware that we can’t detect gravitational waves from individual elementary particles? We can barely detect them from black holes and neutron stars. $\endgroup$– G. SmithOct 14, 2020 at 20:13

$\begingroup$ Also, this answer shows how to calculate the gravitational energy emitted by a 2 body orbital system. $\endgroup$– PM 2RingOct 14, 2020 at 20:38

$\begingroup$ I'm not really asking for a practical application just theoretically for a particle and observer. $\endgroup$– JRRsOct 15, 2020 at 2:07
