Using Gravitational Waves to Find New Physicists

The frequency of the gravitational wave is determined by how fast the black holes are moving around each other, which depends entirely on the forces between them. So we could use gravitational waves as a probe to look for new physics - things with that we do not yet understand. We want to break the cognitive shackle of being here on earth and be creatures of the universe. Unfortunately, we are trapped here on the earth and can only use the signals that get here. But at the very least we should pay careful attention to those signals. Even if they are little hints from pulsar timings that something weird is going on in the space between us and the pulsars.
