To demonstrate the physical reality of gravitational waves, consider the example system of the previous section. We will concentrate our attention on three of the test masses, one chosen arbitrarily from the plane, along with its nearest neighbors in the +x and +y directions. Imagine that we have equipped the mass at the vertex of this “L” with a lamp that can be made to emit very brief pulses of light. Imagine also that the two masses at the ends of the “L” are fitted with mirrors aimed so that they will return the flashes of light back toward the vertex mass. The Child of General Relativity.
