Clearly, the most direct way of verifying if this hypothesis corresponds to reality is to measure the vibrational displacement induced in a resonant detector by a passing gravitational wave.
We can then profit from the fact that the vibrational energy induced in a resonant detector, by a gravitational wave, can be converted to the fractional change in vibrational displacement by making use of the relation between amplitude [x.sub.0], energy E and the total mass M for a harmonic oscillator, in the familiar form
