He&amp;#x27;s bloody Astronomer Royal. I suspect a ghostwriter.&lt;p&gt;a) Gravitational waves do NOT &amp;quot;shake the mirrors&amp;quot;. They make spacetime contract in orthogonal directions around and within the beam tube (and of course elsewhere) thus causing the light to travel a tiny bit further in the tube, thus causing interference by moving the two beams out of phase.&lt;p&gt;b) As I posted the other day - what about Virgo? What about GEO600? I feel really sorry for the scientists who&amp;#x27;ve spent decades working on this as part of a global collaboration to now have LIGO take &lt;i&gt;all&lt;/i&gt; of the credit for this discovery.</text></comment>
