Boffins' gravitational wave detection hat trick blows open astronomy

The explanation of interference is slightly wrong in the article...

...it's not due to the mirror moving - it's due to the compression / expansion of the fabric of the universe caused by the gravitational wave making one of the laser paths in the 'L' shape a different length to the other, causing the interference pattern to change.

So the detected change is a direct result of the compression/expansion of the fabric of the universe as the gravitation wave passes through the detector site.
