Steve,
Thanks very much for your LIGO link. Contains other linked sites and I think it is a must read for everybody...
- Light can be polarized; Gravitational waves can be polarized.
- Light travels at c; Gravitational waves travel at c.
- Observations from the BICEP2 telescope at the South Pole demonstrates that gravitational waves were abundant in the early universe; Observations reveal an abundance of light radiation in the early chapter of our universe's history, the relic glow is called the cosmic microwave background.
- Gravitational waves are vibrations that cause the distance (space) between objects to change in an oscillatory manner, and this will change the type of interference pattern in LIGO. In short, gravitational waves propagate as vibrations of space.
If we now apply the famous principle of reductio ad absurdum or its corollary (increase to coherence and common sense), and going by the precedence set when Light was termed an electromagnetic wave, because Maxwell's theory found that electromagnetic waves will travel at c and light travels at c. It follows from the foregoing that with the similarities between Gravitational waves and Light,
*In the vast emptiness of space, Light should also be a vibration in space (or space-time for some) since it also travels at c.
*Space is therefore not a nothingness, but something that can be made to vibrate and propagate waves.
* Space can react, and from the action-reaction principle, only things that can act, can also react.
I end with some quotes from that great son of humanity:
"...it is clear that philosophers would cheerfully allow space to be substance, just as body is, if only extension could move and act as body can" (General relativity now supports that space can react), "...space is capable of having some substantial reality. Indeed, if its parts could move..., and this mobility was an ingredient in the idea of vacuum, then there would be no question about it - parts of space would be corporeal substance" (If space now has a reality, then the Platonic point, line and surface are not fictions as mathematicians would have us believe), "And my account throws a satisfactory light on the difference between body and space. The raw materials of each are the same in their properties and nature, and differ only in how God created them..." (ultimately therefore the fundamental constituent of both body and space will be one, the Monad) - Sir Isaac Newton, De Gravitatione et Aequipondio Fluidorum.
Moral 1. The stone the builders refused will return to be the head cornerstone. Moral 2. Any wrong theory, no matter how twisted to fit contains the seed of its own destruction.

(Take note that I am not a supporter of inflation theory and I can provide irrefutable arguments if asked. But I believe the universe had a beginning. Also, although this thread says 'Ripping Einstein Apart', I am his supporter, but not a fanatical and blind one. As Newton would say, Euclid is our friend, Plato is our friend, Galileo is our friend but our greatest friend should be Truth).
