About the Advanced LIGO Rumours and Gravitational Waves (part 2)

Everyone who is familiar with quantum-geometry dynamics knows that it precludes the existence of gravitational waves (if you are not familiar with QGD, see An Axiomatic Approach to Physics for a short introduction to subject). So, one may think that a possible discovery of a signal may potentially falsify QGD. Far from it!

Yesterday I explained that, in itself, a signal resembling gravitational waves is not enough to establish their existence. A tidal force effect from a binary system can produce the same signal. I also explained that if such a signal were caused by gravitational waves from a binary system that it must be in perfect synch with electromagnetic signals for the same system. If gravitational and electromagnetic signals are in sync then, yes, the gravitational signal must be caused by gravitational waves and general relativity’s prediction is supported. However, if it is in sync then gravitational waves are not the cause and QGD’s prediction is supported.

If they did detect a gravitational signal, having only two detectors, it will be impossible to pinpoint the location of the source, but when a third detector is added, we’ll be able to find the location of sources of gravitational signals. When we do, there will be two possibilities.

1. Radio signals from a system that caused the signal will stop since it merged into a single object. This supports general relativity.

2. Radio telescopes continue to receive signals from a system and will be doing so millions of years. This is QGD’s prediction.

QGD also makes other predictions with sets it apart from those of general relativity.

For one, from QGD’s equation for gravitational interaction, we know that the magnitude of gravitational interaction between two bodies decreases in a way that is in agreement with Newton’s law of gravity and does so until it reaches a threshold distance of around 10 Mpc at which distance it equals to zero. So binary systems located at the threshold distance from us would have no detectable gravitational effect. But beyond the threshold distance, the gravitational interaction becomes repulsive and increases exponentially to the square of the distance. Basically, a gravitational interaction signal from a binary system at a distance of 30 Mpc would four times greater than the signal from a comparable system at 20 Mpc. Such a signal would be much stronger than the signal predicted by general relativity. At 30 Mpc, it would four times greater and nine times greater at 40 Mpc. So if QGD is correct, beyond the 10 Mpc, the greater the distance of a binary system, the greater the gravitational signals.

Also from the QGD equation for gravity, we find that the effect of gravity beyond the threshold distance is the same as the effect we know as dark energy. As a consequence, the strength of a gravitational signal from a binary system must be exactly proportional to the acceleration of the system relative to us.

However this turns out, if a gravitational signal has been detected, it will be the basis of a huge leap in our understanding of the universe.
