More money wasted and more disappointments on the way. This observatory is supposed to detect gravitational waves by measuring minute fluctuations in laser beams shooting over long distances. The gravitational waves are said to be ripples in the fabric of space-time, however, modern physics denies that space-time has structure that can ripple. If it did, it would fit the description of the Aether, which mainstream academia emphatically denies.
The interferometer won't work because the space the laser beam is moving through, as well as the laser beam, will both ripple at the same time. It is like trying to knock a cowboy off his horse in a movie shown on a flexible screen TV by flexing the screen.
In order to detect gravitational waves, the detector has to be a large magnetic field with magnetic flux lines stressed to the breaking point. When a gravitational wave comes through, it would break the magnetic flux lines. The more flux lines broken, the more intense the gravitational wave.
Magnetic fields can detect gravitational waves because they actually exist in a five dimensional space-resonance coordinate system, which is the true coordinate system of the "fabric of space-time." Space-time is a subset of space-resonance and only has four dimensions.
Physical matter exists in space-time, but not in space-resonance. Only photons and magnetic fields exist in all five dimensions, which are length cubed by frequency squared (resonance). Similarly, a movie exists in area-time while the audience exists in space-time. If someone existing in area-time tried to build an interferometer, it could never reach out to detect space-time any more than an interferometer in space-time can detect movement in space-resonance.
The incredibly redundant article below appears to be nothing more than a press release explaining why millions of dollars was spent. The science is worthless.
