Initial Tests Fail To Find Gravitational Waves

eldavojohn writes that though gravitational waves are "predicted to exist by Einstein's Theory of General Relativity, the initial tests run by the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO) failed to find anything. It doesn't disprove their existence although it does rule out a subset of string theory. From the article, 'For example, some models predict the existence of cosmic strings, which are loops in space-time that may have formed in the early universe and gotten stretched to large scales along with the expansion of the universe. These objects are thought to produce bursts of gravitational waves as they oscillate. Since no large-amplitude gravitational waves were found, cosmic strings, if they exist at all, must be smaller than some models predict.' The scientists working in Washington and Louisiana (in tandem to rule out flukes) will now move on to Advanced LIGO which will analyze a volume of space 1,000 times larger. If they don't find any gravitational waves in that experiment, the results will be more than unsettling to many theorists."

      Yeah, they turned it off and back on, but they forgot to blow out the cartridge! It's like they just don't know how these things work, didn't they learn ANYTHING in college?

    This is obviously because gravity does not exist, but the observed effect is a result of an higher intelligence pushing things down.

    I like to see string theory crumbling as much as the next man, but err.. that :

    dark matter can be explained by the evolution of advanced technological civilizations based on *known* physics (through molecular nanotechnology and extreme engineering)

    If given the choice between these two propositions, I think I'll stick with string theory and its 26+ space dimensions. But kudos to you for pioneering a new approach to astrophysics that consists in claiming "space aliens did it".
