And no coincident neutrinos were detected by either Antares (the neutrino detector, not the rocket ) or ICECube:https://dcc.ligo.org/public/0123/P1500271/013/GW150914_neutrino.pdf (paper)http://icecube.wisc.edu/news/view/398PS: I just saw the same links posted in the "Space Science" subforum thread. I will keep these here, but if they are merged my posts are redundant since I wrote them several hours after the other guys'. Moderators please delete this and the previous post if you're merging the treads.
Guess the communication satellite days are numbered.

It's irrelevant to his point.His point is that the LIGO data simply confirms the most widely held theories, so it in of itself simply rules out some of the more esoteric theories and doesn't do much to lead us to new ground.New experimental results that are a surprise are much more useful to get us to understand things we didn't understand before. The LIGO results aren't a surprise. They're the opposite. We turned over another rock and found exactly what we expected. We'll keep turning over rocks, looking for surprises, and the LIGO hardware might yet help us find surprises under different rocks, but so far, no surprises, and no help toward new physics.
You could get a gamma-ray burst if the two black holes were enveloped inside a very massive star. “It’s sort of like a pregnant woman with twins in her belly,” Once the black holes merged, the star would collapse and trigger intense beams of gamma rays. For that to happen, the two black holes would have to have formed inside an extremely massive star a few hundred times heftier than the sun. As the star exhausted its nuclear fuel, its core began to collapse. Normally that would form a single black hole. But if the star were rotating very fast, centrifugal force would stretch the collapsing core, shaping it into a dumbbell. Eventually, the dumbbell would snap into two cores, each of which would continue to collapse into its own black hole. "The only way to explain the Fermi signal is to surround the black holes with a lot of dense material"
excuse my ignorance but isn't this a confirmation for space time warp in macro scale(instead of micro) for which dr. white was looking for in egale works for warp drive potential or is it different kind of warp of space time?is it a little step forward or no relevance at all?The metric derived by Alcubierre was mathematically motivated by cosmological inflationso this would by much more solid proof of concept if i understand it correctly of course it doesn't give an answer if we could induce such a warp artificiallystill dark matter /dark energy is just a hypothesis
Didn't i read an article a while back that suggested an advanced gravity wave detector could be made to fit on a desktop?
Given that even planets orbiting stars produce Gravitational Waves, I'm wondering whether Gravitational Astronomy might one day be able to detect them.

Those were bitter political times, Lane said. After all, the Republican Congress would move to impeach Bill Clinton in a few years. But there were still Republicans and Democrats working across party lines on the appropriations process. Work was going on, staff to staff, principal to principal. Today, Lane doesn’t see that kind of cooperation, and it spells major trouble for any new programs a president might seek to fund, like construction of LIGO instruments.“Never say never,” he said. “We should always hope, always try. I would just say the conditions are very different. Polarization is one thing. The other thing is the private sector some time ago—but even government now—is moving steadily toward short-term deliverables for everything. Expectations are not patient. If the President’s Office of Management and Budget sent this over today, I think you’d have a very hard time getting it through Congress.”Lane is probably correct. On the very same day that physicists announced their spectacular findings in early February, the US House of Representatives passed legislation sponsored by Texas Republican Lamar Smith, HR3293, that allows the NSF to award grants only for research it can certify as being in the national interest, such as benefiting the economy or improving national defense.“It really is an irony,” Lane said of the timing. A bitter one.
