Boson clouds … the latest glittering dark matter related gnome … which they claim gravitational detectors will be able to detect.Could gravitational waves help us find dark matter?
Astronomers use super-sensitive instruments to look for boson clouds, a leading contender for dark matter.
But then I remembered that they have to have some new wild eyed theory to justify the more than one BILLION dollars that they’ve already spent on LIGO, the $200 million+ spent on Japan’s KAGRA detector so far, the unknown cost of Europe's Virgo detector (in Italy) (unknown because they seem particularly reticent to publish ANY cost numbers. But, from the looks of it, it’s probably at least several hundred million dollars), the $177 million estimated for India’s LIGO, plus what’s projected for improvements to each of those detectors (hundreds of millions of dollars, in some cases), plus what's projected for NEW gravitational wave detectors (at a billion plus dollars each), such as the 3rd generation (3G) gravitational network, the Einstein Telescope (actually, $2 billion for this one), a US gravitational wave space antenna (LAGRANGE?), a European Space Based GW Observatory (LISA?), plus any number of other toys that they’ll dream up and insist are essential to detect gravity waves. And all that’s not even counting what China, Russia and the rest of the world are spending on this stuff. With all that, maybe they will find boson clouds. Or claim they have, invoking some additional gnome.
