Last Chance For Wimps: Physicists Launch All-Out Hunt For Dark-Matter Candidate:
Physicists have long predicted that an invisible substance, which has mass but doesn’t interact with light, permeates the Universe. The gravitational effects of dark matter would explain why rotating galaxies don’t tear themselves apart, and the uneven pattern seen in the microwave ‘afterglow’ of the early Universe. WIMPs [weakly interacting massive particles] became a favourite candidate for the dark matter in the 1980s. They are typically predicted to be 1–1,000 times heavier than protons and to interact with matter only feebly — through the weak nuclear force, which is responsible for radioactive decay, or something even weaker.
Over the coming months, operations will begin at three existing underground detectors — in the United States, Italy and China — that search for dark-matter particles by looking for interactions in supercooled vats of xenon. Using a method honed over more than a decade, these detectors will watch for telltale flashes of light when the nuclei recoil from their interaction with dark-matter particles.
Physicists hope that these experiments — or rival WIMP detectors that use materials such as germanium and argon — will make the first direct detection of dark matter. But if this doesn’t happen, xenon researchers are already designing their ultimate WIMP detectors. These experiments would probably be the last generation of their kind because they would be so sensitive that they would reach the ‘neutrino floor’ — a natural limit beyond which dark matter would interact so little with xenon nuclei that its detection would be clouded by neutrinos, which barely interact with matter but rain down on Earth in their trillions every second. “It would be sort of crazy not to cover this gap,” says Laura Baudis, a physicist at the University of Zurich in Switzerland. “Future generations may ask us, why didn’t you do this?”
The most advanced of these efforts is a planned experiment called DARWIN. The detector, estimated to cost between €100-million (US$116-million) and €150 million, is being developed by the international XENON collaboration, which runs one of the 3 experiments starting up this year — a 6-tonne detector called XENONnT at the Gran Sasso National Laboratory near Rome. DARWIN would contain almost ten times this volume of xenon. Members of the collaboration have grants from several funding agencies to develop detector technology, including precise detection techniques that will work over DARWIN’s much larger scales, says Baudis, a leading member of XENON and co-spokesperson for DARWIN.

Replace "dark matter" with "ether," it's the same old shit.
But, oh well, gotta try whatever when there is nothing better.
Who knows - maybe one day "ethernet" will be replaced by "fantasynet."
Personally, "anthropic principle" is the worst transgression in physics, in 20th Century no less. Why not go back shamanism. And these clowns are "distinguished" professors at Stanford, Columbia, Harvard, Princeton, etc.
No wonder Novel prize was given out to old geezers studying blackholes for decades.

Exactly.
Because observation bias doesn't exist in physics, right? What would be a worse transgression is to ignore the anthropic principle.

The anthropic principle says that this universe is one in which humans evolved. An observation. An experimental fact.

and the cool part is that everybody in their back yard can go confirm them results ...
lots of trust involved.
the benefit being obviously that the last "crack" in a complete and total system of universal understanding can be filled out leaving

also here is a ratio and a recipe that is more usefull to know that the answer to the question "what is the capital of switzerland":
when making concrete be sure to add the same amount "volume" of cement powder (run-of-the-mill, nothing fancy, burned limestone +-) and water.
mix water volume 1 and cement volume 1 together FIRST. no cement clumps allowed. add sand and stones as needed mostly 4 volume sand and 4-5 volume stones. so 1:1:4:5 (or as finances allow, cement being the most expensive ingredient).
when pouring concrete the container will give the shape (duh) and make it so that it could hold water without leaking!
also to get a right-angle take a string of length A (notice, no centimeter, or inches or kilometers here) and extend it to sections of 3A:4A:5A. when you now make a triangle with sides of length 3A and 4A and 5A you will get ONE right-angle. NOTE! the UNIT 1 (one) or A can be ANY length so you don't need to have/buy a measuring tape at all.

well oops sorry. that there is some bullcrap.
the ratio is 1:1:2:3 for water:cement:sand:stone.
if you got a "vibrator" you can try and fit in more stones for a volumn ratio of 1water:1cement:2sand:4stones.
i still recommend measuring water and cement volumn and mixing it first. the volumn measuring "device" can be a thimble, yoghurt cup and a standardize oil-barrel. just keep the same bucket for one batch ...
