Next-Generation Dark Matter Detectors Will Study The Universe Like Never Before

Bigger doesn’t always mean better but certain physics detectors could be the exception that confirms the rule. Especially if the goal is to detect elusive particles such as neutrinos or hypothetical particles such as dark matter. To that end, there have been some recent exciting developments.

And you can bet they involve lots of money, because that another thing where bigger is better as far as mainstream astrophysicists are concerned is how much the detector costs. It's money in their pocket. And what do they have in store for everyone in their gnome hunt? Well read on ...

The DARWIN and LUX-ZEPLIN collaborations, which run the biggest experiments focusing on discovering dark matter, have just announced they have united to build a new, GIANT next-generation detector.

And here is their announcement …

https://www.sanfordlab.org/press-releas ... r-detector

The current xenon-based experiments XENONnT and LUX-ZEPLIN will start their first science runs in 2021, to lead the race to detect the first signs of new particles and interactions. These experiments employ 5.9 and 7.0 tonnes of liquid xenon for the search, respectively.

… snip …

The new multi-tonne liquid xenon detector will combine the most successful technologies employed in rare-event searches with xenon detectors, including those developed for XENONnT and LUX-ZEPLIN, and from targeted R&D including that supported under DARWIN.

So … they haven’t even got results back from their last set of expensive, multi-million dollar detectors and already their eyes are moving on to the next one. Here’s what Luca Grandi, Primary Investigator of the XENON/DARWIN projects says about it … “It is an exciting period for us with both XENONnT and LZ expected to release first data by the end of the year. A larger detector will be essential in both scenarios that we have in front of us. If we see a hint of dark matter in our current experiments it will be needed to further characterize its origin. If we do not, it will allow to continue to explore new territory where dark matter might still be hiding.” Richard Gaitskell, another member of the LUX-ZEPLIN team says “If we see a dark matter signal using our 10-ton detectors, we will then need a much larger detector to accurately determine the properties of that elusive dark matter. … If we see nothing over the next few years with the 10-ton detectors, we will need the much larger detector to probe additional hiding places of the dark matter. The work on the research and design for the new even more massive next-generation detector has begun.”

How exciting! And they clearly have all their bases covered, don’t they? They plan on getting their new, GIANT detector no matter what happens? Not clear if it’s going to be called DARWIN still ... or something else. But in any case, it’s going to be “multi-tonne”. That’s pretty vague. What aren’t they telling folks? The cost, perhaps? Remember that Darwin was supposed to have 50 tonnes of xenon … just about the world’s annual production of the stuff … and cost between $116 million and $174 million. Are they planning something now that’s even bigger than that and just not saying it? They know how the public loves surprises. Only time will tell. But the beauty of their scheme is that when Darwin or whatever the next generation GIANT detector is called fails to find anything (as I predict), they can still come back and justify an even GIANTER detector using the same logic. Isn't mainstream *science* fun? Just saying …

In no other area of science would it be considered "scientific" to engage in such blatant confirmation bias. Never is any so called "test" of dark matter used to falsify the basic concept of exotic forms of matter. At most, those "tests" only serve to "constrain" the stuff into ever shrinking gaps of energy states. It's just pathetic at this point.

They've essentially ruled out all the higher energy ranges accessible to LHC and beyond, and down to the energy level of neutrinos. It's now just a funding game to keep the money rolling in, and there is no attempt at all to falsify the whole concept of exotic forms of matter. I'd say part of the reasoning for *not* trying to falsify the existence of exotic matter is due to the need for particle physicists to justify their desire for a bigger, next generation collider. Both particle physicists and astronomers have a vested emotional and financial interest in keeping exotic matter models alive.

Actually, there is one other area, Michael ... climatology ... specifically by the proponents of CO2 induced global warming/climate change. I can prove with just two charts of data that the mainstream has had in their possession for decades that the idea that CO2 is going to lead to a climate catastrophe is hogwash. But they consistently ignore any discussion of that. And, as in the case of dark matter, there apparently is no test that will falsify their claim in their minds.

Yep.

Speaking of failure to find dark matter …

Searching for Dark Matter Inside the Earth

Dark matter remains one of the greatest mysteries in science.  Despite decades of astronomical evidence for its existence, no one has yet been able to find any sign of it closer to home.  There have been dozens of efforts to do so, and one of the most prominent just hit a milestone – the release and analysis of 8 years of data.  The IceCube Neutrino Observatory will soon be releasing results from those 8 years …

… snip …

Based at the geographic South Pole, IceCube consists of 86 strings of digital optical modules containing 5160 individual optical sensors that will detect a type of light created by Cherenkov radiation when any neutrino interacts with another particle.  By triangulating the brightness and longevity of the light pulse, scientists can then backtrack the speed and direction that the neutrino was traveling.

Given the finicky nature of the equipment and its particle of interest, noise reduction is a key component of IceCube.  Part of that strategy is done via isolation – not only is the detection array based at one of the most isolated spots on Earth, it also is buried under 1450m of ice and spans almost a vertical kilometer in depth. 

 

You know what this detector cost? $279 MILLION dollars. And what did they find? NOTHING. They found no evidence of dark matter … no unusual excesses of neutrinos coming from the Milky Way core. But mainstream astrophysicists are not giving up. Oh no … they want to keep the money flowing in. They plan to keep on taking data for years with the HOPE that it will show something. AND they have plans for an even bigger detector … https://icecube.wisc.edu/science/beyond/ “Beyond IceCube”. Projected Cost? About $350 MILLION. Tens of million have already been funded. By gods, they are going to find dark matter if it bankrupts us!

When you understand quantum dynamics of Chiral Supersymmetry and the resultant Dipolar electromagnetic condensate vector fields as vortices (jets) expelled from the condensate and the resultant vector fields that pull matter into the condensate, you will understand that Dark Matter and Dark energy are terms used by people who cannot explain observations.
Than they use terms like Missing Matter etc.

Dark matter hunt gets hotter with first derive from worlds biggest detector

This is on the USA Today website, a major mainstream media outlet. A title like that (and frankly the whole article is just chuck full of poor grammar, bad sentence construction and misspelling) makes me wonder if the editors of USA Today are even educated or exercise ANY control over the content they publish. It's a sign of the times I guess ... and why I'm so down on the future.

And now the good ... no, wait! ... bad news ...

Physicists dealing with the worlds biggest dark-matter detectora behemoth in the usa referred to as LUX-ZEPLIN (LZ)released their first results today. They see no sign of what theyre looking for, so-called weakly interacting massive particles or WIMPs.

If you can get past all the bad english in that, you'll see the author said the first results from the experiment failed to find any Dark Matter. But "the null result still has value". In other words, keep sending mainstream astrophysicists money.

By the way, the article is republished from Science.org ... https://www.science.org/content/article ... t-detector ... which does NOT have the English mistakes. So, how did USA Today's version get so bad? Was there even one human being involved in the process? Ironically, when I visit the article on science.org, a popup appears saying "Support nonprofit science journalism". You have to laugh at that in this context.
