Edging Closer To Finding DM

But, the first line of the article says …
The article goes on to say that the LUX-ZEPLIN Dark Matter Experiment (LZ), based at the Sanford Underground Research Facility in South Dakota is “nearly five times more sensitive than previous investigations and indicate WIMPs seldom interact with ordinary matter, confirming just how difficult dark matter is to trace.” Or confirming that it isn’t there at all.
It then quotes Henning Flaecher, Professor of Physics and Principal Investigator of the Bristol group, saying, "The results present a significant improvement over previous searches for WIMP dark matter. We have probed a large range of masses that dark matter could have and its interaction strength with normal matter but so far it remains elusive.”
So yes, they didn’t find any evidence of DM but that’s still good news for astrophysicists because they’ll all be employed a lot longer … AT YOUR EXPENSE … looking for it.
The New Scientist article about this is a letter closer to the truth …

Isn’t that another way of saying the new research didn’t find it?Pioneering research suggests nature of dark matter is more elusive than ever

How does not finding something edge one closer to finding it?New results from the world's most sensitive dark matter detector narrow down its characteristics, edging closer to unraveling one of the biggest mysteries of the universe.

Then but it says ...Another blow for dark matter as biggest hunt yet finds nothing
Notice that the search gets progressively more expensive and the only people who benefit are the swimmers. The rest of us stay on shore and work our butts off to pay for their swims and equipment. And note ... none of them have yet detailed a benefit we'll get if they do manage to actually find DM.While this result may seem like a disappointment, it has allowed physicists to place tight constraints on the nature of dark matter, reducing the range of properties it could have. … snip … “It’s as if we’ve been told there’s some magical fish that lives in the ocean and we have no idea where it is,” says Ghag. “We get into the ocean, swim around, get out, get a snorkel, swim around, still don’t find it, get a submarine.”
