Dark matter definitely does not consist of weakly interacting particles (wimps)

XENON’s experimental triumph: No dark matter, but the best “null result” in history

"Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary ...

The true beauty of the XENON experiment is that it is, by design, scalable. With each successive iteration of the XENON experiment, they’ve increased the amount of xenon present in the detector, which in turn increases the sensitivity of the experiment to any interaction that may be present between dark matter and normal matter. If even 1-in-100,000,000,000,000,000,000 xenon atoms would have gotten struck by a dark matter particle over the course of a year, resulting in an exchange of energy and momentum, this setup would be able to detect it.

Over time, the XENON collaboration has gone from kilograms to hundreds of kilograms to a tonne to now 5.9 tonnes of liquid xenon as their “target” in the experiment ..."

So they're hard b*st*rds, these dark matter types?
But (I think) the article misleads by saying dark matter has been disproved. Although wimps are/were the most popular candidate, there are other possible dark matter particle candidates such as axions that the xenon device would not detect.
