Scientists detect the most compelling indication of dark matter to date
Researchers at the LUX-ZEPLIN experiment in South Dakota announced on September 1 the detection of a particle interaction that may involve a WIMP (weakly interacting massive particle), a leading dark matter candidate. While the interaction exhibited properties consistent with dark matter behavior, scientists emphasized the observation does not yet meet the statistical threshold for a confirmed discovery and represents only a single event requiring further validation.

I'm not suggesting distortion or misrepresentation of the published result. The actual preprint is quite clear on the nature and limitations of the result, and there's no reason to think that what they're reporting didn't happen as described.However, the context here is that the DOE has already paused funding for the experiment's successor, XLZD…

> It's an open question, right, whether dark matter has no interaction or just very little interaction with normal matter? If there's none, this experiment will detect nothing but noise.Correct. What this experiment (LUX-ZEPLIN) is looking for is the effects of xenon nuclei being "bumped" - recoiling - due to something undetectable. It doesn't…

Particle physics is not a particularly large community. There is a hand-countable number of experiments like this, and the folks working on each of them know the folks working on each of the others. The collaborations executing each experiment are comprised of scientists employed by multiple independent institutions, both public and private…

To expand a little, my prediction is based on the fact that we can already explain the vast majority of physical processes with extreme procession. The things we can't explain tend to be very small, very large or very quick. But there's almost nothing in our day to day lives that we can't explain anymore.This means that today to make new…

Makes sense, but is it relevant to the upthread claim that "All provable models (theories, explanations) that we have, or could have, are by definition wrong or incomplete"? (Not being rhetorical and snide here, I'm curious and aware I may be missing something.)If reality has irreducible randomness (an open question afaik), and we're talking about…

> I just can't believe something like dark matter exists.That's a lot like a blind person saying they can't believe light exists.It takes only a small amount of knowledge of physics to understand why and how dark matter might be possible, even likely. So small, in fact, that I can describe it in this comment.The tl;dr is that all the senses you…

> No idea what equations are used for getting to the result"Basic" gravitational equations applied to observed behaviour: clumping and rotation of galaxies, lensing (light bending), etc.The behaviour implies "something" is exerting force in a mass like way - but there's a shortfall of visible mass.The observational hole left by the apparent…

This raises what is (I think) an interesting question. CERN is a collider, so they are _trying_ to produce lots of stuff, and they do (lots and lots of stuff). They can't write it all to disk, and most of it isn't interesting enough to try.The work being done here falls into the category of "low background physics" --- they aren't trying to…

The possible dark matter interaction seen in the LUX-ZEPLIN detector is intriguing, but it's far from a definitive detection. Of course it is exciting that we may finally have a non-gravitational signal of dark (better invisible) matter, but best not to get too carried away just yet..... https://www. nature.com/articles/d41586-026 -01985-9 #…

Scientists have made a possible breakthrough in the hunt for dark matter — during an experiment deep underground in South Dakota — but stopped short of saying they finally detected the elusive cosmic component. https://www. japantimes.co.jp/news/2026/09/ 02/world/scientists-breakthrough-search-dark-matter/?utm_medium=Social&utm_source=mastodon #…

Doesn't that just mean that our models and expectations might be wrong? They might very well be. As they've been many times before. I mean, we got stuff like the cosmological principle which were based on the lack of observations. Hubble and JWST has knocked some massive holes in that theory but still it isn't discarded (the inventors of the…

For the moment, nothing. Galaxies act through gravity like they are about 6 times heavier than the light from stars and such can account for. Since the missing 5/6ths doesn't produce light, it got labeled "dark matter". Since the 1970's or so, scientists have been trying to figure out what dark matter is made of. "Weakly interacting massive…

This is a fun question! These detectors are incredibly complicated one-of-one machines with thousands of sensors. The detector needs to be monitored around the clock to make sure nothing has become unstable. The system itself is not just a sealed vat of xenon; all 10 tons of xenon in it need to be recirculated by large circulation pumps which also…

Have physicists detected their first dark-matter particle after decades of searching? It's way too early to make that claim, but an anomalous event recorded at an underground lab in South Dakota has definitely captured the attention of dark-matter detectives. https:// cosmiclog.com/2026/09/01/scien…

Here's the Bullet Cluster . It's two galaxies that had a head-on collision. Look at the pictures in that article. In this one , the red/pink is normal matter (the visible stuff) that is glowing in X-rays because of all the collisions and compression from the galaxies colliding. The blue is calculating where the mass is located based on the…

Yes we have actually, the Bullet Cluster is the premium example of this https://en.wikipedia.org/wiki/Bullet_Cluster The major components of the cluster pair—stars, gas and the putative dark matter—behave differently during collision, allowing them to be studied separately. The stars of the galaxies, observable in visible light, were not greatly…

The Physic world is abuzz with news of a particle interaction detected by the world’s biggest dark matter detector - LUX-ZEPLIN (LZ) - that is difficult to explain with known background processes. Is it evidence of WIMP, the mysterious Weakly Interacting Massive Particle? WIMP mass = 200x that of a proton. This is a 2.6 sigma significant event -…

I believe you're describing a subfield of a theory known as a "holographic universe". My professor made some contributions to the field! We describe a braneworld description of cosmology with both 4d induced and 5d bulk gravity (otherwise known as Dvali-Gabadadze-Porati, or DGP model), which exhibits this feature: The universe emerges as a…

Weakly interacting doesn't mean non-interacting. It just means it reacts with gravity and some other weak force, which could be the weak-nuclear force (as is the case with neutrinos) or perhaps a force which is currently unknown (to be expected if its a very weak force). And, actually, the most important aspect of dark matter interactions is that…

No, the point is that if you measure gravity at Earth and extrapolate to galaxies, ot doesn't work with the visible matter. There is no darl matter component to Earth, because the (presumed) dark matter is.moreorless evenly spread in galaxies. If there was dark matter in everything, we would just now it as "normal gravity" and wouldn't see a…
