Astronomers think there should be 5 times as much dark matter as ordinary matter - a shadow universe that makes up most of the mass in the universe. But after decades of trying, no experiments have found any trace of dark matter - except one.

But that's super rare, so it's really only used in the CUORE experiment for some of the shielding, and for soldering stuff in some specialized applications, such as in CRESST. Old iron is too brittle. And copper can be made extremely clean using electrolysis (and even cleaner doing the electrolysis underground)

Since we already know of particles that don’t interact with some of the fundamental forces, it makes more sense to me that there’s a particle that simply only interacts with gravity. Like, neutrinos only interact via the weak force and gravity, but we already know a lot about them; I doubt dark matter, if it interacted with either of the nuclear forces, could be so elusive.

But think about if a particle doesn’t interact with anything then it’s literally impossible to detect. If dark matter *only* interacts with gravity but on a minuscule level, then it’s going be incredibly difficult to detect on a small level. We’re only seeing the affects of dark matter on a astronomical level. Meaning it takes a ton of dark matter over a massive area to affect anything.

They only started data collection in early 2023, so it's probably going to be a while before results are published. Moreover there are other experiments trying to replicate the DAMA/LIBRA results, and one from south korea (COSINE-100) managed to "in a way" replicate the results. I put this in quotation marks because with their initial data analysis method they got a null result (aka: they found no signal whatsoever) but then they took their data and analyzed it with the somewhat particular data analysis method DAMA/LIBRA used in their publications and "found" a signal as well. Problem: This COSINE-100 signal is almost the inverse (the phase is flipped) of the original DAMA/LIBRA signal, so this is no good news for the dark matter theory as it might be some other effect. Or even worse, the signal might have been induced by the data analysis method itself and be completely arbitrary (low frequency noise generated by the photo multiplier tubes that is not modeled/compensated correctly). For more info just google "An induced annual modulation signature in COSINE-100 data by DAMA/LIBRA’s analysis method", the paper is freely available, short, and the non technical part relatively easy to understand

I'm a PhD candidate working on DM and I think this video was great. I see so much discussion online where people assume scientists are just being narcissistic when we assume DM exists and that it must be like the new version of luminiferous ether theory, because they're not in tune with just *how much* **independent** evidence we have that is cleanly explained by particle DM. My only gripe with the entire video would be that I wish you had mentioned specifically that the idea of a particle "we can't see" or being "dark" isn't absurd in the slightest--I think part of why laypeople have gripes with the idea is that they think it's absurd that we could just posit something "invisible" is there. In reality, we already know of MANY particles that are similarly "invisible"--like neutrinos! In this context, "invisible" just means "doesn't interact with light" which is precisely true of neutrinos, and yet we are bombarded with trillions upon trillions of solar neutrinos every second from the sun. Unfortunately, we are not so lucky that DM is as easy to detect as neutrinos :)

Look I’m suspicious of dark matter theory because, if you’re going to try and invent an entire new class of particles that supposedly only interacts with matter/light through gravitational force alone, but there’s zero and I mean ZERO evidence that these supposed particles exist……… COULD (particle) dark matter theory turn out to be correct? Absolutely, yes, but forgive me for being suspicious of a theory that frankly has zero evidence in support of it We KNOW beyond reasonable doubt that there’s plenty of mass unaccounted for in our universe, this is true, and I also am suspicious as hell of MOND because (just like particle dark matter theory) it’s an ad hoc explanation with no real evidence to support its validity…… My basic point is this: Don’t think that the ‘opposition’ to dark matter theory is because it’s weird and people can’t ‘see it’ because quantum mechanics is absolutely weird as hell, but it’s true it gives very precise predictions and is verifiable and testable through endless experiments It is frankly unscientific at the core, to believe in particle dark matter theory as anything more than a POSSIBILITY, unless and until there is evidence for it We’ve spent years and billions of dollars building dark matter detectors and as of yet, nothing……… Again I’m not saying (particle) dark matter isn’t real, and it MIGHT be the best explanation we’ve so far come up with, but unless and until there’s actual evidence for it…….

The Alps are located in the northern Italy going from est to west, the Appennini divides Italy in two going from north to south (starting roughly at the border of tuscany and emilia-romagna and ending with the Etna). The lab where the Dama/Libra is locates is called INFS (istituto nazionale fisica nucleare) and they also tested neutrinos’ speed with the CERN in Ginevra.

@aracdestroyerofworlds Рік тому
Okay so exposition time from someone who's currently working on dark matter densities. If dark matter does interact with itself, then yes there would be the dark matter equivalent of friction and dark matter would slowly migrate to already dense places in the Universe. This is because friction is the result of particles colliding/interacting and re-distributing their energies, and changing the energy of a particle alters its trajectory. However, we have no evidence (that is significant and that I know of) for this dark matter self-interaction. Think back to the Bullet cluster example. If the dark matter did self-interact significantly, it would have behaved more like the ordinary matter; colliding and getting stuck in the middle. This didn't happen, and instead the dark matter clouds passed through each other completely unfazed. No significant self-interaction means no way of re-distributing energy, and thus dark matter particles don't alter their trajectories once they're on a set path. This means that the only dark matter particles that would end up in singularities, are the ones that were already going to collide with one head-on, and the radius of no escape from a heavy object is very small compared to the rest of the Universe. So yeah, that's why we have dark matter zipping around all over the place.

What might additionally be interesting to know is, that there are already two experiments currently running, which try to independently find the same signal as DAMA/LIBRA, named Cosine100 and ANAIS. Both have around three years of measuring time and are starting to become able to judge if the DAMA/LIBRA signal can be reproduced. So far the results of ANAIS seem to indicate no signal can be found, while Cosine is not yet able to make a clear statement, since the bestvalues for certain interesting parameters lie inbetween the zero hypothesis (there is no signal) and the DAMA/LIBRA finding. So right now the trend is leans towards the signal not being due to dark matter, but only time and more experiments will tell, if this ts the case.

@@bogbutter In my humble opinion, science started with the telescope/microscope for a reason. What you can't see (well) you can't test (well), and what you can't test is not science. Statistics aren't all powerful and won't fix a blurry image (it's not possible to zoom in the pixels of an image like in a movie), what they may actually do is create fake information (see ML up-scaling). So in conclusion, anything too big to see properly in detail (such as galaxies) or too small (such as the quantum world) is not science, and will not be science until we figure a way to see properly (one that doesn't rely on statistics). Until then we may have theories, but those ain't better than the theories we did in the past about the earth being flat. Instead of focusing on making theories and more theories, we should focus on making machines too see properly.

"Commendation from NASA for research work at Massachusetts Institute of Technology on the Earth's atmosphere and the Moon's surface for navigation of the Apollo spacecraft to the Moon.. Dr. Milo Wolff has found the structure of the electron consisting of two spherical quantum waves, one moving radially outward and another moving radially inward. The center of the waves is the nominal location of the electron 'particle'. These waves extend infinitely, like charge force. All 'particle' waves mix and contribute to each other, thus all matter of the universe is interrelated by this intimate connection between the fundamental 'particles' and the universe. The natural laws are a direct consequence of this Wave Structure of Matter (WSM), thus WSM underlies all of science." "Mathematics has the completely false reputation of yielding infallible conclusions. Its infallibility is nothing but identity. Two times two is not four, but it is just two times two, and that is what we call four for short. But four is nothing new at all. And thus it goes on and on in its conclusions, except that in the higher formulas the identity fades out of sight."

@echo.1209 Рік тому
Same. I'm more wont to believe that our understanding of gravity is wrong rather than the existence of a large amount of invisible matter, but the explanation shows that there's more to it than just "our data is not lining up with our theories". I guess the thousands of intelligent physicists around the globe who know much more about this topic than any of us would have thrown away the dark matter hypothesis if there were no such convincing evidence.
@Greippi10 Рік тому
@@Cuestrupaster Yes but the thing is, like Echo.120 expands below, is that with what evidence we do have it seems to be much less likely that our theories have a fundamental issue with them. This thing always pops up in the comments on videos about dark matter, hence why I made the comment in the first place. And I do understanding why it's appealing to think that it must be the theories that are wrong, since we have no direct detection after 90 years of having seen the effect. The human mind likes pattern detection, and for the layman it seems like there is no pattern. But the scientific consensus on the matter has been formed by people who have spent *literal lifetimes* studying the topic. And the evidence they've found points towards dark matter being real, whereas the other other option has way less evidence. So surely it makes sense to pursue the one that has some merit to it, instead of going on a wild goose chase just because we've found nothing so far?

Plus, there are multiple other reasons to look at our theory of gravity from dark energy to disrepency with quantum mechanics anyway.

"History abundantly shows that people's views of the universe are bound up with their views of themselves and of their society. The debate in cosmology has implications far beyond the realm of science, for it is a question of how truth is known. How these questions are answered will shape not only the history of science, but the history of humanity." (Eric Lerner, 1992) One of the main reasons 'big bang' is pushed so ferociously is that it has been endorsed by the vatican.. "In fact, it seems that present-day science, with one sweeping step back across millions of centuries, has succeeded in bearing witness to that primordial 'Fiat lux' (Let there be light) uttered at the moment when, along with matter, there burst forth from nothing a sea of light and radiation, while the particles of the chemical elements split and formed into millions of galaxies ... Hence, creation took place in time, therefore, there is a Creator, God exists!" (Pope Pius XII, 1951) 300 years before this, 'the church' had Giordano Bruno publicly murdered for saying that space is infinite.. You 'do the math'.. NO! Please don't! This is why the erroneous ideas of 'infinity' are used in mathematics, specifically to confuse people into a misunderstanding of what infinitude actually means..

Love the vid. Derek Muller's final question is funny: "Do you think that dark matter interacts with ordinary matter?" The reasons scientists have posited the existence of dark matter is that ordinary GR gravity/curved space-time is inadequate to explain some observed phenomena, such as the speed of stars at the outer ends of galaxies. "Dark matter' is shorthand for saying 'there must be some other matter that we can't see out there that's interacting with ordinary matter.'
