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.
A massive thanks to the wonderful people at the ARC Centre of Excellence for Dark Matter Physics https://www.centredarkmatter.org for showing us around and being on camera – Fleur Morrison, A/Prof Phillip Urquijo, Prof Elisabetta Barberio, Madeleine Zurowski and Grace Lawrence.

Alps? It is not located under Alps. It is near to Rome.
@griefer081 Says:
maybe it is just gravitons being crazy
@griefer081 Says:
We overexplored science too much, how do we even learned a lot of this
@griefer081 Says:
Imagine if dark matter is just dust
@drbestplus Says:
The black hole at the center of the galaxy has drawn so many stars into a tighter orbit around it that a large portion of the gas and stars in the center are arranged around the black hole—something that is actually visible in any image of our galaxy.
@MicheleQuaglia-m9d Says:
Little typo at the beginning of the video: actually the Gran Sasso mount is part of Apennines mountains, not Alps
@happyandhealthy888 Says:
is Earth to dark?
@lavlav2340 Says:
Thumbnail goes hard
@BrazilGod2808 Says:
Pretty sad they can’t find Dust
@dongchulgold Says:
Dark matter not exist. I know but you don't. I will give you hint. Gravity does not decrease as expected. You want to know the secrete? Ask me. I will answer.
@TheoChang-z5h Says:
This video was a while ago, does anyone know the results so far yet?
@RicardoZamora-os8du Says:
Thank you.
@skullydully1.0 Says:
6: 05 bro you're just spinning it faster
@skullydully1.0 Says:
Black hole is the one keeping galaxies planets in shape and its swallowing everything slowly super massive blackholes like tons used to be stable galaxies like ours million of years after eating most of the matter orbiting it,it became a super massive bhas we know it today
@izujojo Says:
1:43 dark life matters
@johnwalker863 Says:
These folks need help
@Pro-w4p Says:
If dark matter has mass then won't it too bend space just like planets
@BaeuerleKlaus Says:
The speculation about Good goes on since thousands of years. The speculation about Dark Matter goes on since 90 years. To proof the nonexistence of a fiction was not easy.
Until the design of space telescope Euclid came up. It did not proof the nonexistence of good, but of Dark Matter. Google: zenodo 19078581
@shaziaheavenantonio Says:
Hey!I'm a kid here but I'm interested in astrology and I have an idea they are doing it in June and other months but I think Libra should do it in January since it's the month which the earth rotates around the sun fastest and maybe it could hold more dark matter but this is just a theory really wanted to share this
@felixbaum48 Says:
It is a sobering realization that dark matter may never be directly detected, that it may be part of a much more complex, unseen "dark" version of the standard model

"Under a mountain in the Italian Alps"
*Zooms in on the Appenine, not the Alps*
Alright...
@fumbduck2720 Says:
Wait i thought when anti matter meets matter both are destroyed is a huge burst of energy...
@fumbduck2720 Says:
Is a positron anti matter. An electron that has a an opposing charge. They exsist but are they anti matter. Or does it not count because it isnt matter?
@fumbduck2720 Says:
Maybe time isnt relative at extreme situations. Maybe its the difference in time. The galaxies go faster on the outside because their time is faster. So the center is going slower than it actually appears to be. Gravity cause time to travel more slowly..
@Fernandolunatoro1 Says:
Image what Gus Fring can do with that hole?
@sahlibessam7925 Says:
I always think that the reason the stars doesn’t get flung off into space is because space time is moving towards the black hole in the centre of the galaxy, like a carpet being pulled towards the centre keeping the extra speed kinda irrelevant because the whole canvas is moving
@fleitzify Says:
imagine living in a country where gambling is illegal.
@michaelf8221 Says:
SABRE in SUPL is now live. I want to see an update video once the first results come out!
@Coolfire880 Says:
It may not be dark matter but something simmilar, ghost particles
@keep_walking_on_grass Says:
ist not dunkel materieee its "doonk le ma te ree yeah"
@david99099 Says:
Maybe there is no dark matter.
It is Newtonian physics and General Relativity that breakdown at cosmoslogy level.
@MüllmannJonny Says:
10:45 Can someone explain me how this works if dark matter only interacts through gravity?
@someoneelse318 Says:
Dunkle Materie, you could have easily found out, how to pronounce it.
@glenlongstreet7 Says:
I had a great course in Nuclear Engineering, and then I got assigned to a submarine.
@glenlongstreet7 Says:
I am assuming you have already ruled out neutrinos.
@Kazooples Says:
I like to think that if it correlates with the amount of tourists in Italy, it confirms that it’s Dust

Putting a detector in gold mine was first done by scientist Bibha Choudhury (whose idea was used by Powell , received Nobel prize for the same) .. sad for patriarchal society
@derickroshin2667 Says:
It is the force. It flows around us, it penetrates us, it binds the galaxy togather.
@liambond5653 Says:
dark matter is real, as is bigfoot
@CommunistSupermarket Says:
Priceless, the way you pronounce "Dunkle Materie". 😄
@BasilFawlty64 Says:
Researchers stating Dark Matter as a fact before we know - is that how science is done now? It is! We have zero point singularities as evidence.
Many take Inflation as a fact blah blah blah, but the CMB is how it should look when things 'settle out' normally / naturally - it's not really 'amazing', just how such things work. Everything didn't need to be 'in contact' and then 'inflated'. Saying that isn't exciting, though, and 'exciting' gets noticed and funded.
@jasonpiekacz3271 Says:
I have dark matter for sale. 1$, anyone?
@jameswilliams3270 Says:
Like the UV Catastrophe over 100 years ago, these theoretical roadblocks usually stir creative thinking. Perhaps this is a good example of "non-creative" process, just build more sensitive detector?
@NoSphereCosmology Says:
Im going to laugh.
Dark matter is the boundary layer of the universe.
It is not a particle.
@lukes2219 Says:
The search for dark matter is funny to me. Since when does science find what they’re looking for? Discovery like this is usually by chance. If it exists someone probably will find it by doing some crazy experiment for some completely other reason
@melophonic Says:
This is one of the most powerful things I've watched recently.
