Scientists have found the first evidence for an extremely rare particle decay known as ‘Bd to mu mu’.

The title should have lead with the Zeptoverse instead. Pretty incredible!

Physicists have found evidence of a particle decay so rare that it is expected to occur only around once in every 10 billion ‘beauty’ particles.

The result, from the upgraded LHCb experiment at CERN’s Large Hadron Collider (LHC), follows a search spanning more than 40 years and brings physicists closer to exploring the ‘Zeptoverse’ – an unexplored world that exists at distances of a billionth of a trillionth of a metre, or a ‘zeptometre’, where new particles and forces of nature may be hiding.

Researchers from The University of Manchester have played key roles in the LHCb experiment and its major upgrade - which can now collect data at up to five times its previous rate - including developing detector technology that has helped make the new measurement possible.

Do you have more facts about the zeptoverse? What other analogues do we have to it?

I once asked my physics professor where the forces were. His answer was something like “everywhere”. That answer never satisfied me. This is very interesting! I will have to do some further research on the Zeptoverse.

How else would you describe fields that extend forever in all directions

"Everywhere" seems pretty apt to me

The title is a masterclass in how to alienate people

well, it's not a big deal, you can't really make it sound more exciting than that.

“new particle physics just dropped, it’s called “From Buds to MooMoos” and reveals all about our cannabis and dairy consumption habits!”

No_Departure_1878 | 15 hours ago

They had to call the Higgs Boson the "God" particle to make it more interesting. At least this time it was not called the "Baby Jesus decay" or something.

Well, it was originally called "the goddamned particle" (by Leon Lederman) because it would be so difficult to detect. It got bowdlerised by his publisher to make his book more saleable.

I thought it was about the KLF and got pretty excited for a minute about a potential new album drop

Is the article calling them beauty quarks instead of the more commonly used bottom quarks just because it sounds neat?

From what I can tell, "science" and "academia" long ago abandoned the notion of understanding and explaining things as they are. Instead of using abstractions in order to generalize truths, now the abstractions are used to deceive. So when some theory is found to have a fatal flaw that negates an entire field, instead they just rename that thing and change a couple variables that way it must be re-disproven.

It's like the inverse of this:

>Truth is stranger than fiction. Fiction has to make sense.

Right, well science and history also have to be logical, but that's not a viable way to build a "career"

I recommend reading the pages near the one linked in this book by Philip Warren Anderson. He explains the connections between the military industrial complex, Big Science & academia. Effectively outlining the corruption which is today extinction level severity. This is The Problem. He specifically mentions CERN.

An excerpt:

>That Big Science culture in the USA, and similar groups else- where, tended to have separate, direct access to government and hence to funding sources. It was independent to a great extent of the rest of science, of which it was never a majority component except in funding. In the USA NASA, the Department of Energy (earlier the AEC), and military support operated outside of the standard peer review mechanisms. (The DOE funded other science, but from a separate budget.) The sums involved precluded private support, either by industry, universities, or private foundations; the former came to view Big Science not as an investment but as a "cash cow", a source of very helpful overhead charges and of enlargement of the bureaucracy, if not of actual profits.

>Eventually one could identify an entity (which perhaps was never more than a certain state of mind and set of common interests) which could be thought of as the Big Science subdivision of the military- industrial complex. Whatever one may call it, towards the end of the century a number of controversies or problems arose which indicated that Big Science no longer had unlimited approval from the public nor unlimited access to the public purse. In fact, it is this series of events which have been referred to as "the end of the age of physics".

Title sounds like an anime Xd

Watch it become a title of a manga and then anime in like 15 years time.

How is this relevant to life on earth

The finding will allow physicists to test the Standard Model, our current best theory of fundamental particles and their interactions, with greater precision and search for signs of particles or forces that may lie beyond it. Or in simpler terms: It could help explain mysteries like how matter actually came into existence during the big bang.

you are replying to a bot, likely russian, trying to destabilise Europe. thank you for your work. it is amazing to see such crazy progress!

thechungusamonguss | a day ago

I don’t know what that means. We should focus more on Ai so I can have better sex bots

Scientific discoveries like this may seem useless at first, but they can pave the way for more advanced sex bots down the line

go back to ruzzia, you naughty bot, you won't destabilise us today.

What is this normalized schizophrenic mindset thinking that any provocative comment is from some opposing government agency.

You aren’t that important, bud.
