For the first time, scientists detect the ghostly signal that reveals the engine of the universe

"Neutrinos from a long-theorized nuclear fusion reaction in the sun have been definitively observed, confirming the process that powers most stars."

From the link:

In research published Wednesday in the journal Nature, scientists reported that they’ve made the first detection of almost-ethereal particles called neutrinos that can be traced to carbon-nitrogen-oxygen fusion, known as the CNO cycle, inside the sun.

It’s a landmark finding that confirms theoretical predictions from the 1930s, and it’s being hailed as one of the greatest discoveries in physics of the new millenium.

Well now we are a little older to knowing how stars, including our sun, actually work at the subatomic level. Congratulations to the scientists for providing the proof behind almost a century of theorizing.

I don't get it

We've known and have been detecting neutrinos for sometime now.

CNO included

Fermi lab have here in the US have the most advanced neutrino lab and they set up the one at cern for their neutrino experiments.

Am I missing something?

But until npw, the only experimental evidence was of Neutrinos in the pp Chain. This is the first hard confirmed evidence of the CNO chain and thus a first glimpse at what's gpong on in the center of the sun. The pp Chain I believe has more to do with the fusion of Hydrogen and Helium which is more easily seen in the outer shell and during solar flares compared to the CNO chain which shows whats going on at the center of the sun.

Well, I may be wrong, but I think the 'breakthrough' here is that they have detected the CNO process of neutrinos being created, not just the neutrinos themselves.

Yeah same, I thought the Ice cube in the south pole detected the suns neutrinos... this lab is outside of Rome!

Well there goes the electric universe theory.

And Hello to Hyper Dimensional Physics ??

My understanding is that our 3D reality may only a subset of a series of higher hyperspatial additional dimensions.

Current versions of string theory require 10 dimensions in total, while an even more hypothetical theory known as M-theory requires 11 to attempt to explain our universe.

Those virtual particles of Casmir theory populate from somewhere...

Turn it up to 11, cant go wrong.. might be lots of 11s though

So there's different types of neutrinos? How can they tell the difference, are some more energetic than others? Different spin? Different charges? All of the above?

Snake eyes eh?

The worst possible result and a complete lack of success.

Almost a Gnostic interpretation at the roll of the dice.

Hopefully it's no news to anybody that the writiers of these science articles don't know science very well. This is ridiculously wrong:

In the case of the sun, 99 percent of its energy comes from proton-proton fusion, which can create beryllium, lithium and boron before breaking them down into helium.

But most stars in the universe are much larger than our sun: the red-giant Betelgeuse, for instance, is about 20 times more massive and about 700 times as wide.

Most stars are larger than our sun? Let's fact check that:

Stellar Masses

But the Sun is not your run-of-the-mill average star. Look at the pie chart -- it’s hotter, brighter, and more massive than 92 percent of the stars in the galaxy! The Sun is a major force.

The vast majority of stars in the universe are known as red dwarfs.

So the sun is more massive than red dwarfs which are the vast majority of stars in the universe, yet this science writer is telling us "But most stars in the universe are much larger than our sun", this is really sad.

Well now we are a little older to knowing how stars, including our sun, actually work at the subatomic level. Congratulations to the scientists for providing the proof behind almost a century of theorizing.

Yes, the CNO cycle was theorized a little over 80 years ago so it's nice to finally have some evidence of it, but it's not a very significant process in the sun, with only maybe 1% or so of the helium being produced by the CNO cycle m(at least the science writer got that part right when they said "In the case of the sun, 99 percent of its energy comes from proton-proton fusion", it could be a hair less than that but it's close. The CNO cycle is more prevalent in stars more massive than our sun.
