There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%, thanks to a new experiment on the nuclear processes responsible for the creation of lithium. This research could point the way to a more complete understanding of the early universe.

There is a famous saying that, “In theory, theory and practice are the same. In practice, they are not.” This holds true in every academic domain, but it’s especially common in cosmology, the study of the entire universe, where what we think we should see and what we really see doesn’t always match up. This is largely because many cosmological phenomena are difficult to study due to inaccessibility. Cosmological phenomena are usually out of our reach because of the extreme distances involved, or often they have occurred before the human brain had even evolved to worry about them in the first place — such is the case with the big bang.

Project Assistant Professor Seiya Hayakawa and Lecturer Hidetoshi Yamaguchi from the Center for Nuclear Study at the University of Tokyo, and their international team are especially interested in one area of cosmology where theory and observation are very misaligned, and that is the issue of the missing lithium, the cosmological lithium problem (CLP). In a nutshell, theory predicts that in the minutes following the big bang that created all matter in the cosmos, there should be an abundance of lithium around three times greater than what we actually observe. But Hayakawa and his team accounted for some of this discrepancy and have thus paved the way for research that may one day resolve it entirely.

“13.7 billion years ago, as matter coalesced from the energy of the big bang, common light elements we all recognize — hydrogen, helium, lithium and beryllium — formed in a process we call Big Bang nucleosynthesis (BBN),” said Hayakawa. “However, BBN is not a straightforward chain of events where one thing becomes another in sequence; it is actually a complex web of processes where a jumble of protons and neutrons builds up atomic nuclei, and some of these decay into other nuclei. For example, the abundance of one form of lithium, or isotope — lithium-7 — mostly results from the production and decay of beryllium-7. But it has either been overestimated in theory, underobserved in reality, or a combination of the two. This needs to be resolved in order to really understand what took place way back then.”

Lithium-7 is the most common isotope of lithium, accounting for 92.5% of all observed. However, even though the accepted models of BBN predict the relative amounts of all elements involved in BBN with extreme accuracy, the expected amount of lithium-7 is around three times greater than what is actually observed. This means there is a gap in our knowledge about the formation of the early universe. There are several theoretical and observational approaches which aim to resolve this, but Hayakawa and his team simulated conditions during BBN using particle beams, detectors and an observational method known as the Trojan horse.

“We scrutinized more than ever before one of the BBN reactions, where beryllium-7 and a neutron decay into lithium-7 and a proton. The resulting levels of lithium-7 abundance were slightly lower than anticipated, about 10% lower,” said Hayakawa. “This is a very difficult reaction to observe since beryllium-7 and neutrons are unstable. So we used deuteron, a hydrogen nucleus with an extra neutron, as a vessel to smuggle a neutron into a beryllium-7 beam without disturbing it. This is a unique technique, developed by an Italian group we collaborate with, in which the deuteron is like the Trojan horse in Greek myth, and the neutron is the soldier who sneaks into the impregnable city of Troy without tipping off the guards (destabilizing the sample). Thanks to the new experimental result, we can offer future theoretical researchers a slightly less daunting task when trying to resolve the CLP.”

Sheesh! All that effort to make devise and perform experiments with careful observations and then update the model for greater accuracy.

It would have been far more straightforward to just alter the original observations to match the models as per climate science.

Must be something lost in translation. They studied how the most common isotope of lithium can form from beryllium decay in order to figure out why 2/3 of the lithium is missing and somehow that explained 10% of the gap. But they didn’t actually do the experiment because it’s hard. So they needed to have a diversion. Let’s talk about Trojan Horses, that’s always interesting. The substitute experiment shows that the rate of Be destruction was 10% less than expected when the neutron is in a deuterium nucleus which I guess is totally the same as a neutron or they made an adjustment calculation that has to be right. And that resolves why the theoretical rate is wrong. Got it.

Oh I see the problem. It’s an article from EurekAlert!

No, for some reason Li-7 was not tested for fast neutrons, and when fusion burn started producing those, the deal was done. Li-7 was split to He-4 and H-3 and neutron. Unexpected extra Tritium fuel added to better burn efficiency and produced more fast neutrons causing more fissions in the uranium tamper of the secondary.

We scrutinized more than ever before one of the BBN reactions, where beryllium-7 and a neutron decay into lithium-7 and a proton.

As far as I can tell, the number of electrons and protons in the universe closely equal each other. Otherwise the universe would have a net charge which, presumably, we would observe. So, why don’t they mention the extra electron? Why isn’t one of the decay products a hydrogen atom?

Why isn’t one of the decay products a hydrogen atom?

Because 20 minutes after the Big Bang the universe was still too hot for stable atoms to form.

It took around 300,000 years before temperatures cooled enough (to ~3000°C IIRC ?) for that to happen.

I’d still like to know what happened to the missing electron. In the temperature, radiation, density, pressure regime that existed then, were the laws of physics different? The above experiment notwithstanding, I’m guessing there’s no way to create those conditions in the laboratory.

I’d still like to know what happened to the missing electron.

Looking for “plasma” led me to the Wikipedia “Photon epoch” page (direct link), which provides as good an explanation as any other I’ve seen :

The photon epoch started after most leptons and anti-leptons were annihilated at the end of the lepton epoch, about 10 seconds after the Big Bang. Atomic nuclei were created in the process of nucleosynthesis which occurred during the first few minutes of the photon epoch. For the remainder of the photon epoch, the universe contained a hot dense plasma of nuclei, electrons and photons.

370,000 years after the Big Bang the temperature of the universe fell to the point where nuclei could combine with electrons to create neutral atoms.

With electrons being so much lighter than nuclei they move faster at any given temperature, so observers tend to focus on the “slow moving” nuclei and ignore the intermingling (not “missing” …) electrons whizzing around and between them in a quantum-mechanical “probability cloud”.

The laws were the same, but there was sufficient energy (temperature) for everything–including bare protons–to remain ionized. The temperature for complete ionization of hydrogen is a bit above 10,000 K, which is easily reached in the lab.

mcswelll

At the energies involved, no: the Hydrogen is completely ionized, making it a proton. Eventually the proton will slow down and encounter an electron somewhere, and only then will it become Hydrogen.

Not really. What the group did was measure the cross section and found that it was lower than previously thought by 10%. And given that the abundance of Lithium depends exponentially on the cross section then a small change in the rate can lead to a large difference in abundance.

Say what?

In their own words…

However, even though the accepted models of BBN predict the relative amounts of all elements involved in BBN with extreme accuracy, the expected amount of lithium-7 is around three times greater than what is actually observed.

There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%

The resulting levels of lithium-7 abundance were slightly lower than anticipated, about 10% lower,” said Hayakawa

The predicted abundance (which is about 3x more than observed prior to this theory) was lowered by 10%. So now their tweaked model predicts 90% of the original model’s Li-7 abundance, but reality is (still) only around 33%. So with the new model there is still a 90/33 = 2.7x discrepancy with reality (off by 1.7x).

They have a real crisis on their hands :

Here Dr. Lerner deals precisely with Lithium, in episode 1.
There is a BBN scorecard, and it grades an F.

What is amazing is the prevailing Narrative has feet of clay. A wag said it is as if the emperor’s elbow shows through, then a toe, then an ear, until a kid says the obvious.

The way out of this impasse, is actual science, actual lab work. Fusion is the driver and it needs funding, not only for great energy benefits but Narrative demolishing. This is the only way to deal with scientism.

Thanks for the link.

Watched all of his “BB is crap” videos, really goes to electromagnetic basis of the universe without going into the electric universe per se. Yes, I think, with my limited knowledge, that the BB IS CRAP. When you need to invent new phenomena to make your theory work, and the new phenomena are disproven by experimentation, then your theory is repeatedly disproven.

Of course the one thing both his perspective/theory and the BB have in common is they both rely on gravity, but neither defines WHAT gravitation is as a force. They can explain what it does, but not HOW it is created.

He is interesting. He is into leftist causes, is seeking funding for fusion, and is playing up the energy crises and AGW BS to get said funding.

It amazes me that an outside the box thinker when cosmological dogma is concerned can accept the global warming dogma for his own benefit. A true indication of the progressive mind, only look at a position with regards to its effect for your personal benefit.

But, being a conservative, I looked at his videos and judged them independently to his politics. I did not scream, he is a BB DENIER, and disbelieve!! A lesson to all our griff, Simon, etc. posters. Be more conservative in your thought, look at WHAT is said, not WHO said it. I read their posts, do a little research when they bring up something new, and then determine if it is their typical blather. 97% of the time it is just BS, the rest there may be some added knowledge FOR ME to review and use.

(The 97% is for the consensus, the reality is 99%+ is BS, generally in the form of goal post moving and cherry picking)

He is one of the few harnessing self-organizing plasma processes. He notes a kind of phase shift in cosmology where plasma dominates, then gravity.

As for funding, the new Biden Infrastructure, like Trump’s , has no place for fusion. This has been going on for decades.

BBT is a lie and total BS full of untestable variables and unexplainable things (such as hyperinflation made up to explain holesnin the theory).

There are hundreds of observational paradoxes, besides the Lithium problem, that kill the big bang theory.

What is required is a succinct summary of the observational paradoxes, to break the paradigm.

This is more on the Lithium problem.
 
https://arxiv.org/abs/1203.3551v1
 
….but 7Li observations lie a factor 3 − 4 below the BBN+WMAP prediction. This 4 − 5σ mismatch constitutes the cosmic “lithium problem,” with disparate solutions possible.
 
For example there is Baryon Asymmetry Paradox also called the Anti-matter problem/paradox.

The Anti matter problem is only a problem for the Big Bang theory. i.e. The Big Bang theory ‘predicts’ that theoretically there should be equal amounts of anti-matter and matter in a big bang created universe.

There is no observational support for the existence of any antimatter in the universe.

http://en.wikipedia.org/wiki/Baryon_asymmetry
 
The baryon asymmetry problem in physics refers to the fact that there is an imbalance in baryonic matter and antibaryonic matter in the observable universe.

Neither the standard model of particle physics, nor the theory of general relativity provide an obvious explanation for why this should be so, and it is a natural assumption that the universe be neutral with all conserved charges.[1]

The Big Bang (William if it happened) should have produced equal amounts of matter and antimatter, as such, there should have been total cancellation of both. In other words, protons should have cancelled with antiprotons, electrons with antielectrons (positrons), neutrons with antineutrons, and so on for all elementary particles.

This would have resulted in a sea of photons in the universe with no matter. Since this is evidently not the case, after the Big Bang, some physical laws must have acted differently for matter and antimatter.

The 2.7C signal is not isotropic Paradox

The 2.7C signal is not Isotropic and has patterns that indicated it is emission from dust that is aligned with a magnetic field paradox.

The Big Bang theory was created based on the assumption that the only natural way astronomers could think of to create the 2.7C signal which is incorrectly called the Cosmic Microwave background signal…..

Is a Big Bang event that created all of the matter in the universe 13.7 billion years ago.

The signal which is called the Cosmic Microwave Background radiation …. Should if that signal was caused by a Big Bang event be isotropic.

The 2.7C signal which is incorrectly called the Cosmic Microwave Background radiation appears to be caused by dust that surrounds every galaxy. The dust is aligned to a magnetic field which explains why the signal has a dipole and hemispheric asymmetry.

https://arxiv.org/pdf/1510.07929.pdf
CMB anomalies after Planck
Among those features is:
1)   a lack of both variance and correlation on the largest angular scales,
2)    alignment of the lowest multipole moments with one another and with the motion and geometry of the Solar System,
3)   a hemispherical power asymmetry or dipolar power modulation,
4)   a preference for odd parity modes
5)   and an unexpectedly large cold spot in the Southern hemisphere.
 
Some pairs of those features are demonstrably uncorrelated, increasing their combined statistical significance and indicating a significant detection of CMB features at angular scales larger than a few degrees on top of the standard model. Despite numerous detailed investigations, we still lack a clear understanding of these large-scale features, which seem to imply a violation of statistical isotropy and scale invariance of inflationary perturbations.

Inflation is an invention of Big Bang theorists. ‘Inflation’ is a hypothesized expansion of the universe at 100,000 times faster than the speed of light. This expansion of ‘space’ is called “inflation’.
 
DARK MATTER search failures
After more than 50 years the direct search for dark matter has been negative which would make sense if dark matter does not exist. And that makes sense as simple direct search for dark matter in the local universe finds there is no dark matter.

Serious Blow to Dark Matter Theories?
New study finds mysterious lack of dark matter in Sun’s neighbourhood
 
The most accurate study so far of the motions of stars in the Milky Way has found no evidence for dark matter in a large volume around the Sun. According to widely accepted theories, the solar neighbourhood was expected to be filled with dark matter, a mysterious invisible substance that can only be detected indirectly by the gravitational force it exerts. But a new study by a team of astronomers in Chile has found that these theories just do not fit the observational facts. This may mean that attempts to directly detect dark matter particles on Earth are unlikely to be successful.
 
 
“I’ve been looking for dark matter for 23, no, 24 years now,” he says. And he is not alone; the search for dark matter has grown into a small industry, albeit one that does not yet have a product to sell. “Every experiment has reported essentially negative results. No one even knows for sure if the damn stuff really exists. Those fellows,” Gaitskell says, nodding to the pit, “know exactly where the gold is.” I realize now he is not feeling empathy for the miners. He is feeling envy.

If your ‘eso’ link above is correct, they are finding essentially zero gravitational attraction from supposed dark matter content in the Earth’s vicinity. That is to say, there is zero local gravitational attraction from dark matter, hence zero dark matter. However, the overall motion of the Earth and everything else in our solar system within the galaxy is supposed to be as fast a velocity as it is, precisely because of a significant extra attraction to the galactic center. That is, there is extra acceleration toward the center of the galaxy, hence extra gravitational force in that direction, and thus a very significant dark matter density extending from the galactic center all the way out to our vicinity.

In light of the above, we have both lots of dark matter overall and also *no* dark matter, all at the same time! So, tea and no tea, anyone?

There are several more paradoxes that invalidate the Big Bang Theory. Here’s a further discussion of these flaws revealed by observation and an alternative cosmology.

The moral of the story is that in order to mitigate corruption that stems from attachment of special and peculiar interests to pet theories, we need to practice a separation of logical domains, where science is, with cause, notably a philosophy and practice in the near domain.

No lithium problem!
Dark lithium! There, the theory now works.

What I got from this article is that the cosmologist community has had a theory for decades that our universe is missing two thirds (66%) of its lithium since a few minutes after 13.7 billion years ago… But now evidence has been advanced that in fact, its only missing 60%.

I have a hunch that a parallel universe has developed more rapidly than ours, and has been siphoning off our lithium to power its electronic devices, having depleted its own supplies.

Yes, but the amount of fossil fuels they had to burn in that parallel universe in order to draw our lithium into their universe would simply horrify the greens. 😉

I know! I know! Clearly aliens have bipolar disorders in vast quantities and have consumed it all. 😀

Now if only we could figure out how the Solar System has so much phosphorous while the Universe is pretty depleted.
