The Universe Has A Lithium Problem

he missing lithium problem is centred around the earliest stages of the Universe: from about 10 seconds to 20 minutes after the Big Bang. The Universe was super hot and it was expanding rapidly. This was the beginning of what’s called the Photon Epoch.

At that time, atomic nuclei formed through nucleosynthesis. But the extreme heat that dominated the Universe prevented the nuclei from combining with electrons to form atoms. The Universe was a plasma of nuclei, electrons, and photons.

Only the lightest nuclei were formed during this time, including most of the helium in the Universe, and small amounts of other light nuclides, like deuterium and our friend lithium. For the most part, heavier elements weren’t formed until stars appeared, and took on the role of nucleosynthesis.

The problem is that our understanding of the Big Bang tells us that there should be three times as much lithium as there is. The BBT gets it right when it comes to other primordial nuclei. Our observations of primordial helium and deuterium match the BBT’s predictions. So far, scientists haven’t been able to resolve this inconsistency.

But a new paper from researchers in China may have solved the puzzle.

...

The authors applied what is known as non-extensive statistics to solve the problem. In the graph above, the dotted lines of the author’s model predict a lower abundance of the beryllium isotope. This is key, since beryllium decays into lithium. Also key is that the resulting amount of lithium, and of the other lighter nuclei, now all conform to the amounts predicted by the Maxwell-Boltzmann distribution. It’s a eureka moment for cosmology aficionados.

Lithium ? I think Jimmy Piersall used it all.

And that's the problem with your Churchian weirdos. Anybody that has a problem with your weird rants when they are CLEARLY not appropriate, that person either doesn't believe in God or is going to Hell.

The thread was about Lithium, and you IMMEDIATELY turn it into a sermon and condemn to Hell anybody that pushes back.

Crawl back under your rock. Tell HiTech Redneck we all said hi.

So, the Big Bag started when God’s Samsung Smartphone exploded?

The Universe was super hot and it was expanding rapidly.

Expanding into what? What is the medium or container, into which it was expanding?

I had retorted;

"A lot of fancy words to just say, "I don't believe in God" I never said anything about condemnation nor Hell (Catholics believe in Purgatory), but that There are consequences for the decisions we make and I believe (by MY wording) that there is a conscious afterlife and we will all know it in a nanosecond following death."

Which, in an of itself is safely non accusatory but for the statement that implies you don't believe in God which, perusing your comments in the forum, you apparently don't seem to do.

The fact that you have derisively used "Christian" as an epithet against Christians further validates that stand.

All you have to do is say you don't believe in God nor my statement that God spoke creation into existence.

You're a seriously flawed conversationalist and debator and you look down on the people here in FreeRepublic.

We're people, just like you, with as much a modicum of intelligence as you and we attempt to discuss any and all matters with the intent to amuse, educate and perhaps correct a wrong.

Only a few are mean and nasty
