Researchers at Washington University in St. Louis have discovered and characterized a new form of oxygen dubbed "featherweight oxygen"—the lightest-ever version of the familiar chemical element oxygen, with only three neutrons to its eight protons.

Oxygen is one of the most abundant elements in the solar system, but oxygen-11 can be produced only in a laboratory. It decays immediately after its creation by emitting two protons, and it can be observed solely through detection of its decay products. Two- decay is the most recently discovered nuclear decay channel.

"What is most interesting to the nuclear physics community, however, is that oxygen-11 is the nuclear mirror of lithium-11, a very well-studied heavy isotope of lithium," said Tyler Webb, a Ph.D. candidate in physics in Arts & Sciences at Washington University, who works with Robert J. Charity, research professor of chemistry in Arts & Sciences, and Lee G. Sobotka, professor of chemistry and of physics. Webb is the first author of a new paper on the discovery in Physical Review Letters.

In nuclear physics, nuclei are said to be mirrors when one has a certain number of neutrons and protons and the other has a reversed amount, such as the 3:8 ratio of neutrons to protons in oxygen-11 as compared to the 8:3 ratio in lithium-11.

"When talking about mirror nuclei, we expect a sort of symmetry to hold," Webb said. "The properties of a nucleus and its mirror should be similar: Quantum states should be roughly close in energy relative to the nucleus's and the wave functions of those states should be similar."

This symmetry can be stretched or broken, however. Scientists can compare the actual structure of mirror nuclei against their expected structure to learn more about this important symmetry of atomic nuclei, the stuff that composes the visible matter of the universe.

In this case, the researchers are most excited to compare lithium-11, which they know has two very loosely bound neutrons in a "halo" orbiting its core, to oxygen-11, which has two unbound protons.

The Washington University researchers pieced together evidence of oxygen-11 in an experiment conducted at the National Superconducting Cyclotron Laboratory on the campus of Michigan State University. The Physical Review Letters paper outlines both the experiment and the supporting calculations conducted by theoretical nuclear physicists Witold "Witek" Nazarewicz and Simin Wang of Michigan State University. Researchers from University of Connecticut and Western Michigan University also participated in the collaboration.

Talk about lightweight... heres some truly airy H...

"GAS CHROMATOGRAPHIC ISOLATION AND IDENTIFICATION OF HYDRINO GAS PRODUCED BY THE SUNCELL®
"Hydrino gas was observed to have a faster migration time and a higher thermal conductivity than any known gas as shown by a negative gas chromatographic peak before hydrogen in a helium carrier gas [link]. This data adds to the massive portfolio of other analytical tests that confirm the existence of hydrino [link], a smaller more stable form of hydrogen formed by the release of massive power."

Just as soon as he let's us know how his friend Rossi is doing with his cold fusion reactor that was supposed to be - what was it? - absolutely definitely out and revolutionizing everything like 5 years ago?

Nah rossi has finally proven himself a fraud. IMO of course. His last presentation was one of the most pathetic things I've ever seen. And of course rossi being a loser doesnt mean dr Mills is one as well.

The jury is still out on BLP. They continue to present high-quality, experiment-based evidence that is hard to refute. For those who actually try that is, instead of just sticking their pointy little noses skyward.

-I suppose you could fake a vid of a ss ball repeatedly heating red hot in a few seconds, or a ss box breaching in a flood of white-hot sparks in a few seconds. They do have many millions of seed money to spend after all.

Not. A scam he's been pulling for decades, with a production model just around the corner for said decades.

the likelihood of this being real is considerably lower than you think

the single most studied element in existence has only one person driving the claim that he's reached a point lower than the known, existing, repeatedly demonstrated and validated ground state?

here is a great demonstration of the problem: https://scholar.g...mp;btnG=

out of studies that "claim" isolation of the hydrino, Mills is the (or an) author of them all

at this point, statistically speaking, it is far more likely that you'll be the first person to step onto Mars than that the Hydrino even exists

Personally, I don't care, I can wait for confirmation or debunking, but I also don't see *any* evidence for mills claims

here is another great read: http://kiwi.to/st...0225.pdf

Yes I know Ive heard it all before. Funnily enoughily, your google link lists a number of mills papers.

So apparently youve been to the BLP website and viewed all the vids, and also read his latest papers?

Yes/no?

And I know fidel is just throwing shitbombs as usual so -irrelevant-

[sic] which was exactly the point
So apparently youve been to the BLP website and viewed all the vids, and also read his latest papers?
yes. I've read a lot of his papers, but the videos are irrelevant

it doesn't matter how many public announcements he makes, or how many youtube videos there are (the eu is a good example of this), none of that is considered validation

I'm sceptical because there is plenty of refutation of his hydrino claims in journals, our previous conversations about the physics and the above last link I presented which indicates that the likelihood of his being legitimate is low, considering

and as I said before: I can wait for validation from a reputable source, I just don't think it will ever actually exist, especially under the circumstances

it's not like people haven't examined H before or that they've decided there is nothing more to be gleaned from H

Apr 02, 2019
@otto cont'd
Just for fun tho stumpy, why dont you offer a conjecture on how they could burn through a ss sphere so quickly in the 091918 vid?
first of all, what is "a ss sphere": contents, thickness, design, constraints, materials, additional contents/materials etc
scale mentioned doesn't include this

then I would need to know more about contents of the gas and oxides being used, not just in name, but in amount, etc (it's not listed)

What power constraints do I have?

the vid's are too vague to answer and there is no listed specific data I can build from, but generally speaking, I could probably build a plasma torch or a thermite-like concoction that was about as effective as the vid

NOTE: just because you see it in a vid doesn't mean you're seeing what they're telling you
the proliferation of magic acts is pretty much demonstrative of why it's not conclusive evidence without validation

Just for fun, why don't you look at the real science, and see where anybody has even replicated his idiocy? Why don't you realise that dumb videos are not the way science is done? Why don't you realise that those videos are just nonsense designed to trick the gullible out of their money? Why don't you realise that the ground state of H is called that for a reason? Mills is a con artist. He has made claims of detections that the instrument he was using was incapable of detecting. He is not even qualified in the subject.
Fine, if you want to believe crap like this.... go put your mortgage on it. Wave goodbye to your money. He is a crook. Be warned.

Oh come on. New things about old stuff is being discovered every day. "Not found yet and so never will be found" is hardly a valid argument no matter who it comes from.

"Charles H. Duell was the Commissioner of US patent office in 1899. Mr. Deull's most famous attributed utterance is that "everything that can be invented has been invented.""

and again: thinckness? solid? what type SS? are there other materials involved?
"Not found yet and so never will be found" is hardly a valid argument no matter who it comes from
that isn't the argument
the argument is: there are sh*tloads of people looking at H other than mills, especially considering mills has claimed to have refuted quantum mechanics with his hydrino's

IMHO - from any layman's perspective, excluding conspiracy nutters:
if we have an established theory (QM) that is repeatedly still tested,
with claims about an element (H) that is also repeatedly still tested,
while not having either validated in any reputable way despite the longevity of the claims,
then it's far more likely the claims are false, especially as there have been numerous refutations of mills claims from multiple journals (previously linked elsewhere)
may I have some pudding now?
how can you eat your pudding if you don't eat your meat?

so, mills used an old tank manufactured during an age where consistency between batches of material wasn't always considered due to the nature of the rush to produce?
[humour intended]

but seriously: what, exactly, can be validated from mills videos?

how do you know it's not set up to look like [x] while actually being [y]?

the only way you can do that is to accept the premise and subsequent explanations offered by mills

if all it took was establishing a premise and subsequent explanation to be scientifically correct, factual or valid, then cd, rc and zeph would be insanely famous for their groundbreaking discoveries

CS, mate, seriously, you need to stop being so sneaky and wrong about me; for your own sake if nothing else. Ok? :)

And when will you realise that not only am I totally different from all posters here (me being the most strictly independent, objective and impartial observer/researcher); I am also the only one here increasingly being confirmed correct on many fronts by recent mainstream astro/cosmo/QM discoveries/reviews. Stop your sneaky/wrong juvenile campaign against me, CS; for science and humanity's sake if not your own internet reputation's sake. Ok? :)

What could be validated from wright bros flights? Stumpy would be reading about it in the papers (old news venue) and be asking 'Those photos are irrelevant... is that a blimp with a guide wire?

Tell you what - just watch a few more sofilein vids and youll forget all about validation.

BTW zeph never had a cool lab full of ss equipt, oscilloscopes, and hydrino haze. And millions in seed money. And a little black mercedes in the parking lot.

mills hasn't been able to prove that he has a hydrino haze either, so that's not saying much except that he spends money on equipment
And millions in seed money
true: zeph lives in a crappy apartment (by US standards)
but saying that because mills has money then something must be true is like saying that because solar freakin' roadways got millions then it'll work beautifully (analogy cogent, IMHO)
And a little black mercedes in the parking lot
zeph actually might have a Merc... they're like chevy or ford over there, even in his neck of the woods
Stumpy would be reading about it in the papers
obviously you've never heard of the "Great Moon Hoax" of 1835

@CS,
You are probably well aware of the long-running threads on BLP on International Skeptics Forum, where this has been debunked to hell and back. There is so much evidence to show that this Mills clown is either a conman and/ or totally incompetent, that it would be impossible to detail it all here. I defer to Nobel laureate Phillip Anderson;

If you could f*** around with the hydrogen atom, you could f*** around with the energy process in the sun. You could f*** around with life itself. Everything we know about everything would be a bunch of nonsense. That's why I'm so sure that it's a fraud.

No its drawing conclusions while claiming to be merely skeptical in your earlier comments. Which is it?

"the cosmological constant problem or vacuum catastrophe is the disagreement between the observed values of vacuum energy density (the small value of the cosmological constant) and theoretical large value of zero-point energy suggested by quantum field theory."

-Lots of problems left to solve which unfortunately (for you guys) or fortunately (for eager young scientists and mills, whatever he is) leaves lots of room for unexpected new theories.

"Arthur C. Clarke Quotes. If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong."

@otto
Which is it?
I'm a sceptic who has drawn a tentative conclusion based upon the evidence but who is willing to change his mind should evidence be presented to the contrary

there is nothing that he has presented that can be considered scientific evidence overturning QM, yet his continued claims are that he has
Lots of problems left to solve ... leaves lots of room for unexpected new theories
I don't dispute that there are problems to solve or unexpected new theories
I just dispute that mills has produced anything overturning QM
also applies to aging physorg commenters
I'm stating that it's not demonstrated, his conclusions are improbable, he's not had any corroboration, and that he's not shown how it is possible

it's a mite different than stating it's impossible

"Um, he's been showing it - the SunCell type of reaction - to the world for the last five years. During that time the advancements have been very apparent.

No he has not. He shows youtube videos that are easily faked and he fails to provide the convincing evidence that he claims to have.

BTW how are "the advancements have been very apparent" when in 2016 he was claiming to be delivering prototypes ready for commercialization to a third party and now that has fallen through and he has no projections on when he's going to actually do that?
