Evidence For Antimatter Anomaly Mounts
sciencehabit writes "The big bang created a lot of matter—along with the same amount of antimatter, which wiped out everything and brought the universe to an untimely end. That's what accepted theoretical physics tell us—though things clearly didn't work out that way. Now, results from a U.S. particle smasher are providing new evidence for a subtle difference in the properties of matter and antimatter that may explain how the early universe survived."
Our universe is just another marble in someone's bag. *sigh*
Life is not for the lazy.
I guess that means I must be in heaven or hell.
Come to think of it, reading the comments on Slashdot does feel a little bit like Purgatory....

So then, its like populating the roads with an equal number of Priuses and Lincoln Navigators?
Have gnu, will travel.
To witness CP violation.... The accepted theory...allows for a low level of CP violation... So researchers have been trying to find cases in which CP violation is higher.
Oh, never mind it stands for charge-parity. One would have thought they would find a better acronym.

Lol so the very fact that there is a universe, in which we can contemplate the laws of physics, is itself a phenomenon that the standard models can't yet explain? Nice. Seems like a minor hole :)
the standard model, allows for a low level of CP violation
Upward mobility is a slippery slope - the higher you climb the more you show your ass.
I rather think J B Cabell preceded MiB. Refer to "The Silver Stallion", if you can find a copy.

Under the highest magnification of our latest scanning tunneling microscopes, new images of these anti particles reveal that they sport tiny goatees.
It should be possible to detect these anomalies by throwing bolts at them and observing the reaction. If you don't have a bolt, the older tool used was a rock covered in a handkerchief with a string tied to it.

2. Are the instruments properly calibrated?

Could be because we use "ordinary" matter to study the phenomena?

It is 41.99999999999999999997 in the Antimatter universe.
I am not a physicist, but couldn't the antimater simply be thrown backwards into what we would call the past.

The research is certainly interesting and important (at least to physicists), but it demonstrates CP violation only in certain relatively rare particles, the neutral D mesons. CP violation has been known to exist for a while (in K and B mesons), so that really is not that ground breaking. On the other hand, as far as I know, these effects are far too small to account for the matter/antimatter imbalance in the universe and additional mechanisms are required.

Did'ja check those cables first?

It would be very weird if all the matter and all the antimatter that was created just got all those matter and antimatter particles close enough to destroy themselves. I think it's not a surprise at all, there definitely were clumps of matter that never saw a single antimatter particles, and the opposite should be true, so some matter and antimatter got in a fight and some didn't. I actually wonder if there are galaxies or at least star systems that are completely made of antimatter and have very little matter there?
You can't handle the truth.
I have not read TFA (sue me). However in this and in many other physics questions, I often wonder if they're over-thinking the problem.
So, Big Bang goes off sending some amount of matter and anti-matter flying off in all directions. The matter and anti-matter in close proximity to each other annihilate each other. Some matter or anti-matter will be left in pockets locally assuming inequal amounts of each landed in proximity to each other.
Why even bother to postulate unequal amounts of each were created when the leftovers of each are just on the other side of the Universe from each other and can't possibly interact with each other at that distance? Wouldn't it be simpler to assume they were equal amounts, but what's left can't possibly interact?

How do we know that there is an imbalance of matter and antimatter? Perhaps this is only the case locally in the observable universe? Is it at all possible that in the whole of the universe there is in fact no imbalance, and for some reason matter and antimatter formed "pockets" where one dominates the other, and we're just observing one of these pockets?

Wow! So Michael McCollum got it right in the Makers series where the difference between matter and anti-matter ends up being a primary plot point... which I won't spoil, but maybe these researchers should peak ahead to the last chapter of the second book, Procyon's Promise, to see what the answer is ;-)
Sorry for accidental duplicate AC post.

Well, if you have enough monkeys banging on enough typewriters...

On second thought, let's not go to Camelot. It is a silly place.
They've found antimatter anomaly saddles, bridles and bits?
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Actually, there's an error with my post (accidentally AC)... McCollum got the idea from Feynman. Basically that antimatter is just regular matter going backwards in time from the big crunch. So, not a glorious case of Sci-Fi presaging science, but a case of Sci-Fi rehashing interesting science.

Argh! There's an error with my post... McCollum got the idea from Feynman. Basically that antimatter is just regular matter going backwards in time from the big crunch. So, not a glorious case of Sci-Fi presaging science, but a case of Sci-Fi rehashing interesting science.
Sorry folks. Bad post and reply to my own post.

I read that as "Pentium 5" (as in P2, P3, P4...), and thought hey, finally proof that parallell universes do exist - and you just crossed over from one!

FTA:
charge-parity (CP) violation—would have allowed normal matter to prevail over antimatter so that normal matter could go on to form all of the stuff we see in the universe today
If the violation had been the other way around we'd probably still call ourselves the ones that matter. Or something. Just like in war, the victor gets to write the history and physics books.
We need to find out why matter is called matter and antimatter is called antimatter and not the other way around.
If Slashdot were chemistry it would look like this:Cadaverine
What I really want to know is if it is possible for antimatter to move faster than the speed of darkness.
If my comment didn't sound as good in your head as it did in mine, then I guess we all know who's to blame
Didn't Lincoln die like in 1865? That's a pretty long half life for Navigators.
They did, but due to relativity, the signal hasn't reached you yet.
