Experiments Create Particles Out of a Vacuum Using Neutrinos
BarbaraHudson writes: In a new series of experiments, scientists report (abstract) that neutrinos, notable for how infrequently they interact with matter, can strike a glancing blow on an atom's nucleus, and the side effect is the generation of a new particle out of a vacuum. Professor Kevin McFarland says the creation of the new particle is what shields the nucleus from being blown apart by the collision. "Producing an entirely new particle – in this case a charged pion – requires much more energy than it would take to blast the nucleus apart – which is why the physicists are always surprised that the reaction happens as often as it does. McFarland adds that even painstakingly detailed theoretical calculations for this reaction 'have been all over the map.'"
Is this a way to generate... gravity? I am not a theoretical physicist, but aren't pions once-removed from gravitons? I remember reading and failing to understand something about pion-graviton scattering.
Its probably best to read the instructions
Its better with to ones that have a bag. Those ones with just a cylindrical plastic container that you just tip into the garbage can - even if you don't spill it, some of the smaller particles are going to get back into the air that you breathe.
I thought a vacuum was a "space" devoid of particles. How do you get something from nothing? I'm not inclined to say their vacuum leaked and this is stray contamination.
It's just like work: a bunch of pions popping in and out of a corporate vacuum.
Table-ized A.I.
As usual for physics articles, a non-paywalled version is available on arXiv, and has been so for more than a month before it appeared behind the paywall. Why do people who submit physics stories to slashdot aloways link to the useless paywalled version?
Well, we can now create something from just energy and the something that is nothingness.
Now if we can just figure out how use glancing blows from particle accelerators to create "good" where there's just "elected officials".
The link in the summary goes to the wrong paper.
This is the link to the right pre-print paper: http://arxiv.org/abs/1409.3835
out of vacuum using water.
The summary is horribly incorrect. There are no new experiments, only new analysis of old experiments. The authors didn't actually do the experiments but "digitize and reanalyze data from both experiments." The summary didn't include the non-paywalled version of the article on arXiv. The summary sensationalizes the results with phrases like "[p]roducing an entirely new particle." (ok it is a quote) which leads non-physicist readers to think this is a new particle as yet unseen when in fact all particles involved are well known. Furthermore, pulling a particle out of the vacuum, especially near such massive and charged objects a nuclei is not at all uncommon. Sure it is a non-electromagnetic process but it isn't odd.
TFS's topic of "Experiments Create Particles Out of a Vacuum Using Neutrinos" is not discussed in the paper
of 18 Nov which you linked, but in McFarland's 25 Nov paper
From the latter,
Actually, to be on the safe side, while you don't understand what you're doing, could you please do it in Alpha Centauri?
If you find a way to block high energy neutrinos from space reaching Earth, then moving equipment to Alpha Centauri should be easy by comparison...
Scientists were surprised with penicillin.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
Earl Grey, hot.
Have gnu, will travel.
Pretty sure the title of TFS should have been:
I've fallen off your lawn, and I can't get up.
Toto's on his way to be tutored. They caught him playing with unleashed atoms, now they have to figure out who's going to take all the little pions.
I've fallen off your lawn, and I can't get up.
> If you find a way to block high energy neutrinos from space reaching Earth
Good point, and a tranquilizing one at that... let's hope the scientists just don't do anything that doesn't happen naturally...
...the Curie couple (both radiation poisoned).
While he probably was radiation poisoned, he actually died from a wagon wheel running over his head.
Now they can create solar neutrino panels so I can get power at night.
The charged pion decays to a muon neutrino that goes off to interact with another nucleus that spawns another charge pion and so on.
Wouldn't the universe fill up with neutrinos eventually?
Barbarahudson started it with apk. Apk finished it and her with it (look for yourself in post parent to his link apk posted above, here http://tech.slashdot.org/comme... ) and since we know you troll and stalk by ac posts Barb, by your own admittance quoted here http://slashdot.org/comments.p... and then you try to hide it by downmods (which most here see anyway since they browse below the -1 moderation threshold default) your attempt at hiding it here http://slashdot.org/comments.p... is moot. This is nothing new. You do this to yourself all the time.
