FAQ - Antihydrogen Fusion Reaction ?[edit]

What would the expected consequences of an antihydrogen fusion reaction be ? Is it possible ? Would the effects be similar to hydrogen fusion with the exception of the creation of antihelium instead, or would it be expected to behave differently ? —Preceding unsigned comment added by (talk) 20:02, 18 November 2010 (UTC)

It would behave the same way, theoretically. Practically, it would be very difficult to achieve since it would be almost impossible to keep the antimatter from bumping into matter. Stonemason89 (talk) 05:56, 21 November 2010 (UTC)

Antihydrogen fusion exists now created by lightning. Relativistic Perturbation Mantle is the name for this. A new discovery in Lightning physics that revealed the very centerpiece in the reproduction cycle for many things in the universe...Dark matter producing Dark energy and earths biosphere... "Relativistic Perturbation "Mantle"

When hydrogen sits at an high altitude weightless environment of lightning, it creates a disc of antihydrogen fusion. In the construction process this fusion creates rings of Carbon, Liquid oxygen cooling the fusion back to carbon sealing and surrounding a 2 dimensional 12 foot disc of fused negative energy (anti-hydrogen fusion). This combination traps the energy allowing for the conversion of the first carbon ring to high energy photons "dark energy" still producing high energy photons in the configuration of the Fibonacci sequence and then disappears "dark matter" only to reappear (as seen on NASA video) when the fusion is cooled back to our dimension as a Sprite. This is known as the Fibonacci sequence for all life. When Mantle consumes the first carbon ring it allows the paramagnetic Liquid Oxygen to rush in producing Sprite's above storms. This witnessed event is documented and by current sciences. Mantle for short produces Gamma rays found by NASA's FERMI satellite during Sprite production. PAMELA satellite found the anti-protons around the Van Allen belt produced by Mantle's energetics discharge. Mantle's reproduction will lend efforts to traveling as dark energy exceeding light speed "Warp" travel, wormhole production and dimension technology. The release of charged liquid Oxygen is converting to Air/water for the atmosphere and electrons for the Ionosphere. I want to reproduce this energy placing the devices at farms to make water firsthand selling energy making food free eliminating welfare. fulely — Preceding unsigned comment added by Fulely (talkcontribs) 12:11, 6 September 2014 (UTC)

Old discussions[edit]

On the AntiMatter page it says this was made already in 1995 ! Doesn't it say here 2002 ? Which is correct? Sebastian Haase

I've just changed the article. You can find a preprint about the experiments in 1995 here. 01:45, 7 Dec 2004 (UTC)

After some searching, i've found out the Particle accelerator are constructed as we speak, and estimated to be finished in 2q of 2007 -- 21:57, 19 August 2006 (UTC)

This source [1] says Fermi also generated antihydrogen, and credits a SLAC researcher, Charles Munger, with coming up with the approach used to find antihydrogen.

Is it just me, or does source 3 only describe a potential method for trapping low temperature anit-protons, and does not actually report it having been achieved? —Preceding unsigned comment added by (talk) 22:37, 17 November 2009 (UTC)

Proposed name...[edit]

... as h-bar. Do we have a reference for this? It seems strange that a species of interest only to physicists would be given a name which could easily be confused with the reduced Planck constant. Brammers (talk) 16:57, 5 January 2010 (UTC)

I have removed it, but please reinsert with a reliable cite. -84user (talk) 17:40, 15 July 2010 (UTC)
Please put it back with a {{citation needed}}; it seems to be legit information: Here is an official site that is uses the symbol. I can't immediately find a webpage that specifically mentions that the h-bar symbol is used to represent antihydrogen. here and here are links to two more unrelated pages that use it.
I do not know which institution decides these things: Wikipedia doesn't seem to know and Google doesn't return any relevant results to my limit searches. If somebody knows which organisation officially decides on the symbols, I expect you can find a publication that has more details from them.     — SkyLined (talk) 18:38, 15 July 2010 (UTC)
I added text that some physicists use the symbol and others use the word "hbar", using three cites as examples. -84user (talk) 19:43, 15 July 2010 (UTC)
Perfect, thanks! (talk) 21:43, 15 July 2010 (UTC)

- all journal articles that use a symbol use H-bar - written as H with an overline - so it's really not much of a debate. I've updated this in the entry - there is no ambiguity Planck's constant is allways lower-case h (massen (talk) 08:25, 5 October 2010 (UTC))

uninformative text removed[edit]

A potential solution to this problem would be to produce antihydrogen atoms at such a low temperature (perhaps a fraction of a kelvin) that they can be captured in a magnetic trap or a combined rf trap.

I removed the above text, and its hidden html comment, as it simply told the reader nothing. It was the equivalent of: Problem is AH is too hot; solution is make AH not so hot. That is not a solution. -84user (talk) 18:02, 9 June 2010 (UTC)

available for purchase? really?[edit]

and is it ever going to be? I feel like that's saying that nuclear bombs are not available for purchase or that the washington monument is not available for purchase. I would think that that section should be removed. Sompm (talk) 07:11, 9 July 2010 (UTC)

I agree. I removed it. -84user (talk) 17:42, 15 July 2010 (UTC)

Antimatter atom trapped[edit] ... needs updating. --Kslotte (talk) 22:33, 17 November 2010 (UTC)

It's been updated. —Preceding unsigned comment added by (talk) 17:31, 19 November 2010 (UTC)
Is this discvery only a one sentence thing? --Kslotte (talk) 17:55, 19 November 2010 (UTC)
Be WP:BOLD! Rursus dixit. (mbork3!) 07:57, 20 November 2010 (UTC)


What is it please tell me. (talk) 15:33, 10 January 2014 (UTC)

Duh. A Molekule, consisting out of two Antihydrogen atoms and one Antioxigen atom. Just replace the particles water consists of, with their respective antimater counterparts. -- (talk) 14:55, 11 January 2014 (UTC)
Of course, unlike normal water, drinking antiwater should probably be the last thing that crosses your mind. (As it would be if you tried it.) Double sharp (talk) 04:35, 29 September 2015 (UTC)

Cost estimate[edit]

It strikes me that a direct scaling up may give readers a slightly wrong impression: no doubt antihydrogen would cost less per gram if we could actually make a whole gram. Double sharp (talk) 10:36, 6 February 2018 (UTC)
