Antimatter Atoms Captured

Whamo writes: "Researchers at CERN think they have created and stored thousands of antiatoms in a particle trap. The researchers first used powerful magnetic fields to trap antiprotons then exposed this to a beam of positrons. Initial results indicate that at least some of the antiparticles have bound together to become neutral antihydrogen atoms. How cool is that?"

    Well, that would depend on how fast the anti-hydrogen atoms are moving, wouldn't it?

    Last time I heard about any "really new" developments in antimatter, they were just figuring out how to contain 10-100 protons (circa 1992) (I know, I'm dating myself, whatever. :-) This is really cool news.

    Still, even a million atoms is really physically small. I wonder

    Anyway, just my $0.01. :-)

    I know that the dept tag is supposed to be funny, but the real benefit of this research is insight into very powerful propulsion systems. No? Not very sustainable at our current rate but definitely the next step toward reaching deeply into space.
    Of course, anti-matter engines are waaaaaaaay off, but I think that we should see from the next-stop-Crab-Nebula dept. rather than from the I-frag-way-too-much dept.

      Actually, we already have anti-matter engines, they're just not very sophisticated. Pennsylvania State University and NASA are investigating these drives. The drive could power a mission to Mars in 120 days. That's: go to Mars (30 days), stay for 30 days, and come back (30 days). Sum: 120 days. That's awesome.

  4. In Related News... CERN Disappears by Myriad · · Score: 5, Funny
    In related news the CERN research facility was blown off the map yesterday in what experts are calling a catastrophic power failure.

    Around 9:30 last night a burrowing squirrel shorted out electrical lines causing an initial power surge followed by a blackout.

    Experts believe that researchers had the magnetic containment field generators connected to a household UPS, which proved unable to keep the field in place.

    The result of the containment failure has been described as being very similar to that of a "collapsing hrung." Unfortunately nobody has been able to identify what a hrung is, nor why one should choose to collapse on the CERN facility.

    ......one of the first things some scientist did after they managed to do capture the stuff was suddenly yell "Antimatter containment is failing! We're gonna have to eject the core!!!!!!!!" before falling to the floor laughing hysterically?

    You know there has to be someone, somewhere who is just dying to be the first person to say that.

  8. Re:AntiHydrogen atom? by s20451 · · Score: 5, Informative

    The mass of an antihydrogen atom is roughly 1e-27 kilograms, the same as a hydrogen atom. Using Einstein's famous formula, with the speed of light given as 3e+8 meters/second, the annihilation of one anti-hydrogen atom and one hydrogen atom would produce 2*(1e-27)*(3e+8)^2 = 1.8e-10 joules. The specific heat capacity of water is 4.2 J/(g*K), so 1.8e-10 joules would raise a 300g cup of coffee by 1.4e-13 degrees Kelvin. (I haven't had my coffee yet ... does that sound right? Anyone?)

    The point is, one hydrogen atom makes little difference, but annihilating kilogram's worth of hydrogen atoms would liberate 9,000 terajoules of energy. Compare that to a kilogram of coal, wood, or oil ...

    A gram of hydrogen contains about 6x10^23 atoms. Therefore, a "few thousand" weighs about 10^-20 grams -- much less than even the smallest virus.

    Western Digital 120 GB HD = 1.32 lb (+/- 0.14 lb)

    120 GB = 598.742 g
    122, 880 MB = 598.742 g
    125829120 KB = 598.742 g
    128,849,018,880 Bytes = 598.742 g (+/- 63.5029g)

    12 byte virus = 4.6^-10 grams (+/- .43^-10 grams)

    Yep, the smallest virus would still be about twice as heavy as the cluster of antimatter atoms

  11. Re:Warp Drive by arsaspe · · Score: 5, Informative

    On second thought, anyone know if matter + antimatter actually does = lots of energy? I thought that they were going to do some kind of experiment with that but I never heard any more.

    Well, if we took .005 grammes of antimatter (quite a lot), and mixed it with the equivilant matter, we would be converting .01 grammes (.00001kg) of matter into energy,

    so If we take E=MC^2
    Where M=mass(in kg), C=speed of light (3*10^8 m/s)
    = 1*10^-5* 3*10^8 * 3*10^8
    = 1*10^-5 * 9*10^16
    = 9 * 10^11 Joules of energy

    Which is enough to light 10,000 100 watt light bulbs for about 10 days
