Isolation Of Antihydrogen...

  1. Wikipedia says CERN has isolated about 38 atoms of antihydrogen and maintained them for over 15 minutes? ... Do you think that is possible???

    Whenever you find a claim on wikipedia that you want to verify, follow the sources it cites. That's what they are for.
    Here, I've done it for you this time:
    http://www.bbc.co.uk/news/science-environment-13666892
    http://www.nature.com/nphys/journal/v7/n7/full/nphys2025.html
    http://adsabs.harvard.edu/abs/2010Natur.468..673A

    The last two articles are paywalled, though.

    ArXiv has got a number of papers on the subject:
    http://arxiv.org/find/all/1/all:+AND+Trapped+antihydrogen/0/1/0/all/0/1 (scroll down a bit)
     
  4. Thanks.
     
  5. Why would it be impossible?
     
  6. I thought that anti-matter couldn`t be stored inside things made of matter (its opposite) that`s why I thought it was impossible..?

    If you read the original report on CNN, the 38 atoms of anti-hydrogen were contained in a magnetic trap. These atoms were held in containment long enough for researchers to run experiments several hundred times.

    It's not impossible to make anti-matter, given sufficient time and energy; the trick is to store the stuff and keep it from reacting with matter, which is why the magnetic trap is necessary.
