  • Antimatter

    How awesome is this! There's going to be some cool shit happening in the next 20 or 30 years. I for one am super excited.



    What can you do with a quarter of an hour? Write a few emails, cook rice – or store antimatter.

    The team working on the Antihydrogen Laser Physics Apparatus (ALPHA) at the CERN particle physics laboratory near Geneva, Switzerland, have stored atoms of antihydrogen for 1000 seconds – roughly 10,000 times longer than before. This should help reveal if antimatter and matter are true mirror images.

    Antihydrogen atoms are annihilated by hydrogen. The ALPHA team want to keep antimatter intact long enough to study it, so last year they worked out how to hold a cloud of antihydrogen in a magnetic trap. Not for long, though: collisions with trace gases would have either annihilated the anti-atoms or given them the energy to escape, so the team opened the trap after 170 milliseconds and observed the resulting annihilations, verifying that antimatter had been made.

    Now they have repeated the experiment, this time waiting much longer before opening the trap. They also cooled the antiprotons used to create the antihydrogen much further, which lowered the energy of the antimatter, allowed more to be squeezed into the trap and raised the chance that some would last longer (arxiv.org/abs/1104.4982).

    Antimatter's life extension will permit experiments, such as checking whether antihydrogen occupies the same energy levels as hydrogen, "perhaps within the next few years", says Daniel Kaplan of the Illinois Institute of Technology in Chicago, who is not on the ALPHA team.

    That is cool shit. I can't wait for the 2042 Suzuki powered by an anti-matter reactor that needs to be refuelled every 10 years.

    Then again, am I a fairly tragic star trek nerd.

      Very cool. Perahps we will even be able to skip fusion and go straight to antimatter power in the next 50 years. Probably complete devastation and extinction in less than 5 years after that, but those 5 years will be awesome.

        Anyone else think this sounds like ghost busters with the traps and antmatter etc etc.

          I want to know how big this "annihilation" is because the first thing that I thought of after reading that article is anti-matter warheads.

            I think you only annihilate the same mass of particles as the amount of anti-matter you have. They somehow cancel each other out. So a warhead wouldn't work really, unless you used anti oxygen to suffocate everyone or something. Patent Pending.

              thats cool, any antimatter explosions can be safely detonated above the vatican by Ewan McGregor in a chopper
              I do not mean to pry, but you don't, by any chance, happen to have six fingers on your right hand?

                I think you'll find that humans are quite proficient at finding ways of fucking each other up. If there is a way to make anti-matter shit all over another dude, it will be found.

                  Whilst it's true that only the same mass is annihilated, all of that mass is converted to energy via the relation E = mc^2. So 1kg of matter reacting with 1kg of antimatter would produce the energy roughly equivalent to 43 megatons of TNT exploding.

                      What if the energy created by antimatter vs matter collision is the sum of their mass? ie. -1 + 1 = 0?

                      If energy is measured in a degree, positive, from zero, could antimatter have a mass, equally measurable in space, as a positive but an energy the same degree of difference from zero but in the negative? Like an energy vacuum?

                          what Koola said.

                          LOLOLOLONDON.

                          Hydrogen and anti Hydrogen both have a mass of 1u.

                          1u ~ 1.66*10^-27


                          so the annihilation of 2u of mass would produce

                          2* mc^2

                          2* (1.66*10^-27)(9*10^16)

                          roughly 3*10^-10 Joules of energy

                            Since E=hf the frequency of the resulting EMR wave would be

                            f = 3*10^-10 / 6.62 *10^-34
                            = 4.5*10^23 Hz
                            = Gamma rays, Biatch!!!

                            (assuming 1 photon is created)
