@John ~ This should help answer your question. . . Temperature

“This time, it kept its antihydrogen cloud intact for more than 16 minutes by lowering the temperature of the antiprotons used to create the hydrogen much further, which lowered the overall energy inside their magnetic jar. The breakthrough should allow researchers to actually experiment on antihydrogen in coming years, helping them to answer some fundamental questions.

For instance, it’s unknown whether gravity affects antimatter in the same way as it affects normal matter. That is, scientists don’t even know if antimatter falls up or falls down. Having containers of the stuff to observe will naturally help scientists probe these unknowns.”

@PJ Ha and next will come anti-nuclear devices
then wat anti-world war and anti-coldwar?

Next year we will be announcing the creation of the worlds first antihydrogen bomb. Get yours while supplies last.

@7. furreal37,

Make sure to keep that away from the pasto! Should they meet, there would be a pasto-antipasto reaction and the room would disappear in a blaze of social energy and exotic appetizer particles!

Photons are their own anti-particles.

How soon before we create an anti-oxygen atom, combine it with two anti-hydrogen atoms, and get a molecule of anti-water?

Question-How could one excite anti-matter with laser beams? Wouldn’t the interaction of particles (maybe I’m thinking too much [or not enough] about wave-particle duality) simply annihilate the antimatter rather than energize it? Any clarifications would be appreciated!

whoa….way cool. cold, too.

Just to be clear, this isn’t the first experiment with antihydrogen, rather the first when they are trapped for more than a blink of an eye (of an atom). A little more and the first antispectral antilines can be experimentally measured! Yay!

seriously, seriously cool stuff
