Summary: Remember when this blog started and I tried to keep it focused solely on antimatter? That turned out to be too specific but I am once again able to get back to the heart of this blog. While not and advancement in antimatter studies, this is a recent article on ten facts you may not have known about antimatter. Contained within the article are helpful links to more topics related to antimatter that can quench your thirst for knowledge. Enjoy.

Two New Particles
Summary: You read that correctly. Amid all the excitement about the comet landing, researchers at CERN have detected two new particles with the LHCb experiment. These particles were predicted to exist by the quark model but had never been observed. And now we are pleased to introduce yo to Xi_b' and Xi_b*. Super exciting names I know but maybe they will become fancier in the future.
Both of these particles contain one beauty quark, one strange quark, and one down quark. They are more than six times as massive as the proton. They have different spins (a weird quantum mechanical property that describes their angular momentum).
So this is super exciting, because finding more proof for your theories is always good. And now I am off to find out why I have never heard of a beauty quark before. UPDATE: Apparently it is another name for the bottom quark.

Cosmic Waves of Discovery
Summary: Scientists at the BICEP2 collaboration at the South Pole have detected signal that confirm theories of the rapid expansion of the universe immediately after the big bang. If validated by other experiments (which is likely to happen as the signal found is actually stronger than predicted) this confirms a super-rapid expansion within the first instants of the universe before "slowing down" to rapid expansion. What they found were twists in Cosmic Radiation Background that could have only been produced by gravitational waves.
So what does this mean? These signals tell astronomers that gravity was present during this time in which quantum effects dominated the, then very tiny, universe. This gives us greater hope that the Four Fundamental Forces can be one day combined into a unified Theory of Everything which could better describe conditions at the big bang.
