Rare Particles, Matter and Anti-Matter

Observation of rare particles may shed light on why the universe has more matter than antimatter

Shortly after experiments on the Large Hadron Collider (LHC) at the CERN laboratory near Geneva, Switzerland began yielding scientific data last fall, a group of scientists led by a Syracuse University physicist became the first to observe the decays of a rare particle that was present right after the Big Bang. By studying this particle, scientists hope to solve the mystery of why the universe evolved with more matter than antimatter.

One step closer to finding the "God" particle. :)

I wonder how a universe with more antimatter than matter would look like

would we all have our noses and ears on the inside? would we fall upwards ?
or maybe it would be like in soviet russia where nobody ever did anything and the state did everything to everybody?

"oh look, there's Tomas, his bicycle is riding him" "my breakfast just had me" etc.

or maybe nothing would ever come together, just get ripped apart like large bearded men with spoons chomping down on the universal cake

ah, we are so small in the grand scheme of things...

I'm enjoying the work produced so far by CERN, but a lot of it is going off of assumptions.

We don't know for sure that the Universe is this way at all. We could just be living in a local bubble made of matter, and the rest of the Universe could be antimatter.

We don't even know for sure if what we think of as "the laws of physics" are local or homogeneous through out the Universe...

When a particle collides with its anti particle and the matter vanishes, is the energy released in the form of gamma rays?

It depends on the energy involved. High energy annihilation produces exotics, low energy annihilation produces photons (gamma radiation is really just high energy photons...)

The universe has a lot of anti-matter in it. Anti-matter has to do with the spin of the electron, not some sort of backwards world.

So... higher collision speeds = more photons emitted?

different wavelength/energy I think...
