More detail on the Japanese simulation of Washington, DC.

An article on CP violation experiments, which is pretty good, but might be dated=– I thought BaBar was shut down?
-
A bit of over-enthusiastic titling– something analagous to one sort of super-symmetry might be able to be simulated in BEC’s at some point in the future.

Atomic physics experiments on chips.

“The crystalline material is called LaOFeAs comprises layers of lanthanum and oxygen sandwiched between layers of iron and arsenic — and is doped with fluoride ions. The researchers expect that the Tc of 26 K could be further increased by modifying the

“This work not only opens up the possibility of a network of satellites sending quantum encrypted messages around the world, but it should allow scientists to carry out experiments in fundamental quantum physics.”

Images, animation and graphs of yesterday’s naked-eye visible gamma-ray burst.

“He used big words,” said CNN correspondent Wolf Blitzer. “But what I don’t understand, and still find hard to believe, is that it seems like Americans actually understood those big words.”

Aw, man. I was so hoping the Swans on Tea link was about Atomic Physics experiments on snack chips…
GRB080319B – Did LIGO see anything gravitationally wavy? Super-Kamiokande anything neutrinolicious?
As for matter’s preponderance over antimatter and CP violation… Something present-day detectable must power inflation, select matter over antimatter, source left-handed weak interaction, source homochiral biology (chiral protein L-amino acids; natural D-sugars), originate in orthodox theory, not contradict prior observations, and exclude most of the 10^1000 allowable string theory vacua.
Standard Model extensions lack validation (proton decay half-life and Super-Kamiokande; CAST and solar axions). Perturbation and Yukawa potential techniques are sour jokes. Equivalence Principle and Lorentz Invariance violation attempts are sterile. Quantized gravitations are disasters.
Dump pseudo-Riemannian spacetime V^4. Use Weitzenböck spacetime A^4 with spacetime torsion. It has a teleparallel gravitational energy-momentum pseudotensor anti-symmetric to parity transformation. It supports a pseudoscalar chiral vacuum background.
1) Only opposite parity mass configuration is interactive – no contradictions of prior observations, especially massless EM,

Exquisite bounds
2) Chiral asymmetries are naturally sourced.
3) Chiral vacuum background is detected va unremarkable parity Eötvös and parity caloritmetry experiments (not PVED experiments).
4) Somebdy should look. Don’t send a particle in to do a field’s work.
