Roundup At The Antimatter Corral

You know, I’m all for the advancement of physics research, but there’s a reason antimatter doesn’t exist in nature. It annihilates an equal amount of matter on contact and releases incredible amounts of energy.

Antimatter held for questioning

For physicists, a bit of antimatter is a precious gift indeed. By comparing matter to its counterpart, they can test fundamental symmetries that lie at the heart of the standard model of particle physics, and look for hints of new physics beyond. Yet few gifts are as tricky to wrap. Bring a particle of antimatter into contact with its matter counterpart and the two annihilate in a flash of energy.

Now a research collaboration at CERN, Europe’s particle-physics lab near Geneva, Switzerland, has managed, 38 times, to confine single antihydrogen atoms in a magnetic trap for more than 170 milliseconds. The group reported the result in Nature online on 17 November1. “We’re ecstatic. This is five years of hard work,” says Jeffrey Hangst, spokesman for the ALPHA collaboration at CERN.

An antihydrogen atom is made from a negatively charged antiproton and a positively charged positron, the antimatter counterpart of the electron. The objective — both for ALPHA and for a competing CERN experiment called ATRAP — is to compare the energy levels in antihydrogen with those of hydrogen, to confirm that antimatter particles experience the same electromagnetic forces as matter particles, a key premise of the standard model. “The goal is to study antihydrogen and you can’t do it without trapping it,” says Cliff Surko, an antimatter researcher at the University of California, San Diego. “This is really a big deal.”

So far, they’re only dealing with 38 atoms and let’s hope the scale of the research stays small. However, if they can trap and hold a tiny amount of antimatter, eventually the technology could be developed to trap and hold larger quantities and then we could be in trouble if the technology ever fell into the hands of bad actors.

The reaction of 1 kg of antimatter with 1 kg of matter would produce 1.8×1017 J (180 petajoules) of energy (by the mass-energy equivalence formula E = mc²), or the rough equivalent of 43 megatons of TNT. For comparison, Tsar Bomba, the largest nuclear weapon ever detonated, reacted an estimated yield of 50 megatons, which required the use of hundreds of kilograms of fissile material (Uranium/Plutonium).

So, How Are Those Sanctions Working Out?

I think Obama and Hillary finally have a hold of Iran by the balls this time, for sure. It won’t be long now before Iran gives up on their nuclear program and Ahmadinejad gets down on his knees and begs the West not to punish Iran anymore.

Iran increases uranium enrichment – IAEA

The International Atomic Energy Agency has said Iran has activated more equipment to enrich uranium more efficiently, violating UN resolutions.

The UN watchdog said a second set, or “cascade”, of centrifuges was operating at the Natanz pilot fuel enrichment plant when inspectors visited in July.

The move to enrich uranium to 20% purity means Iran could quickly advance to making weapons-grade material.

The West believes Iran is seeking to build a nuclear bomb. Iran denies this.

The UN Security Council, the US and EU have each imposed sanctions on the Iranian authorities to force them to halt enrichment activities.

Iran has been producing low-enriched uranium (LEU) of about 3.5% purity for some time, and announced in February that it had begun enriching uranium to 20% to make fuel for its Tehran research reactor, which produces medical isotopes. A bomb would require at least 90%.

“The IAEA can confirm that on 17 July, when agency inspectors were at [Natanz], Iran was feeding nuclear material to the two interconnected 164-machine centrifuge cascades,” spokeswoman Gill Tudor said.

Ms Tudor said the move was “contrary to UN Security Council resolutions affirming that Iran should suspend all enrichment-related activities”.

The centrifuges spin uranium hexafluoride (UF6) gas at high speeds to separate the fissile U-235 atoms from the denser U-238 atoms.

Experts say that using two interconnected cascades increases efficiency by allowing leftover LEU to be re-fed into the machines.

Once again, Iran beats us like a drum. Hey Obama, how many times does Ahmadinejad have to laugh at you and kick sand in your face before you grow a spine and take this threat seriously? It’s painfully obvious to anyone with a third grade education that your “sanctions” are worthless and unenforceable. In fact, your “sanctions” do absolutely nothing to deter Iran and serve only to make them more defiant, the exact opposite of the desired effect. You’re desperately in need of a new, adult foreign policy team that doesn’t arrive for work every day in a clown car.
