Researchers at CERN have created and trapped antihydrogen in an attempt to study the underpinnings of the standard model of physics. Antihydrogen is made of antiparticles, specifically an antiproton and a positron, instead of the proton and an electron that are present in natural hydrogen. It has the same mass but opposite charge of its normal matter counterparts.

Antimatter has a bad reputation for being dangerous because it annihilates on contact with regular matter, releasing prodigious amounts of energy. However, the clever Ars reader will note that they have not been annihilated by the antimatter produced at CERN. The reality is that if you gathered all of the antimatter CERN has ever created, you wouldn't garner enough energy to power your laptop through reading this article. //

Antiparticles behave predictably in the presence of electric or magnetic fields and so can be contained in a special magnetic container called a Penning trap. Antihydrogen, which has no net electric charge, is much harder to contain. //

The ALPHA trap can confine antihydrogen in the ground state if it's kept at temperatures of less than half a Kelvin.

One challenge of this experiment is mixing the antiprotons and positrons at relatively low velocities such that antihydrogen can form efficiently. The efficiency is relative; The authors had to mix 10 million positrons with 700 million antiprotons in order to get get 38 certifiable antihydrogen events. //

It remains one of the largest unsolved problems in physics today as to why the Universe contains more regular matter than antimatter. Symmetry would suggest the Universe should have produced equal parts matter and antimatter, which would have annihilated—because we are here, we know this was not the case. Now that they have a bit of antihydrogen on hand, the researchers will test fundamental symmetries in nature (charge conjugation/parity/time reversal) by examining the excited states of antihydrogen. //

When can we start weaponizing it?
As soon as we have significant amounts, and apparently figure out how to stabilize it enough to mix with matter.

1kg antimatter mixing with 1kg matter yields something like 50 megatons. (Which means that a 3oz bottle of antiperspirant is about 4 megatons. Now TSA's really going to have an aneurysm. </rimshot>) //

It's not that big a deal; sniffer dogs would pick out the matching 3oz bottle of perspirant pretty easily.

This is a victory not just for my constituents, but for the Constitution itself. The Supreme Court has affirmed what should NEVER have been in question — that no state legislature has the power to silence an elected official simply for speaking truthfully about issues that matter. //

In her dissent, Justice Jackson argued that intervention by SCOTUS would be premature. Wrote Jackson: "Why would any applicant who thinks the lower courts are mistaken wait for those courts’ final word on an issue if real-time error correction via our emergency docket is readily available?” //

Jackson may not understand "irreparable harm". The longer Libby waits for relief, the more votes she misses. Doesn't seem like a difficult concept.

Many Americans, bathed in the myth of Zelensky as Ukraine’s George Washington, would be surprised to know that unlike Washington, who rejected the monarch’s crown at the end of the American Revolution, and who on his own accord returned to his farm after two terms as president, is now entering his second year after his term was supposed to expire.

Zelensky was sworn in on May 20, 2019, for a five-year term that should have expired 12 months ago. He signed a 90-day martial order Feb. 24, 2022, after it was passed by the Rada, our parliament, with provisions for almost automatic renewals. After Zelensky’s term expired, the Rada is now voting to renew martial law every 90 days.

We have had war in Ukraine since 2014, but there was never martial law until Zelensky and his crew took a chance and got away with it. //

Americans are told Zelensky’s term was extended by the Ukrainian Constitution because the country was at war, but the record shows that martial law is a legislative action, renewed every quarter with Zelensky’s signature.

In addition to suspending elections, subsequent amendments to the martial order have put all media under the Kiev government’s control and the outlawing of nearly a dozen opposition parties, including the Opposition Platform-For Life Party, the second largest bloc in the Rada.
American presidents never suspended elections during war

The contrast with the American experience is instructive here. In the War of 1812, President James Madison saw the British burn the White House, among other humiliations, but he did not suspend elections, seize the printing presses or outlaw the Federalist Party.

Presidents Abraham Lincoln, fighting the Civil War; Woodrow Wilson, fighting World War I; and Franklin Roosevelt, fighting World War II, all curtailed civil rights and restricted the media.

Yet, the elections went forward, even with the government facilitating the ballots for millions of soldiers mobilized far away from home. //

The Ukrainian Civil War has brought death and destruction to my country, but for one man alone, it has brought glory and power.

Every day, Zelensky keeps the war going to preserve that glory and power, the suffering continues, and he mocks Washington as a fool for peacefully returning to Mount Vernon.

Sergii Nosenko was a 2019 candidate for Ukrainian president. He lives in the United States with his author wife Daria and their children to avoid the clampdown on President Volodymyr Zelensky's political critics. //

And that election will be fraught with danger for Ukraine and Europe. Putin will be working hard to ensure that someone friendly to him gets elected. If that happens Ukraine will go right back to where it was headed before the Orange Revolution. Perhaps the near-inevitable removal of Donbass from the electorate will tilt things strongly to an independence-minded candidate, but I wouldn't count on it.

The length's the Democrats went to in order to cover up Biden's various ailments is wild, but their willingness to believe their own lies is, in my opinion, even wilder.

But this is what the tribe requires. You cannot give the truth any quarter, even if it's standing there in broad daylight. You must embrace the lie, even at the cost of your own integrity and reputation. This is the tribal law of the left.

Embrace the lie until it becomes truth, no matter how long it takes for that transformation to happen.

This is one of the reasons the legacy media is in such dire straits. Thanks to various internet websites like X, Rumble, and even YouTube, the truth is far more visible than it's been in the past. The shelf-life of the lie is much smaller than it used to be, yet the tribal law of the left doesn't allow for this to be recognized. They'll stare you straight in the face and tell you the sky is green as you sit under a baby-blue, cloudless day, and when you tell them to look up, they'll look at you like you're stupid in hopes you'll start feeling that way.

But fewer and fewer people are starting to feel the pressure they once were capable of exerting.

"We got the Olympics and then we got, through Johnny... we got the World Cup. We got them both. And I said, man, I won't be president! I got the Olympics and the World Cup [2026], and I won't be president, and they're gonna forget that I got them, nobody's gonna mention it, because you know, that's the way life is.

"And then they rigged the election. And then I said, 'You know what I'll do? I'll run again, and I'll shove it up their a*s.' And that's what I did. And all of a sudden, I then realized, I said, you know what? I got the Olympics. I got the World Cup, and I got the 250th. Look at the way this works out.

"So if they would have left us alone and wouldn't have cheated on the election and wouldn't have rigged it, I would have been retired right now. I would have been happily doing something else. And instead, they have me for four more years. Can you believe it?"

Once Essayli and Co. have determined that someone has committed a felony by re-entering the country, the whole game changes:

As soon as the task force ID's an alien booked into a local jail who has a previous deportation, they seek a federal criminal warrant on them for felony re-entry, signed off on by a federal judge.

Unlike an administrative ICE warrant or ICE detainer request, these criminal judicial warrants for 8 USC 1326 CANNOT be ignored by sanctuary jurisdictions, and California's sanctuary state law cannot shield aliens from these criminal warrants. Instead of releasing the alien inmates and ignoring ICE detainers, jails must hand the aliens over to the Feds, regardless of sanctuary policy.

Alice Marie Johnson, a 69-yr old grandmother, had her life sentence for a nonviolent drug trafficking offense commuted by Trump in 2018 after serving 21 years. Trump made her Pardon Czar Feb.2025.

"I had appealed to President Obama 3 times and had been turned down all 3 times."

11:34 PM · May 18, 2025 //

In addition to finding those people who deserve a second chance, Johnson wants part of her job to be to push for possibly outdated and antiquated laws that need to be changed. She also pointed out the fact that many people who don't have the money to navigate through the justice system are often caught in it, ... //

Johnson said she feels like she represents hope for those who may be in the same situation, and that "they will not be defined by the worst thing they have done in their lives." Lara Trump asked Johnson, "Would your story have been possible in any other country?"

Without hesitation, Johnson replied, "No, absolutely not. Only someone like President Trump could make my story possible."

Alice Marie Johnson summed up her life story with an undeniable truth: "I represent what America is all about: second chances..."

“These are people that, on the basis of their race, are having their properties taken away from them and their lives are being threatened and in some cases k*lled."

Why can't we just quote the text of our own law on asylum? That is:

8 U.S. Code § 1158 - Asylum
(B) Burden of proof
(i) In general

The burden of proof is on the applicant to establish that the applicant is a refugee, within the meaning of section 1101(a)(42)(A) of this title. To establish that the applicant is a refugee within the meaning of such section, the applicant must establish that race, religion, nationality, membership in a particular social group, or political opinion was or will be at least one central reason for persecuting the applicant.

There are few people admitted to this country in the last 40 years that satisfy the letter of the US' asylum law, the S. African people are surely qualified to make that claim. Whilst, people that are fleeing poverty, crime, or just a bad marriage or their mother-in-laws don't qualify for asylum.

I reported how Pope Leo XIV greeted Vice President JD Vance and Secretary of State Marco Rubio after the Pope's inaugural Mass on Sunday. It was also interesting to see the Pope's brother sitting right next to Vance and his wife in the American delegation during the mass.

To use the heating BTU calculator, you will first need to measure the place you want to heat up. You need to know if you’re heating up a 1000 sq ft, 1500 sq ft, or a 3000 sq ft home, or a 400 sq ft room, for example.

Secondly, you need to figure out what climate zone you live in. That will determine how many BTU per square foot you need for heating (more on that later on). The United States is divided into 7 main climate zones or regions. Example: Miami, Florida, is in Climate Zone 2 and requires 35 BTU of heat per sq ft. Chicago, Illinois, is in Climate Zone 5 and requires 50 BTUs of heat per square foot.

https://basc.pnnl.gov/images/iecc-climate-zone-map

Climate Zone BTUs Per Sq Ft
Climate Zone 1 30 BTU per sq ft
Climate Zone 2 35 BTU per sq ft
Climate Zone 3 40 BTU per sq ft
Climate Zone 4 45 BTU per sq ft
Climate Zone 5 50 BTU per sq ft
Climate Zone 6 55 BTU per sq ft
Climate Zone 7 60 BTU per sq ft

We presuppose the standard ceiling height of 8 ft. For every additional ft above 8 ft, you need to add 12.5%. So, for 9 ft ceiling, you need to multiply the BTUs by 1.125 to get the most adequate estimation.

A castle doctrine is a self-defense law that states that a person’s home (sometimes also a place of work or vehicle) is a place that grants one protection and immunity from prosecution in certain circumstances to use force or deadly force to defend oneself against an intruder. There is no duty to retreat from the situation in one’s home (or workplace or vehicle if applicable) before using force, but there may be a duty to retreat in a public place.

The United States has two different self-defense laws. The “Stand Your Ground” Law states that there is no duty to retreat from the situation before using deadly force and is not limited to one’s home, place of work, or vehicle. The “Duty to Retreat” Law states that one cannot harm another in self-defense when it is possible to retreat from a threatening situation to a place of safety. In all duty-to-retreat states, the duty to retreat does not apply when the defender is in their own home. States may have both a Castle Doctrine and a Stand Your Ground variation, such as Iowa.

An Oklahoma law now makes it legally clear you can point or intimidate an individual with a weapon if you are defending your home, private property, or business.

Governor Kevin Stitt signed House Bill 2818 on Thursday, which went into effect immediately. Oklahoma already has “stand your ground” laws when it comes to protecting your life, but language in the bill now expands to your property as well. //

Every year, armed citizens prevent crimes and shootings, sometimes even by simply brandishing their weapons. Several studies have shown that armed citizens actually have a better record of resolution in shooting incidents than police officers, and in every state that keeps records, armed citizens have a lower rate of "bad" shoots or injuries in shooting events than police officers. Not to mention that self-defense is a basic, natural right, and firearms are the most effective way to defend oneself.

As of this writing, there are 45 states that have some form or another of "Castle Doctrine" laws, and 18 "Stand Your Ground states", with a fair amount (obviously) of overlap. Twenty-nine states are now "Constitutional Carry" states, in which citizens may carry, concealed, any firearm they may legally own.

So this is another performance about concerns they allegedly have for family life, but if you had read the Heritage Foundation’s Project 2025, despite Trump saying he knew nothing about it, if you had read it, it's all in there. It's all in there. Return to the family, the nuclear family, return to being a Christian nation, return to producing a lot of children -- which is sort of odd because the people who produce the most children in our country are immigrants, and they want to deport them. //

So none of this adds up, but, you know, one of the reasons why our economy did so much better than comparable advanced economies across the world is because we actually had a replenishment, because we had a lot of immigrants, legally and undocumented, who had a, you know, larger than normal by American standards, families. So this is just another one of their, you know, make America great again by returning to the lifestyles and the economic arrangements of not just the 1950s. I mean, let's keep going back as far as we can. And, you know, see what happens. //

As the Federal Communications Commission considers GPS alternatives, SpaceX says its Starlink satellites are already up for the task.

The company made its pitch in a Wednesday letter to the FCC after the commission kicked off a public inquiry about developing alternatives to GPS, which has long been run through a single provider, the US Defense Department.

The FCC’s goal is to usher in Positioning, Navigation, and Timing (PNT) solutions to complement GPS. In response, SpaceX sent a five-page letter that noted: "One opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit ('LEO') satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity.”

But this week, Yuval Raphael walked the welcoming carpet at the opening of the Eurovision contest in Basel, Switzerland. Raphael is Israel’s contestant in the competition. Because she is from the Jewish state, the normal fans cheering her were joined by keffiyeh-clad protesters waving Palestinian flags, one of whom made a throat-slitting gesture as Raphael’s delegation went by. He stepped toward the Israelis and spat at them.

Now, Israelis are quite used to getting random death threats from cosplaying revolutionaries comfortably ensconced in their flats thousands of miles from the conflict zone. Yuval Raphael just smiled and waved, and at one point made a heart gesture with her hands. That’s pretty much how it goes—Israeli hearts and Palestinian neck-slicing; they’re partners in a familiar dance.

But there is more to the story when it comes to Raphael. She is a survivor of the Nova massacre, the largest mass killing at a music festival in history. Her story is harrowing, and her appearance at Eurovision is, frankly, an inspiring if not historic moment for music fans everywhere. //

European broadcasters tried to get Raphael disqualified from the contest entirely, on account of her national origin.

Weber ultimately underwent the procedure. She said she wanted readers to know that the state’s pro-life law was “so dangerous for women.” But in reality, assuming her account is accurate — if it’s true that doctors refused to perform a lifesaving medical procedure because of the state’s pro-life law — the entire ordeal doesn’t prove anything other than that some doctors are incompetent and don’t know how to navigate relatively simple state laws.

The facts are these: the South Carolina “heartbeat bill” explicitly spells out that a doctor can perform an abortion if he determines “that a medical emergency exists or is performed to prevent the death of the pregnant woman.” For good measure, the law directly states that both “intrauterine fetal demise” and “miscarriage” constitute a medical emergency that can justify an abortion.

This is the substance of the law. There are no gimmicks or hidden rules. By her own account there was absolutely no reason that Elisabeth Weber should not have received a D&C. The problem was not with state law, but with the doctors who were either too ignorant or too risk-averse (or both) to do proper medicine.

This is and always has been untrue; Every pro-life law in the United States, without exception, contains provisions that allow for emergency medical intervention to save a mother’s life. //

Doctors are forbidden from killing an unborn child in an act of abortion, but they are more than able to perform related procedures that can save a mother’s life (all the more so in tragic cases like Weber’s, where the baby has died, or even in Thurman’s case, where the babies were killed).

We should never fall for this type of misdirection. Abortion advocates who claim that such laws forbid doctors from saving the lives of women should point to the specific part of the law they claim makes this so.

It is strongly within the national interest to help parents act on their preferences, because research shows secular schooling is the No. 1 factor causing Americans to lose their faith. People who love America cannot be neutral about that, because widespread Christianity is essential to keep what’s left of our constitutional way of life. The American Founders believed this fervently, and it is true.

The truth is, the secular indoctrination factories that judges forced all public schools to become are the prime engine of America’s decline. For one thing, the loss of faith is the entire cause of our fertility crisis, a key component of our entitlement spending crisis. Keep more Americans Christian, and entitlement programs become much better funded.

For another thing, identity politics is an anti-reason, anti-thought, anti-human, anti-God philosophy, and it controls public education today from top to bottom. So secular schooling is not just a top driver of America’s intellectual corruption — although it is that! — but also of our moral corruption.

That is the underlying cause of all of our nation’s many co-morbid existential crises, including the fact that Congress can’t cut insanely corrupt and existentially threatening spending. So it’s more important to address the underlying cause than its symptoms. Funding school choice does exactly that. //

A Free Society Requires Christian Education

In order for government not to micromanage people and thereby eventually become dictatorial and totalitarian, citizens must responsibly manage their lives. If people do not restrain and order their private lives, eventually government must do it for them. Everyone from James Madison to Alexis de Tocqueville knew and preached this. //

The top two places people learn the virtues, or the art of self-governance, are in church and at home. These two institutions do in a nuanced and non-coercive way what government does bluntly and coercively: instruct and encourage people in the art of making morally responsible choices each week, day, and hour.

That’s why there is no such thing as a free society without widespread Christianity, as even professional atheists now acknowledge after spending their lives working to destroy it. And that’s why even people who aren’t Christians should support school choice if they want to live in a free society. Obviously, Christians should also support Christian education as a moral imperative, which is why historically churches have always operated schools. //

Everyone who isn’t insane wants to live in a society where children and adults learn not to steal, kill, cheat, and self-destruct. Christianity teaches this without needing any expenditure of taxpayer funds. There are lots of other reasons, too, for a purely rational vote for school choice, including that private schooling costs taxpayers far less while returning far better results than public schooling.

An America without Christianity is not America at all. That is why cultural Marxists treat Christianity as their No. 1 enemy — because it is. And as everyone in the age of woke should be aware, controlling schooling is one of their chief national destruction strategies.

So fighting the left’s destruction of education is a radically good and necessary action. School choice is the prime means of making America competent, solvent, and faithful again, and that’s why it may be the most important budget provision Congress can pass.
