Fresh analysis of LIGO data supports “no hair” theorem for black holes

Ringdown overtones yield accurate estimates of mass and spin of a new black hole.

Physicists have "heard" the telltale ring of an infant back hole for the first time, thanks to a fresh analysis of LIGO data. Researchers specifically looked for telltale "overtones" in the data from the collaboration's Nobel Prize-winning detection of two black holes merging. Not only were the overtones present, but the pattern of pitch and decay matches predictions for the black hole's mass and spin derived using the general theory of relativity. According to a new paper in Physical Review Letters, the result also supports the so-called "no hair" theorem for the classical description of black holes.

That classical picture of a black hole is a circle with a dot at the center. The circumference of the circle is the event horizon, and the dot is the singularity. General relativity holds that the area of the event horizon is a vacuum with no structure. That's because any dust, gas, or elementary particle placed at the horizon should fall into the black hole, maintaining the vacuum state. There would be no noticeable change if you threw something into a black hole—nothing that would provide a clue as to what that object might have been. It was the late physicist John Wheeler who coined the colorful description, "Black holes have no hair." (Wheeler had a knack for catchy names and phrases.) So all you need to describe black holes mathematically is their mass and their spin, plus their electric charge.

"We all expect general relativity to be correct, but this is the first time we have confirmed it in this way," said lead author Maximiliano Isi of MIT. "This is the first experimental measurement that succeeds in directly testing the no-hair theorem. It doesn't mean black holes couldn't have hair. It means the picture of black holes with no hair lives for one more day."

Feds seek to seize all profits from Snowden’s book over NDA violation

Snowden didn’t submit it to gov’t for pre-approval; DOJ says he’s in breach of contract.

The US Department of Justice may never be able to prosecute Edward Snowden for his procurement and distribution of highly classified information from the network of the National Security Agency. But DOJ lawyers have found a way to reach out and touch his income—and that of Macmillan Publishers—by filing a civil suit today against them for publication of his book, Permanent Record.

The lawsuit, filed in the US Court for the District of Eastern Virginia, does not seek to stop publication or distribution of Permanent Record. Instead, as a DOJ spokesperson said in a press release, "under well-established Supreme Court precedent [in the case] Snepp v. United States, the government seeks to recover all proceeds earned by Snowden because of his failure to submit his publication for pre-publication review in violation of his alleged contractual and fiduciary obligations."

The suit—which also names Macmillan, its Henry Holt and Company imprint, and its parent company Holtzbrinck Publishers—claims Snowden was in violation of both CIA and NSA secrecy agreements he signed as terms of his employment. In the CIA Secrecy Agreements Snowden signed, he acknowledged that "Snowden was required to submit his material for prepublication review 'prior to discussing [the work] with or showing it to anyone who is not authorized to have access to' classified information," DOJ attorneys wrote in their filing. "Snowden was also required not to 'take any steps towards public disclosure until [he] received written permission to do so from the Central Intelligence Agency.'"

EasyDNS Threatened With Criminal Complaint over ‘Pirating’ Customer

A German law firm has threatened to file a criminal complaint against domain name registrar easyDNS. The Canadian registrar refuses to hand over personal details of an allegedly copyright infringing customer without a valid court order, nor is it planning to pay the proposed €1,481 in damages and fees demanded by the law firm.

Over the past several years, the Canadian company easyDNS has come up in several piracy-related news articles.

The company’s domain registrar activities, in particular, have been a topic of discussion. Not least because it serves high-profile customers, including The Pirate Bay.

EasyDNS CEO Mark Jeftovic has always made it very clear that he doesn’t want his company to be a refuge for pirate sites. However, at the same time he is committed to protecting due process. 

This became clear a few years ago when the company refused to suspend domain names based on allegations from the City of London Police. This stance was repeated later when the RIAA asked easyDNS to suspend The Pirate Bay’s domain, which it refused to do without a court order. 

These examples show that easyDNS is no stranger to legal pressure, but a recent request from a German law firm was a bit over the top, even by easyDNS’ standards.

The company recently received a copyright notice from the German law firm Fechner Legal, ordering easyDNS to take down a URL of one of its clients who allegedly posted a copyright-infringing image. In addition, the notice came with a settlement offer, urging the registrar to pay €1,481 in damages and fees.

The letter, which was initially sent to the wrong email address years ago, came through the postal mail. EasyDNS has no plans to pay up or expose its customer, as the law firm requested. However, it did send a reply asking for a digital copy so it could be forwarded to its customer, as is standard practice.

Instead of sending over the requested digital copy, the law firm replied with a threat. Citing German jurisprudence, attorney Robert Fechner urged easyDNS to hand over the name and email address of the allegedly-infringing customer, or else.

The” or else,” in this case, would come in the form of a criminal complaint.

“If you fail to comply with the law, further proceedings will be to file a criminal complaint against you in order to acquire this information on the basis of § 14 II TMG. In this case, additional damages due to your uncooperative and unlawful behavior will be claimed.” Fechner wrote.

Despite the threat of a criminal complaint, easyDNS still doesn’t plan to hand over the name and email address of its customer. The company’s CEO stresses that it only complies with the law of the country where it’s incorporated, which is Canada.

Simply handing over personal information might violate Canadian privacy law, easyDNS stresses. This means that, if Fechner Legal wants the personal information of the customer in question, it has to obtain a valid court order, subpoena or warrant in the Province of Ontario.

“It’s almost as if Herr Fechner doesn’t understand that Canada is a completely different country than Germany, and thus businesses operating here are subject to Canadian, not German law,” Jeftovic notes.

“We have further advised Herr Fechner that both easyDNS and our lawyers take a dim view of being threatened with a criminal complaint over something like this and we wonder out loud if the German bar association would have anything to say about one of their own abusing their position and misrepresenting the law in this manner,” he adds.

In any case, it’s clear that as a third-party registrar, easyDNS isn’t going to take any action without a proper court order. This means that the allegedly infringing URL remains online for now, just like The Pirate Bay.

Dealmaster: You can still convert 3 years of Xbox Live to Game Pass Ultimate for $1

Plus Prime-only deals on a bunch of Amazon devices, Xbox One gamepads, and more.

Greetings, Arsians! The Dealmaster is back with another round of bargains to share. Today's list is headlined by a deal over at Microsoft that gets you a month of the company's Xbox Game Pass Ultimate service for $1 or two months for $2. Normally, a Game Pass Ultimate membership—which wraps Game Pass for console and PC together with Xbox Live Gold—costs $15 a month. This offer has admittedly been live for a while now, but Microsoft says the $2 deal is set to expire on September 30. (The company declined to specify when the $1 offer will end.) Plus, you could still turn the discount into an even better value with the right planning.

To explain: we noted this back when Microsoft first ran this deal earlier in the year, but when you buy Game Pass Ultimate, the company will still turn up to 36 months of existing Xbox Live Gold (or non-Ultimate Game Pass) subscription time on your account into the all-in-one membership. That means you can stock up on Xbox Live Gold first—which many Xbox players will buy anyway to play online—then add up to three years of Game Pass to that prepaid time for $1 total instead of the usual $10 (for console) or $5 (for PC) a month. Put another way: after getting three 12-month Xbox Live Gold codes for $60 each, you could get three years of Game Pass Ultimate for $181 instead of the $540 it would cost at full price. (Or two years for $121 instead of $360, one year for $61 instead of $180, etc.)

The catch is that these offers are only available to those who are new to Game Pass Ultimate, not existing subscribers. If you have a standard Game Pass subscription for console or PC, though, you can still take advantage. It's also worth noting that Game Pass Ultimate subscription time can't be reverted back to individual Xbox Live Gold or standard Game Pass subscriptions after upgrading—your account won't be locked into the Ultimate plan forever, just the prepaid time up to 36 months. But you'll have to turn off recurring billing and re-join those other services separately if you don't want to renew Game Pass Ultimate once that prepaid time expires.

Rockstar gives away a GTA classic to get you to install its new Games Launcher

How badly do you want another PC games launcher?

Right now, Rockstar is giving out a free copy of a 2004 game to entice you to install their new Rockstar Games Launcher on Windows PCs. We imagine more fare—including exclusives—will come to this storefront before long. But for now, Rockstar isn't saying.

After catching our breath and believing the fractured space of PC game launchers had calmed down for a second, yet another contender arrived on Tuesday: Rockstar Games.

The simply named Rockstar Games Launcher went live worldwide on Tuesday on Windows PCs, and it includes the ability to purchase and install a range of Rockstar-developed games (and their associated microtransactions). This is the first time Rockstar has offered direct purchases of its PC games, as opposed to serving games on services such as Steam. With that in mind, the launcher also lets players find and boot existing Rockstar games' Steam installations.

Currently, the app includes zero exclusives or apparent discounts compared to other retailers, so why should gamers install it?

AT&T supervisors encouraged sales reps to create fake DirecTV Now accounts to make the online video service seem more successful than it really was, a class-action complaint alleges.

AT&T "promot[ed] and reward[ed] account fraud" such as creating the fake accounts and signing AT&T customers up for DirecTV Now "without the customer knowing," the lawsuit claims.

The new allegations were made Friday in an amended complaint as part of a lawsuit filed against AT&T in April in US District Court for the Southern District of New York. The lawsuit alleges that AT&T lied to investors in order to hide DirecTV Now's failure.

Google Fi gets a cheaper “unlimited” plan, bundled cloud storage

With the cloud storage, you’ll save about $12 over the old Fi unlimited plan.

Google Fi gets a cheaper “unlimited” plan, bundled cloud storage

Enlarge

Google Fi, Google's MVNO (Mobile Virtual Network Operator) cellular service, is launching a second plan for users today. Besides the original pay-per-megabyte plan with unlimited calls and text, Google Fi is now launching a full blown "Unlimited" plan (with throttling after 22GB) for $70, and it comes with 100GB of cloud storage thanks to a bundled "Google One" membership.

In 2018, Google Fi introduced "Bill Protection," a tweak to the pay-per-MB plan that capped monthly bills at $80, making it an "unlimited" plan that throttled after 15GB. This new $70 plan is $10 cheaper and comes with more unthrottled data, and the bundled 100GB of Google One storage saves you another $2 a month. Google One is a monthly subscription service that gives you more storage for your Google account. Free Google accounts get 15GB across Gmail, Drive, and Google Photos, and Google One allows you to purchase anywhere from 100GB to 30TB of online storage.

The new Fi plan supports Google's family bundling, too. The unlimited plan is $70 a month for a single person, $60 a month each for two accounts ($120 total), $50 each for three accounts ($150 total) and $45 each for four accounts or more ( $180 total). With this plan, you'll get 22GB of unthrottled data and 100GB of storage per person, not shared across the whole family, which sounds like a good deal.

Video: DOD pulls plug on Boeing/Raytheon missile interceptor program

DOD takes its search for a multi-target interceptor into recompete.

SITREP: The RKV has been cancelled, meaning multi-target ballistic missile interceptors are even further off. (video link)

With North Korea throwing missiles around again and Iran continuing to depart from the nuclear framework after President Donald Trump exited the deal and re-imposed sanctions, there is as much reason as ever to be concerned about the United States' nascent anti-ballistic missile defenses. While the Missile Defense Agency's Ground-based Midcourse Defense System (GMD) and the Navy's Aegis Ballistic Missile Defense system have shown some promise in testing, there are still some weaknesses in those systems that could be exploited by an attacker—including the use of multiple decoys to soak up attempted intercepts.

That was the rationale behind the Redesigned Kill Vehicle (RKV), a $1 billion program intended to create the US military’s next ballistic missile interceptor. A joint effort by Boeing and Raytheon, RKV was supposed to give GMD the capability of engaging multiple targets with a single interceptor. The RKV was intended to build on the Exo-Atmospheric Kill Vehicle, or EKV, currently deployed as part of the Missile Defense Agency’s Ground-based Midcourse Defense System. But the RKV program has been cancelled, and the Department of Defense has put the whole program back into competitive bidding after having been placed on hold for evaluation in May by Undersecretary of Defense for Research and Engineering Michael Griffin.
