Hints of new dark force seen in galactic smash-ups

Colliding clusters of galaxies may hold clues to a mysterious dark force at work in the universe. This force would act only on invisible dark matter, the enigmatic stuff that makes up 86 per cent of the mass in the universe.

Dark matter famously refuses to interact with ordinary matter except via gravity, so theorists had assumed that its particles would be just as aloof with each other. But new observations suggest that dark matter interacts significantly with itself, while leaving regular matter out of the conversation.

"There could be a whole class of dark particles that don't interact with normal matter but do interact with themselves," says James Bullock of the University of California, Irvine. "Dark matter could be doing all sorts of interesting things, and we'd never know."

Some of the best evidence for dark matter's existence came from the Bullet cluster, a smash-up in which a small galaxy cluster plunged through a larger one about 100 million years ago. Separated by hundreds of light years, the individual galaxies sailed right past each other, and the two clusters parted ways. But intergalactic gas collided and pooled on the trailing ends of each cluster.

Mass maps of the Bullet cluster showed that dark matter stayed in line with the galaxies instead of pooling with the gas, proving that it can separate from ordinary matter. This also hinted that dark matter wasn't interacting with itself, and was affected by gravity alone.

Musket shot

Last year William Dawson of the University of California, Davis and colleagues found an older set of clusters seen about 700 million years after their collision. Nicknamed the Musket Ball cluster, this smash-up told a different tale. When Dawson's team analysed the concentration of matter in the Musket Ball, they found that galaxies are separated from dark matter by about 19,000 light years.

"The galaxies outrun the dark matter. That's what creates the offset," Dawson said. "This is fitting that picture of self-interacting dark matter." If dark matter particles do interact, perhaps via a dark force, they would slow down like the gas.

This new picture could solve some outstanding mysteries in cosmology, Dawson said this week during a meeting of the American Astronomical Society in Long Beach, California. Non-interacting dark matter should sink to the cores of star clusters and dwarf galaxies, but observations show that it is more evenly distributed. If it interacts with itself, it could puff up and spread outward like a gas.

So why doesn't the Bullet cluster show the same separation between dark matter and galaxies? Dawson thinks it's a question of age – dark matter in the younger Bullet simply hasn't had time to separate.

New window

The idea complements a previous study that saw evidence for dark forces at work in the Bullet cluster. In 2007 Glennys Farrar of New York University and colleagues said that the smaller cluster was moving too fast for gravity alone to be responsible. They suggested that some mysterious force related to dark matter might be hurrying it along.

Still, two clusters is not a lot to go on. Dawson, Bullock and colleagues are following up with about 20 more galactic collisions to see if they show any unusual behaviours. "I really think that we're almost to the point where we have enough observational data in hand," Dawson said. "We could close the book on self-interacting dark matter."

If the new force does exist, we might soon be able to see its effects on things influenced by dark matter, such as the behavior of black holes or the masses of the first stars, says Douglas Finkbeiner of Harvard University in Cambridge, Massachusetts, who was not involved in the new study.

"The simple thing isn't always the right thing, so I really appreciate that Will is trying to look into these other possibilities," he says.

Louis Strigari of Stanford University in California agrees. "Self-interacting dark matter is worth pursuing because we're still very ignorant," he said. "We're desperate to understand what dark matter is, so any new window is welcome."

Latino should have played lead in 'Argo'

Ben Affleck plays the lead role of Tony Mendez in "Argo," which he also directed.

STORY HIGHLIGHTS

• Oscar nominations on Thursday, and Ben Affleck expected to get one for "Argo"


• Affleck plays real-life Latino who helped diplomats escape in Iran hostage crisis


• Ruben Navarrette: Affleck should have used a Latino actor to play role


• He says it cheats actor out of a job, and the Latino community out of a hero's story

San Diego, California (CNN) -- The upcoming Oscars are no stranger to causes or controversy. And this year, there is a strong dose of both surrounding the film "Argo" -- and its star and director, Ben Affleck.

This controversy bubbled up when the buzz started that Affleck could get an Academy Award nomination for best director when the announcements are made Thursday.

"Argo" tells how an ingenious and daring CIA agent helped orchestrate the rescue of six U.S. diplomats from Tehran during the Iran hostage crisis of 1979-1980. In November 1979, about 300 Islamic students stormed the U.S. Embassy and 66 Americans were taken hostage. But six U.S. diplomats escaped and were hidden at the Canadian Embassy by the Canadian ambassador and his wife.

Ruben Navarrette Jr.

The CIA agent -- Antonio "Tony" Mendez, played by Affleck -- successfully led the mission to evacuate the Americans, which involved Mendez and his associates posing as a Canadian film crew that was eager to make a movie in Iran.

The real Tony Mendez was awarded the Intelligence Star for Valor, and other honors, for leading the rescue. He later wrote a memoir, detailing the events in Tehran.

"Argo" is loosely based on Mendez's book. Better make that, very loosely based. As movie critics and others have pointed out since the movie opened a few months ago, the filmmakers took lots of dramatic license with the story. Mendez's role is played up, while that of the Canadians who helped hide and protect the Americans is played down. Some scenes depicted in the film never happened. Some characters are composites of several real people.

In other words, it's what you would expect from a Hollywood feature film based on a historical event. It's not a documentary. It's meant to be taken with a grain of salt, and to be entertaining.

Still, there are some Latinos -- in and out of Hollywood -- who think that, in this case, the filmmakers, and especially Affleck, pushed the concept of creativity too far. They say Affleck missed an opportunity to put more Latinos on screen. Moreover, they say, Affleck improperly claimed, for himself, the choice role of Mendez when he should have cast a Latino actor instead. They insist that the director didn't just cheat a Latino out of an acting job but the Latino community out of a feel-good story about one of their own who won acclaim for a heroic deed.

The critics are right, and their cause is just. Affleck should have tried to cast a Latino to play Mendez. That's common sense, and it would have made "Argo" a better movie. Affleck also didn't do himself any favors by trying to dismiss the criticism with a glib remark that essentially said that it really doesn't matter that the actor playing Mendez isn't Latino since Mendez himself isn't, shall we say, overtly Latino.

At a recent forum intended to publicize the film, Affleck responded to a question from the audience about the controversy by noting that "Tony does not have, I don't know what you would say, a Latin/Spanish accent" and that "You wouldn't necessarily select him out of a line of 10 people and go 'This guy's Latino.' "

Ouch. At least Affleck didn't slip and say "line up."

"So I didn't feel as though I was violating something," he said, "where, here's this guy who's clearly ethnic in some way and it's sort of being whitewashed by Ben Affleck the actor."

Johnny Depp set a better example. Several months ago, Depp turned down the role of Mexican revolutionary Francisco "Pancho" Villa in another film. He said that the role should go to a Latino. I praised Depp at the time for showing that, besides being a great actor, he is also a person of character.

The exclusion of Latinos from Hollywood is an old story. This is still a black and white world, where Latinos rarely get cast in the leading role. We're the gardeners and housekeepers, the gang leader and drug dealers, the nannies and farm workers. That's it. There has been some progress, of course. But not enough -- not when you have a Latina in the Supreme Court, three Latinos in the U.S. Senate, and Latinos heading Fortune 500 companies.

I could blame the environment of Southern California, in which most Hollywood writers, producers and directors live and spend most of their time. When they get up in the morning and drive to work, most Latinos they encounter are subservient. We clean their homes, cook their breakfast, trim their hedges, park their cars and otherwise help them get through the day.

Still, you can push this argument too far, and wind up going down a dangerous path -- one that ultimately sets back the greater cause of trying to get television networks and film studios to create a broader range of meatier roles for Latino actors and actresses.

After all, it's a short walk from saying that a director should have cast a Latino to play a Latino to arguing that only Latinos can play Latinos. And, if that's the argument, then on what moral high ground do Latinos stand to also push -- as we should -- for Latino actors and actresses to be considered for generic and mainstream roles that could have gone to white actors? We can't have it both ways.

Even if Latinos succeed in making their point about this one director and this one movie, it could backfire. We could win this battle, and still lose the war.

But before Latinos can be fully integrated into America and not considered outsiders, we have to take every opportunity to push for inclusion and fairness. And acknowledging that Latinos have the skills to play themselves is a good start.

Leaked video shows teens joking about Ohio rape case

The threats are part of a series of online messages that have targeted individuals and authorities in Steubenville amid increased attention over two high school football players who are facing rape charges.

Jefferson County Sheriff Fred Abdalla said Wednesday he'd provided the FBI a copy of an anonymous Facebook post in which someone threatened to kill his family.

Steubenville Police Chief William McCafferty said he gave the FBI an email that he had opened Wednesday morning, which then disabled his computer.

FBI spokesman Todd Lindgren said he could not immediately comment.

The two teenage boys are set for trial next month in juvenile court on charges they raped a 16-year-old in August. Their attorneys have denied the charges in court.

Much of the evidence in the case played out on social media, in which the photos of the seemingly unconscious girl were posted online. A video published and then deleted from YouTube shows a third freshman, Michael Nodianos, joking about the alleged rape.

The hacking collective Anonymous has staged rallies in support of the alleged victim, and hackers were able to dig up and re-post the deleted YouTube video online.

According to the Steubenville Herald Star, Nodianos' attorney said someone hacked into his client's email and social media accounts, as well as the email accounts of his family members. He has since dropped out of Ohio State University, where he was slated to attend on a scholarship.

Arias Caught Lying to Cops in Recorded Phone Calls

Jodi Arias blatantly lied to police who asked her about Travis Alexander's death, telling them in recorded phone calls that she kept trying to call and message Alexander the week of his death but never heard back from him.

The phone calls were played as evidence during the fourth day of Arias' trial, in which she is charged with murder and could face the death penalty if convicted of killing Alexander in a "depraved and heinous" way. Arias has admitted to killing her former boyfriend, but claims it was self-defense.

During the phone conversations played in court, Arias can be heard telling Mesa, Ariz., detective Esteban Flores that she last talked to Alexander on Tuesday night, June 3, 2008, around 10 p.m. She had been in Los Angeles, about to leave to go to Utah to visit a new love interest, she said.

After June 3, he stopped calling her back, she said.

Photos of Key Players and Evidence in the Jodi Arias Murder Trial

"On Tuesday night (I talked to him), it was brief though, 10 o'clock maybe. I'd say 10 p.m. or 9 - 9:30. I was calling people because I was bored on the road. He was nice and cordial, but kind of acting like he had hurt feelings," she said.

"I may have called him Wednesday, from the road, and I sent him a couple of text messages, and a couple of pictures," she said, though Alexander didn't pick up and his voice mailbox was full. "That's unusual. He deletes all of his messages. I didn't want to be obsessive about it because we're not together anymore and I didn't like to call too much."

According to court records, Arias, 32, actually went to Alexander's home on in Mesa on Wednesday morning. There, the pair had sex and took graphic photos of one another with Alexander's camera.

Then, Arias is believed to have killed Alexander, 30, in his shower by stabbing him, slashing his throat from ear to ear, and shooting him in the head.

In the phone conversations, Arias told Flores that she considered calling Alexander's friends when he stopped returning her calls on Wednesday, but didn't want to act like "his mother."

Alexander's friends found his body five days later with stab wounds and a bullet wound, lying in blood in his home.

Flores asked Arias if she ever considered buying a gun, she said she was too scared of handguns.

"I've looked into handguns. I have a list of things I'm scared of that I'm trying to overcome," she said. "I got that from Travis, you know, to push yourself out of your comfort zone, and do things you're afraid of. But handguns are expensive and not really in my price range right now."

Arias is accused of stealing her grandmother's handgun and using it to shoot Alexander in the head during the attack.
The detective interviewed Arias by phone multiple times in June after Alexander's body was discovered by his friends on June 9.

Arias was indicted on July 9, 2008, and changed her story again before her arraignment, telling a TV news station that she was at Alexander's house when he was killed and witnessed two intruders kill him.

After she was arraigned, Arias told police she killed Alexander, but did it in self-defense. Arias's attorneys have said that Alexander was controlling and abusive toward Arias, and described him as a "sexual deviant."

In earlier testimony in court today, Arias's new love interest, Ryan Burns, testified that Arias showed up to his house on the morning of Thursday, Dec. 5, just 24 hours after she killed Alexander.

There, the pair cuddled, kissed, and watched movies, according to Burns.

Burns, who met Arias at a business conference in spring, 2008, said he exchanged frequent long phone calls and online conversations with Arias before inviting her to come visit him in West Jordan, Utah, in June. Arias lived in California at the time.

She arrived at Burns's home 24 hours after she was expected there, telling him that she got lost, drove the wrong way on a freeway for a few hours, fell asleep for awhile, and then got lost again, Burns testified today.

She never told him that she had confronted Alexander with a knife or gun and ended up killing him just hours before their date.

When she arrived, the pair quickly got physical, he testified.

"We went back to my house. We talked for awhile, and agreed that we were going to watch a movie. At some point we were talking and we kissed. Every time we started kissing it got a little more escalated. Our clothes never came off, but at some point she was kissing my neck, I was kissing hers, but our clothes never came off," he said.

Burns said that both he and Arias stopped kissing at the time, though they again became physically involved later in the evening when Arias climbed on top of Burns and began kissing him. Burns said that they stopped kissing because he did not want her to "regret the visit" because of her Mormon beliefs about sex.

He also told prosecutors upon questioning that Arias was physically strong.

"She's very fit," he said, describing their encounter when she climbed on top of him. "She's very strong. She has close to a six pack (of abs)."

Prosecutors likely asked about the strength of Arias because in testimony Tuesday Maricopa County medical examiner Kevin Horn said Alexander was stabbed so forcefully that the blade chipped his skull and his neck was cut all the way back to the spinal cord.

Burns, who is also a Mormon, said he noticed two bandages on Arias's hand when she arrived at his house, which she told him she got when a glass broke at her place of employment, Margaritaville.

During her visit, the pair also went to a business meeting and went out with Burns' friends where Burns described Arias as acting "shy" and a "little awkward."

"She was fine, she was laughing about simple little things like any other person. I never once felt like anything was wrong during the day. With a crowd she was a little awkward in social areas, but one on one she was very talkative and excitable," he said.

Pruney fingers give us better grip underwater

WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.

Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.

To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.

With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.

So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Japan plans US$2.1b military spend in stimulus package: official

TOKYO: Japan plans to spend $2.1 billion on its military over the next few months as part of a huge stimulus package, a defence ministry official said Wednesday, amid growing concerns over a rising China.

The cash is in addition to the regular military spending for 2012-13 and is separate from a boosted budget request for next fiscal year that ruling party policy makers called for on Tuesday.

"We will request 180.5 billion yen to be allocated to military spending from a stimulus package," a defence ministry spokesman told AFP, adding that some of the cash will be used to buy PAC-3 surface-to-air anti-ballistic missile systems and modernise four F-15 fighter jets.

The request for funds has to be approved by the finance ministry before being officially included in the stimulus the government is set to announce later this month, reportedly worth 13.1 trillion yen for this fiscal year to March.

The announcement came a day after Prime Minister Shinzo Abe's ruling Liberal Democratic Party said Japan will increase military spending for the first time in 11 years next fiscal year starting from April.

Japan is involved in a territorial tussle with China over a group of uninhabited islands in the East China Sea. Beijing has sent vessels to the area dozens of times and late last year dispatched a plane.

Nerves in Tokyo have also been rattled by an unpredictable North Korea. It sent a rocket over Japan's southern islands last month in what it insisted was a satellite launch. Tokyo and its allies said the launch was a covert ballistic missile test.

"Out of 180.5 billion yen, the defence ministry plans to use 60.5 billion yen to prepare for the changing security environment surrounding Japan," the spokesman said.

The defence ministry also plans to purchase three SH-60K patrol helicopters and to add a battery for an intermediate-range ballistic missile system, he said.

"We need to update our equipment as the security environment surrounding Japan is becoming harsher as North Korea has test-launched missiles twice in the last year and tensions with China continue," he said.

Under usual precedent, 70-80 percent of a defence order must be spent with domestic firms, although this is not a legal requirement, he said.

Opinion: Time for tough talk with Karzai

The last time Presidents Obama and Karzai met was in May in Kabul, when they signed a pact regarding U.S. troop withdrawal.

STORY HIGHLIGHTS

• Afghan President Karzai meeting with President Obama in Washington this week


• Felbab-Brown: Afghan politics are corrupt; army not ready for 2014 troop pullout


• She says Taliban, insurgents, splintered army, corrupt officials are all jockeying for power


• U.S. needs to commit to helping Afghan security, she says, and insist corruption be wiped out

Editor's note: Vanda Felbab-Brown is a senior fellow in foreign policy at the Brookings Institution. Her latest book is "Aspiration and Ambivalence: Strategies and Realities of Counterinsurgency and State-Building in Afghanistan."

(CNN) -- Afghan President Hamid Karzai is meeting this week with President Obama in Washington amid increasing ambivalence in the United States about what to do about the war in Afghanistan.

Americans are tired of the war. Too much blood and treasure has been spent. The White House is grappling with troop numbers for 2013 and with the nature and scope of any U.S. mission after 2014. With the persisting corruption and poor governance of the Afghan government and Karzai's fear that the United States is preparing to abandon him, the relationship between Kabul and Washington has steadily deteriorated.

As the United States radically reduces its mission in Afghanistan, it will leave behind a stalled and perilous security situation and a likely severe economic downturn. Many Afghans expect a collapse into civil war, and few see their political system as legitimate.

Karzai and Obama face thorny issues such as the stalled negotiations with the Taliban. Recently, Kabul has persuaded Pakistan to release some Taliban prisoners to jump-start the negotiations, relegating the United States to the back seat. Much to the displeasure of the International Security Assistance Force, the Afghan government also plans to release several hundred Taliban-linked prisoners, although any real momentum in the negotiations is yet to take place.

Vanda Felbab-Brown

Washington needs to be careful that negotiations are structured in a way that enhances Afghanistan's stability and is not merely a fig leaf for U.S. and NATO troop departure. Countering terrorism will be an important U.S. interest after 2014. The Taliban may have soured on al Qaeda, but fully breaking with the terror group is not in the Taliban's best interest. If negotiations give the insurgents de facto control of parts of the country, the Taliban will at best play it both ways: with the jihadists and with the United States.

Negotiations of a status-of-forces agreement after 2014 will also be on the table between Karzai and Obama. Immunity of U.S. soldiers from Afghan prosecution and control over detainees previously have been major sticking points, and any Afghan release of Taliban-linked prisoners will complicate that discussion.

Karzai has seemed determined to secure commitments from Washington to deliver military enablers until Afghan support forces have built up. The Afghan National Security Forces have improved but cannot function without international enablers -- in areas such as air support, medevac, intelligence and logistical assets and maintenance -- for several years to come. But Washington has signaled that it is contemplating very small troop levels after 2014, as low as 3,000. CNN reports that withdrawing all troops might even be considered.

Everyone is hedging their bets in light of the transition uncertainties and the real possibility of a major security meltdown after 2014. Afghan army commanders are leaking intelligence and weapons to insurgents; Afghan families are sending one son to join the army, one to the Taliban and one to the local warlord's militia.

Patronage networks pervade the Afghan forces, and a crucial question is whether they can avoid splintering along ethnic and patronage lines after 2014. If security forces do fall apart, the chances of Taliban control of large portions of the country and a civil war are much greater. Obama can use the summit to announce concrete measures -- such as providing enablers -- to demonstrate U.S. commitment to heading off a security meltdown. The United States and international security forces also need to strongly focus on countering the rifts within the Afghan army.

Assisting the Afghan army after 2014 is important. But even with better security, it is doubtful that Afghanistan can be stable without improvements in its government.

Afghanistan's political system is preoccupied with the 2014 elections. Corruption, serious crime, land theft and other usurpation of resources, nepotism, a lack of rule of law and exclusionary patronage networks afflict governance. Afghans crave accountability and justice and resent the current mafia-like rule. Whether the 2014 elections will usher in better leaders or trigger violent conflict is another huge question mark.

Emphasizing good governance, not sacrificing it to short-term military expediencies by embracing thuggish government officials, is as important as leaving Afghanistan in a measured and unrushed way -- one that doesn't jeopardize the fledgling institutional and security capacity that the country has managed to build up.

Karzai has been deaf and blind to the reality that reducing corruption, improving governance and allowing for a more pluralistic political system are essential for Afghanistan's stability. His visit provides an opportunity to deliver the message again -- and strongly.

Bill Richardson, Eric Schmidt arrive in North Korea

Richardson told The Associated Press in an exclusive interview in Pyongyang that the group is also asking for fair and humane treatment for an American citizen detained in North Korea.

"The citizens of the DPRK (North Korea) will be better off with more cell phones and an active Internet. Those are the three messages we've given to a variety of foreign policy officials, scientists" and government officials, Richardson said.

He is accompanied by Google Executive Chairman Eric Schmidt and Google Ideas think tank Director Jared Cohen on what Richardson has called a private, humanitarian trip. Schmidt, who is the highest-profile U.S. business executive to visit North Korea since leader Kim Jong Un took power a year ago, has not spoken publicly about the reasons behind the journey to North Korea.

The high-profile visit comes just weeks after North Korea launched a long-range rocket to send a satellite into space. Washington has condemned the launch as a banned test of missile technology.

Schmidt, who oversaw Google's expansion into a global Internet giant, speaks frequently about the importance of providing people around the world with Internet access and technology. Google now has offices in more than 40 countries, including all three of North Korea's neighbors: Russia, South Korea and China, another country criticized for systematic Internet censorship.

He and Cohen have collaborated on a book about the Internet's role in shaping society called "The New Digital Age" that comes out in April.

Using science and technology to build North Korea's beleaguered economy was the highlight of a New Year's Day speech by leader Kim Jong Un.

New red banners promoting slogans drawn from Kim's speech line Pyongyang's snowy streets, and North Koreans are still cramming to study the lengthy speech. It was the first time in 19 years for North Koreans to hear their leader give a New Year's Day speech. During the rule of late leader Kim Jong Il, state policy was distributed through North Korea's three main newspapers.

Holmes Played Childish Games After Aurora Carnage

As police confronted the movie theater carnage and a massive booby trap left behind by accused Aurora gunman James Holmes, the suspect loopily played with hand puppets, tried to stick a metal staple in an electrical socket and clamly flipped a styrofoam cup, according to court testimony today.

Holmes, 25, displayed the bizarre behavior once he was in custody and taken to Aurora police headquarters after the shooting that left 12 people dead and dozens injured, the lead investigator in the case testified today.

While being cross examined by Colorado public defender Daniel King, Police Detective Craig Appel was asked about the observations of two Aurora officers assigned to watch over Holmes in an interrogation room.

Appel said that to preserve possible gunshot residue, police had placed paper bags over Holmes' hands. One officer, King said, noted in a report that Holmes began moving his hands "in a talking puppet motion."

King asked if Appel was also aware that the officer "observed Holmes take a staple out of the table and tried to stick it in an electrical socket?" Appel confirmed Holmes' actions.

The officers also noted that they watched as Holmes began playing with an empty styrofoam cup, trying to "flip it" on the table.

While Holmes was carrying out his childish antics, police were puzzling over a complex booby trap Holmes had left behind in his apartment, according to testimony.

A gasoline-soaked carpet, loud music and a remote control car were part of Holmes' plan to trick someone into triggering a blast that would destroy his apartment and lure police to the explosion while he shot up a movie theater in Aurora, Colo., according to court testimony.

FBI agent Garrett Gumbinner told the court that he interviewed Holmes on July 20, hours after he killed 12 and wounded 58 during the midnight showing of "The Dark Knight Rises."

"He said he rigged the apartment to explode to get law enforcement to send resources to his apartment instead of the theater," Gumbinner said.

His plan failed to prompt someone into triggering the bombs.

Gumbinner said Holmes had created two traps that would have set off the blast.

The apartment was rigged with a tripwire at the front door connected to a mixture of chemicals that would create heat, sparks and flame. Holmes had soaked the carpet with a gasoline mixture that was designed to be ignited by the tripwire, Gumbinner said.

"It would have caused fire and sparks," the agent said, and "would have made the entire apartment explode or catch fire."

Holmes had set his computer to play 25 minutes of silence followed by loud music that he hoped would cause a disturbance loud enough that someone would call police, who would then respond and set off the explosion by entering the apartment.

Gumbinner said Holmes also told him he rigged a fuse between three glass jars that would explode. He filled the jars with a deadly homemade chemical mixture that would burn so hot it could not be extinguished with water.
