Oort cloud tosses astronomers a cometary curveball | Science News - 0 views

  • a mountain-sized chunk of primordial solar system, will approach within 2 million kilometers of the sun and either fall apart or slingshot back into deep space. Astronomers aren’t sure yet how much of a spectacle ISON will be for earthbound observers, but from their vantage point the comet is already providing a brief, unprecedented glimpse into what the solar system was like in its infancy.
  • “It’s the sort of thing I’ve been waiting for my whole career,”
  • hat probably indicates large amounts of ice near the comet’s surface, where the sun can easily drive it off, he says. The finding confirmed that ISON is on its first pass through the inner solar system, not a periodic visitor like Halley’s comet.

  • Looking ahead, astronomers found that ISON will pass within a cosmic whisker of the sun, close enough to potentially be ripped apart by the star’s intense gravity.
  • Unlike previous sungrazing comets, ISON was detected more than a year out, giving researchers at the world's major ground-based telescopes plenty of time to watch its approach to the sun.
  • . Because sunlight interacts with gas and dust to make comets light up, Meech thinks the best explanation for her team’s data is that ISON’s nucleus contained a buried layer of solid carbon monoxide, a featherweight molecule that rapidly turns to gas when exposed to sunlight.
  • Because scientists have no data on the comet’s rotation, Knight and Walsh conclude that ISON will probably survive. However, Knight acknowledges that other comets have broken up for no known reason, and he is prepared for surprises.
  • Earthbound stargazers won’t notice these details, but motivated observers may be able to spot a new object in the predawn sky

Fact Check: This Pizzeria Is Not a Child-Trafficking Site - The New York Times - 0 views

  • images, pilfered from the restaurant’s social media pages and the personal accounts of friends who had “liked” Comet Ping Pong online. Those photos have been used across dozens of websites. Parents, who declined to talk publicly for fear of retribution, have hired lawyers to get the photos removed.
  • Musicians who have performed at Comet Ping Pong have been pulled in, too. Amanda Kleinman, whose band, Heavy Breathing, has performed there several times, deleted her Twitter account after the abusive comments became overwhelming. Similar comments have flooded her YouTube music clips
  • “We are at a dangerous place in American culture where a good percentage of people aren’t distinguishing what is a real news source based on real reporting and fact-checking and only reinforcing pre-existing ideas they have,” Ms. Kleinman said.

  • The frustration has been compounded by the lack of recourse for Mr. Alefantis, his friends and employees. Yelp blocked the comments sections of Comet Ping Pong’s review page after reports of abusive comments and fake news in reviews. YouTube said it prohibits threats, harassment and hate speech and has tools for flagging violations and filing complaints for the site to take further action, but has largely not blocked comments on these videos. Twitter declined to comment, and Facebook did not have any further comment.
  • After employees and Mr. Alefantis complained to Reddit about how Comet Ping Pong was being targeted on the site, the #pizzagate discussion thread posted a warning that revealing personal information about individuals was prohibited.“We know that we have more work to do and we take our responsibility to address online abuse seriously,” Reddit said in a statement

Trump Fires Adviser's Son From Transition for Spreading Fake News - The New York Times - 0 views

  • At the Defense Intelligence Agency, his staff members even coined their own name for his sometimes dubious assertions: “Flynn facts.”
  • “He has regularly engaged in the reckless public promotion of conspiracy theories that have no basis in fact, with disregard for the risks that giving credence to those theories could pose to the public,” Representative Adam Smith of Washington, the ranking Democrat on the House Armed Services Committee, said on Tuesday.
  • “Someone who is so oblivious to the facts, or intentionally ignorant of them, should not be entrusted with policy decisions that affect the safety of the American people,” Mr. Smith added.

  • His son, in contrast, showed no such restraint in the weeks before he was fired, regularly posting on Twitter about conspiracy theories involving Mrs. Clinton and her campaign staff well after the election.He continued to push his support for the fake news about Comet Ping Pong after his messages on Twitter about Sunday’s episode began attracting widespread attention. It was not until shortly before 3:30 p.m. Monday that he went silent on Twitter.
  • In one of the last messages he posted, he shared a post from another Twitter user who sought to spread a conspiracy theory that sprang up on the right-wing fringes after the shooting: that the suspect arrested at Comet Ping Pong, Edgar M. Welch, 28, of Salisbury, N.C., was actually an actor, and that the episode was a hoax cooked up to discredit the claim of a sex trafficking ring at the restaurant.

With Limited Budgets, Pursuing Science Smartly - NYTimes.com - 0 views

  • With the first presidential debate coming up on Wednesday, it is striking — if not surprising — how bland and predictable the candidates have been in discussing America’s role in space.
  • neither candidate, and neither party, has addressed the scientific question of why we want to bother with exploring space.
  • Maybe scientists should simply face reality and accept that science doesn’t play a central role in the government’s equation.

  • unmanned space exploration seems to me much more exciting and scientifically worthwhile than human spaceflight, especially at a time of restricted budgets and nascent technology.
  • human geologist could do in a few days what Curiosity may do in a year or two. But we aren’t likely to send geologists there anytime soon — and if we did, they wouldn’t be able to stay much longer than a few days, while Curiosity can silently and gently move about the planet for a decade or more, powered by its plutonium generator. Moreover, by the time we might get around to sending humans, in two to three decades at best, robots will have advanced to the point where they might easily compete in real time.
  • Over the coming decades we may send more robotic explorers to even harsher climes, maybe to explore deep oceans on Jupiter’s moon Europa, or to search on comets for telltale signs of life’s origins.

The Water in Your Glass Might Be Older Than the Sun - The New York Times - 0 views

  • Earth is old. The sun is old. But do you know what may be even older than both? Water.
  • more than 4.6 billion years ago.
  • That means the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself.
  • ...3 more annotations...
  • researchers analyzed water molecules in oceans for indicators of their ancient past.
  • “heavy water.” Water, as you know, is made up of two hydrogen atoms and one oxygen atom. But some water molecules contain hydrogen’s chunky twin, deuterium. (It contains a neutron in its nucleus, whereas regular hydrogen does not.)
  • They concluded that remnants of that ancient ice remain scattered across the solar system: on the moon, in comets, at Mercury’s poles, in the remains of Mars’ melts, on Jupiter’s moon Europa — and even in your water bottle.

Can Physicists Find Time Travelers on Facebook? - Robinson Meyer - The Atlantic - 0 views

  • the two scoured Twitter, Facebook, Google+ and a few other websites to find “prescient information”—that is, tweets and statuses about current events posted before the events became current. The only way someone could write such a post, they reasoned, is if they were visiting… from the future.

  • But that doesn’t quite mean anything. The authors admit that the study might have failed for many reasons: Time travelers might not have the ability to physically adjust the past; they might not have posted about the events the authors were looking for; they might have posted about the events but not turned up in a search. Time travelers might have also read the study or this news story about it, and been sure to making avoid any careless mistakes.
  • [G]iven the current prevalence of the Internet, its numerous portals around the globe, and its numerous uses in communication, this search might be considered the most sensitive and comprehensive search yet for time travel from the future.

Why We Can't Ignore Conspiracy Theories Anymore, Experts Say | Time - 0 views

  • Conspiracy theories, both powerful and enduring, can wreak havoc on society. In recent years, fringe ideas prompted a gunman to storm a Washington, D.C. pizzeria and may have motivated another to fatally shoot 11 worshippers inside a Pittsburgh synagogue. They are also largely to blame for a worldwide surge in measles cases that has sickened more people in the U.S. in the first half of 2019 than in any full year since 1994.
  • “very likely” inspire domestic terrorists to commit criminal and sometimes violent acts and “very likely will emerge, spread and evolve” on internet platforms, according to an intelligence bulletin obtained by Yahoo News.
  • “It’s increasingly becoming clear that lots and lots of people believe in them, and they have negative outcomes,” says Viren Swami, a social psychology professor at Anglia Ruskin University in the U.K., who has published several studies on conspiracy theories.

  • More recently, following Jeffrey Epstein’s apparent suicide in federal jail, Trump retweeted an uncorroborated theory that suggested the death of the well-connected financier, who was charged with sex trafficking of minors and conspiracy, was suspicious and somehow linked to former President Bill Clinton.
  • “The chief conspiratorialist of the last 10 years is now the President of the United States,” says Harvard University researcher Joseph Vitriol, who studies political psychology. “Because of that, what we might be seeing is increased influence and pervasiveness of these beliefs.”
  • “It used to be a lot harder for things to go viral,” says Micah Schaffer, a technology policy consultant who crafted YouTube’s first policies when he worked for the company between 2006 and 2009. “Now, without any human intervention, you could have a machine that says a lot of people are watching this and put it on blast to a mass audience.”
  • Facebook faced its own pressures to act in March after an Ohio teenager, who got vaccinated against his mother’s wishes, testified about the dangers of misinformation during a widely viewed Senate hearing
  • “Conspiracy theories are effective at doing the things that they do,” says Mike Wood, a lecturer at England’s University of Winchester, who specializes in the psychology of conspiracy theories. “They motivate people to take actions—to vote or to not vote, to vaccinate their kids or not to vaccinate their kids, to do all of these things that are important.”

Fortnite has reached The End - changing video game storytelling for good | Games | The ... - 0 views

  • There is no conventional “narrative” to Fortnite Battle Royale – Epic doesn’t provide an origin story for its endless 100-player wars, it doesn’t give us long cinematic scenes with characters explaining the world, the factions and the plot. Instead, Fortnite is split into a series of three-month-long seasons, each with a climactic event that suggests some kind of interdimensional struggle taking place over the future of the game’s isolated island locale.
  • Ostensibly, there’s no need for a narrative – Epic could, in theory, retain player interest simply by making sure there is a steady supply of new dance moves, costumes and scenic features to enjoy. Instead, the studio has built a vast functional universe in which an alien known as The Visitor is attempting to mend the space-time fissure around the island, and communicated this through systems of signs, signals and miracles – sort of like the Medieval Christian church
  • Indeed, it’s interesting how Fortnite has co-opted a lot of religious symbolism into the game’s suggestive narrative, from comets trailing across the sky, to the decidedly apocalyptic imagery of fire, brimstone and global destruction.

  • We have seen the rise of massively multiplayer adventures such as World of Warcraft, where global arching narratives are woven into the largely player-directed quests, and we have seen plenty of interesting live story experiments, such as the mostly single-player adventure Dark Souls allowing players to leave messages to each other within the game.
  • Fortnite has been criticised as a shallow, cynical machine of compulsion, its trendy dances and outlandish outfits a means of ensnaring younger players. But as a purveyor of new forms of storytelling, in which the community is left to construct its own narrative based around subtle semiotic systems and climactic events, it is a fascinating innovator.
  • For Season 10, Epic was always building toward something vast and catastrophic and upped the narrative signalling accordingly. Throughout the last months players have been able to find audiotapes hidden around the map in which The Visitor has made recordings about his attempts to fix a loop in time and prevent a singularity. It sounds like the ravings of a conspiracy theorist, echoing back the most extreme theories from the fanbase itself
  • But Fortnite is playing with storytelling concepts, tropes and systems while also providing a piece of blockbuster entertainment for millions of mostly teenage players. It’s like a new Marvel superhero movie being performed entirely in interpretive dance.
  • When Chapter 2 inevitably begins, bringing a new landscape with new gameplay features, it will be interesting to see where Epic goes next on its somewhat transgressive storytelling odyssey. It is, after all, quite hard to top the end of the world as a narrative device.
