Titan and Mercury: Challenges to Billions of Years

first_img(Visited 47 times, 1 visits today)FacebookTwitterPinterestSave分享0 News from Titan and Mercury continue to challenge current theories that they formed billions of years ago.MercuryScience Magazine highlighted new results from the MESSENGER spacecraft, now orbiting the inner planet, about deep ice found in shadowed craters in its polar regions.  For ice to be stable, it would have to be at a very low temperature to avoid loss by sublimation, requiring it remain permanently blocked from the heat of the nearby sun, and blanketed with an insulating layer of dust.  Theoretically, such temperatures can be achieved in shadowed craters, but can such deep deposits of water ice and organics be expected to survive for billions of years?1.  Planetary scientists are never at a loss to rescue the old ages with various “scenarios” of how the ice stays there.  Neumann et al. published evidence for bright and dark deposits at the poles.  The dark areas may have a protective blanket over the ice, but light areas appear to be “deposits of nearly pure water ice up to several meters thick.”  To account for these, they had to invoke comets as delivery vehicles to replenish the ice over geologic time:Detailed thermal models suggest that surface temperatures in the majority of the high-latitude craters with RB [radar-bright] deposits that MLA [Mercury laser altimeter] has observed to date are too warm to support persistent water ice at the surface, but the temperatures in their shadowed areas are compatible with the presence of surficial dark organic material. Modeled subsurface temperatures in these dark regions are permissive of stable water ice beneath a ~10-cm-thick layer of thermally insulating material. In contrast, thermal modeling of the bright areas is supportive of surface water ice. This interpretation of the surface reflectance at 1064 nm is fully consistent with the radar results as well as with neutron spectroscopic measurements of Mercury’s polar regions. The bright and dark areas can be ascribed collectively to the deposition of water and organic volatiles derived from the impacts of comets or volatile-rich asteroids on Mercury’s surface and migrated to polar cold traps via thermally stimulated random walk.2.  In another paper in the same issue of Science, Lawrence et al. agree with the comet hypothesis.  There’s a lot of water up there:Combined neutron and radar data are best matched if the buried layer consists of nearly pure water ice. The upper layer contains less than 25 weight % water-equivalent hydrogen. The total mass of water at Mercury’s poles is inferred to be 2 × 1016 to 1018 grams and is consistent with delivery by comets or volatile-rich asteroids.Even so, depletion of the ice by sublimation is rapid enough that they said, “The average thickness of the upper layer inferred from neutron spectrometry therefore suggests that Mercury’s polar water ice was emplaced sometime in the last 18 to 70 My” [million years], a tiny fraction of the assumed 4.5 billion years Mercury has supposedly been orbiting the sun.3.  Paige et al. took on the task of modeling how long water ice could survive for billions of years.  Yes, sublimation can be very slow (1 mm per billion years) if the conditions are right.  A lot depends on the assumptions and the temperature:…the temperature at which a water ice deposit can be considered thermally stable depends on the time scale under consideration. At a temperature of 102 K, for instance, a meter-thick layer of pure water ice would sublimate to space in 1 billion years, whereas at a temperature of 210 K, a meter-thick layer of pure water ice would sublimate in 35 days.But under certain measured conditions, a one-meter depth of ice would sublimate in just 1000 years, they said:Today, thick deposits of ground ice are found near 75°N in areas with biannual maximum surface temperatures in excess of 150 K. At these temperatures, pure exposed water ice deposited by a cometary impact would sublimate at a rate of 1 m per 1000 years. The ice deposit would disappear on time scales of tens of thousands of years if not thermally protected by a ~10-cm-thick layer of overlying ice-free material, but this geometry is problematic because the time scales for burial to these depths by impact-gardened soil from adjacent regions is estimated to be on the order of tens of millions of years.In short, they decided that the dark deposits require replenishment.  “Because metastable ice deposits must accumulate on time scales that are shorter than those at which they sublimate, the formation of the MLA-dark deposits by sublimation lag is compatible with episodic deposition of water and other volatiles by asteroids and comets.”4. In a review of these three papers in the same issue, Paul G. Lucey described a “wet and volatile Mercury” that requires ongoing dynamical processing to last very long.  His description of what is required sounds like a stretch, a composite explanation of maybe this, maybe that:Mercury’s polar cold traps appear to have been filled by one or more comet impacts that introduced massive quantities of water and other volatile vapors in the tenuous atmosphere that promptly migrated to the polar cold traps. Ices began to immediately sublimate, and to acquire organic lag deposits, probably from radiation-induced chemical synthesis. The colder parts of the poles now exhibiting radar anomalies retained water ice below the lag deposit, while in warmer portions the ice entirely sublimed away, leaving the low-reflectance organic residue. Not depicted are the rare very-high-reflectance spots that are confined to the coldest portions of the pole. These may indicate a slow continuous production of water from small wet meteorites, solar wind proton interactions with oxygen in Mercury’s surface, or inhibition by the very low temperatures of the organic synthesis occurring elsewhere.He says “the new data reveal a dynamic history of these deposits,” meaning that theory requires a dynamic history, not that the data actually reveal it.  The water ice won’t last long.  It requires continual resupply:The results also show that the charging of the cold traps can temporarily overcome thermal instability and can be used to derive a high lower limit on the amount of water vapor that can be at least transiently retained in a transient atmosphere of Mercury in a comet impact to account for the distribution of the dark deposits.TitanFar out in the cold at Saturn, Titan presents other long age problems.  After 8 and 1/2 years in orbit, the Cassini spacecraft has radar-mapped about 50% of the surface.  A study of Titan’s 30 or so craters discovered so far, compared with those on the comparably sized moon Ganymede at Jupiter, shows Titan’s craters generally shallower, suggesting infilling of some sort.  Some suggest the sand from the ubiquitous dunes that belt the equatorial regions.  A NASA press release echoed on Science Daily describes the head-scratching required between finding sources of methane (rapidly depleted by the solar wind) and crater-filling mechanisms, as revealed by the number of “However” clauses:“Since the sand appears to be produced from the atmospheric methane, Titan must have had methane in its atmosphere for at least several hundred million years in order to fill craters to the levels we are seeing,” says Neish. However, researchers estimate Titan’s current supply of methane should be broken down by sunlight within tens of millions of years, so Titan either had a lot more methane in the past, or it is being replenished somehow.Team members say it’s possible that other processes could be filling the craters on Titan: erosion from the flow of liquid methane and ethane for example. However, this type of weathering tends to fill a crater quickly at first, then more slowly as the crater rim gets worn down and less steep. If liquid erosion were primarily responsible for the infill, then the team would expect to see a lot of partially filled craters on Titan. “However, this is not the case,” says Neish. “Instead we see craters at all stages; some just beginning to be filled in, some halfway, and some that are almost completely full. This suggests a process like windblown sand, which fills craters and other features at a steady rate.”For those who want to relive the exciting landing of the Huygens Probe on Titan 8 years ago this month, Astrobiology Magazine posted the European Space Agency’s latest animation re-creating its bouncy, skidding landing from various angles.  Viewers will notice the cloud of dry dust cast up into the atmosphere, re-emphasizing the contrast between the predicted global ocean and the reality of a mostly dry world.One measure of the strength of a scientific hypothesis is the number of auxiliary hypotheses required.  A recent creation of these worlds requires very few additional assumptions.  But when secular astronomers have to bring in boatloads of comets and “wet asteroids” to keep Mercury’s poles icy, or an unknown mechanism for keeping Titan’s methane “replenished somehow” (see the hands wave), the burden is on them.last_img read more

Will Google Chrome OS Bring Us the Mythical GDrive?

first_imgTop Reasons to Go With Managed WordPress Hosting Related Posts A Web Developer’s New Best Friend is the AI Wai… Perhaps it has something to do with the fact that Picasa, unlike Docs, is a combination of desktop software and a web service. The service’s Web Albums feature is more like flickr, a place where photos are shared either publicly or privately with friends and family. However, it’s the desktop software that provides the organizational and editing tools needed to manage your photo library. Integrating Picasa into Google Docs now would only be a partially complete user experience – you still need the desktop software component to access all the functionality the service provides. Maybe Google is waiting to provide that complete experience via Chrome OS? It’s not that far-fetched. Picasa is already available in a Linux version (and Chrome OS will sit on a Linux kernel). But perhaps what really has us hopeful was one extra word in the Google Chrome OS announcement: “…most of the user experience takes place on the web.”Most? Maybe Chrome OS will let you manage your photos via desktop software that integrates with a web service and is accessible via your Google Docs interface? Will that interface then be “GDrive?” GDrive Needs Music…Or Does It? If you can’t save your tunes online to your cloud storage drive, then you don’t really have any cloud storage drive worth using, do you? Even if Google Docs added in Picasa, we’d still be looking at an incomplete GDrive solution if we didn’t have access to our music. For GDrive to become the true “hard drive in the sky” it needs to accommodate other sorts of files besides just documents and photos. It would make sense if Google leveraged their existing partnership with Amazon, who provides the music store on the T-Mobile G1 and the myTouch 3G, phones running Google’s mobile phone OS called Android. With Amazon’s online interface, you can already browse, listen to samples, and buy MP3s via the web. The question is, will Chrome OS integrate some sort of music store for letting you buy music (maybe via Amazon) from your computer? And if so, will you be able to download and save those files to the hard drive of the computer itself? Or will Google come up with some revolutionary new “music in the cloud” service that lets you accumulate an online library of songs available at any time for streaming from your computer? Or then again, does Chrome OS even need an iTunes alternative in order to compete? Maybe they will simply offer a web app like Pandora. There have been no hints as to what direction Google will go with this or if they will ignore users’ need for music altogether in the new OS.But like this author’s sister recently said after being told about Chrome OS: “why would I want a computer that couldn’t run iTunes?”We hope Google will keep that in mind.GDrive and Video? Would a true GDrive solution offer a way for users to store video files, too? It almost seems redundant to have an online storage system for video since Google also owns the giant video sharing portal that is YouTube. Still, you couldn’t really have a cloud storage system that restricted you to storing only documents and photos and call it “GDrive.” But integrating the supposed GDrive with YouTube – especially via Chrome OS – could be tough. Today, videos still need to be on your computer’s hard drive for editing purposes. And, of course, uploading a file from your computer is how you get them online to sites like YouTube. Althouugh GDrive could easily include a way for you to view your online files at YouTube, getting them there via Chrome OS would be more difficult. However, if Chrome OS allowed you to save files on its hard drive, then the YouTube uploader built into Chrome could simply know to look in that particular video storage location when you go to publish them online. Making this a seamless experience for the end user would be the challenge. Again, there are no hints as to Google’s plans in this department, but it would seem odd if Chrome OS didn’t attempt to integrate one of Google’s top properties deep into its system. What Else?Although this article is just pure speculation, we think that if we ever see GDrive revealed, there’s a chance that it would occur when it’s introduced as a part of Chrome OS. What do you think? Why Tech Companies Need Simpler Terms of Servic… sarah perez Tags:#Google#web Last week, Google announced some interface changes to their Google Docs service that are designed to make finding your files easier. The changes are relatively minor – the “shared with” list has gone away, there’s a new “Sharing” menu, and you now have the ability to save your searches – but that hasn’t stopped some bloggers from theorizing that the shiny new UI is bringing us one step closer to the often theorized, yet never realized, “Google Drive” service, aka “your hard drive in the cloud.”Although we know this service exists in some form as an internal tool, Google has yet to release a version for public use. But with the latest announcements about the new Chrome operating system, we wonder: will Google Drive finally become a reality thanks to Chrome OS?Hints of GDriveIn January of this year, blogger Brian Ussery discovered an interesting tidbit of information tucked into a file used by Google Pack, the bundle of tools that Google thinks computer users need to set up a new machine. The file contained a reference to a product called GDrive, described as an “online file backup and storage” system:“GDrive provides reliable storage for all of your files, including photos, music and documents. GDrive allows you to access your files from anywhere, anytime, and from any device – be it from your desktop, web browser or cellular phone.”Of course, the blogosphere immediately went crazy over this information, sure that this time Google Drive was about to become a reality. And yet, like all the times before, nothing happened. GDrive didn’t launch, Google didn’t release any announcement, and disappointed bloggers everywhere moved on…again. Still, the hope for a true GDrive system just won’t die. It very well may be one of the blogosphere’s longest-running rumors. And now, with the recent announcement of Google’s new Chrome Operating System, an OS where “web-based applications will automatically work,” we wonder: will the mythical GDrive be included with the OS?GDrive Needs Picasa IntegrationFrom what we already know, Google has somewhat integrated Picasa into the backend of Google Docs, but, for whatever reason, they have not yet switched this on. To see what we mean, visit this link: http://docs.google.com/#photos. You’ll be taken to Google Docs where a message will appear “No Photos.” In other words, Picasa image search works in Google Docs, but there’s nothing for it to search until the two services are fully integrated. But this functionality was discovered nearly a year ago. What’s the holdup? 8 Best WordPress Hosting Solutions on the Marketlast_img read more

OSU won, 3-1.Credit: Mark Batke / Lantern photographerA change in mindset might alter the fortunes of the Ohio State women’s volleyball team this weekend.After dropping eight straight Big Ten matches, junior defensive specialist Alyssa Winner said the Buckeyes have a new focus point going into their next match.“This new thing we want to do is (win) five points at a time, so five sets of five in each game,” she said.Freshman middle blocker Taylor Sandbothe said the new outlook can help keep the team from looking too far ahead.“Kind of keeping the game in sight, not thinking about 25 (the number of points needed to win a set) automatically,” she said. “Thinking about first to five, first to 10 (instead).”OSU is scheduled to embrace this new philosophy as the team returns to St. John Arena this weekend to host Indiana at 7 p.m. Friday before welcoming No. 14 Purdue at the same time Saturday.The Hoosiers are one of only two Big Ten teams OSU has bested this season, along with Michigan, and also represent the Buckeyes’ most recent Big Ten victory.Since beating Indiana in five sets Oct. 5 in Bloomington, Ind., OSU has not won a match. Most recently, the Buckeyes lost to then-No. 14 Michigan State Nov. 1, before dropping a 3-2 decision at No. 17 Michigan Nov. 2.Senior outside hitter Kaitlyn Leary, who tallied a career-high 31 kills against the Wolverines, said there are still positives to take from the loss.“There’s a lot we can take from that game, I think we played really well,” she said. “We battled the whole game.”Leary said the team is getting close to a breakthrough.“Our team played well, so we’re getting closer to that win that we need,” she said. “(We’ll) just work really hard this week to get that ‘W’ this weekend.”Junior setter Taylor Sherwin agreed there can be positives taken from the losses in Michigan, but added there is room for growth going forward.“We just keep growing as a team and keep staying together and fighting on the court with each other,” she said.Winner said she is excited to be back on the Buckeyes’ home court, especially coming off another road trip.“It’ll feel really good, since we were away last weekend and we need to get a win,” she said. “Having our fans behind us will be great. It’ll be nice to be back here and not have to travel.”While the team will have the home support for its matches against Indiana and Purdue, the homestand will be short-lived. The Buckeyes are scheduled to hit the road again next weekend for matches against No. 9 Minnesota in Minneapolis, Minn., Nov. 15 and No. 16 Wisconsin in Madison, Wis., Nov. 17. read more

Track and Field Past Ohio State Rachel Weber still running toward dream

Rachel Weber running at Tracktown USA last June during the NCAA championship. Credit: Courtesy of Rachel Weber.She keeps her head up, chin down, eyes level while gliding through each stride with even distance as her hair whisks side to side. Rachel Weber, a fifth-year at Ohio State in strategic communications, is a runner’s runner.“I just fell in love with it and I fell in love and competing and the adrenaline that you get,” Weber said.Weber finished 13th at the NCAA Outdoor Championships at Tracktown USA last June in Eugene, Oregon. It was the last time she would run for the Buckeyes, but she doesn’t plan for it to be her last visit to that track.Although she has ran out of eligibility at Ohio State, this was not her last meet competing against other collegiate programs.Ohio State has continued to have ties to Weber’s post-collegiate running career almost a year after she took off her scarlet and gray jersey.Professional track and field isn’t as straightforward as well-known leagues like the NBA or NFL. Runners sometimes compete for track clubs, which are often smaller in scale, or they receive sponsorships from brands like Nike, Asics and Adidas that allow them to support their career.There also is separation between professional and post-collegiate. Weber runs for Columbus Running Company and it supports her. However she is not getting a salary to run for it, although it pays her for as an employee who works at its store.“I am really, really fortunate that Columbus Running Company supports me and they help support gear, travel and teammates and it’s awesome,” Weber said. “When I graduate hopefully I will be looking to be up more on that professional level with a professional contract.”She has a new coach, Rob Meyers, an Ohio State alumnus who has the fourth-fastest 1,500-meter time (3:41) in school history and the fifth-fastest mile time (4:03) in school history.Meyers met Weber through the running camps that he and his family host in the summer. Weber was a volunteer who brought an infectious smile to running, Meyers said.“I knew that she was really energetic and positive. She was passionate for the sport,” Meyers said. “As for as the running camp side of things go, we obviously invited her back.”Their relationship changed last summer when Weber reached out to Meyers to become her personal coach.“First I was a little caught off guard, but the more I thought about it, she needed to stay in Columbus to finish her education” Meyers said. “It seemed like something that I was able to work out and I was excited about.”Beyond working with Weber, Meyers coaches cross country and track and field at Fairfield Union High School. Weber has assisted him, working as a volunteer coach and training there for outdoor season. Competing for Columbus Running Company has sometimes led Weber to race against her old teammates. In the indoor season, Weber ran at the Meyo Invitational in South Bend, Indiana.“Meyo is one of the nearest and dearest meets to my heart. For I have had several really, really poor races there.” Weber said, “Like some of the worst races in my entire college career.”This past Meyo Invitational had some slight differences. Mainly, she was competing against Ohio State in the 800-meter run, the event in which she set the school record several months before — though none of Ohio State’s runners competed in the same heat.Weber’s goals for the meet also slightly changed. This year it was to make the U.S. Track and Field standard at 2:03 and the International Association of Athletics Federations standard at 2:02. Weber won her heat, but she ran a 2:07.Even while no longer with the Buckeyes, there was nothing new to the meet for Weber.“Even in college like we would show up with the team but then it was like I had my own up and a lot of times I was the only one running a certain event,” Weber said. “I had to get really good at being independent and having my own warmup routine and own warmup schedule.”During the winter, Weber also trained at the French Field House alongside the current Buckeyes and intermingled with them between exercises. She even saw a personal trainer from Ohio State before her practice. Sara Vergote, Ohio State’s distance and cross country coach, took some time and helped Weber out during one of her most intense practices of the year, in which the goal was for Weber to push herself as far as she could possibly go. Vergote said she stopped Weber when she started to lose her running form and risk injury. All along this road, Weber was driven by her love for running. Speed just followed her afterward.She started running 5ks with her mom, Christine Weber-Wheeler, when she was just five years old. Growing up Weber wanted always wanted to be an athlete — just in soccer. “I played club soccer and so I always envisioned myself like oh, ‘I’m going to be the next Mia Hamm,’” Weber said.But her passion switched to track, specifically the 400-meter dash. At Dublin Coffman, she moved up to the 800-meter run and finished third at the high school state championship meet, then came to Ohio State. During her time at Ohio State she broke the school record for the 800-meter run record (2:02) and posted the second-fastest 1,500-meter run. Weber’s passion for running spreads out much further though than the events she ran or the times she has clocked.“Like I still would choose to run again and again and again because of the friendships that it’s given me and the fulfillment that it gives you,” Weber said.She has gone to the Columbus Marathon, not to run, but to cheer on the runners. In addition to her work at Fairfield Union, she also volunteers at Dublin Coffman.“She is an amazing influence to have for these athletes.” Meyers said.For Weber, the Olympics has been the dream, but she knows the odds can be tough to predict. Olympic qualifying at Tracktown USA — back in Eugene — happens one day every three years.“I think it’s a wonderful gift to have to be able to compete and experience the joy and the freedom that running bring me.” Weber said, “So my goal is to enjoy the entire process leading up to the Olympics.” read more

First Team Match

first_imgSaints fell behind after two early tries from Joe Westerman and Carlos Tuimavave, but responded and ran away with the game scoring 11 tries thanks to four tries from Kevin Naiqama, a hat-trick from the returning Adam Swift, plus two from the excellent Jonny Lomax on his 200th career appearance as well as scores from young Jack Welsby and Lachlan Coote.Justin Holbrook made four changes following the win over Wigan, as Adam Swift came with Tommy Makinson in at centre with Mark Percival out injured. Matty Lees and Joseph Paulo both started and there was a Saints debut for Joe Batchelor with Jack Welsby on the bench.A fast start from the visitors saw them race into a 10-0 lead inside the opening 12 minutes after Westerman latched onto a kick through from Jake Connor for the opening try. Minutes later following a 40/20 from Marc Sneyd the ball was thrown out wide and Tuimavave touched down in the corner to give Hull a 10-0 point lead.Saints hit back minutes later after back to back penalties put us in prime position and Lomax was over after receiving the pass from Joseph Paulo. Coote added the extras.On the very next set Saints were in again and this time it was all about Lomax. The England international threw the dummy and then stepped back inside three Hull defenders to walk under the posts. Coote adding the two giving Saints a 12-10 lead after just 20 minutes.Saints were now in full control and two tries followed in three minutes. Naiqama with the first of his four after Lomax put him away down the line and the centre backed himself to score in the corner.Then Swift, making his first start of the season, was over in the corner after excellent handling from Paulo and Lomax allowed Coote to find the flying winger.The scoring in the first half didn’t stop there. In the final minute of the first half Paulo put Coote through a gap and the elusive full back stepped past Connor to score under the sticks as Saints headed into the break 30 points to 10 ahead.The second half started like the first with Hull on top. Inside the opening minutes of the second half they pulled a try back. After keeping the ball alive, Jez Litten was first to the loose ball to pick up and score. Sneyd adding the extras.It didn’t take Saints long to hit back though as Naiqama fed the ball out wide to Swift and the winger finished spectacularly in the corner.Swift was in again for his hat-trick on the hour mark after a diving finish in the corner, Naiqama again putting the winger away. Coote converting off the touch line bringing the score to Saints 40-16 Hull FC.Saints were now in full flight and after excellent footwork from Lomax he found the gap and on his way down somehow found an offload to Naiqama to go under the posts for his second of the game.Welsby was next to go over as the ball went from left to right and back again before the youngster claimed the long pass to score and bring up the 50 points.In the final five minutes Naiqama grabbed his hat-trick, flying over in the corner before he bundled his way over again for his fourth and Saints eleventh try of the game to bring up the impressive 60 point victory for Saints.Match SummaryTries: Jonny Lomax (18, 21), Kevin Naiqama (29, 64, 75, 78), Adam Swift (32, 53, 59), Lachlan Coote (39), Jack Welsby (70).Goals: Coote 8 from 10 and Richardson 1 from 2.Starting 13: Lachlan Coote, Adam Swift, Kevin Naiqama, Tommy Makinson, Regan Grace, Jonny Lomax, Danny Richardson, Matty Lees, James Roby, Luke Thompson, Joe Batchelor, Morgan Knowles, Joseph Paulo.Interchanges: Kyle Amor, Dom Peyroux, Jack Ashworth, Jack Welsby.Hull FC:Tries: Joe Westerman (7), Carlos Tuimavave (11), Jez Litten (48).Goals: Marc Sneyd 2 from 3.Starting 13: Jake Connor, Bureta Faraimo, Cameron Scott, Carlos Tuimavave, Ratu Naulago, Albert Kelly, Marc Sneyd, Scott Taylor, Dean Handley, Masi Matongo, Mark Minichiello, Sika Manu, Joe Westerman.Interchanges: Jordan Thompson, Christopher Green, Jez Litten, Bradley Fash.HT: 30-10 FT: 62-16REF: R.HicksATT: 11,268last_img read more

Rice U physicist available to discuss Large Hadron Collider results

Im Stuck in the Facebook Trap

But it doesn’t need to be subject to regulation: it needs a conscience. Image credit: via PC Mag Learn how to successfully navigate family business dynamics and build businesses that excel. Lead Mobile Analystcenter_img March 21, 2018 Facebook is the ultimate toxic friend. You’ve probably had a friend like this in your life: a charming, charismatic, entirely non-self-aware pal who blithely leaves destruction in their wake but will always be forgiven, because they’re fun to be around and to ditch them would be social suicide.The Facebook algorithm, the artifically intelligent editor of our Facebook lives, is designed to activate passionate responses from its users. It’s not evil, if you think evil requires intent to harm, but it verges on evil in that it makes decisions without caring about who it hurts. The company doesn’t care whether it’s getting good passion or bad passion, as long as it gets that sweet, sweet attention.Personally, I can’t quit Facebook because what it does right, it does very right: connecting families and old friends. I’ve found old high school friends, peered into the personal side of coworkers’ lives, and kept up on neighborhood activities. If you ditch Facebook, and your friends and family still use it, you end up uninformed and disconnected.Facebook’s power is its network effect. When everyone you know uses Facebook, they probably aren’t going to move somewhere else. Defaults and inertia are powerful.Because it turns out that bad passion is more engaging than good passion, Facebook is destroying us through a diet of noise and anger. It’s in the news right now because a consulting firm, Cambridge Analytica, impermissibly gamed Facebook’s system to target various political ads. But Cambridge did what Facebook does all the time, in terms of optimizing ads for attention. Facebook is just annoyed that it wasn’t the one in control.I’m far less concerned about the ins and outs of whether Cambridge did a bad thing, or whether individual Russian trolls targeted a specific ad at a specific key voter, than I am about Facebook’s overall status as a platform that feeds on anger. Lies are more entertaining than truth; hate gathers more attention than contentment. A happy baby is great, but a cry of rage trumps it. Facebook begs for the worst, the click-baitiest, the dopamine fiendiest. It encourages it. It amplifies it. And it makes it look like it’s coming from your friends, and that they want to en{g,r}age about it. That’s the poison, not any specific political advertisement.The engagement factor is what makes Facebook different from Xaxis, Google, Acxiom or other targeted advertising platforms that could also be serving you fake news. Google’s ads don’t look like they’re from people you trust, and they don’t invite a conversation. They don’t pull you into an attention vortex that we are biologically programmed never to escape.Facebook must die; long live Facebook.I can’t find any real alternative to Facebook to stay in touch with far-flung groups of friends, ad-hoc alumni associations, networks of ancillary cousins, or constantly reconfiguring neighborhood parent activity clusters. Like many people, I’m stuck in the Facebook trap.I’d love to say that Facebook will fade; we’re already seeing the backlash among kids. My daughter says it’s evil, and she and her friends don’t want to use it. That’s great! They should learn from our mistakes and burn those mistakes down.Unfortunately, a social network that’s eventually all old people being fed highly optimized fake-news memes by trolls and instigators will still go pretty far towards destroying America. Old people vote and at a higher rate than younger folks.Only Facebook can fix Facebook, and Facebook doesn’t want to. Regulation won’t fix it, because Facebook’s problem isn’t really that it’s collecting or sharing biographical data. It’s that the map of our interactions on Facebook itself tell it how to enrage us, and the algorithm knows that enraging us, dividing us, and telling us colorful lies will keep us engaged.Facebook staff need to not merely label the lies, but cut them off; to not merely wring hands about trolls, but ban them; to understand that its system is an editor making choices all the time about what users see, and to start making choices based on the world they want to live in. Facebook doesn’t need to be subject to regulation: it needs a conscience. Until then, it will continue to do damage. 4 min read Add to Queue –shares Facebook Sascha Seganlast_img read more
