Cosmologist Has a Sobering Thought: We Are Forever in the Dark About Dark Energy

first_imgAn evangelist for the standard model of cosmology is having a moment of penitence.  He is admitting to himself, and to the world, that “we will remain resolutely in the dark about dark energy.”    In a piece in New Scientist, Pedro Ferreira [Oxford] has revealed the vicious circle of assumptions that undermine confidence in the claims of modern cosmologists.  Most models assume a flat universe for convenience.  Without knowing the geometry of space-time, or the evolution of dark energy, or whether the cosmological constant (lambda) represents acceleration, we have no basis for assuming a flat universe.This means that we cannot pin down the geometry of space-time.  We are then caught in a vicious circle: to know the geometry of the universe we need to pin down dark energy.  Yet to determine how much dark energy there is, we need to know the geometry.  Knowing one without the other is futile and a recipe for disaster.    These recent results are sobering.  Having proselytised about the great discovery of the millennium, that the universe is flat, I now find myself backtracking.  And there is a sense of foreboding that it may never be possible to know our cosmos as well as we’d like to.Ferreira unraveled the hype behind COBE, WMAP and the other instruments and studies that seemed to support the standard model.  He was “brutally honest” about how little we actually know.  He talked about new findings that “shook my faith in the notion” that the universe is flat.  He ended his confession on a mildly optimistic note.  “Happily all is not lost: new experiments are being designed to probe the deepest recesses of the cosmos,” he said.  New probes and small projects are “chipping away at our ignorance.”  Getting a handle on the geometry of space-time “is just going to take a bit longer than we originally thought.”Cosmologists are the biggest hype marketers in the universe.  How many books have been written promoting a golden age of “precision cosmology”?  How many speeches have been given?  How many dazzling planetarium shows?  Ferreira is not the only evangelist that preached to us, “repent and believe the big bang gospel” (e.g., 11/02/2002).    Some skilled visualization can turn vicious circles into works of art.  In the land of logic, though, they are still vicious.  They have the habit of blinding the unwary of their own assumptions.  Christians should not trust the loud voices of salesmen on the big bang bandwagon promoting their snake oil potions of dark stuff.  Now that one of them has come clean, admitting its efficacy is doubtful, and that it might even be a “recipe for disaster,” have we learned our lesson?  Now that he has admitted that “it may never be possible to know our cosmos as well as we’d like to” would you drink his new, improved elixir next time?(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

UrbanSpoon Challenges OpenTable With iPad-Based Restaurant Reservations Service

first_imgWhat it Takes to Build a Highly Secure FinTech … Restaurant review site UrbanSpoon is slowly moving into OpenTable’s territory. About half a year ago, the company launched a very limited test of a basic reservations tracking system for restaurants in the Seattle area. At that time, however, restaurant owners could only use UrbanSpoon to tell their customers whether they had last-minute openings. Now, however, UrbanSpoon is launching RezBook, an iPad app and online reservations platform that will allow restaurants to bypass OpenTable and manage their tables and reservation books. Currently, UrbanSpoon is testing the iPhone app with 5 restaurants in the Seattle area, but as the company’s co-founder Ethan Lowry told us earlier today, the company plans to expand this program nationwide over the next few months. UrbanSpoon will first concentrate its marketing on large markets like Seattle and Los Angeles, but anybody with an iPad will soon be able to download the application and use it. The app will be available in Apple’s store within the next few weeks. UrbanSpoon will charge its customers a subscription fee of $99 per month and a $1 fee for every reservation that is made through its system (reservations through UrbanSpoon’s widget will be free). Why IoT Apps are Eating Device Interfaces The application will store its data on UrbanSpoon’s servers. Besides allowing restaurants to manage their reservations, the service will also include a customer relationship management database. Manage Your Restaurant with the iPadAs Lowry told us, the iPad is an ideal device in the restaurant context, as it gives the host far more mobility than the regular large terminal that you can find in most restaurants today. Besides that, Lowry noted, the iPad is also very “cool and sexy,” something that a lot of restaurateurs appreciate. With this move, UrbanSpoon is clearly invading OpenTable’s territory. According to Lowry, restaurateurs never really had an alternative to OpenTable until now. With over 8 million users, UrbanSpoon’s iPhone app is already one of the most popular restaurant-related mobile apps and given that the company offers a cheaper subscription price and runs on relatively cheap hardware, the company, which has been working on this service ever since Apple announced the iPad, has a chance to make a dent in OpenTable’s market. frederic lardinois Related Posts Role of Mobile App Analytics In-App Engagement Tags:#mobile#news#web The Rise and Rise of Mobile Payment Technologylast_img read more

Gajapati’s royal scion joins BJD

first_imgKalyani Devi, scion of the erstwhile royal family of Paralakhemundi in Gajapati district of Odisha, joined the ruling Biju Janata Dal on Tuesday. She was inducted into the party at the residence of Chief Minister and BJD president Naveen Patnaik in Bhubaneswar.Her joining the BJD will strengthen the party in Gajapati district and Berhampur parliamentary constituency, said sources. The BJD might consider fielding her as its candidate from Paralakhemundi Assembly seat or Berhampur parliamentary constituency, the sources said.Ms. Devi’s family had been politically active from before Independence. She is the daughter of former Congress MP from Berhampur, Gopinath Gajapati, who was a member of the ninth and 10th Lok Sabha. He later joined the BJD in 2009.Her grandfather Krushna Chandra Gajapati (1892-1974)played a key role in the formation of Odisha State on linguistic basis and is revered throughout the State. He was the first prime minister of Odisha before Independence and a member of the Constituent Assembly of India. The present day Gajapati district, carved out of Ganjam district, is named after him.“The family of Ms. Devi is well-known for its tradition of social service and her induction will surely strengthen the party organisation,” said BJD’s Gajapati district president Pradeep Nayak. Ms. Devi expressed her gratitude towards Mr. Patnaik for her induction into the BJD and the support extended towards the treatment of her ailing father.last_img read more
