New theory suggests some black holes might predate the Big Bang

first_img(PhysOrg.com) — Cosmologists Alan Coley from Canada’s Dalhousie University and Bernard Carr from Queen Mary University in London, have published a paper on arXiv, where they suggest that some so-called primordial black holes might have been created in the Big Crunch that came before the Big Bang, which lends support to the theory that the Big Bang was not a single event, but one that occurs over and over again as the universe crunches down to a single point, then blows up again, over and over. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The idea is based on the fact that the Earth, and the rest of the known universe is occasionally bombarded with unexplained bursts of gamma rays; something that could, according to Coley and Carr, be the result of primordial black holes running out of energy and disintegrating.Primordial black holes are thought to be of a different type than the regular kind that are formed when a supernova occurs, leaving a void that is filled by the entity that is commonly known as a black hole. Many theorists support the notion that there does exist other types of black holes that were formed in the first “moments” after the Big Bang; black holes that would be smaller and created by the energy of the Big Bang itself. In this new theory, however, Coley and Carr suggest that some of these black holes, if they do actually exist, might have been created by the collapsing universe as part of the Big Crunch, and then somehow escaped being pulled into the pinpoint singularity comprised of everything else. And then, after the Big Bang, they simply assimilated with the newly formed universe. One problem they agree on is that it would likely be impossible to tell the difference between pre and post Big Bang primordial black holes.It’s all purely speculation of course, as no one has ever actually seen a primordial black hole, or even offered much proof that they exist, but it does raise very difficult questions; ones that are impossible for scientists much less casual observers to answer. Questions such as, if the universe contracts, then blows up, over and over, has this gone on forever? Or is it possible that our view of the universe is so limited that we’re only seeing one tiny fraction of it, and thus, any theories or explanations we offer, are little more than guesses. And finally, maybe the hardest one of all; is it possible that the universe actually goes on forever; that it has no boundaries or borders? Which would mean the Big Bang was actually little more than one tiny event going on in one small part of an endless expanse.It’s possible that no matter how long we as a people survive, we’ll never really know the answers to such questions, which might in the end mean, we’ll just have to take our theories on faith.

Coley, arXiv:1104.3796v1 [astro-ph.CO] arxiv.org/abs/1104.3796AbstractWe discuss whether black holes could persist in a universe which recollapses and then bounces into a new expansion phase. Whether the bounce is of classical or quantum gravitational origin, such cosmological models are of great current interest. In particular, we investigate the mass range in which black holes might survive a bounce and ways of differentiating observationally between black holes formed just after and just before the last bounce. We also discuss the consequences of the universe going through a sequence of dimensional changes as it passes through a bounce. © 2010 PhysOrg.com Scientists glimpse universe before the Big Bang Explore furtherlast_img read more

The installations address ongoing concerns –the question of transformation, retrieving the marginal and the play between the mythic and social in the context of gender, body, representation, urban ecologies, violence and visual culture. Public art interventions are an important arena for Chhachhi and she has created several onsite works in the city of Delhi over the last few years.Expressing enthusiasm over this year’s artworks, Volte Art Projects’ founder and director, Tushar Jiwarajka said, “This year’s Volte Art Projects is refreshingly significant and I feel greatly honored for being able to expand our country’s art outlook by joining hands with artists who are not only original but also constantly innovating, breaking the conservative approach towards art with their various forms of subtle and bold expressions.”last_img read more

TMCs Dutta quits as Bidhannagar mayor to decide next move

first_imgKolkata: Trinamool Congress (TMC) legislator and Bidhannagar Mayor Sabyasachi Dutta on Thursday resigned from the civic body post, complaining lack of cooperation from the West Bengal government. Dutta’s announcement came a day after the Calcutta High Court quashed a notification by the Bidhannagar Municipal Corporation’s joint commissioner for convening a councillors’ meeting to move no-confidence motion against him. “I have always worked for the welfare of poor and working class people and would continue to do so till my last breath. I did not get enough cooperation from the state government. As a people’s representative if I am not able to work as per the Municipal Corporation Act, I have no right to hold on to the mayor’s post. Hence, I have tendered my resignation,” Dutta told reporters. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata “I have sent my resignation letter to Corporation Chairperson Krishna Chakraborty, the commissioner and 39 councillors,” he said. When asked whether he would quit TMC or join any other political outfit, Dutta said nothing had been decided in that regard. “It’s not mandatory for me to be in politics. Also, it’s not necessary that I will have to compromise with unethical practices. I have never done that and will not be do so,” Dutta said. Alleging lack of coordination between different departments, Dutta said he was facing hostility as mayor from a section of civic body representatives and TMC leaders involved in illegal constructions and filling up of water bodies in the Rajarhat-Gopalpur area as he was against that. Also Read – Lightning kills 8, injures 16 in state The nearly four-month drama centring around Dutta’s controversial statements about the TMC and his affinity with former TMC leader Mukul Roy, now in the BJP, reached climax with the party recently clipping his wings and asking him to quit, while empowering the municipal corporation’s deputy mayor to take over most of the mayoral responsibilities. Speculations have been rife about Dutta’s political intentions since Roy dropped in at his Salt Lake residence before the elections. The incident was followed by a controversy over a social media post that apparently came from Dutta’s mobile.last_img read more

KVIC bags fresh order worth nearly Rs 750 crore

first_imgTraditional Khadi, it seems, has grabbed the calling card of future i.e. innovation in the recent past. And, it is the effect of innovation and consequent quality maintenance, that Khadi has been bagging many bulk orders from PSUs and government organisations.The flagship store of the Khadi and Village Industries Commission (KVIC), Khadi Bhawan at Connaught Place in New Delhi has bagged order worth over Rs 7.03 crore from the Oil India Limited (OIL), in the form of Khadi gift coupons for its 14,064 employees. The OIL agreed to gift Khadi coupons of Rs 5,000 to each of its 14,064 employees in its all units across the nation. The employees, however, would be able to purchase Khadi and Village Industries products worth Rs 6,500 from the coupon of Rs 5,000. The coupons, which had already been delivered, could be redeemed throughout the year at all Departmental Sales Outlets. Also Read – Add new books to your shelfIn another order, the Bureau of Energy Efficiency (BEE) had also ordered 800 gift coupons in the denomination of Rs 1,000 for its 800 staff. These coupons have already been delivered and the 800 BEE staff could also purchase Khadi and Village Industries products worth Rs 1,300 from the coupon of Rs 1,000. KVIC Chairman Vinai Kumar Saxena said that such huge orders from government and PSUs not only increase the income of the artisans – pivotal in the growth of Khadi sector but also inspire new entrepreneurs to associate with Khadi with better job avenues. “Such orders from OIL and BEE will certainly make a compounding effect on the livelihood of Khadi artisans and will certainly create more jobs by adding thousands of new artisans in KVIC’s kitty,” he said, adding, “These orders will certainly create more employment and subsequently raise the income of the existing artisans. It would also pave the way for KVIC for more convergence with different ministries and Public Sector Units.” Also Read – Over 2 hours screen time daily will make your kids impulsiveIt may be noted that many government organisations in the recent past, had shown its keen interest in promoting eco-friendly Khadi products. In January this year, in a quick response to the instructions issued by the Ministry of Railways to procure linen items from the KVIC – the North Western Railways (Jaipur), North Central Railways (Allahabad) and Northern Railways (Delhi) had given order of approximately Rs 12.40 crore to the KVIC, for supply of Khadi duster and green/red flags. Later, on March 25, 2019, the KVIC further bagged order to supply DT and duster worth Rs 1.25 crore from Rail Coach Factory at Kapurthala. On the same day, the KVIC received the order to supply duster worth Rs 1.65 crore from North-West Railways Jaipur. In what may be a trendsetter for educational institutions, on March 5, 2019, KVIC had bagged order of different varieties of Khadi Silk’s robe with Angawastram from Indira Gandhi National Open University worth over Rs 21 lakh.last_img read more

The vehicle made its debut in January at CES 2016 in Las Vegas, and was given the OK by the Nevada Governor’s Office of Economic Development (GOED) to start testing in the state this year.Related: How Drones Will Change Your BusinessThe company doesn’t have FAA approval just yet, but EHang’s partnership with the governor’s office and the Nevada Institute for Autonomous Systems (NIAS) has made it possible for the vehicle to be flown at the Nevada UAS (unmanned aerial systems) test site.“EHang’s selection of Nevada to test its people-carrying drone marks a thrilling addition to the innovative companies testing throughout our state to advance the commercial drone industry. I personally look forward to the day when drone taxis are part of Nevada’s transportation system,” GOED’s Aerospace and Defense Industry Specialist Tom Wilczek said in a statement about the agreement.Related: Scientists Are Training Drones to Find Lost HikersThe Ehang 184 looks a little like the nose of a helicopter, but instead of wings on the top, it has four legs with two propellers each. The vehicle runs on a battery and weighs 440 pounds, and when it gets into the air at about 11,500 feet, it can fly for roughly 23 minutes at a little over 60 mph.So who knows?

What you can do if your browser uses too much Memory

first_imgWhat you can do if your browser uses too much Memory by Martin Brinkmann on September 18, 2018 in Firefox – 97 commentsWhile web browsers were never the leanest applications memory-wise, memory usage of web browsers seems to have exploded in recent time.It is not uncommon anymore that browsers such as Chrome or Firefox cross the two or three Gigabyte memory mark; a growing number of users is concerned about the memory use of browsers. But, should they be concerned?This guide provides you with instructions on taming a browser’s memory usage. It also answers whether you should be worried about memory use.Is high memory use a problem?Whether high memory usage is a problem or not depends entirely on whether it impacts the performance of the system you are using. My main PC has 32 Gigabytes of RAM and if a browser uses two or three Gigabytes, it is not really a problem as there is plenty of RAM available.The situation is different if a browser uses two or three Gigabytes on a system with just three or four Gigabytes of RAM. If there is not enough RAM, Windows starts to use the disk more as a cache of sorts and that slows down certain operations.Browsers may discard tabs when system memory runs low; Chrome does so for instance.Users and admins who encounter this situation may do something about it. Below is a list of suggestions on how to deal with high RAM usage on computers who don’t have plenty installed:Option 1: Install more RAMThe only option that costs money. It is very effective at combating the effects of high RAM usage on PCs.There are some caveats (besides money):It works only on devices with free RAM banks or support for larger RAM modules.You need to check the motherboard manual to find out about supported specifications.You may also want to check the installed RAM if you plan to add modules without removing existing ones.You need to run a 64-bit operating system.You need to install the memory by yourself or pay someone to do so.How much does it cost? There is quite the variety available when it comes to RAM. Two 4 Gigabyte memory modules start at about $60 depending on where you look and which brand you purchase. A single 4 Gigabyte memory module starts at around $40.You can find out how much RAM is installed on your PC with the shortcut Windows-Pause. Check the “installed memory (RAM)” listing on the window that opens.Option 2: limit your browsingWhile it is certainly great that you can open one-hundred-and-five tabs in Google Chrome or Mozilla Firefox at the same time, doing so increases memory usage.It is usually the case that you don’t interact with all open tabs during every browsing session. Closing tabs in the browser frees up memory.If you want to preserve a resource, add it to the bookmarks. You may also use the following extensions to deal with high RAM usage:Lazy Load tabs in ChromeSave Tabs in Firefox with Session BossTabs Limiter for Google ChromeChrome comes with a handy Task Manager that you may open to find out which websites, resources, or browser extensions use the most RAM. Facebook alone uses more than 500 Megabytes in the example above.Firefox users may check about:memory or about:performance, but these are not as easy to analyze as Chrome’s Task Manager.Option 3: check installed browser extensionsSome browser extensions may increase memory use of the browser significantly. You can use the Task Manager in Chrome to find out about RAM usage of extensions.If you do use a different browser you may need to disable all extensions to find out how much memory they require. If you notice that extensions use a large chunk of memory, you may want to enable them one by one to find out which use the most memory.You may not want to disable certain extensions even if they use a lot of memory. Some extensions are not needed all the time though. If you use a video downloader, you may use it only occasionally so that you might want to consider disabling it and turning it on only when it is needed.Option 4: Preferences that may helpWeb browsers may support options to reduce the overall memory usage of the browser. Firefox users can change the number of content processes that the browser uses to reduce the browser’s memory usage.Limiting content processes may impact stability of the browser (not necessarily) but it will certainly reduce the memory use of it.Firefox users may change advanced configuration options, for instance by turning off out-of-process extensions to save another process.Google Chrome users can enable the browser’s process-per-site feature to limit Chrome processes as well.See also:How to tame Google Chrome’s memory useWhat you do when Firefox uses too much memoryClosing WordsIt is almost certain that memory usage will grow in coming years. Web applications demand faster browsers and more memory to run, and browsers may introduce new features or functionality that increases memory usage as well.While there is certainly room for improvement, memory usage will only go up in the coming years.Now You: have additional tips? Feel free to share them in the comment section below.SummaryArticle NameWhat you can do if your browser uses too much MemoryDescriptionWhat can you do if your web browser uses too much memory?

That’s a question that Mozilla tried to answer in a recent Shield experiment that it ran.The traditional method to download files using web browsers is to save them to the local system. One reason for that is that web browsers don’t include options to store files directly in the cloud.Extensions may add functionality to save files directly to the cloud. Google’s Save to Google Drive extension for Google Chrome has more than 5.6 million users, but that is the exception.The main question that Mozilla tried to answer was whether Firefox users would like to see an “save to cloud storage” feature in the browser.The goal of the Cloud Storage experiment is to evaluate whether there is a market fit for integrating the Firefox download feature with one of the existing cloud storage providers (e.g. Dropbox, Google Drive).Mozilla selected 1% of the Firefox 60+ release population that used the en-US locale for the study. A prompt was displayed to all users selected for the study so that users could decline the experiment.Firefox users who took part in the study saw an updated download panel that would include options to save the download to one of the connected cloud storage providers.Firefox users could push the file to the cloud storage immediately or download it to the local system instead.Study participants could move local downloads to the cloud with a right-click on the downloaded file in the Firefox download panel and the selection of one of the connected providers.Icons were attached to downloads saved to cloud storage providers to distinguish them from local downloads.Firefox users who took part in the study could select a cloud provider as default storage to always save downloads to the cloud.The key findingsGoogle Drive and Dropbox were the two most used cloud storage services followed by iCloud and Microsoft OneDrive.Mozilla asked all participants questions and about 70% of them said that they would “choose to keep” the feature and 10% of study participants switched the default download behavior to a cloud provider.The “move” feature that allowed users to move local downloads to a selected cloud provider was not used by many participants.Closing WordsIt remains to be seen how (and if) Mozilla will react on the findings of the study. Will we see the save to cloud storage option integrated into Firefox natively in the future?Mozilla did reveal that the integration may open up new business opportunities.Now You: Would you find the option useful?SummaryArticle NameMozilla ran a cloud storage download experiment in FirefoxDescriptionIs it a good idea to integrate options to save Internet files directly to cloud storage providers?

Sen Josh Hawleys New Bill Aims To Make Autoplay Videos Endless Scrolling

It has the same kind of addictive qualities that keep people in Las Vegas hooked. Other examples are removing stopping cues. So if I take the bottom out of this glass and I keep refilling the water or the wine, you won’t know when to stop drinking. That’s what happens with infinitely scrolling feeds.”Hawley agrees with the assessment, pointing out that the technology industry is embracing a business model that relies on addiction.”Too much of the ‘innovation’ in this space is designed not to create better products, but to capture more attention by using psychological tricks that make it difficult to look away,” Hawley said in a report from The Verge.The Darker Side Of The BillIn a piece on Reason, Peter Suderman pointed out that empowering federal agencies to regulate every detail of social media companies seems to be “a wild misuse of federal power.” It’s easy to imagine, he explained, agencies or individuals abusing this bill to punish, reward, and generally control companies.Ultimately, critics are noting that the SMART Act is too controlling, treating Internet users with kid gloves. Instead of trusting individuals to regulate themselves online and on social media, the bill operates with the belief that the government or legislation needs to step in.

The Bali head of Indonesia’s Ministry of Communications, Nyoman Sujaya, confirmed that data will be off for 24 hours following an agreement with telecommunications companies, according to AP.Internet access related to hospitals, security, the digital economy, and cyber crime will be unaffected, according to Berita Satu. The shut off will begin at 6 a.m. on Saturday, and finish at the same time on Sunday. It’s reportedly the first time the internet has been shut off the for the holiday, although religious and government leaders made the same request last year.“Let’s rest a day, free from the internet to feel the calm of the mind,” head of the Indonesian Hinduism Society in Denpasar, Gusti Ngurah Sudiana, said.While mostly a Hindu holiday, the Day of Silence also applies to non-Hindus and tourists, the latter of which especially will have to refrain from their selfie-taking for one day.[embedded content]last_img read more
