But for 70 years, cosmologists have never observed dark matter, and the lack of direct observation has created skepticism about what is really out there.center_img Lately, some scientists have turned the question around, from “is dark matter correct?” to “is our standard theory of gravity correct?” Most recently, Fermilab scientists Scott Dodelson and former Brinson Fellow Michele Liguori demonstrated one of the first pieces of theoretical evidence that an alternative theory of gravity can explain the large scale structure of the universe. “To definitively claim that dark matter is the answer, we need to find it,” Dodelson explained to PhysOrg.com. “We can do this in one of three ways: produce it in the lab (which might happen at Fermilab, the soon-to-start LHC, or ultimately the International Linear Collider), see a pair of dark matter particles annihilate and produce high energy photons (there are about a half dozen experiments designed to look for this), or see a dark matter particle bump a nucleus in a large underground detector (again, about 10 experiments are looking for this). Until one or more of these things happen, skeptics are still allowed. … After they happen, skeptics will become crackpots.”Although cosmologists have never directly observed dark matter, they have many good reasons for not giving up hope. The ways that galaxies rotate and starlight bends (gravitational lensing) stray from predictions based on visible matter. Further, the formation of large cosmic structures (such as galaxies and galaxy clusters) would have required significantly large matter perturbations when the Universe was less than a million years old that simply don’t exist in a theory of general relativity before “tacking on” dark matter.“It is extremely important to see how well a no-dark-matter cosmology does,” said Dodelson. “[In the standard theory,] we are asking the community to believe in the existence of a particle that has never been seen. We have to be damned sure that you can’t explain the universe without this huge leap. Our Figure 1 [see citation below] illustrates that, in standard gravity, a no-dark-matter model does not do well at all.”While altering the theory of gravity may seem like pulling the rug out from under a century of observations and pain-staking calculations, an alternative theory may simply be “more correct” than today’s standard theory. Just as Einstein’s theory was “more correct” than Newton’s because it improved upon the older one by noticing more specific details (e.g. extraordinary masses and speeds), a new alternative theory may only drastically change gravity at certain scales. The light from galaxies in the background has been warped and “arced” by the galaxy cluster Abell 1689 in the foreground, and perhaps with some help by either dark matter or a stronger type of gravity on this large scale. Image Source: NASA, N. Benitez (JHU), T. Broadhurst (Racah Institute of Physics/The Hebrew University), H. Ford (JHU), M. Clampin (STScI),G. Hartig (STScI), G. Illingworth (UCO/Lick Observatory), the ACS Science Team and ESA. “Perhaps a fundamental theory of gravity which differs from general relativity on large scales can explain the observations without recourse to new, unobserved particles,” wrote Dodelson and Liguori in their study published in Physical Review Letters. “Now more than ever before, there are very good reasons to explore this idea of modifying gravity. For, the case of dark energy also hinges on the assumption that general relativity describes gravity on larges scales. Dark energy is even more difficult to explain than dark matter, so it seems almost natural to look at gravity as the culprit in both cases.”The new theory (or groundwork for it) under investigation would be Jacob Bekenstein’s relativistic covariant theory of gravity (TeVeS), published in 2004. Bekenstein based his theory on a modified version of Newtonian theory from the early ‘80s, dependent on gravitational acceleration and called modified Newtonian dynamics (MOND) by its founder, Mordecai Milgrom. “MOND, the original theory on which TeVeS is based, was already quite successful at explaining galactic dynamics (even better, in some cases, than the dark matter paradigm), but it failed completely at explaining other observations—gravitational lensing in particular,” explained Liguori. “For this reason, it couldn’t be considered a real alternative to dark matter. Bekenstein’s theory, by generalizing MOND, retains its good features while overcoming its main problems at the same time. This makes TeVeS a much more interesting theory than MOND. It is then worthwhile (and necessary) to test TeVeS’ predictions in detail and compare them to the standard dark matter paradigm to see if TeVeS can be a viable alternative.”Dodelson and Liguori find Bekenstein’s theory intriguing in this context because, for one, the gravitational acceleration scale in the theory is very close to that required for the observed acceleration of the Universe. The scale is also very similar to that proposed in “post hoc” theories such as dark energy. Even more interesting is the fact that the origins of Bekenstein’s theory had nothing to do with cosmic acceleration. But the feature of Bekenstein’s theory that Dodelson and Liguori focus on most is that the theory—unlike standard general relativity—allows for fast growth of density perturbations arising from small inhomogeneities during recombination. Building on this finding from scientists Skordis et al. earlier this year, Dodelson and Liguori have found which aspect of the theory actually causes the enhanced growth—the part that may solve the cosmological structure problem.The pair has discovered that, while Bekenstein’s theory has three functions which characterize space-time—a tensor, vector and scalar (TeVeS)—it’s the perturbations in the vector field that are key to the enhanced growth. General relativity describes space-time with only a tensor (the metric), so it does not include these vector perturbations.“The vector field solves only the enhanced growth problem,” said Dodelson. “It does so by exploiting a little-known fact about gravity. In our solar system or galaxy, when we attack the problem of gravity, we solve the equation for the Newtonian potential. Actually, there are two potentials that characterize gravity: the one usually called the Newtonian potential and the perturbation to the curvature of space. These two potentials are almost always very nearly equal to one another, so it is not usually necessary to distinguish them. “In the case of TeVeS, the vector field sources the difference between the two,” he continued. “As it begins to grow, the difference between the two potentials grows as well. This is ultimately what drives the overdense regions to accrete more matter than in standard general relativity. The quite remarkable thing about this growth is that Bekenstein introduced the vector field for his own completely independent reasons. As he remarked to me, ‘Sometimes theories are smarter than their creators.’”Dodelson and Liguori see this solution to large structure formation as an important step for a gravity theory based on baryon-only matter. Other problems that their theory (or any alternative theory) will have to confront include accounting for the mismatch in galaxy clusters between mass and light. Also, the theory must conform to at least two observations: the galaxy power spectrum on large scales, and the cosmic microwave background fluctuations, which correspond to baby galaxies and galaxy clusters. “As Scott says, until dark matter will be observed, skeptics will be allowed,” said Liguori. “Despite the many and impressive successes of the dark matter paradigm, which make it very likely to be correct, we still don’t have any final and definitive answer. In light of this, it is important to keep an eye open for possible alternative explanations. Even when, after the analysis, alternative theories turn out to be wrong, the result is still important, as it strengthen the evidence for dark matter as the only possible explanation of observations.”Citation: Dodelson, Scott and Liguori, Michele. “Can Cosmic Structure Form without Dark Matter?” Physical Review Letters 97, 231301 (2006).By Lisa Zyga, Copyright 2006 PhysOrg.comlast_img read more

In response, computer security company RSA has developed a technique that it claims can prevent hackers from gaining access to user passwords on servers.

When a user logs into the system, the password is split into two separate strings, each of which is sent to one of the password servers. There, it is joined, in random fashion, with the half of the password stored on that server to build a new string. To verify the password, the two strings on each server are compared to one another. With this scheme, a hacker would be forced to access both servers in order to gain access to user passwords. And, this process could be further complicated if each server were to run a different operating system. RSA says that to make things even more difficult for hackers, systems administrators could periodically refresh the random half of the strings, which would force those seeking entry to crack both servers within a shorter time frame. Using DCP would make stealing passwords from website servers significantly more difficult; however, it wouldn’t prevent passwords from being stolen directly via malware on users’ computers. To address that threat, RSA recommends that users use different passwords for their various accounts in order to limit the degree of damage that could potentially result if one of them is stolen.last_img read more

Proc Natl Acad Sci USA 112(25):7635-7638. (Phys.org)—Today’s photonic and plasmonic devices – the latter based on surface plasmons (a coherent delocalized electron oscillations that exist at the interface between metal and dielectric) and combining the small size and manufacturability of electronics with the high speeds of optics – need the ability to guide surface electromagnetic waves around disorder, such as ultrasharp corners and bumps, without disturbing the wave amplitude or phase. That being said, achieving this preservation of phase and amplitude has been difficult due to the fact that light momentum must be conserved in a scattering event (that is, when electromagnetic radiation or particles are deflected or diffused by localized non-uniformities in the medium through which that radiation is passing). However, scientists at Zhejiang University in Hangzhou, China, Nanyang Technological University, Singapore, and Massachusetts Institute of Technology created (so-called invisibility) cloaks based on specifically-designed nonmagnetic anisotropic, or directionally dependent, metamaterials that achieve nearly ideal transmission efficiency over a broadband frequency range. The researchers state that results the viability of applying transformation optics – which applies metamaterials to produce spatial variations, derived from coordinate transformations, which can direct chosen bandwidths of electromagnetic radiation – to plasmonic circuits, and in so doing could lead to high-performance, large-scale integrated photonic circuits. Zhang lists the three key insights and innovations the researchers used to address these challenges: Fig. 3. A Gaussian-shaped pulse propagates on the patterned metal. A point source (port 1) generates the pulse at 0 ns. The bandwidth of the pulse is 6 GHz, and the center frequency is 3 GHz. The magnetic field distributions for three cases [(A) the corner cloaks, (B) the carpet cloak, and (C) the straight waveguide reference] are plotted to show the propagation of the pulse at five equivalent temporal sampling points. Credit: Xu S, et al. (2015) Broadband surface-wave transformation cloak. Proc Natl Acad Sci USA 112(25):7635-7638. The paper also discusses the interesting point that transformation optics effectively warps electromagnetic space in a manner analogous to how gravity curves space in general relativity. “The macroscopic performance of warping electromagnetic space can be expressed by constitutive parameters in a new coordinate system.” (Constitutive parameters describe the desired or actual performance and responses of a metamaterial.) Specifically, Zhang notes, these new constitutive parameters can be isotropic, anisotropic, or bianisotropic (that is, identical in all directions, directionally dependent, and asymmetrically anisotropic, respectively), and might be realized by metamaterial design and fabrication. “With this procedure,” he emphasizes, “we’d have the ability to operate and control electromagnetic waves in exactly the way we want.”Another important point in the paper was overcoming the issue with previous cloaks requiring that the phase velocity of light being guided around the cloaked object had to exceed the vacuum speed of light. “Cloaking from free-space electromagnetic waves suffers from narrow bandwidth because the phase velocity,” which depends on both frequency and medium, “is required to be greater than the speed of light. In our work, given that the surface wave propagates much more slowly than the speed of light, we can avoid superluminal propagation in free space cloaking.”Finally, the key result being reported is that unlike topological electromagnetic surface states, in the new approach phase is preserved when surface waves are perfectly guided by the cloaks. “Sharp bending of surface waves was previously achieved only in topological electromagnetic edge states,” Zhang tells Phys.org. “Because the required materials generally are magnetic, it suffers from narrow bandwidth. In our work, however, the use of anisotropic non-magnetic materials and transformation optics ensure the phase preservation of surface waves.”Chen says that the scientists plan to extend their experimental demonstration from microwaves to higher frequencies, including infrared and visible light. “This may push our work much closer to practical application. Moreover, scientists have extended the concept of transformation beyond electromagnetic fields to other types of physical fields, such as heat, diffusive light, acoustics, and static fields. “No matter which kind of physical field it is, the fundamental point is to control the propagation of the waves and the distribution of the field,” Chen concludes. “Our work can therefore be extended to many other areas of research.” ● Overcoming the challenge of momentum mismatch by adopting strict transformation optics with anisotropy in the design – a strategy that can also work for ultrasharp corners and bumps● Realizing broadband performance by employing an area-preserving coordinate transformation, which can produce non-magnetic constitutive parameters for a surface plasmon polariton (SPP –an electromagnetic excitation existing on the surface of an appropriate metal) wave cloak● Experimentally demonstrating SPP cloak performance by designing a layered metamaterial composed of microwave ceramic plates and low-permittivity foam with subwavelength periodicity (in which the periodicity of the metamaterial is much smaller than the wavelength of the electromagnetic wave being cloaked) In terms of likely applications of transformation optics in plasmonic circuits and high-performance, large-scale integrated photonic circuits, Zhang points out that over the last few decades, surface plasmons have attracted substantial research effort because they offer the potential for merging electronics and photonics on the same chips by reducing the size of photonic components to the nanoscale. “Therefore, plasmonics is a key technology for interconnects – but guiding light around sharp bends is one of the main limiting factors for plasmonics.” (The other limiting factor is loss, which also occurs in straight waveguides.) “In this study we made plasmonic technology the main motivation and tried to solve the scattering issue during wave propagation across disorder. In short, our research focuses on scattering-free guiding.”The paper also mentions other applications resulting from switching from free-space electromagnetic waves to surface electromagnetic waves. “Free-space electromagnetic invisibility cloaks and other free-space devices based on transformation optics have the property of superluminal propagation,” Zhang explains. “This will fundamentally introduce narrowband.” (Narrowband refers to signals over a narrow range of frequencies.) “However, if we can transition from free-space waves to surface waves, we can take slow waves into consideration and achieve broad bandwidth.” As a result, scattering-free surface plasmon polariton wave guidance can be used in a wide range of applications, such as plasmonic phase modulators (which slows plasmons, leading to what is essentially an optical switch) and beam steering changing the direction of an electromagnetic signal). Prof. Hongsheng Chen at Zhejiang University and Prof. Baile Zhang at Nanyang Technological University discussed the paper that they and their colleagues published in Proceedings of the National Academy of Sciences. “In overcoming narrow-band light transmission limitations and disorder-related phase disturbances in guiding surface electromagnetic waves, the fundamental challenge lies in realizing broadband scattering-free propagation – that is, how to match momentum when the surface wave propagates before or after the disorder in a broad band,” Chen tells Phys.org. In other words, surface waves suffer from scattering loss as a result of momentum mismatch when encountering sharp corners or other irregular disorders.A related obstacle was demonstrating – both theoretically and experimentally – broadband surface electromagnetic wave guidance around ultrasharp corners and bumps with no perceptible changes in amplitude and phase. “Theoretically, transformation optics can potentially provide a solution to guide the surface wave by warping the electromagnetic space around ultrasharp corners, so that electromagnetic surface waves will be deceived as if they were still propagating along a flat surface without any corner,” Chen explains. However, he adds, since this generally requires both electric and magnetic anisotropic materials and is therefore difficult to implement, the main theoretical challenge in cloaking disorders is to design a feasible coordinate transformation with anisotropic parameters. “Experimentally,” Chen continues, “the main challenge is designing and implementing a feasible non-magnetic metamaterial that meets the parameter requirements derived from transformation optics, because a stable magnetic response is difficult to realize over a broad frequency band.” A third fundamental issue facing the researchers was the design of inhomogeneous metamaterials that control light. “Realizing a continuous inhomogeneous metamaterial is very difficult in practice,” Chen points out. “Generally, we can use artificial metamaterial units with different subwavelength geometries, similar to the atoms in natural media, to realize inhomogeneous electromagnetic parameters – but this requires very fine nanofabrication procedures.” More information: Broadband surface-wave transformation cloak, Proceedings of the National Academy of Sciences (2015) 112(25):7635-7638, doi:10.1073/pnas.1508777112 Journal information: Proceedings of the National Academy of Sciences © 2015 Phys.org Engineers give invisibility cloaks a slimmer design Explore further This document is subject to copyright.

It is not very difficult to implement as their technology is great,” the senior official pointed out. Earlier in a meeting with the department, the aggregators had claimed that the surge price is calculated by an algorithm when there is a demand-supply mismatch.

first_imgKolkata: In a unique initiative, Calcutta Medical College and Hospital (CMCH) authorities have decided to organise ‘Puja Parikrama’ — where the children undergoing treatment at various departments in the hospital would be taken to various Puja pandals.According to the hospital sources, apart from the children suffering from Thallassemia many others at Oncology and Pediatric Medicine would be given an opportunity to see the idols at various Puja pandals. The children, who are in the hospital for over 5 months, hardly get any scope to step out of the four walls of the hospital room. During Durga Puja, when the entire state celebrates the home coming of Goddess Durga with her entourage from her abode, people indulge in pandal hopping wearing new dresses. But many children who are on hospital beds find it difficult to remain confined within the hospital during the Puja days. Keeping this in mind, CMCH has come up with the unique idea of arranging a ‘Puja Parikrama’ where children will be able to go out and enjoy pandal hopping, will have own fun their outside the hospital.

It is better to learn to build a versatile and timeless wardrobe first and then bring in your own twists.last_img read more

But as an actor, my job is to follow what the director has visualised for the film. I just did that,” she added.last_img read more

first_imgIn 1997, The National Aeronautics and Space Administration was on the receiving end of a lawsuit filed by three Yemenis who claimed the Red Planet was theirs and NASA was exploring it without authorization or proper consent from its rightful landowners. “Sojourner and Pathfinder, which are owned by the United States government, landed on Mars and began exploring it without informing us or seeking our approval,” the wronged men declared for the Arabic-language weekly newspaper Al-Thawri, several days after they had filed an official complaint to the country’s prosecutor general in Sana’a, Yemen.Pathfinder and Sojourner at JPL in October 1996, being ‘folded’ into its launch position.“We inherited the planet from our ancestors 3,000 years ago,” the men declared.

Photo by ESA CC BY-SA 3.0“It’s a ridiculous claim,” Brian Welch, at that time NASA director of Media Services, told CNN. “Mars is a planet out in the solar system that is the property of all humanity, not two or three guys in Yemen.”Welch added that in accordance to the 1967 United Nations International Space Treaty, no man nor country can claim ownership over land in outer space.The Pathfinder air bags are tested in June 1995.NASA began their space exploration program in the late 1950s, and after a few successful and extremely costly landings on the Moon, they set their sights towards the next plausible destination. Following NASA’s first successful Mars flyby with Mariner 4 in 1964, the race to be the first nation to land a probe on the planet’s surface was on. Both the U.S. and the U.S.S.R. began to develop probes that could scout Mars’ atmosphere.In 1971, the first ever spacecraft touched down on the planet’s scorching-hot surface. This was the Soviet Mars 3, which stopped transmitting 20 seconds after landing.Four years later, NASA hit the jackpot with the Viking Mission. The 1,400 images transmitted by the two landers are archived in the NSSDC image catalog. Perhaps Ismail, Kahlil, and al-Umari were too young to get worked up about these earlier transgressions, not to mention the several failed lander missions.Mars Pathfinder panorama of landing site taken by IMP.It was July 4, 1997, when the unmanned spacecraft Mars Pathfinder, the base station later renamed as the Carl Sagan Memorial Station, landed on the planet. It released the free-ranging robotic Sojourner rover to roam the planet and start a thorough analysis of the rocks soil in the area.In the space of just a few weeks both the lander and the rover combined sent millions of pieces of information back to Earth — including thousands of pictures, as well as data about Mars’ atmosphere, such as wind speeds, and air and soil temperatures.1990s illustration of Mars atmospheric entry.The data collected turned out to be of great significance, and the world was glad to hear NASA’s conclusion that Mars was at one time a wetter world and presumably a much friendlier place to possibly sustain life as we know it.These three men from Yemen, it turns out, were not so happy about it, nor keen to let a “trespasser” roam around and reveal valuable information to the public about their private estate.Sojourner rover on Mars.In short, their claim was built around the mythologies of two ancient and long-lost civilizations, the Himyarites and the Sabaeans, that existed several millennia before the age of Christ and the Roman Civilization.According to these beliefs, the two ethnic groups raised a temple to each of the seven planets visible with the naked eye. Did the claimants interpret this as meaning that their ancestors were celestial beings? Who knows. CNN joked that “There was no word on whether they had paid the appropriate inheritance taxes.”NASA Apollo moon landings conspiraciesIsmail, Kahlil, and al-Umari were of the opinion that they are direct descendants of the rightful owners of the Red Planet.

first_img Advertisement Aaron Rodgers doesn’t catch much heat from the football media. The conventional media narrative is that Rodgers has been carrying a weak Green Bay roster on his back.In a league where the media is quick to evicerate quarterbacks, Rodgers get press coverage like Pope Francis on his U.S. tour. Tony Romo gets ruthlessly picked apart, even though he has 25 comeback wins in his career compared to Rodgers’ 10.Today, Colin argued the idea that Rodgers is leading a talent deficient roster doesn’t hold up. Pro Football Focus rated the Packers roster as the second best in the league.There’s no question Rodgers is a sure fire, first ballot Hall of Famer. But, for some reason, the media is terrified to point out Rodgers may have some some flaws. “People are so reluctant to say ‘He holds the ball too long. He’s not the greatest leader. He can be moody and cocky. He’s had wide receivers and tight ends criticize him publicly. Even Peter King, who I love. Everybody is so reluctant to criticize him.”The reality is, the Packers have one of the best GM’s in Ted Thompson. A talented roster. They’ve drafted well. They play in a weak division. But, other than the 2010 Super Bowl run, the Packers have lost in either the Wild Card or Divisional rounds of the playoffs in 4 of 5 years.Aaron Rodgers is great, but the idea that any criticism of him is off limits is insane.last_img read more

first_imgColin doesn’t like hypotheticals, but when it comes to speculating about the future of Tom Brady in New England, he can’t help himself. Brady has put up another MVP-type season, but played poorly against the Texans in the Divisional Round.In his last two postseason games, Brady is completing 47.9% of his passes, has more touchdowns than interceptions (3 TD, 4 INT), and a passer rating of 61.3. At some point, the 39-year old Brady and the Patriots are going to part ways, the question is, when?Colin thinks that if Brady plays poorly and the Patriots lose this weekend, conversations will start taking place between Bill Belichick and owner Robert Kraft about Brady’s future, and if it’s time to make the organizational shift to Jimmy Garoppolo as the future of the Patriots franchise.“If Pittsburgh wins this game and Brady’s average, you’re darn right Kraft and Belichick are having that ‘let’s have lunch and talk.’ You’re darn right they are, and I don’t blame them one bit.” Advertisement Colin cited Belichick’s long history of moving on from players a year early, rather than a year late, as a reason the move could happen. He doesn’t see why his handling of the Brady situation will be any different.With Belichick, there are no sacred cows, only pieces of his master formula based on getting valuable assets for players before they fall off the cliff. This includes Tom Brady.“Bill Belichick has never given us one moment that makes you think he deeply cares about his players. They’re retail, baby. He gets rid of guys a year early, not a year late. If you think he’s gonna get held hostage by a situation, it’s not gonna happen.”Colin pointed out that there isn’t a quarterback in football that’s more ready-made to assume the mantle from Brady than Garoppolo.  And while Brady may have some good years left, at 39, he doesn’t have many. Despite putting up MVP numbers this season, Brady won’t play forever. Decision time is coming sooner than one might think.“The end comes very quickly in pro sports.”Belichick never waits until the end in sight, he trades players when it’s just around the corner.Does a loss to the Steelers speed up Tom Brady’s exit from the Patriots? pic.twitter.com/BeSJqcfe57— Herd w/Colin Cowherd (@TheHerd) January 17, 2017last_img read more

He’s been begging for the release of unedited sparring session videos to tell the whole story.Well, UFC President Dana White finally obliged and posted a video of the knock down, along with another sparring video to his Instagram account, and they don’t back up Malignaggi’s claims.Here’s the much discussed knockdown.

Carson Wentz will need to learn to run less to realize his NFL potentialToday, Philly fans were devastated today when it was confirmed that MVP candidate Carson Wentz will miss the rest of the season with a torn ACL suffered on a scramble against the Rams.Wentz has dazzled fans with his Houdini-like escapability and knack for moving the chains with his legs in crucial spots, but Colin believes that Wentz will have to discipline himself to win almost exclusively from the pocket to fulfill his full NFL potential and endure over time. Big Ben has never gotten the credit he deservesBig Ben clinched another AFC North title with a ridiculous 500-yard passing performance against the Ravens, but even though he’s won multiple Super Bowls and put up massive stats over an absurdly long period of time, he’s been overshadowed at every point his career by other quarterbacks who with more national appeal.Early in his career, Roethlisberger was overshadowed by Peyton Manning and Tom Brady, and now he’s taken a back seat to a new crop of young QB’s that have grabbed the spotlight.Sure, he’s never hosted SNL, and doesn’t have massive endorsement deals, but his on-field body of work is as good as anyone not named Tom Brady, and deserves to be acknowledged.last_img read more

From second hand accounts of random kindness to strangers, to a video of the John Wick star giving up his seat on the NYC subway to a female passenger, Reeves is the opposite of the self-centered movie star stereotype. Advertisement Instead of leaving everyone hanging and getting himself home, Keanu decided to look out for the team and booked a van to L.A. for himself and other stranded passengers. What ensued was a good old fashioned road trip and a bunch of random people riding with Reeves as he read aloud some facts about Bakersfield and hung out like a regular guy.One of the passengers filmed the roadie filmed and posted some of the best parts to Twitter, including a pit stop for burgers.
