Gravity waves could hold key to supersymmetry

first_img Citation: Gravity waves could hold key to supersymmetry (2008, November 5) retrieved 18 August 2019 from https://phys.org/news/2008-11-gravity-key-supersymmetry.html (PhysOrg.com) — “In Geneva,” Anupam Mazumdar tells PhysOrg.com, “there is a big effort to discover supersymmetry particles at the Large Hadron Collider. But that is not the only way to find these particles. We should also be able to see supersymmetry in the sky through the observation of gravitational waves.” Mazumdar, a physicist at Lancaster University in Britain, worked with Alex Kusenko at the University of California, Los Angeles to simulate what kind of frequency distribution would result from the fragmentation of unstable scalar condensate. The two say that a number of devices, including the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), the Laser Interferometer Space Antenna (LISA) and the Big Bank Observer (BBO), would be able to detect the gravitational waves they describe in “Gravitational waves from fragmentation of a primordial scalar condensate into Q-balls,” which has been accepted for publication in Physical Review Letters. Supersymmetry is speculated to go beyond the standard model of physics to introduce particles that solve some of the problems that cannot be solved using only the particles that have been observed thus far. In supersymmetry, the standard particles we are familiar with have superpartners that differ from the standard by half a unit of spin. For example, the superpartners of standard model fermions are s-fermions. “The gravity wave is fundamental to theory from Einstein,” Mazumdar says. “But we have not yet seen it in the frequencies described. However, primordial inflation is one of the many cosmic sources that could produce these waves.” The gravitational waves described by Mazumdar and Kusenko begin as a condensate formed in the early universe of s-fermions. “At a certain point,” Mazumdar explains, “the condensate starts oscillating due to the presence of scalar, s-fermion, masses, whose masses are roughly determined by the scale of supersymmetry breaking. Due to the inherent nature of quantum corrections the condensate is not absolutely stable and fragments during the coherent oscillations. The fragmentation process leads to the formation of non-topological solitons, known as Q-balls. Since the fragmentation process is so violent and anisotropic, it excites gravity waves.” These waves, he says, have an amplitude and frequency detectable by LIGO.Mazumdar says that, while many hope to find evidence of supersymmetry when the LHC is fully operational, it is not the only place where one can look for the signs of supersymmetric particles. Besides, he points out, evidence of supersymmetry may not be found at the LHC. Looking to the cosmos, then, would be another option. This is where the sophisticated cosmological observation devices – especially LIGO – come in. “Our model shows frequencies exactly where LIGO is sensitive,” he says. “We also show a place where the frequency would be distinguishable from binaries, black holes and pulsars, which would also form gravity waves.” “The frequency we show has a broader spectrum, and its uniqueness would provide evidence of this s-fermion condensate,” he continues. “Such a condensate could have also inflated the primordial universe, while explaining the origin of tiny perturbations in the cosmic microwave background radiation.”However, Mazumdar admits, it may take some time to detect these waves and take the observations. “We’re hoping to detect these in four to five years at LIGO,” he says. “Scientists may find evidence of supersymmetry at the LHC, but we are hoping to find links to it in cosmology.”Article reference: Kusenko, Alexander and Anupam, Mazumdar “Gravitational waves from fragmentation of a primordial scalar condensate into Q-balls” arxiv.org/abs/0807.4554.Copyright 2007 PhysOrg.com.

Battery electrodes 40000 charge cycles look promising for grid storage

first_img One of the biggest problems researchers face is designing an inexpensive battery that can be recharged many times. Today’s lead-acid batteries typically last only a few hundred charge cycles, while lithium-ion batteries can last up to 1,000 charge cycles. Now in a new study, researchers led by Yi Cui, a materials science and engineering professor at Stanford University, have designed and demonstrated a battery cathode that lasts for 40,000 charge cycles while maintaining 83% of its charge-holding capacity. The results are published today in Nature Communications.The cathode consists of commonly available materials: crystalline nanoparticles made of Prussian Blue (an iron and cyanide compound) in which half of the iron is replaced with copper. The nanoparticles are then coated on a carbon substrate, which is immersed in an electrolyte solution of potassium nitrate.The researchers plan to design similar anodes to go along with the cathodes, which could then be used in a battery that Cui’s team is working on. That battery’s chemistry is similar to that of lithium-ion batteries but uses materials that are cheaper and more abundant, such as sodium and potassium ions and a water-based electrolyte, rather than organic solvent-based electrolytes.In addition to its high number of charge cycles, the cathode also has high efficiency of 99%. Although the cathode’s charge capacity is not as high as that of other batteries, its overall performance in a future battery could still make it advantageous in terms of overall cost.

Image credit: Colin Wessells, et al. (PhysOrg.com) — While researchers continue to improve solar and wind energy technologies, having a battery that can store the energy until it’s needed by the grid is another critical component for using renewable energy on a large scale. More information: Colin D. Wessells, et al. “Copper hexacyanoferrate battery electrodes with long cycle life and high power.” Nature Communications 2, Article number: 550, DOI:10.1038/ncomms1563Below is a press release issued by Stanford University:Nanoparticle electrode for batteries could make grid-scale power storage feasibleThe sun doesn’t always shine and the breeze doesn’t always blow and therein lie perhaps the biggest hurdles to making wind and solar power usable on a grand scale. If only there were an efficient, durable, high-power, rechargeable battery we could use to store large quantities of excess power generated on windy or sunny days until we needed it. And as long as we’re fantasizing, let’s imagine the battery is cheap to build, too.Now Stanford researchers have developed part of that dream battery, a new electrode that employs crystalline nanoparticles of a copper compound.In laboratory tests, the electrode survived 40,000 cycles of charging and discharging, after which it could still be charged to more than 80 percent of its original charge capacity. For comparison, the average lithium ion battery can handle about 400 charge/discharge cycles before it deteriorates too much to be of practical use.”At a rate of several cycles per day, this electrode would have a good 30 years of useful life on the electrical grid,” said Colin Wessells, a graduate student in materials science and engineering who is the lead author of a paper describing the research, published this week in Nature Communications.”That is a breakthrough performance – a battery that will keep running for tens of thousands of cycles and never fail,” said Yi Cui, an associate professor of materials science and engineering, who is Wessell’s adviser and a coauthor of the paper.The electrode’s durability derives from the atomic structure of the crystalline copper hexacyanoferrate used to make it. The crystals have an open framework that allows ions – electrically charged particles whose movements en masse either charge or discharge a battery – to easily go in and out without damaging the electrode. Most batteries fail because of accumulated damage to an electrode’s crystal structure.Because the ions can move so freely, the electrode’s cycle of charging and discharging is extremely fast, which is important because the power you get out of a battery is proportional to how fast you can discharge the electrode.To maximize the benefit of the open structure, the researchers needed to use the right size ions. Too big and the ions would tend to get stuck and could damage the crystal structure when they moved in and out of the electrode. Too small and they might end up sticking to one side of the open spaces between atoms, instead of easily passing through. The right-sized ion turned out to be hydrated potassium, a much better fit compared with other hydrated ions such as sodium and lithium.”It fits perfectly – really, really nicely,” said Cui. “Potassium will just zoom in and zoom out, so you can have an extremely high-power battery.”The speed of the electrode is further enhanced because the particles of electrode material that Wessell synthesized are tiny even by nanoparticle standards – a mere 100 atoms across.Those modest dimensions mean the ions don’t have to travel very far into the electrode to react with active sites in a particle to charge the electrode to its maximum capacity, or to get back out during discharge.A lot of recent research on batteries, including other work done by Cui’s research group, has focused on lithium ion batteries, which have a high energy density – meaning they hold a lot of charge for their size. That makes them great for portable electronics such as laptop computers.But energy density really doesn’t matter as much when you’re talking about storage on the power grid. You could have a battery as big as a house since it doesn’t need to be portable. Cost is a greater concern.Some of the components in lithium ion batteries are expensive and no one knows for certain that making the batteries on a scale for use in the power grid will ever be economical.”We decided we needed to develop a ‘new chemistry’ if we were going to make low-cost batteries and battery electrodes for the power grid,” Wessells said.The researchers chose to use a water-based electrolyte, which Wessells described as “basically free compared to the cost of an organic electrolyte” such as is used in lithium ion batteries. They made the battery electric materials from readily available precursors such as iron, copper, carbon and nitrogen – all of which are extremely inexpensive compared with lithium.The sole significant limitation to the new electrode is that its chemical properties cause it to be usable only as a high voltage electrode. But every battery needs two electrodes – a high voltage cathode and a low voltage anode – in order to create the voltage difference that produces electricity. The researchers need to find another material to use for the anode before they can build an actual battery.But Cui said they have already been investigating various materials for an anode and have some promising candidates.Even though they haven’t constructed a full battery yet, the performance of the new electrode is so superior to any other existing battery electrode that Robert Huggins, an emeritus professor of materials science and engineering who worked on the project, said the electrode “leads to a promising electrochemical solution to the extremely important problem of the large number of sharp drop-offs in the output of wind and solar systems” that result from events as simple and commonplace as a cloud passing over a solar farm.Cui and Wessells noted that other electrode materials have been developed that show tremendous promise in laboratory testing but would be difficult to produce commercially. That should not be a problem with their electrode.Wessells has been able to readily synthesize the electrode material in gram quantities in the lab. He said the process should easily be scaled up to commercial levels of production.”We put chemicals in a flask and you get this electrode material. You can do that on any scale,” he said.”There are no technical challenges to producing this on a big-enough scale to actually build a real battery.”Huggins is a coauthor of the Nature Communications paper.

Kraft uses Intel technology in vending machine to target customers by age

first_img(PhysOrg.com) — In a clever mix of technology and marketing, Kraft Foods has teamed up with Intel to create a vending machine, called the iSample, that can dispense free pudding samples to adults only; it’s intended target audience for its new product. The result is a machine currently in place at the Shedd Aquarium in Chicago. Patrons who approach the machine are scanned, and if deemed old enough, are urged to use their smart phone to type in or swipe a code that then allows the assumed grown-up to pick a flavor, which is then dropped down for them to grab and eat. All for free. If a kid tries to do the same, they are denied a free sample and asked to step aside so that a deserving adult can get a treat. Taiwan develops face-recognising vending machine The partnership between Kraft and Intel has apparently been ongoing for a couple of years as Kraft seeks new ways to grab the attention of customers and Intel works out real world ways to differentiate people from one another. As with most such ventures, the first such product, a similar scanning machine that could suggest an entire meal for someone based on gender, size and age, was deemed too ungainly. The new machine currently being used by passing adults at the aquarium is apparently just the right size and in addition to its technical abilities also employs a bit of humor, brushing children aside as if they were little more than pests.The new vending machine also appears to be a glimpse of things to come, as other companies are most assuredly working on similar technology, all aimed at selling more products to a cooperative public. Thus, in addition to television, radio, animated billboards and Internet advertising, we will all likely soon be subjected to various machines studying our bodies and faces to discover clues about our gender, age, race, health and perhaps level of wealth based on our clothing, so that those that wish to sell us things can be more discriminating in their advertising. All thanks to both investments in technology and the willingness of the public to give up some bit of their privacy in exchange for the reward of a simple sweet treat.

New study finds sea level rose 24 mmyear between 2005 and 2011

first_img Climate change will raise the sea level in the Gulf of Finland (Phys.org) —A new study conducted by researchers at the University of Texas’ Center for Space Research, indicates that sea level rise between 2005 and 2011 was due primarily to glacial and polar ice shelf melting. In their paper published in Nature Geoscience, the team describes how they studied data from satellites and ocean surface sensors to measure changes in ocean mass and density which allowed them to calculate an average global sea level rise of nearly 2.4mm/year. © 2013 Phys.org Explore further Global mean sea level (GMSL) change. a, GMSL change observed by the TOPEX/Poseidon and Jason-1/2 satellite altimeters during the period 1993–2012. b, The same as in a, but for the most recent 7-year period (January 2005–December 2011). Credit: (c) NPG, Nature Geoscience (2013) doi:10.1038/ngeo1829 More information: Contribution of ice sheet and mountain glacier melt to recent sea level rise, Nature Geoscience (2013) doi:10.1038/ngeo1829AbstractChanges in global mean sea level primarily reflect the sum of three contributions: water mass changes in the oceans, water density changes, and variations in the volume of the ocean basins. Satellite altimetry data1, 2, 3, 4 suggest that sea level rose by about 2.39±0.48 mm yr−1 between 2005 and 2011. However, previous estimates5, 6, 7, 8, 9 of sea level rise from density and ocean mass changes were lower than the altimeter data indicate. Here we show that the gap in the sea level budget disappears when we combine gravity data from the GRACE (Gravity Recovery and Climate Experiment) satellite mission and temperature and salinity observations from the Argo programme collected between 2005 and 2011. The Argo data indicate a density-driven sea level rise of 0.60±0.27 mm yr−1 throughout this period. To estimate ocean mass change from the gravity data, we developed a forward modelling technique that reduces the bleeding of terrestrial signals into the ocean data. Our reassessment suggests an ocean mass contribution of 1.80±0.47 mm yr−1, for a total sea level rise of 2.40±0.54 mm yr−1, in agreement with the altimeter-based estimates. On the basis of the GRACE data, we conclude that most of the change in ocean mass is caused by the melting of polar ice sheets and mountain glaciers. This contribution of ice melt is larger than previous estimates10, but agrees with reports11, 12, 13 of accelerated ice melt in recent years.center_img The researchers note that sea level changes come about in three main ways: changes in the mass of the water in the ocean, its density, and changes in the volume of ocean basins. To measure all of these over the period 2005 to 2011, the team studied data from the Gravity Recovery and Climate Experiment (GRACE) and from the Argo project (a global array of 3,500 profiling floats that record ocean temperatures and salinity on an ongoing basis.)Gravity data from GRACE allows researchers to measure the mass of the world’s oceans (divided into six regions) and thus the changes that occur over time. The data showed, the researchers report, a global increase in ocean mass that led to an average ocean level rise of 1.8mm/year during the years studied. They suggest the increase in mass was due to melting of the polar ice sheets and glaciers atop mountains around the globe.In studying data from Argo, the researchers found a reduction in the average density of the world’s oceans led to a rise in sea levels of approximately 0.6mm/year. The researchers did not delve into the nature of the decrease in sea water density, but the presumption is that it’s due to an increase in seawater temperature.To calculate the total average sea level rise over the years studied, the researchers added the rise due to an increase in ocean mass and the rise due to a reduction in average density—this gave them an average global sea level rise of 2.39mm/year. The researchers note their numbers reflect more rise than other studies have found but agree with those that have claimed sea levels are rising at an accelerated rate in more recent years. They also conclude that most of the change in global sea levels is due to melting of polar ice sheets and mountain glaciers.

The puffiest superNeptune has a cloudfree atmosphere new study finds

first_img Three new gas giant exoplanets discovered by SuperWASP-South (Phys.org)—Astronomers have recently conducted spectroscopic observations of the exoplanet WASP-127b – the puffiest “super-Neptune” known to date. The new study, presented in a paper published May 25 on arXiv.org, reveals that this alien world has an atmosphere, which is either completely or partially cloud-free. Example stellar spectra of WASP-127 (red) and the reference star (blue) obtained with the Grism #4 of NOT/ALFOSC on the night of February 23, 2017. The color-shaded areas indicate the divided passbands that are used to create the spectroscopic light curves. Note how the oxygen-A band region is excluded. Credit: Pallé et al., 2017. WASP-127b was classified as a so-called “super-Neptune” as with a mass of about 0.18 Jupiter masses, it is several times more massive than the solar system’s outermost planet. Due to its relatively large radius of 1.37 Jupiter radii, this exoworld is the puffiest, lowest density “super-Neptune” planet discovered to date.It takes about 4.2 days for WASP-127b to complete one full orbit around a bright G5 star located approximately 332 light years away from the Earth. The star’s brightness and its relative proximity, combined with the planet’s short orbital period, make WASP-127b an excellent target for atmospheric follow-up studies.That is why a team of astronomers led by Enric Pallé of the University of La Laguna, Santa Cruz de Tenerife, Spain, has conducted spectroscopic observations of WASP-127b utilizing the Andalucia Faint Object Spectrograph and Camera (ALFOSC). This spectrograph, mounted at the 2.5 m Nordic Optical Telescope (NOT) at Roque de los Muchachos Observatory, was used by Pallé’s team in February 2017 to observe a low-resolution, long-slit spectroscopic time series during a planetary transit and to obtain the first transmission spectrum for WASP-127b.Such observations are crucial in order to reveal insights about the atmosphere of this planet that could explain why WASP-127b is so inflated. Studying the planet’s atmospheric composition could offer clues on the nature of its intriguing inflation and its evolutionary history.ALFOSC observations allowed the researchers to find that the transmission spectrum of WASP-127b has strong spectral features. In particular, the spectrum shows the presence of a strong Rayleigh-like slope at blue wavelengths and a hint of sodium (Na) absorption.”At the bluer wavelengths, the spectrum shows a decreasing slope with λ, which seems to indicate the presence of Rayleigh scattering. A hint of Na absorption is seen (although statistically insignificant), with the band centered on the Na doublet presenting a larger planet to star radius ratio value than the surrounding bands,” the astronomers wrote in the paper.According to the researchers, these results suggest that WASP-127b seems to have a cloud-free atmosphere. However, more detailed observations are needed to definitively confirm this finding. The team proposes follow-up studies of this planet with ground-based telescopes and space observatories, including the powerful James Webb Space Telescope (JWST), which is planned for launch in October 2018. Further observations could confirm the team’s findings and extend them into the infrared regime, providing crucial information about the evolution of such inflated, low-density alien worlds.”Finding the physical mechanism(s) responsible for this inflation will help us understand how this type of planets evolve and how their fate is tied to that of their host star,” the authors concluded. © 2017 Phys.org Citation: The puffiest ‘super-Neptune’ has a cloud-free atmosphere, new study finds (2017, June 6) retrieved 18 August 2019 from https://phys.org/news/2017-06-puffiest-super-neptune-cloud-free-atmosphere.html More information: A feature-rich transmission spectrum for WASP-127b, arXiv:1705.09230 [astro-ph.EP] arxiv.org/abs/1705.09230AbstractWASP-127b is one of the lowest density planets discovered to date. With a sub-Saturn mass (Mp=0.18±0.02MJ) and super-Jupiter radius (Rp=1.37±0.04RJ), it orbits a bright G5 star, which is about to leave the main-sequence. We aim to explore WASP-127b’s atmosphere in order to retrieve its main atmospheric components, and to find hints for its intriguing inflation and evolutionary history. We used the ALFOSC spectrograph at the NOT telescope to observe a low resolution (R∼330, seeing limited) long-slit spectroscopic time series during a planetary transit, and present here the first transmission spectrum for WASP-127b. We find the presence of a strong Rayleigh slope at blue wavelengths and a hint of Na absorption, although the quality of the data does not allow us to claim a detection. At redder wavelengths the absorption features of TiO and VO are the best explanation to fit the data. Although higher signal-to-noise ratio observations are needed to conclusively confirm the absorption features, WASP-127b seems to posses a cloud-free atmosphere and is one of the best targets to perform further characterization studies in the near future.

Hakim said he would take up the matter with the state Public Vehicles department, to ensure that the delay in issuing driving licences is reduced.

The Mysterious Bison Herd Roaming on an Island off the California Coast

first_imgAlmost a century ago, a small herd of bison was supposedly transported to the island of Catalina, 22 miles off the coast of Los Angeles, to be in the background of a 1924 silent film being shot called The Vanishing American. But after the film was finished, no one rounded up the bison to transport them off the island. Their continued existence on Catalina has led to some real twists and turns. Catalina Island, claimed by the Spanish Empire before being relinquished to the U.S., possesses an intriguing history of smuggling and gold mining before it transformed itself in the 20th century as a place for relaxing. Twenty-two miles long and eight miles wide, it has trails to hike, oceanfront shops to scour, and snorkeling trips to book.Catalina IslandAnd then there’s the bison, a species that came close to extinction in the 19th century. “Catalina Island’s largest resident land mammal, brought over for a movie shoot and left to its own devices, the bison herd can be found roaming the interior of the island, where they are regularly spotted by hikers and other explorers,” said Catalina Tours.AdChoices广告inRead invented by TeadsWhile the film shoot story is accepted island history, there are some who are skeptical, pointing out that there are actually no bison visible in The Vanishing American. Yet it cannot be questioned that somehow the bison found a way there, and it’s an awful long boat ride from the mainland.A view of Avalon on Catalina Island. Photo by Frank Horst cc-by-sa-2.0Without natural predators and living in a mild climate, over the years the herd grew to at least 600–which was too many bison for the island to handle. Hundreds of them were taken off Catalina Island to live on Native American reservations, where their numbers had tragically dwindled after numbering in the millions for millennium.Experts say life post-Catalina is actually best for the bison. “They’re very challenged healthwise when they’re on this island, because they don’t have the adequate nutrition during the right time of year,” said Julie King, director of conservation and wildlife management at the Catalina Island Conservancy, in an interview with VOA. “So our bison are in fact a little smaller than the mainland, and it’s not a genetic difference. It’s due to not having the right nutrition at the right time.”Catalina Island interior. Photo by D Ramey Logan CC BY-SA 4.0Currently the Catalina bison number around 150. An argument exists that all the bison should be removed. “Ideally, as a wildlife biologist, I would say one is too many on this island,” says King. “They did not evolve on an island. Our largest native herbivore is a squirrel…not an 1,800-pound herbivore.”Bison on Catalina Island. Photo by tinyfroglet CC by 2.0The latest solution, since the bison are considered part of Catalina’s “cultural fabric,” is to keep the herd small through the use of birth control. Catalina Conservancy says, “To counter a growing herd size, the Conservancy initiated a contraception program in 2009 as a cost effective and humane approach to maintaining the bison population at sustainable levels. This program has been extremely successful and no additional bison calves have been born since 2013. Contraception halted temporarily and the Conservancy hopes to see bison calves on the Island again soon!”Related Video:While all sorts of jeep and hiking tours have taken interested visitors to observe the island’s largest mammals, they are by no means tame, and that was underscored in 2017.“A man who was camping at Little Harbor Campground on Catalina Island was injured after being gored by a bison the afternoon of Saturday, Feb. 17, police said,” according to a story in the Orange County Register. “The incident occurred at about 5:15 p.m. when the man was sitting on a log and a bison was grazing nearby, said Los Angeles County Sheriff’s Department Sgt. Ray Ward.”Related Article: 36,000-year-old Meat of a Mummified Bison was used for a StewThe sergeant told the newspaper, “When the man saw that the (animal) was getting closer to him, he got up and tried to move away. That’s when (it) charged him and gored him in his left arm.”Los Angeles Fire Department officials treated the man at the scene and he was airlifted to Harbor-UCLA Medical Center. “It’s very rare for them to attack,” Ward said. “People forget sometimes that they are wild because they appear domesticated.”Nancy Bilyeau, a former staff editor at Entertainment Weekly, Rolling Stone, and InStyle, has written a trilogy of historical thrillers for Touchstone Books.

Kevin Durant leaves OKC to play with the MVP

first_imgDraymond Green’s groin shot to Steven Adams in the Western Finals is now the second most infamous low blow in Oklahoma City Thunder history. Kevin Durant delivered the first today, when he declared his independence from the Thunder on the Fourth of July. He announced his decision to sign with the Golden State Warriors on the Players Tribune:“The primary mandate I had for myself in making this decision was to have it based on the potential for my growth as a player — as that has always steered me in the right direction. But I am also at a point in my life where it is of equal importance to find an opportunity that encourages my evolution as a man: moving out of my comfort zone to a new city and community which offers the greatest potential for my contribution and personal growth. With this in mind, I have decided that I am going to join the Golden State Warriors.”NBA Insider Marc Stein reported that the deal is for 2 years at $54 million.Kevin Durant will sign a two-year deal with the Warriors at $54.3 million, league sources say, with a Player Option for Year 2— Marc Stein (@ESPNSteinLine) July 4, 2016 Advertisement The 7-time NBA All Star, and his 28 points per game, will join Steph Curry, Klay Thompson, and Draymond Green on a Golden State squad coming off a record setting 73 win regular season and NBA Finals appearance. On paper it’s hard to say the lineup is anything other than nightmare inducing. Nick Wright, who was in for Colin, described the talent on the Warriors’ roster as historic.“This is the greatest collection of talent in modern NBA History.”It’s an embarrassment of riches for the Warriors, who now must figure out how to fit Durant into their offensive juggernaut as seamlessly as possible. Nick said haters who predict the Warriors will struggle like the earliest version of the LeBron Heat shouldn’t be so confident.“The Heat had to build an entirely  new system, the Warriors have a system. They’re just replacing Harrison Barnes with the second best, or the third best player in basketball.”Not surprisingly, Durant is already catching the third degree on social media for abandoning the Thunder, and for leaving to sign with the team that just bounced him in the Western Conference Finals.In the end, Durant chose the path with least resistance to his first championship trophy. Detractors may call him a ring chaser, but Vegas already has the Warriors listed as heavy favorite to win the NBA Championship when next season tips off.Updated 2016-17 NBA Championship odds via @LVSuperBookWarriors 4/5 Cavaliers 3/1 Spurs 8/1 Clippers 20/1 Celtics 20/1 Thunder 30/1— Covers (@Covers) July 4, 2016last_img read more

The Spurs dynasty is done

first_imgThe Spurs’ dynasty is doneThe Spurs were completely dismantled by the Rockets, 126-99, in Game 1 of their second round series, and Colin thinks San Antonio’s days as a title contender are done.Last night, they looked old, slow, and overmatched against the up-tempo Rockets. Even at their best, they were never a good watch. Now they’re boring and don’t have a roster that has evolved with the NBA’s three-ball heavy style of play.Besides Kawhi Leonard, they have a core roster of big name 30-somethings on the downside of their careers.He isn’t saying the Spurs are a poorly run organization, far from it. But, winning games and competing for titles are two different things. The Spurs, in their current form, won’t be winning anymore titles.“It’s over. They don’t want to admit it, but the big dynasty is over.” Guests:Doug Gottlieb – FS1 basketball analyst and hot of The Doug Gottlieb Show is in-studio talking the Rockets beat down of the Spurs; and what he would do with the Clippers; if Blake Griffin should be a part of the future.Ryan Leaf – Former #2 overall NFL Draft pick is in-studio to discuss transitioning from college to the NFL on and off the field; why Trubisky is being set up to fail; what advice he gave draft prospects; and what he sees now, when he watches his famous locker room tirade.Cris Carter –  FS1 Host and NFL Hall of Famer is in-studio to discuss the Bears drafting Trubisky and not telling Glennon; how he handled the same situation when the Vikings drafted Randy Moss; Nick Saban deserves more than $8 million per yearToday, it was reported that Nick Saban’s annually salary is $8 million per year. Predictably, the pearl clutching outrage at the idea of paying a college coach that much money has already begun. Colin doesn’t think it’s enough.College football coaches are like NFL quarterbacks. You can’t win titles, today, without them. Colin pointed out that if a university had the opportunity to buy some type of “device” that cost $8 million, but would guarantee a championship level program and also produce avalanches of revenue, they would jump at the chance.Oregon spent a zillion dollars on new facilities, but they’re irrelevant since Chip Kelly left.There is a device. It’s called a Nick Saban or a Jim Harbaugh. Schools should pay whatever they need to in order to get one.“The college football coach is the NFL quarterback.”last_img read more
