Is a Multiverse Detectable?

first_imgThe idea of a multiverse (an ensemble of universes like our own visible one) has been criticized as unscientific because it would be unobservable, even in principle.  Now, however, some theoretical physicists are claiming that bubble universes beyond ours could be detected in the cosmic microwave background radiation – provided they collide with our universe.  Does this bring multiverse theory back into the realm of science? National Geographic News, posting an article on this idea, said, “The multiverse, if it exists, may have sprung out of a chaotic fluctuation of empty space.”  Chaotic motions from other bubble universes might “bruise” our universe and leave telltale patterns in the cosmic microwave background (CMB).  Matthew Johnson, a theoretical physicist at the Perimeter Institute, with colleagues, is working on an algorithm to find the patterns. But what to look for?  Sean Carroll, physicist at Caltech, warned that “People tend to recognize patterns whether or not they are there.”  Trouble is, nobody knows what the needle in the haystack would look like.  “Even with better data from Planck” (a new space telescope measuring the CMB in finer detail), “finding evidence of a universe-to-universe smashup is a game of chance, thanks to the nearly infinite possible outcomes.”  For this reason and the fact that any deviations in the CMB are likely to be extremely subtle, Carroll thinks the quest is “a long shot”.  But the implications would be so earth shattering, he is eager to see what Johnson and team find. They don’t know what they are looking for, they don’t know what they might expect to find, and they won’t be able to confirm it when they see it.  Imagine looking for a what-not in a pile of whatever, that might leave an infinite set of possible outcomes.  You could claim success and nobody could ever confirm or deny it.  NG unabashedly stated another piece of nonsense: “The multiverse, if it exists, may have sprung out of a chaotic fluctuation of empty space.”  The whatever, if it exists, might have spring out of a chaotic what-not.  Isn’t science wonderful. The elephant in the room that Carroll, Johnson, Hawking and all the other multiverse advocates are overlooking is the question of ultimate origins.  Even if, in their wildest dreams, in spite of overwhelming odds, they had some basis for claiming that some other bubble is pushing on our bubble, they would merely displace the question of ultimate origins to another location.  Let them start with what Francis Schaeffer called “nothing nothing” – no space, no time, no laws of nature, no fields, no categories.  From absolutely nothing, get them to derive not only a universe, but reasoning beings questioning its origin and destiny.  The folly of such a quest is self-evident. Exercise.  See if Ethan Siegel in “The Physics of Nothing, The Philosophy of Everything” on ScienceBlogs.com succeeded in building a universe out of nothing nothing.  (Hint: philosophy and laws of physics are something.)(Visited 47 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

You really need a cover crop this year

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Harold Watters, Ohio State University Extension agronomistSo I made a trip to Omaha and back in mid-July. I attended the Sustainable Agronomy conference there and drove to the conference. Part of my goal was to do a windshield tour to see what the crops really looked like. Generally, nothing looks as it should. Ohio and eastern Indiana are the worst in many ways, but the total loss of crops due to floods in western Iowa and into Missouri were the most tragic — many losing not just this year’s crop but also last year’s that was still in the bin when floods hit this spring.I drove out and back by two different routes to get a bigger picture of what’s there, on I-80 out and U.S. 36 back for the most part. I rated the crop on a 1-10 scale with 1 being just planted or mostly flooded out to a 10 being perfect — I think I only saw one 10. We made 110 observations doing a check on both sides of the road every 20 minutes. Dark cut off our observation at around Indianapolis on the way back.Rating of corn and soybean crops on a trip from central Ohio to Omaha and back. The scale is 1 to 10, with 1 being just planted to nearly flooded out and 10 being as nice as you would expect in mid-July.OhioIndianaIllinoisIowaMissouriAve corn2.54.97.16.87.0Ave soy3.03.73.35.64.6Unplanted25%30%3%13%39%It really isn’t pretty anywhere. This year you really need a cover cropTypically, I place a cover crop article here now as I think early August is a great time to plant our fall seeded cover crops. It’s after wheat harvest, and this year there are maybe 1.5 million acres of Ohio cropland unplanted — put a cover crop there too. Mark Sulc, our OSU Forage specialist, is great at finding the value of cover crops, I choose his advice over many of the so-called cover crop experts. He created a quick and dirty table to point out some choices for summer to late-summer seedings. In addition to the species to choose from he has timing, seeding rate, and expected yield — this can also indicate the amount of cover for soil erosion protection too. He adds Crude protein and NDF as well so you may see the nutritional value if haying or grazing.Annual Forage Agronomic Guidelines and Characteristics from R. Mark Sulc (sulc.2@osu.edu) on July 8. Yield and nutritive value vary greatly with maturity stage at harvest. If you want additional ideas for cover crops that you do not intend to feed, and there is much overlap, then see the Midwest Cover Crop Council’s website and cover crop calculator: http://mccc.msu.edu/covercroptool/covercroptool.php. Much of my experience is with oat, and winter pea. For peas from the planting date trials I conducted, peas like an August to mid-September planting. With August planting you will get a lot of fall growth, then it will usually winter kill. With a September planting it will most likely not give you much fall growth, but survive the winter and continue growth in the spring. Peas are great to plant into; and have given me the best seed bed I think I have ever had for no-till corn.last_img read more

Payal Tadvi’s death: Two more doctors held; all three accused remanded in police custody till May 31

first_imgAccording to sources, several teams from the Agripada as well as nearby police stations formed for the purpose talked simultaneously to the relatives of the accused over the course of the last two days to gain leads about their whereabouts. Dr. Mehare was arrested from Mumbai on Tuesday when she came to meet her lawyer in connection with their anticipatory bail application. Dr. Ahuja was picked up near the Andheri railway station by a team from the Agripada police station on Tuesday night and Dr. Khandelwal from Hinjewadi in Pune by a team from the Nagpada police station.The next challenge before the police was the rule that a woman accused cannot be arrested after sunset. “As soon as we picked up Dr. Ahuja and Dr. Khandelwal, we approached a magistrate late at night and got an order signed from him permitting us to arrest them after sunset. As per law, such an arrest can only made with a magistrate’s order,” Deputy Commissioner of Police (Zone III) Abhinash Kumar said.The two were then taken to the office of the Assistant Commissioner of Police Deepak Kundal, Agripada division, who is spearheading the probe and placed under arrest. All the three accused were subsequently produced in court on Wednesday morning and remanded in police custody till May 31.Investigating officers said the three accused had gone to Dr. Tadvi’s room the day she committed suicide, and this aspect needed to be probed further. “Dr. Tadvi’s mother has expressed suspicion that the trio might have found a suicide note blaming them for the extreme step and destroyed it. We will be interrogating the accused in connection with this,” the officer said.The police, however, are still looking for evidence to substantiate the claims of Dr. Tadvi’s family that she was harassed due to her caste. Sources said that statements of over 20 witnesses had been recorded so far, but no proof of casteist slurs has come to light.“On the other hand, Dr. Tadvi, in one of her messages to her mother, had said that the three accused do not even know her caste,” the officer said……………….Those in distress or having suicidal tendencies could seek help and counselling by calling any of the following numbers:BMC Mental Health Helpline: 022-24131212 (24×7)Vandrevala Foundation: 18602662345/18002333330 (24×7)I Call – 022-25521111 (8 a.m. to 10 p.m., Monday to Saturday)The Samaritans Mumbai: 8422984528/842984529/8422984530 (3 p.m. to 9 p.m., all days) Senior doctor held for Payal Tadvi’s death The two absconding doctors booked for allegedly abetting the suicide of Payal Tadvi, a second year resident doctor with the BYL Nair hospital, were arrested in the early hours of Wednesday by the Agripada police.Hema Ahuja, Bhakti Mehare and Ankita Khandelwal, all third-year resident doctors, were booked on May 23 this year, a day after Tadvi killed herself in her hostel room on the hospital’s premises.

Braxton Millers onfield growth prepares him for Fighting Illini

Then-freshman OSU quarterback Braxton Miller (5) is tackled during a game against Illinois Oct. 15, 2011. OSU won, 17-7.Credit: Lantern file photoJunior quarterback Braxton Miller was thrown to the wolves in his freshman season with the Ohio State football team.Miller was the starter at quarterback in each of the final 10 games of 2011, including the Buckeyes last game at Illinois’ Memorial Stadium, Oct. 15, 2011.In that game OSU pulled off a 17-7 victory, although Miller only completed a single pass.“I was thrown in there early. I don’t think I was ready at that time, but I did what I had to do,” Miller said after practice Wednesday. “It was kind of a big stage at that time, so I had to prepare and it was kind of tough and I didn’t expect to play as a freshman.”Now the No. 3 Buckeyes (9-0, 5-0), will return to Memorial Stadium Saturday, looking to extend the nation’s longest winning streak to 22 games.Coach Urban Meyer, who took over the Buckeyes following the 2011 season, said Miller has come a long way since that game.“I can assure you that (he’s) in a much different place than he was two years ago,” Meyer said Monday.It was a career-low in completions and passing yards for Miller, who has since developed into one of the top quarterbacks in the country. He was named a semifinalist for the Davey O’Brien award Nov. 4.Junior wide receiver Evan Spencer said the game in 2011 was a difficult situation because of Miller’s inexperience.“His freshman year, it was kind of a unique situation for all of us really and we were trying to win games (OSU finished the year 6-7), whatever it took to win a game,” Spencer said after practice Monday. “So now that he has really developed as a passer and he’s gotten better at reading what he has to do, we flow so much better.”Redshirt-senior left tackle Jack Mewhort said in hindsight, it’s hard to believe the Buckeyes only completed one pass during that game.“Looking back, that’s crazy to me just because our passing game has evolved so much now and so many different guys can score touchdowns for us now,” Mewhort said Monday. “One pass, that’s kind of unreal to think about, and Braxton and the skill guys have come so far.”In his freshman season, Miller averaged 96.6 yards passing yards per contest. This season, Miller has almost doubled his weekly output from two seasons ago, throwing for an average of 188 yards per game.Spencer said Miller’s development as a passer has helped the offense become more balanced this season.“It definitely changes the dynamic. We’re putting up 40-some points a game, so it’s working pretty well for us and his development,” Spencer said. “It’s coming along great … He’s playing really well right now and us as receivers, we’re executing pretty well for him.”Mewhort added that even compared to last year, Miller has become a better passer, helping the Buckeye running game in the process.“Last year, there were some games where teams played us real heavy in the box because we couldn’t do as much with our passing game, but this year, it’s a lot different. There’s not eight or nine guys in the box because this offseason Braxton, the wide receivers, the running backs and the skill guys got together and decided, ‘We’re going to be really good this year,’” Mewhort said. “I think they’ve done that so far, they’ve gotten better every game and that makes it easier on the (offensive line) and the running game, knowing that there are other threats.”In 2012, the Buckeyes beat Illinois, 52-22, with Miller throwing for 226 yards and two touchdowns on 12 completions.Meyer said having a quarterback and leader like redshirt-senior Kenny Guiton to look up to has been a boost for Miller this season – something he did not have the luxury of his first year on the job.“I think the way these two quarterbacks are now preparing, with all due respect to when Braxton was a freshman, he really didn’t have anyone to look up to to say, ‘This is the way to prepare for a college football game.’ And certainly last year, we were just still trying to teach Kenny because Kenny didn’t really know, because neither one of them really played,” Meyer said. “Now they’re both operating at a very high level, they’ve practiced very hard, they prepare very hard, much different than a year ago, so I think Kenny had a lot to do with it and it’s a direct result of the way he prepares, the way he practices.”His relationship with Guiton has been really important in his time at Ohio State, Miller said.“I look up to him as a big brother, I’ve talked to him ever since I was being recruited,” Miller said.Miller hopes to improve on his last trip to Champaign, Ill., Saturday at noon when the Buckeyes are scheduled to take on the Fighting Illini (3-6, 0-5). read more

Dino Zoff doesnt believe Juventus can win the CL

first_imgFor the legendary coach, the Italian club are now stronger than Real Madrid, but this doesn’t mean they can win the Champions League, yetWhen a football legend talks, you listen.That’s what fans in Italy are doing after 1982 World Cup winner and 2000 Euro Cup coach Dino Zoff spoke about Juventus and their title chances.“I don’t think Juventus have less quality than Real Madrid. In fact, quite the opposite, as I believe they are stronger on paper than the Spaniards,” he said to RMC Sport radio as reported by Football Italia.Mario Mandzukic, JuventusJuventus confirm Mario Mandzukic could leave this month Andrew Smyth – September 14, 2019 Sporting director Fabio Paratici confirmed reports that Mario Mandzukic could leave Juventus for a move to an unnamed Qatari team.“However, that doesn’t mean they will win the Champions League. There is more to it than that.”“It doesn’t matter who scores for Juve. I think Paulo Dybala can adapt and play like Isco to help feed Cristiano Ronaldo,” he added.“Gonzalo Higuain has gone to Milan and he is completely different to Karim Benzema. He prefers a central role, whereas Benzema likes to roam all along the front line.”“It’s too early to say if Inter will be the main challengers to Juve. They have the potential in the squad and an opening defeat can happen,” he commented.last_img read more

Samir Nasri Im a different man now

first_imgFrench midfielder Samir Nasri feels “blessed” to have been given a second chance following his move to West Ham and promises he’s a changed manThe 31-year-old was given an 18-month ban from football after breaching the World Anti-Doping Agency (WADA) rules in 2016.The suspension came shortly after his contract with Turkish side Antalyaspor was terminated with his last competitive outing being in August 2017 in a Super Lig match against Yeni Malatyaspor.But now Nasri has been given a rare second chance in a top Premier League club after convincing his former Manchester City boss Manuel Pellegrini of his fitness.Although the ex-France international admits he thought his career might come to an end at one stage.“I had some really tough moments when I was really down,” Nasri told West Ham TV on YouTube.“Mentally I’m really strong, but for maybe the first time in my life, I cried about my career because I thought it was over.Jose Mourinho is sold on Lampard succeeding at Chelsea Tomás Pavel Ibarra Meda – September 14, 2019 Jose Mourinho wanted to give his two cents on Frank Lampard’s odds as the new Chelsea FC manager, he thinks he will succeed.There really…“I’m 31 years old now and I’m more mature. If it was five years ago maybe I would have some problem with it or talk too much about it.“When you’ve been out for a year and you think it’s over, you think completely differently after that.“I was just looking on TV and I wasn’t able to train, and in the meantime, I had a son. A lot of things have changed in my life, and for the best. I’m really happy about it. I’m just blessed.“I’m lucky to have a second chance. Not everyone in life has a second chance and I do. I know I will give 100 per cent.”Nasri could make his West Ham debut on Wednesday at home to Brighton.last_img read more
