Existence of Universe Is Highly Improbable

first_imgTheologians might rightly celebrate a recognition by cosmologists that the universe is so finely-tuned, it shouldn’t exist.“Sir, I exist!” said a man to the Universe.  “However,” replied the Universe, “the fact has not created in me a sense of obligation.”  That joke by Stephen Crane points out that human existence is not a necessary consequence of Matter, if that is all the universe is.  But what if the Universe began the conversation?  “I exist!” said the Universe to Nothing and No One.  Those two would not only have no sense of obligation, they would be blind, deaf, and dumb to the statement.  Only God could celebrate the existence of a material universe, and He is under no obligation to create one.In that light, look at a news article by Tia Ghose on Live Science: “Universe Shouldn’t Be Here, According to Higgs Physics.”  The Higgs boson discovery was the big event of 2012.  It produces the Higgs Field in the Standard Model that gives mass to particles.  Ghose translates the complexities of the theory into pithy lay language:Modeling of conditions soon after the Big Bang suggests the universe should have collapsed just microseconds after its explosive birth, the new study suggests.“During the early universe, we expected cosmic inflation — this is a rapid expansion of the universe right after the Big Bang,” said study co-author Robert Hogan, a doctoral candidate in physics at King’s College in London. “This expansion causes lots of stuff to shake around, and if we shake it too much, we could go into this new energy space, which could cause the universe to collapse.”In short, the expansion had to be finely-tuned for the Universe’s existence—and ours.  Although the alleged confirmation of inflation is being debated (see 6/24/14), the properties of the Higgs Field are tenuous in any expansion.  Cosmologists at King’s College London looked into their models:What they found was bad news for, well, everything. The newborn universe should have experienced an intense jittering in the energy field, known as quantum fluctuation. Those jitters, in turn, could have disrupted the Higgs field, in essence rolling the entire system into a much lower energy state that would make the collapse of the universe inevitable.Ghose states that “this isn’t the first time that physicists have said the Higgs boson spells doom for the universe.” Yet the Universe continues to affirm, “Sir, I exist!”  It points to dozens of parameters (the fine structure constant, the ratio of proton to electron mass, the charge on the electron, etc.) that are finely-tuned for its existence, suggesting design.  Now it adds the Higgs field to its list:The mass of the Higgs boson, about 126 times that of the proton, turns out to be “right on the edge,” in terms of the universe’s stability, [Sean] Carroll [Caltech] said. A little bit lighter, and the Higgs field would be much more easily perturbed; a little heavier, and the current Higgs field would be incredibly stable.A press release from the Royal Astronomical Society agrees that the finely-tuned Higgs field could not survive inflation:Measurements of the Higgs boson have allowed particle physicists to show that our universe sits in a valley of the ‘Higgs field’, which describes the way that other particles have mass. However, there is a different valley which is much deeper, but our universe is preventing [sic] from falling into it by a large energy barrier.The problem is that the BICEP2 results predict that the universe would have received large ‘kicks’ during the cosmic inflation phase, pushing it into the other valley of the Higgs field within a fraction of a second. If that had happened, the universe would have quickly collapsed in a Big Crunch.At this point, the Universe might retort, “Sir, God exists!”   But cosmologists would rather invent new physics than go there:“This is an unacceptable prediction of the theory because if this had happened we wouldn’t be around to discuss it” said [Robert] Hogan [King’s College London], who is a PhD student at KCL and led the study.Perhaps the BICEP2 results contain an error. If not, there must be some other — as yet unknown — process which prevented the universe from collapsing.“If BICEP2 is shown to be correct, it tells us that there has to be interesting new particle physics beyond the standard model” Hogan said.This leaves secular cosmologists needing inflation to solve the horizon problem, but cursing inflation for destroying the universe.Perhaps they should take a lesson from the brilliant but eccentric mathematician, Kurt Gödel, whose life and major contributions were described on PhysOrg recently.  Best known for his Incompleteness Theorem, Gödel sounded the death knell for positivism: the early 20th century arrogant belief that mathematicians were on the verge of describing everything.   Gödel proved that mathematics cannot explain itself within its own axioms.  Others have extended this Incompleteness Theorem to other areas of philosophy (e.g., Adami, 8/13/07; Wolpert, 10/16/08).  It implies that to explain the universe, philosophers will have to look for necessary and sufficient causes outside the universe.Update 6/30/14: The BBC News reported on the Higgs theory, the history of the find, anticipations of more discoveries at CERN’s newly-updated LHC next year, and the finely-balanced nature of the Higgs boson’s mass:To use an analogy, imagine the Higgs boson is an object resting at the bottom of a curved slope. If that resting place really is the lowest point on the slope, then the vacuum of space is completely stable – in other words, the Higgs is in the lowest energy state and can go no further.  However, if at some point further along this slope, there’s another dip, the potential exists for the Universe to “topple” into this lower energy state, or minimum. And if that happens, the Universe would be doomed.The article goes on to mention that the Standard Model still leaves important factors in the universe unexplained.  Peter Higgs makes a cameo appearance in the article.People know instinctively the world is designed.  They have to be trained not to know it.  Scientists, especially, undergo rigorous training to lose their common sense.  Oh, they have common sense within their world view, but when their restricted common sense runs into roadblocks inside their secular box, they fret and fume and refuse to consider the obvious implication.  They love darkness rather than light.  That’s why they chase phantoms like dark matter, dark energy, and dark “new physics” that nobody has ever observed or even knows how to observe.  Anything but Intelligent Design!Their reactions undercut their logic.  By using argumentation, rationality and emotion, they prove they already are Supernaturalists, because such things do not derive from particles and forces.  Indeed, particles and forces fall into the Incompleteness Theorem; they can only be understood with reference to reality outside themselves—the conceptual world of mind and logic.  That reality, subsequently, can only be understood with reference to a greater Reality outside it—a personal, rational, eternal God: the First Cause from which everything derives.Theologians and creationists have pointed to the fine-tuning of the universe, the Anthropic Principle and such things for decades.  The only sufficient condition for the Universe’s ability to say “I exist!” is the foundation in Genesis 1:1, “In the beginning, God created the heavens and the earth.”   We’ve seen in recent years the atheists rushing to embrace a multiverse instead of creation (5/17/14), despite the infinite regress trap it presents to them.  What we see with the current hand-wringing over the finely-tuned Higgs field is just more of the anti-rational reaction Paul described so well in Romans 1:18-24.

SA to host African Gymnastics Champs

first_img16 January 2014 South Africa’s leading gymnasts will take on the continent’s best when the University of Pretoria hosts the 12th African Gymnastics Championships from 25 March to 4 April. Both men and women will compete in the artistic competition, while the women will also contest the rhythmic disciplines. Much will be expected of Cameron MacKenzie and Kirsten Beckett, who will be at the forefront of the South African team’s challenge.‘A welcome shot in the arm’ After spending a decade abroad, MacKenzie provided South African gymnastics with a welcome shot in the arm when he returned from the United Kingdom in October, having represented Great Britain at junior and senior level. He was a member of the Huntingdon Club, which also produced Olympic medal winners Louis Smith, Daniel Keatings and Sam OldhamAchievements MacKenzie’s list of achievements includes representing Britain at the World School Games in Qatar in 2009 and being part of the Great Britain National Gymnastics squad that won team gold at the Junior European Championships in 2010. That same year he won gold in the Junior Men’s All-Around at the Bumbo Cup in South Africa. More recently, in 2013, MacKenzie placed sixth in the Senior Men’s All-Around at the British Championships in Liverpool.Commonwealth Games places In the South African artistic trials last year, he confirmed his pedigree by finishing first in the all-round competition. After also excelling in the apparatus finals he secured a place in the South African team for the 2014 Commonwealth Games, along with Tiaan Olivier, Kirsten Beckett and Claude Cummings. MacKenzie’s UK coach Paul Hall has been signed up to help with a training plan for the both the South African junior and senior men’s artistic gymnastics teams. Kirsten Beckett Beckett, aged 17, first competed outside of Africa in 2008. Last year, in the International Gymnastics Magazine, John Crumlish wrote: “Beckett’s achievements in 2012 continue the momentum generated by South African teammate [and 2010 Commonwealth Games silver medal winner in the vault] Jennifer Khwela earlier in the Olympic cycle”. In 2013, Beckett was South Africa’s top performer in her first visit to the World Championships. She is ranked ninth on the floor in the latest International Gymnastics Federation world rankings, up from 24th in 2012. She is also ranked 12th on the vault, and 49th on the uneven bars.Revival Gymnastics South Africa is aiming to use the African Championships to help spearhead a revival of the country’s international fortunes, which peaked in 1998 at the Commonwealth Games when Simon Hutcheon won gold in the men’s vault, Christian Brezeanu captured silver in the vault and on the floor, and Athol Myhill won bronze on the rings.Support To show your support for Gymnastics South Africa, visit the 12th African Gymnastics Championships pages on Facebook and Twitter.

In-season scouting and data collection with APPs

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By John Fulton, Trey Colley, and Jenna LeeCollecting in-season data including scouting intel and imagery can be useful on the farm. For those conducting on-farm studies, collecting data beyond yield can provide valuable context when evaluating yield results post-harvest. There are several mobile applications (APPs) available today that can assist with scouting and collecting data. The value with many of these APPs is having:Information at your fingertipsEfficient collection and storage of data, images, notes, etc.The ability to share collected information with others quicklyAccess to collected information later in the season, post-harvest or next yearThe capability to geo-tag while collecting data and imagesData and information available when evaluating post-harvest results.One app that allows you to have all of benefits in one is the Ohio State PLOTS App. This is an on-farm research app provided by The Ohio State University free of charge. PLOTS allows the user to set-up replicated field studies, capture geo-tagged notes/images during the growing season, and performs statistical analyses on collected crop data. PLOTS is a safe, secure, and is backed up to cloud storage. We also suggest having a good weather APP that you can reference throughout the growing season.Many other apps allow for in-season data management and recording, here are a few that we currently use: Planting Population Calculator by AgPhD — planting population and stand countsOhio State PLOTS — generate plots and statistics for on-farm researchClimate Fieldview by the Climate Corporation — collect and store field dataSoil Test Pro — lab results, fertilizer recommendations and controller filesEncirca View — field location via satellite imagery and notes/photosAirScout — aerial imagery based scouting applicationTrimble AgMobile — record keeping, crop scouting, mapping, grid samplingWeather Underground — hyperlocal forecasts, interactive radar, severe weather alertsField Pest by AgPhD — identify pests by name or image.This list does not represent all APPs that can be used for in-season data collection.

Soybean and corn export outlook

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Todd Hubbs, University of Illinois Department of Agricultural and Consumer EconomicsThe escalating trade issues between the U.S. and many of our trading partners continue to affect the outlook in both corn and soybean markets. Drastic price declines since Memorial Day show the impact of trade uncertainty and yield potential. The prospect of large yields combined with trade issues set the baseline for determining export potential and price formation in both corn and soybean markets moving forward.The USDA soybean export projection for the current marketing year totals 2.085 billion bushels, up 20 million bushels from June’s estimate. Census Bureau export estimates through May place soybean exports at 1.762 billion bushels. Census Bureau export totals came in 42 million bushels larger than cumulative marketing year export inspections over the same period. As of July 12, cumulative export inspections for the current marketing year totaled 1.873 billion bushels. If the same difference in export pace continued through the current period, soybean exports would total 1.915 billion bushels as of July 12.For the remainder of the current marketing year, 24.2 million bushels of soybean exports are required each week to meet the USDA projection. During the last four weeks, export inspections of soybeans averaged 24.5 million bushels per week. Low soybean prices encouraged sales to destinations other than China over the last few weeks. As of July 5, total outstanding sales for the current marketing year totaled 263 million bushels, which is well above the estimated 170 million bushels required to meet the USDA projection. While China looks to cancel the 26 million bushels of outstanding sales it possesses, total outstanding sales still sit above the estimated total to meet USDA projection for this marketing year.Adjustments to 2018-19 marketing year trade numbers in the latest USDA forecasts present a bearish picture for soybean exports. A reduction of 250 million bushels, to 2.04 billion bushels, from last month’s soybean export forecast is not a surprise given the current trade environment. In conjunction with lower U.S. soybean export projections, the USDA reduced the Chinese soybean import forecast to 3.491 billion bushels. The 73 million bushel reduction from last marketing year is the first decrease in year over year imports by China since the 2003-04 marketing year. While Chinese imports appear set to decrease, the USDA projects substantial increases in South American production next marketing year. Argentine recovery from last season’s drought and expanded acreage in Brazil place soybean production forecasts in the region at 7.1 billion bushels, up 808 million bushels from the current marketing year. Barring a resolution to current trade issues, soybean exports next marketing year will struggle despite the low prices currently in place.The prospect of record corn yields and the uncertainty surrounding trade continue to place pressure on corn prices. At 2.4 billion bushels, the USDA estimate for corn exports during the current marketing year appears somewhat optimistic given cumulative exports to date and unshipped sales. Export estimates by the Census Bureau through May place corn exports for the marketing year at 1.656 billion bushels. Through July 12, cumulative export inspections totaled 1.907 billion bushels. Using the relationship between export inspections and Census Bureau totals, exports for corn currently sit at 2.01 billion bushels. For the remainder of the marketing year, export inspections need to average approximately 56 million bushels per week to meet the USDA projection. For the last four weeks of export inspection data, corn exports averaged 56.7 million bushels per week. Total outstanding sales for the current marketing year sit at 454 million bushels, which is above the 394 million bushels required to reach the USDA projection. While corn exports may fall short of the current estimate, the blistering export pace in the second half of this marketing year looks set to continue into the fall.Current USDA projections for corn exports during the 2018-19 marketing year total 2.225 billion bushels, up 125 million bushels from last month’s projections. World import projections during the upcoming marketing year provided by the USDA sit at 5.95 billion bushels, up 193 million bushels over the current marketing year estimates. A low price and poor corn crops in South America and the Black Sea region provide an outlook for continued strength in corn exports as we move into the next marketing year. Current export sales data give indications to support this idea. As of July 5, corn outstanding sales for the 2018-19 marketing year sit at 183 million bushels, a 41 percent increase in sales from the same time last year.Exports in both corn and soybeans built some strength over the last few weeks as lower prices spurred demand. Current estimates of export pace place both crops on track to meet or come near USDA projections for this marketing year. The size of the 2018 crop domestically and in key producing regions will provide a critical factor in determining U.S. export potential next marketing year. A resolution of trade issues with China and NAFTA partners would provide needed support. Current developments appear to make this a low probability event in the near term.last_img read more

Updates on Startup-Related Legislation: Startup Visa, Finance Reform Bill

first_imgTwo pieces of legislation of particular interest to the startup community continue to wind their way through Congress: Senator Lugar and Kerry’s Startup Visa Act and Senator Dodd’s Financial Reform bill. We’ve written about bothhere before.Restoring American Financial Stability Act The Restoring American Financial Stability Act passed the US Senate on May 20 and now heads to conference committee to reconcile the differences between the House and the Senate versions. The investor and startup community have long been concerned about the contents of Senator Dodd’s financial reform bill, as it would erect several barriers to funding by changing the requirements for investor and business registration. In the final Senate version, some of the parts most troubling to investors and startups were removed from the bill, including the provision that would require 120-day waiting period for state regulators to review any investment deal. The new income and net worth requirements for angel investors are still in place, but these will not increase with inflation. The SEC will review accredited investors every four years. An amendment to the bill was accepted, expressly aimed to protect angel investment. Liddy Karter, chairman of the AngelCapital Association (ACA) said in a press release, the amendment “ensures that entrepreneurs will more easily be able to raise angel capital and more accredited investors can continue making the angel investments they love to make.” Startup Visa Act Senator Kerry and Lugar’s Startup Visa Act is also in committee. Introduced in February, the Startup Visa Act will help foreign-born entrepreneurs secure visas. The proposed legislation will change the current requirements that now says investors from other countries must have $1 million in capital in order to get a visa to start a business in the US. The Startup Visa Act, supported by a number of investors, includingEric Ries, Dave McClure, Shervin Pishevar, Brad Feld, Paul Kedrosky, Manu Kumar, & Fred Wilson, proposed that non-US born entrepreneurs could get a visa as long as they had funding from a US investor. Although the bill is in committee, Dave McClure did have an impromptu meeting with Secretary of State Hilary Clinton, urging her support for the legislation. Her staff, reports McClure, will follow up.As research shows, young high-growth businesses generate a substantial number of new jobs, an argument that startups and investors will be sure to make as legislators debate the outcome of these two important bills.

Google Seeking Developers to Make Wave-Based Forum

first_imgThe idea has been batted around before, but now it looks like Google is ready to throw some effort in the direction of creating a Google Wave powered forum.According to a post on the Google Wave Developer Blog, the Google Wave team already open-sourced Forum Botty, a Google Wave extension that creates a forum-like experience inside Wave, and now it wants to “continue developing this code base into a powerful and generic extension for running forums in wave, and we’re hoping that other developers like you will join us in this project.”Google Wave is a real-time, collaborative environment that Google made available to the public at the end of May. Despite much hype and anti-hype (where detractors rush to call it dead), it looks like Wave is still very much alive and kicking and looking at some interesting new uses.The post on the developer blog is written by David Crane, an external Wave developer who is involved in the development of the Debatewise extension. With his work on Debatewise, Crane has already used Wave in holding mass discussions, so he already has some experience in the realm of creating a Wave-based forum. Crane writes that Wave is better than a standard forum right from the get-go:Google Wave offers a number of benefits over traditional forum software, with just its native functionality. However, by incorporating some of the tried-and-tested features from forums into a robot, we could turn Google Wave into the ultimate platform for forum-based discussion.A forum could be a killer app for Wave. It’s a tool that people already use in huge numbers for specific purposes, are used to keeping separate to their email, and will dip in and out of as required. Wave is similar enough for them to jump in quickly and different enough for them to get, and be hooked by, the benefits. A forum removes the need for people to find things to use Wave for and means they could use it even if none of their friends did. Wave could enhance and improve upon some of the most important features of a forum and through acclimatisation, will encourage them to use it for a world of other purposes.Crane says that there are three areas in need of developing: a way of organizing waves around subject matter, a method of encouraging participation with rewards and the development of “trust mechanisms so people can determine who to rely upon or ignore”.To this end, he says that they are looking for “Python, Java and Javascript developers, QA testers and anyone with an interest in forum software, community building and online discussion”. The resulting Wave-based forum will be licensed under the same open-source license used for Google Wave, meaning it will be open for others to implement and modify.
