[Guest article] According to the July issue of Astronomy magazine, the Universe is comprised mostly of fudge – or at least fudge factors, anyway. The article by James Trefil from George Mason University describes the current thinking among astrophysicists as to the eventual fate of the universe. Since the Big Bang, there has been an expansion:On one hand, the expansion could reverse, in which case, all the matter in the universe would come together again – the Big Crunch… On the other hand, the expansion could go on forever, leading to a bleak, cold, and empty future – the Big Chill.There is a happy medium called the “flat universe,” where we don’t Crunch or Chill, but coast happily outward forever. There is a quantity of matter in the universe necessary for the happy coasting. It is called the critical density, and theorists believe that the universe must be at that value in order to observe what we see today. There is a problem, however: “If you count up all the stuff astronomers see – stars, dust clouds, and other kinds of ordinary, or baryonic, matter – it totals about 4 percent of the critical density.” This is way too little to get to the critical density. In addition, astronomers note that galaxies rotate strangely. The arms of the galaxies, being further away, should, over time, separate from the inner regions of the galaxy. Enter fudge factor #1, “dark matter:”The only way for this to happen is for the visible galaxy to be surrounded by a sphere, or halo, of something else – something not visible, something dark. This stuff is called ‘dark matter’. Even though it is not visible, the author states, “We know that over 90 percent of material in galaxies like the Milky Way is dark matter….” Even when you add this generous fudge to the universe, “the density of the universe comes to about a third of the critical density.” The Big Bang theory predicted that if we were able to measure the velocity of galaxies over time, it would follow a profile one would expect of an energetic explosion – high velocity early, then a slowing as the energy of the explosion dissipated. The physicists devised a method by which they could observe more distant stars, where distance equates to farther looks into the past by their reckoning, and see what earlier velocities were. Unfortunately, there was a bombshell:Against all expectations, they found the most distant galaxies are receding from Earth more slowly than nearby ones… The expansion is accelerating!Enter fudge factor #2: “dark energy.” In order to make the expansion get faster later, physicists had to attribute to dark energy the ability to counteract the slowing force of gravity with an impulsive force that would boost the expansion enough to account for the faster current rates. The matter equivalent of dark energy (remember E=mc2 ?) fills up the rest of the matter required to bring the universe to critical density. This dark energy, by the way, is also invisible and unobservable. Between dark matter and dark energy, these fudge factors fill in gaps of 96 percent of what is observed in order to get old-age math to work out. This helps physicists feel optimistic that in a few tens of billions of years, we won’t Crunch or Chill.Evolutionists accuse creationists of inventing a “God of the Gaps” to cover for their ignorance of true science. It would appear that the high priests of astrophysics have their own Gods of the Gaps, namely dark matter and dark energy. What will happen to the universe? It won’t be the Big Crunch or the Big Chill, but the Big Furnace: “But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up. Since all these things are to be destroyed in this way, what sort of people ought you to be in holy conduct and godliness, looking for and hastening the coming of the day of God, because of which the heavens will be destroyed by burning, and the elements will melt with intense heat! But according to His promise we are looking for new heavens and a new earth, in which righteousness dwells” (2 Peter 3:10-13).—TC(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0

Arsenal manager Emery confirms plans for Holding, Bellerin & Tierneyby Freddie Taylora month agoSend to a friendShare the loveArsenal boss Unai Emery has confirmed Kieran Tierney and Hector Bellerin will soon play the club’s U23 side, while also confirming Rob Holding remains close to a return.Many expected Holding to line-up in Thursday’s Europa League clash with Eintracht Frankfurt.Speaking after the 3-0 victory in Germany, Holding said: “Rob Holding is getting closer to us now. Tomorrow, Hector Bellerin and Kieran Tierney will play with the under-23s.”On his make-shift defence, Emery added: “[Mustafi] played his first match this season and Chambers played at right back, David Luiz has now played with Mustafi and Chambers, with more players”I think every player can be important for us and I want to create a big spirit from games where we worked like we did tonight.” About the authorFreddie TaylorShare the loveHave your say
COLUMBIA, SC – NOVEMBER 14: A general view of the Florida Gators versus South Carolina Gamecocks during their game at Williams-Brice Stadium on November 14, 2015 in Columbia, South Carolina. (Photo by Streeter Lecka/Getty Images)Back in early November, it was announced that South Carolina freshman offensive tackle Na’Ty Rodgers had been dismissed from the program, and that he’d be transferring elsewhere to continue his football-playing career. It would appear, however, that he’s decided to take a parting shot on his way out.Rodgers, who has transferred to Iowa Western, claims that South Carolina’s training staff is “fake”, and that they misdiagnosed his knee injury. He claims that a doctor told him that he needs surgery, while the Gamecocks’ staff told him he was “fine” and that he could continue practicing.While it’s not completely surprising that a player who was dismissed from a program has beef with his former staff, this is a bit eye-opening. Hopefully South Carolina’s trainers just made an honest mistake.
The Palm Beach State College Foundation is proud to announce that Armando Christian Perez, professionally known as Pitbull, will be the keynote speaker for the Foundation’s 2017 STEAM (Science, Technology, Engineering, Arts and Math) luncheon presented by Bank of America.The event will take place February 1, 2017 at 11:30am at the Kravis Center for the Performing Arts’ Cohen Pavilion, West Palm Beach.“Everyone knows Pitbull is one of the most successful recording artists of our time, but what many don’t realize is that he is also a leading tech innovator and arts education proponent,” said event chair and nationally honored arts advocate, Yvonne Boice. “We are thrilled that he will be our speaker this year and that he will be sharing his inspiring success story that now melds so many aspects of the STEAM disciplines.”A first generation Cuban American, the young Perez was inspired by one of his high school teachers to pursue his musical dreams. Now, he wants to make sure other children are inspired and have that same opportunity to succeed.In 2013, Pitbull helped create the SLAM! (Sports, Leadership, Arts and Management) charter school in one of the Miami’s most impoverished neighborhoods. SLAM!, which educates students in grades 6-12, now has a school in West Palm Beach that could become a direct feeder to Palm Beach State College.Pitbull is also passionate about using and advancing technology. Besides utilizing social media to communicate with his fans and supporters, he is co-founder of eMerge Americas. This 3-year-old conference brings together high-tech firms from throughout the Americas to promote innovation and the development of disruptive technology across a myriad of industries.In 2017, the Foundation will enter the fifth year of its STEAM initiative to impact the projected shortage of local, skilled professionals in the STEAM fields. Goals include increasing student scholarships, business partnerships, internships and other academic program enhancements to prepare more graduates for these high-wage, high-demand positions.Sponsors of the event are: Bank of America, Modernizing Medicine, Florida Power & Light, Palm Beach Gardens Medical Center, Tenet Florida Physician Services, The Palm Beach Post, WXEL PBS for the Palm Beaches and Alpha Media.For ticket information, click here.Individual tickets purchased before Dec. 15 are $175; after Dec. 15 tickets are $200.
PARIS – France’s finance minister is defending a deal to merge French high-speed train maker Alstom with Germany’s Siemens as crucial to keeping European industry globally competitive.Finance and Economy Minister Bruno Le Maire told reporters Wednesday that the deal is especially important given growing competition from Chinese train makers to meet worldwide demand for the kind of high-speed trains once exemplified by Alstom’s TGVs.President Emmanuel Macron’s government is under fire over the Alstom deal because the French state owns 20 per cent of Alstom and has repeatedly intervened to save its jobs.Critics accuse the government of letting Germany buy out a French industrial champion.
ANCHORAGE, Alaska — The federal government’s attempt to sell oil leases in the National Petroleum Reserve-Alaska has again drawn a modest response.The Alaska Journal of Commerce reports the Bureau of Land Management on Wednesday received 16 bids on 16 tracts covering 272 square miles (705 sq. kilometres). BLM received seven bids in 2017.The BLM this year offered 254 tracts on more than 4,375 square miles (11,330 sq. kilometres).Federal officials say the modest bidding can be attributed to the lack of access to the most prospective areas.The sale took in $1.13 million.Environmental groups oppose expanded drilling in the reserve west of Prudhoe Bay.They say oil development will imperil caribou herds and ecologically significant wetlands used for breeding by migratory waterfowl from around the world.The Associated Press
