Conclusion: all 3 were wrong.The last Apollo mission left scientists with many questions. Artwork by Alan Bean, Apollo 12 astronaut.In the 1960s, there were three competing theories for how the moon formed: (1) it spun off the Earth (fission theory), (2) it formed at the same time as Earth (co-formation theory), or (3) it was captured by the Earth (capture theory). Now, most planetary scientists reject all three theories in favor of the Giant Impact theory. Sometime in unseen history, they allege, a Mars-sized body impacted the Earth and spun off material that formed the moon. This theory became popular around 2000, decades after Apollo, although some simulations suggested it around 1980. In some versions, the impactor brought water to the Earth, creating our oceans.It may be the most popular idea, but the Giant Impact theory is not without huge problems of its own. For one, an impactor would have to be just the right size, and would have to approach the Earth at a finely-tuned speed, angle and position in order to work. Otherwise, it would either speed by the Earth, merge with it, or obliterate it. Computer models can be intelligently designed to achieve the desired result, but how realistic are they? That’s only one of many mysteries for those wishing to limit their explanatory toolkit to the Stuff Happens Law (i.e., chance). Even so, they will admit that we were awfully lucky to have a moon, because without it, we would not be here.Lucky Break?Other than Pluto (which is lifeless), no other planet in our solar system has a moon as relatively large as ours. Because of its size and distance from Earth, our moon gives us at least three outstanding benefits. It stabilizes our axis of rotation, giving us reliable seasons so that solar heat is distributed efficiently around the globe in a predictable way. It is the main contributor to ocean tides that cleanse our coastlines and create oceanic currents used by marine life and by sailors. It also creates ideal conditions for solar eclipses—unique phenomena among all the bodies in the solar system—which are not only awesome to behold but also provide unique opportunities for scientific discovery (see The Privileged Planet book and film; the documentary can be watched on YouTube).Many see these benefits as indicators of intelligent design and foresight. Secular scientists, preferring to remain materialists, just say we are lucky. But accounting for the moon by sheer dumb luck doesn’t help science. It actually creates more problems that remain baffling 50 years after Apollo was supposed to solve them.Earth Has WAY More Gold Than the Moon and Here’s Why (Space.com). There are two problems emerging from low lunar quantities of gold and other siderophile (iron-loving) elements: (a) The debris from the Giant Impact should have spread these elements to both the Earth and Moon equally, and (b) The Earth’s abundances should have sunk into the core, but are largely at the surface. How do secularists explain these facts? The article invokes several theory-rescue devices to get around the problems. For one, they allege that these elements arrived later by asteroids. Then why didn’t the moon get them, too? For the next rescue device, they allege that the Earth, with its higher gravity, was better at holding onto its siderophiles than the moon was.“This has been a major problem in terms of how we understand the moon’s accretion history,” Qing-zhu Yin, a professor of earth and planetary sciences at the University of California, Davis, said in a statement.See also the press release from UC Davis that includes Qing-zhu Yin’s boast,Neil Armstrong planting the American flag on the moon. Artwork by Alan Bean, Apollo 12 astronaut. Used by permission.Reconstructing the late-accretion history of the Moon (Nature). Here’s the paper for the above article. Calling on Lady Luck, it models “random impactors” coming in to bring Earth’s gold special delivery after the moon had formed. They first state the problems facing theorists:The importance of highly siderophile elements (HSEs; namely, gold, iridium, osmium, palladium, platinum, rhenium, rhodium and ruthenium) in tracking the late accretion stages of planetary formation has long been recognized. However, the precise nature of the Moon’s accretional history remains enigmatic. There is a substantial mismatch in the HSE budgets of the Earth and the Moon, with the Earth seeming to have accreted disproportionally more HSEs than the Moon. Several scenarios have been proposed to explain this conundrum, including the delivery of HSEs to the Earth by a few big impactors, the accretion of pebble-sized objects on dynamically cold orbits that enhanced the Earth’s gravitational focusing factor, and the ‘sawtooth’ impact model, with its much reduced impact flux before about 4.10 billion years ago. However, most of these models assume a high impactor-retention ratio (the fraction of impactor mass retained on the target) for the Moon.And thus they go, weaving new scenarios they hope will work. They tweak their models by adjusting the size of the impactors, their arrival times and other knobs, then run a “Monte Carlo simulation” (more Lady Luck) that tapers off to get the results they want. “The combination of a low impactor-retention ratio and a late retention of HSEs in the lunar mantle provides a realistic explanation for the apparent deficit of the Moon’s late-accreted mass relative to that of the Earth,” they boast. The boasting will probably last until the next critic comes along. Qing-zhu Yin actually admits this: ““The beauty of this work is such that all of these things are now coming together nicely. We may have solved this problem, at least until someone find [sic] new discrepancies!” Yin said in a press release from UC Davis.Note: no actual observations were conducted outside the computer. They use various forms of the word assume (assuming, assumption) 33 times, usually in the form, “we assume.”Tomorrow, we will look at more “lunar tunes” coming from the Stuff Happens crowd.

Senior attackman Katie Chase (11) handles the ball during a game against Northwestern March 9 at Ohio Stadium. OSU won, 11-10.Courtesy of OSU AthleticsFrom the first drop of the ball, Katie Chase had one thing on her mind: scoring goals.The senior attackman for the Ohio State women’s lacrosse team turned in a career-high seven goals on her way to eight points as the No. 18 Buckeyes topped Oregon, 13-9, Wednesday at Jesse Owens Memorial Stadium.High winds wreaked havoc on play throughout the entirety of the game, leading OSU coach Alexis Venechanos to attribute much of the team’s success against the Ducks (4-4, 1-0) to Chase’s work on and off the ball.Venechanos described Chase as a “special player” that had a “really strong game.”“She took over parts of that game in the draw control,” Venechanos said after the game. “Her teammates looked for her and she shot phenomenally.”The Buckeyes (7-4, 1-1) got off to a quick start, gaining possession of the ball off the game’s first draw. Chase set the pace for the match early by scoring the game’s first goal 23 seconds into the game.“We always want to score first,” Venechanos said. “That was important to start like that.”Chase said setting the tone early is a goal OSU has every game, and she felt they were able to do that with a quick goal from the start.“It gets the beat up for our attack and gets us in the flow of things,” Chase said after the win.The momentum from Chase’s quick strike didn’t continue, however, as the Ducks responded with two goals in just less than five minutes to take a 2-1 lead.But OSU, lead by Chase — who completed a hat trick before the half ended — struck back to take a 4-2 lead before Oregon evened the count with 11:06 left in the first half.OSU senior attackman Cara Facchina tallied her third goal of the season at the 2:29 mark in the first, though, to give the Buckeyes a one-goal advantage heading into the break.“They would answer, then we would answer,” junior goalie Tori DeScenza said on the first half. “But we really (hunkered) down knowing that they were going to swing the ball pretty fast.”Along with hard work on the offense, the Buckeyes gained their success with the defensive mentality around the field forcing numerous turnovers from Oregon’s strong attack.“We haven’t seen an attack like them,” Venechanos said. “We really had trouble with it.”The Ducks’ strong attack tested the OSU defense, but the Buckeyes maintained composure and were able to gain more possessions to help secure the victory.Part of that defense was DeScenza, who fought hard in the net all throughout the game and ended the game with 10 saves.The game was the first ever between the two programs.DeScenza credits Oregon with its good stick skills but was proud of how hard the defense worked to combat them.“It was a hard battle all the way to the final whistle,” DeScenza said.The Buckeyes head back to work to prepare for a match against William and Mary set for noon Saturday at Jesse Owens Memorial Stadium.

Last season’s Champions League runners-up will face Torino at Anfield on August 7 in their final pre-season friendly, before they take on West Ham United in their Premier League opener just five days later.“Although these two weeks don’t seem like a long time, it’s enough for us to be ready for our first game against West Ham,” said Allison.“We’ll play two friendlies before this game and I’m sure the hard work the squad have put in so far is going to help me become a member of the squad as quickly as possible so that I am 100 percent ready for our first game to kick off the Premier League in a good way.“This initial training session has been useful for me to see what our playing style should be in the Premier League.“It’s also showed me that the team are very well adapted to it and everyone seems to be physically fit, not to say technically — they’re all great players after all.“I’m very happy to have them alongside me and to be a part of this project that Liverpool have and the great work they have been doing over recent years.“I hope I can help and bring something extra to the team.”
With a dominant performance against Al Ain, Real Madrid becomes the only club in history to win three consecutive FIFA Club World Cups.During a season that has been as difficult as the one Real Madrid is experiencing at the moment, Los Blancos desperately needed the FIFA Club World Cup in the final against Al Ain to boost their confidence during the post-Ronaldo era.The Arab club surprised the world when they managed to defeat River Plate in the semifinals, which gave them the right to play this match against Santiago Solari’s squad, but this is as far as they were going to get.The truth is that Real Madrid was way too superior and the Arabs had absolutely no chances to defeat the Spanish giants, they did make them suffer during the first 60 minutes of the match and only a long distance screamer in the first half from Modric was able to keep them ahead in the scoreline before a full hour had passed.The shot that the Croatian midfielder took just before the 15-minute mark, was the perfect culmination to an already fantastic year he has as an individual player.However, Los Blancos still didn’t have a secured result and they required to push themselves further in order to get more goals that could make them feel more confident.¡REAL MADRID, TRICAMPEÓN DEL MUNDO!El momento esperado por los merengues: ¡Cuando levantan el título como campeones del #MundialdeClubesxFOX!Revívelo pic.twitter.com/gxd4dvESY6— FOX Sports MX (@FOXSportsMX) December 22, 2018Already in the second half, it was a beautiful long-distance volley from Marcos Llorente what gave Los Blancos that confidence they needed.The Real Madrid product has been playing amazing football under Santiago Solari this season, this goal is a reward for that effort he’s been making in order to get noticed.But a Real Madrid final cannot be completed without a Sergio Ramos header during a corner kick, the magical moment happened just before the 80-minute mark after Luka Modric sent a cross straight into Ramos’ head.The skipper has now scored goals in two Champions League finals, two European Supercup final, and two Club World Cup finals as well.It was 3-0 already, Los Blancos had secured their result and another trophy for the museum inside the Santiago Bernabeu.But the final still wasn’t over, Al Ain did score a goal near the end of the match through Shiotani in order to at least find a little comfort in a very difficult night for them.Mourinho: “Lionel Messi made me a better coach” Andrew Smyth – September 14, 2019 Jose Mourinho believes the experience of going up against Barcelona superstar Lionel Messi at Real Madrid made him a greater coach.Los Blancos still got a fourth goal after the 90th minute, they got it through an own goal scored by Yahia Nader.EL CAMINO AL TRICAMPEONATO #MundialdeClubesxFOX Así fue la goleada del Real Madrid al Al Ain en la Final⚽ – Modric (14′) ⚽ – Llorente (60′) ⚽ – Ramos (79′) ⚽ – Shiotani (86′) ⚽ – Nader [AG] (90′) pic.twitter.com/dBoXAQYywx— FOX Sports MX (@FOXSportsMX) December 22, 2018This 4-1 result was the final nail on Al Ain’s coffin, the one that sealed the result for Real Madrid and got them to claim the FIFA Club World Cup for the third consecutive time.Santiago Solari clearly stepped in with the right foot as the manager for this squad, he also reached a historic milestone that only four other managers have been able to accomplish it.The Argentine manager won the Intercontinental Cup back in 2002 as a Real Madrid player, today he wins the equivalent competition as a manager and writes his name next to the likes of Luis Cubilla, Juan Mujica, Carlo Ancelotti, and Zinedine Zidane.All five men were able to win the same competition both as players and managers.This result is worthy of celebration for Los Blancos, they will travel back to Spain and rest for the holidays but they will have to go back to reality soon after.This club is not doing so well in La Liga right now, maybe this new trophy can give them the boost they need in order to improve their results during the year of 2019.Congratulations to Real Madrid, they are the World Champions for the third consecutive year.🏆🎉 ¡CAMPEONES DEL MUNDO! #RMCWC | #HalaMadrid pic.twitter.com/MCwui6I5Mw— Real Madrid C.F.⚽ (@realmadrid) December 22, 2018Who was the player you liked the most in the final between Real Madrid and Al Ain?

Cardiff City manager Neil Warnock says they were unlucky not to have been awarded a penalty in their goalless draw with Huddersfield Town on Saturday.Despite Warnock’s claims, Cardiff City should count them lucky after referee Lee Mason overturned a penalty he awarded to Huddersfield Town in the 76th minute.Cardiff felt they were denied clear penalty calls when Philip Billing’s header hit Erik Durm’s arm and when Hoilett was brought down by Hadergjonaj.“We knew we’d be struggling a little bit today,” Warnock told Sky Sports.“We had one or two players who shouldn’t have been playing. Callum Paterson and Victor Camarasa weren’t really fit but I wanted to play them.Cowley explains why he changed his mind about Huddersfield Manuel R. Medina – September 9, 2019 Last week Danny Cowley rejected the chance to coach Huddersfield Town in the English Championship, but today he accepted saying it was a good opportunity.“I thought we had the opportunities but we didn’t get the rub of the green although thankfully the linesman was alert to overturn the penalty. We thought ours was a certain penalty for a foul on [Junior] Hoilett.“The lad doesn’t see him coming, he gets to the ball first, and he takes the man.“I don’t understand why they can’t be given but I suppose next season with VAR, we’ve got a chance.”

Nirmala Sitharaman delivering her budget speech.TwitterUnion Finance Minister Nirmala Sitharaman proposed on Friday, July 5, tax deduction at source (TDS) of two per cent on cash withdrawals exceeding Rs 1 crore in a year from a bank account. “Our Government has taken a number of initiatives in the recent past for the promotion of digital payments and less cash economy,” said Sitharaman, while presenting her first Union Budget. The decision was made to promote digital payments and curb black money.The Finance Minister also proposed that business establishments with an annual turnover of more than Rs 50 crore shall offer low-cost digital modes of payment to their customers and no charges or Merchant Discount Rate (MDR) shall be imposed on customers as well as merchants.”RBI and banks will absorb these costs from the savings that will accrue to them on account of handling less cash as people move to these digital modes of payment,” Sitharaman said.”Necessary amendments are being made in the Income Tax Act and the Payments and Settlement Systems Act, 2007 to give effect to these provisions,” she added.
File photo of LightningSix people from the same family were “killed on the spot” by a lightning strike in Madagascar over the weekend while sheltering from a storm, officials said Monday.The relatives — including a three-year-old child — were killed in the central village of Bakaro on Saturday. Another person suffered superficial burns.”Twenty-five farmers sheltering from rain under a thatched cottage after leaving their rice field were hit by a lightning bolt,” said medical inspector William Patrick Rakotondralambo of the Fitsinjovana commune.”Six people from the same family were killed on the spot, including a three-year-old child,” he added.Eight survivors were treated for shock, Rakotondralambo said.Lightning strikes are relatively common in Madagascar, an Indian Ocean island famed for its unique wildlife and well-known for its vanilla and precious redwood.
