(KGTV) - Did U.S. soccer star Megan Rapinoe stomp on the American Flag following the team's World Cup victory?No.During the postgame celebration, Rapinoe's teammate Allie Long briefly dropped the flag on the ground while Rapinoe was playing to the crowd.While video shows her foot may have inadvertently touched the flag, she certainly didn't stop on it.The U.S. Flag Code says the flag should never touch the ground.But this was clearly not a malicious act. 466

(KGTV) - A 6.5 earthquake struck off the coast of Costa Rica on Sunday night, according to the US Geological Survey.The quake was centered 16 km west of Jaco, Costa Rica, at a depth of 10 km, said?the USGS. It gave the quake preliminary magnitude of 6.8, but later downgraded it.Jaco lies southwest of Costa Rica's capital, San Jose, and is part of the region of Puntarenas, on the Pacific Coast.RELATED: 140 dead in quake along Iran-Iraq borderThe President of Costa Rica, Luis Guillermo Solís, tweeted that no tsunami warning had been issued.CNN contributed to this report. 583

(KGTV) -- A Central Valley man has been arrested for reportedly attempting to join ISIS, according to KGO.The man, identified as Bernard Raymond Augustine, 20, from Keyes, California was arrested on charges of providing material support to terrorists.Augustine was taken into custody while trying to enter Libya to join the Islamic State terrorist group.Augustine is expected to make his first appearance in federal court in Brooklyn Tuesday, according to authorities.Records show that Augustine told U.S. Customs he was going to Tunisia, where he was later arrested, for a vacation.After searching through his computer, authorities discovered a song that praised ISIS and messages sent by Augustine that seemed to do the same. 740

(CNN) -- Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds.This theory has now been toppled by LB-1, the newly-discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday."Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1's sheer size suggests that it "was not formed from the collapse of only one star," the study said -- instead, it could potentially be two smaller black holes orbiting each other.Another possibility is that it formed from a "fallback supernova." This is when a supernova -- the last stage of an exploding star -- ejects material during the explosion, which then falls back into the supernova, creating a black hole.This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.LB-1 is not the biggest black hole ever discovered -- but it may be the largest of its kind. There are several types of black holes, and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger -- they can be billions of times the mass of our sun.Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the massive star systems -- but it is still not clear exactly how, or which form first.Stellar renaissanceStellar black holes are believed to be commonly scattered across the universe, but they are difficult to detect because they do not normally emit X-rays -- only doing so when they gobble up gas from a star that has ventured close enough. They are so elusive that scientists have only found, identified, and measured about two dozen stellar black holes, the press release said.The researchers at the Chinese Academy of Sciences tried a different approach. Instead of looking for X-rays emitted by black holes, the team looked for stars that were orbiting some invisible object, being pulled in by its gravity.Their efforts paid off -- they soon spotted a giant star eight times heavier than the sun, orbiting around what turned out to be LB-1."This discovery forces us to re-examine our models of how stellar-mass black holes form," said David Reitze, a physicist at the University of Florida. In May, Reitze's team made its own breakthrough discovery -- observing the never-before-seen collision of a neutron star and a black hole, which sent out ripples in space and time.These twin discoveries -- the collision, and now LB-1 -- indicate that scientists are reaching "a renaissance in our understanding of black hole astrophysics," said Reitze in the press release.There have been several other discoveries over the past year that have added to this renaissance. In October, researchers discovered what they believe to be a new type of black hole, smaller than the other kinds. And earlier this week, astronomers discovered a black hole that is actually helping baby stars grow instead of destroying them. 3971

(KGTV) -- A man from Louisiana died after proposing to his girlfriend underwater during a vacation to Tanzania, CNN reports. Steven Weber and Kenesha Antoine were staying in a wooden cabin with a bedroom submerged beneath the surface of the water off the east coast of Africa when the incident occurred. According to CNN, Weber proposed Thursday by swimming underwater, holding a handwritten note against one of the bedrooms windows. "I can't hold my breath long enough to tell you everything I love about you. BUT...Everything I love about you I love more EVERY DAY,” the note read in part. Weber then failed to return to the surface, Antoine wrote in a post on Facebook. "You never emerged from those depths, so you never got to hear my answer, 'Yes! Yes! A million times, yes, I will marry you!!' " she wrote.The resort the couple was staying in confirmed the death in a statement Saturday. 903
