(KGTV) - Did a woman really post a flier offering her services as a babysitter for "white kids only?"No.While the flier says Debra Allen, it actually shows a picture of an Oregon woman named Amber Lee Hughes.She told the "Eugene Weekly" that it was likely an ex-boyfriend who created the fake flier.Hughes says the blowback from the flier has forced her to change her phone number.She says not only is she not racist, she doesn't even work as a babysitter any more. 473

(KGTV) - Did a 6-year-old YouTube star from South Korea really buy an million home?Yes.Boram has 31 million subscribers for her videos which feature toy reviews and a video blog.She generates about million a month from her videos, which she makes with her family.Through her parents, she purchased an million five-story property in Seoul earlier this year. 373

(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 family forced to flee Paradise, Calif., because of the Camp Fire finally returned home after nearly a month this week to find their faithful canine had survived and guarding their charred property.Andrea Gaylord was evacuated on Nov. 8 but only allowed back to her property Wednesday, according to group K9 Paw Print Rescue. Her property had burned in the fire. During the evacuation, Gaylord was unable to get to her dog, Madison, before the flames had spread through the town and forced her out, according to the rescue group.Animal rescuer, Shayla Sullivan, responded to Gaylord's request to check on Madison, first spotting the Anatolian shepherd just days after the fire began. Madison, however, kept his distance, according to Sullivan, who was already in the area searching for other lost pets.Sullivan decided to leave food and water regularly at the property for Madison until Gaylord was able to return, the animal group wrote.As Gaylord pulled up Wednesday, there sat Madison — being a very good boy."He had stayed to protect what was left of his home, and never gave up on his people! I’m so happy I’m crying as I write this! He didn’t give up through the storms or the fire! A long [sp] month it must have been for him!" Sullivan wrote on Facebook. 1280

(CNN) -- It may seem like an ordinary scene: Children and adults playing on pink seesaws, carelessly laughing and chatting with each other.But this is a playground unlike any other. These custom-built seesaws have been placed on both sides of a slatted steel border fence that separates the United States and Mexico.The idea for a "Teeter-Totter Wall" came from Ronald Rael, an architecture professor at the University of California, Berkeley, and Virginia San Fratello, an associate professor of design at San Jose State University -- and it was a long time coming.In 2009, the two designed a concept for a binational seesaw at the border for a book, "Borderwall as Architecture," which uses "humor and inventiveness to address the futility of building barriers," UC-Berkeley said.Ten years later, their conceptual drawings became reality. Rael and his crew transported the seesaws to Sunland Park, New Mexico, separated by a steel fence from Ciudad Juárez, Mexico.People from both sides came together Monday to play in a "unifying act," the University of California said in a statement. Participants on the Mexico side had no planning, it said.In an Instagram post, Rael said the event was "filled with joy, excitement, and togetherness at the borderwall.""The wall became a literal fulcrum for U.S -Mexico relations and children and adults were connected in meaningful ways on both sides with the recognition that the actions that take place on one side have a direct consequence on the other side," he wrote.Rael says that counterproposals for the wall created by his studio "reimagine, hyperbolize, or question the wall and its construction, cost, performance and meaning," according to the book's website. 1719
