(KGTV) - A professor who made disparaging racial remarks toward a student may be returning to the San Diego State University campus after a forced hiatus.Professor Oscar Monge is scheduled to teach three writing classes in the American Indian Students department for Fall 2018, according to registration records.Monge was suspended in the beginning of 2018 after the California Attorney General's Office said he made discriminatory remarks toward a white student.He referred to white student as a "white savior," a black student as an "Uncle Tom," and another as a "Cherokee princess" according to a state investigator’s report.RELATED: Professor makes?"racial insensitive" remarksA spokesperson for SDSU provided a statement to 10News:“A faculty listing does not constitute a confirmed appointment. The university will begin to process temporary faculty appointments for Fall 2018 during the month of July."Crystal Sudano, one of the students who Monge made comments toward, said this is bad idea.“How much more abuse is San Diego State going to take?” said Sudano, “He’s got everybody by the gonads and everybody’s afraid to do anything.”Monge is currently on administrative leave and has not returned multiple requests by 10News for comment. 1297

(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) - Can Tito's Vodka really be used in an effective homemade hand sanitizer?No.Social media posts are going around recommending people use the booze in do-it-yourself sanitizer recipes.But Tito's put out a tweet noting that CDC guidelines recommend hand sanitizer contain at least 60% alcohol. Tito's only has 40%.The CDC says washing your hands is by far the best way to get rid of germs. But if you use a hand sanitizer, make sure it meets that 60% alcohol threshold. 483

(KGTV) - California regulators are considering a plan to charge a fee for text messaging on mobile phones to help fund programs that make phone service accessible to the poor.The California Public Utilities Commission (CPUC) is set to consider the proposal in a vote scheduled for next month, according to The Mercury News. It's not clear how much mobile phone users would be asked to pay under the proposal, but it would likely be billed as a flat surcharge, not a per-text fee, according to the paper.And wireless industry and business groups are not "LOLing." The groups are reportedly already trying to defeat the proposal before it makes its way to the commission.“It’s a dumb idea,” Jim Wunderman, president of the Bay Area Council business-sponsored advocacy group, told the Mercury News. “This is how conversations take place in this day and age, and it’s almost like saying there should be a tax on the conversations we have.”The new surcharges could generate a total of about .5 million a year, according to business groups. The same groups warned that under the proposal's language, the charge could be retroactively be applied for five years, totaling more than 0 million for consumers, the paper reported.Click here for a look at the proposal.The proposal argues that the state's Public Purpose Program budget has increased from 0 million in 2011 to 8 million in 2016, while revenues funding the program from the telecommunications industry saw a "steady decline" from .5 billion in 2011 to .3 billion in 2017.The report calls this "is unsustainable over time."In a statement to the Associated Press, CPUC spokeswoman Constance Gordon said, "from a consumer's point of view, surcharges may be a wash, because if more surcharge revenues come from texting services, less would be needed from voice services." 1845
