(KGTV) — If you've been longing for movie night at the theater, but want to ensure no crowds, AMC is offering an interesting proposition.To soften the hit of the pandemic, the movie theater chain is offering private theater rentals for up to 20 people starting at and increasing to 9, depending on the movie, location, and add-ons. Add-ons include adding a microphone to greet guests (0) or more time to use the auditorium than the standard 15 minutes prior to the showing (0 per half hour). The personal screenings are available for 17 movies, with several Halloween-themed flicks and recent releases. like "Tenent" and "The New Mutants."In San Diego County, the option is available at theaters including:Chula Vista - Chula Vista 10Chula Vista - Otay Ranch 12La Jolla - La Jolla Village 12National City - Plaza Bonita 14Poway - Poway 10San Diego - Fashion Valley 18San Diego - Mission Valley 20San Diego - Palm Promenade 14AMC's move comes as the theater chain struggles to stay afloat during pandemic-related closures and capacity limits inside businesses.RELATED: AMC warns it could run out of cash by end of year, says reportsThis month, AMC warned that its existing cash resources would be "largely depleted" by the end of this year or early next year. The company said it would either need to sell more tickets or find new ways to borrow money to keep running.About 500 of AMC's 600 theaters that have reopened are held to capacity limits between 20% - 40% depending on local restrictions.Meanwhile, Cineworld Group, which owns Regal Cinemas, said this month that it will suspend operations at all of its U.S. and United Kingdom theaters due to the pandemic. Movie studios also continue to avoid theatrical releases, with several anticipated releases like "Marvel's Black Widow" and the new James Bond movie "No Time to Die" being delayed until next year. 1883

(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) — California voters have rejected a measure that would reinstate affirmative action based on race and gender.Proposition 16 would have ended the ban on affirmative action, allowing state and local entities to consider race, sex, color, ethnicity, and national origin in public education, public employment, and public contracting — to the extent allowed under federal and state law.Californians voted against the measure 56% to 44%, with 72% of precincts reporting.Critics of the proposition pointed to a previous prop, Prop 209, as to why Californians should vote against it.“The state shall not discriminate against, or grant preferential treatment to, any individual or group on the basis of race, sex, color, ethnicity, or national origin, in the operation of public employment, public education, and public contracting,” opposition stated in reference to a passage from Prop 209. 899

  

(KGTV) - An earthquake struck northern Mexico’s Baja California peninsula Monday, causing tremors felt in San Diego County.The 4.8 quake was located near Alberto Oviedo Mota at 12:18 p.m.The initial quake was followed by a 3.3 aftershock in the same area seven minutes later.Alberto Oviedo Mota is roughly 160 miles from San Diego. According to the U.S. Geological Survey, the shaking in San Diego County was in the II-III or IV categories, meaning weak to light. The strongest shaking reported in the U.S. was in El Centro, which was considered moderate.There are no immediate reports of damage or injuries. 626

  

(KGTV) - Is a company now printing your face on a coronavirus mask so you can still unlock your phone using facial recognition?No.A San Francisco artist created the masks as a joke and it went viral.She even set up a website that now has 1,200 people on a wait list to buy the masks.But she has no set plans to make them, and experts say they wouldn't work anyway on most phones. 387
