Thomas Hertog, a co-author of the study, told the BBC that he and Hawking were wrestling with the idea that the Big Bang actually resulted in the creation of multiple “pocket universes” that exist throughout space. It was unclear to them whether the laws of physics that apply in our universe would also apply in these alternate universes.
“In the old theory there were all sorts of universes: some were empty, others were full of matter, some expanded too fast, others were too short-lived. There was huge variation,” said Hertog, a physics professor at the Catholic University of Leuven (KU Leuven) in Belgium. “The mystery was why do we live in this special universe where everything is nicely balanced in order for complexity and life to emerge?”
Hertog and Hawking’s paper uses new mathematical techniques to restore order to previously chaotic views of the multiverse, suggesting that these different universes are subject to the same laws of physics as our own.
“It reduces the multiverse down to a more manageable set of universes which all look alike,” said Hertog, whose paper with Hawkings drew on 20 years of work.
The physicists also gave other researchers a pathway to potentially detect the presence of other universes by searching for cosmic microwave radiation that is left over from the Big Bang.
Hertog said that communication became more difficult near the end of Hawking’s life ― although the physicist apparently never showed signs of wanting to quit.
Along with his recently published study, Hawking has at least two other papers that are being prepared for publication, according to the Guardian.
Hawking died at the age of 76 on March 14, due to complications from amyotrophic lateral sclerosis, a progressive neurodegenerative disease. He rose to global fame in 1988, after publishing a general audience book on science, A Brief History of Time. In the world of astrophysics, he’s best known for his theories on black holes.
A man was killed by a rooster with a blade tied to its leg during an illegal cockfight in southern India, police said, bringing focus on a practice that continues in some Indian states despite a decades-old ban. The rooster, with a 3-inch knife tied to its leg, fluttered in panic and slashed its owner, 45-year-old Thangulla Satish, in his groin last week, police inspector B. Jeevan said Sunday. According to Jeevan, Satish was injured while he prepared the rooster for a fight.
Geddert, who had ties to disgraced team doctor Larry Nassar, was charged with 20 counts of human trafficking, one count of first-degree sexual assault, one count of second-degree sexual assault, criminal enterprise and lying to a police officer, according to court documents filed in Eaton County, Michigan. "We had hoped that news of the criminal charges being brought against John Geddert would lead to justice through the legal process," the sport's U.S. governing body said in a statement on Friday. "With the news of his death by suicide, we share the feelings of shock, and our thoughts are with the gymnastics community as they grapple with the complex emotions of this week's events."
State television announced that Myanmar's U.N. envoy had been fired for betraying the country, a day after he urged the United Nations to use "any means necessary" to reverse the Feb. 1 coup that ousted elected leader Aung San Suu Kyi. Myanmar has been in turmoil since the army seized power and detained Suu Kyi and much of her party leadership, alleging fraud in a November election her party won in a landslide. The coup, which stalled Myanmar's progress toward democracy, has brought hundreds of thousands of protesters onto the streets and drawn condemnation from Western countries, with some imposing limited sanctions.
Ted Cruz railed against "cancel culture" and mocked criticism of his trip to Mexico while his home state of Texas endured freezing conditions and power blackouts as he addressed the Conservative Political Action Conference (CPAC) on Friday. The Texas senator was widely criticised last week for taking a family trip to Cancun, Mexico while millions in his state went without heat or water after severe winter weather crippled power supplies. He cut his trip short and apologised for the trip after facing a public backlash. As he addressed CPAC attendees in Orlando, Florida, Mr Cruz began by referencing the controversy, joking: "Orlando is awesome. It's not as nice as Cancun - but it's nice." The comments were met with laughter from the audience.
Lady Gaga is poised to hand over a $500,000 reward to a mystery woman who returned her beloved French bulldogs kidnapped in a violent street robbery near her home in Hollywood. Koji and Gustav, thought to be worth up to $10,000 dollars each, were given in at a downtown LAPD Police Station by an unnamed woman late on Friday night. Authorities believe the woman who handed the dogs in was "uninvolved and unassociated" with the attack - but she is still eligible for the "unconditional" $500,000 and is said to be in contact with Gaga’s representatives. “If you bought or found them unknowingly, the reward is the same,” Gaga had said in a post confirming the hefty sum before the dogs were handed back on Friday. The violent abduction on Wednesday saw the singer’s dog-walker and close friend Ryan Fischer shot in the chest. Gaga's third dog named Miss Asia escaped the attack and was later found by police. The singer, whose real name is Stefani Joanne Angelina Germanotta, has kept silent since the dogs were handed into police. But her reward offer has raised eyebrows.
