A US weapons lab on Friday pulled back the curtain on a super laser with the power to burn as hot as a star.
The National Ignition Facility’s (NIF) main purpose is to serve as a tool for gauging the reliability and safety of the US nuclear weapons arsenal but scientists say it could deliver breakthroughs in safe fusion power.
“We have invented the world’s largest laser system,” California Governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands of people including state and national officials.
“We can create the stars right here on earth. And I can see already my friends in Hollywood being very upset that their stuff that they show on the big screen is obsolete. We have the real stuff right here,” he said.
The NIF is touted as the world’s highest-energy laser system and is inside the Lawrence Livermore National Laboratory, about an hour drive from San Francisco.
Equipment connected to a house-sized sphere can focus 192 laser beams on a small point, generating temperatures and pressures that exist at cores of stars or giant planets.
The NIF will be able to create conditions and conduct experiments never before possible on Earth, the lab said.
A fusion reaction triggered by the super laser hitting hydrogen atoms will produce more energy than was required to prompt “ignition,” NIF director Edward Moses said.
“This is the long-sought goal of ‘energy gain’ that has been the goal of fusion researchers for more than half a century,” Moses said.
“NIF’s success will be a scientific breakthrough of historic significance; the first demonstration of fusion ignition in a laboratory setting, duplicating on Earth the processes that power the stars,” he said.
Construction of the NIF began in 1997, funded by the US Department of Energy National Nuclear Security Administration (NNSA).
“NIF, a cornerstone of the National Nuclear Security Administration’s effort to maintain our nuclear deterrent without nuclear testing, will play a vital role in reshaping national security in the 21st century,” NNSA administrator Tom D’Agostino said. “This one-of-a-kind facility is the only place in the world that is capable of providing some of the most critical technical means to safely maintain the viability of the nation’s nuclear stockpile.”
Lab scientist maintain that the NIF also promises groundbreaking discoveries in planetary science and astrophysics by recreating conditions that exist in supernovas, black holes and in the cores of giant planets.
Electricity derived from fusion reactions similar to what takes place in the sun could help sate humanity’s growing appetite for green energy, lab officials said.
“Very shortly we will engage in what many believe to be this nation’s greatest challenge thus far, one that confronts not only the nation but all of mankind — energy independence,” lab director George Miller said.
The lab was founded in 1952 and describes itself as a research institution for science and technology applied to national security.
“This laser system is an incredible success not just for California, but for our country and our world,” Schwarzenegger said.
Archeologists in Peru on Thursday said they found the 5,000-year-old remains of a noblewoman at the sacred city of Caral, revealing the important role played by women in the oldest center of civilization in the Americas. “What has been discovered corresponds to a woman who apparently had elevated status, an elite woman,” archeologist David Palomino said. The mummy was found in Aspero, a sacred site within the city of Caral that was a garbage dump for more than 30 years until becoming an archeological site in the 1990s. Palomino said the carefully preserved remains, dating to 3,000BC, contained skin, part of the
TRUMP EFFECT: The win capped one of the most dramatic turnarounds in Canadian political history after the Conservatives had led the Liberals by more than 20 points Canadian Prime Minister Mark Carney yesterday pledged to win US President Donald Trump’s trade war after winning Canada’s election and leading his Liberal Party to another term in power. Following a campaign dominated by Trump’s tariffs and annexation threats, Carney promised to chart “a new path forward” in a world “fundamentally changed” by a US that is newly hostile to free trade. “We are over the shock of the American betrayal, but we should never forget the lessons,” said Carney, who led the central banks of Canada and the UK before entering politics earlier this year. “We will win this trade war and
‘BODIES EVERYWHERE’: The incident occurred at a Filipino festival celebrating an anti-colonial leader, with the driver described as a ‘lone suspect’ known to police Canadian police arrested a man on Saturday after a car plowed into a street party in the western Canadian city of Vancouver, killing a number of people. Authorities said the incident happened shortly after 8pm in Vancouver’s Sunset on Fraser neighborhood as members of the Filipino community gathered to celebrate Lapu Lapu Day. The festival, which commemorates a Filipino anti-colonial leader from the 16th century, falls this year on the weekend before Canada’s election. A 30-year-old local man was arrested at the scene, Vancouver police wrote on X. The driver was a “lone suspect” known to police, a police spokesperson told journalists at the
North Korean leader Kim Jong-un has unveiled a new naval destroyer, claiming it as a significant advancement toward his goal of expanding the operational range and preemptive strike capabilities of his nuclear-armed military, state media said yesterday. North Korea’s state-run Korean Central News Agency (KCNA) said Kim attended the launching ceremony for the 5,000-tonne warship on Friday at the western port of Nampo. Kim framed the arms buildup as a response to perceived threats from the US and its allies in Asia, who have been expanding joint military exercises amid rising tensions over the North’s nuclear program. He added that the acquisition
