'God particle' a gateway to new vision of universe

Physicists said Thursday the potential discovery of the "God particle" was a gateway to a new era that could see humanity unlock some of the universe's great mysteries including dark matter.

The European Organisation for Nuclear Research (CERN) unveiled data from the Large Hadron Collider on Wednesday "consistent with the long-sought Higgs boson", an elusive particle thought to help explain why matter has mass.

It was hailed as a huge moment for science by physicists gathered in Australia, where CERN's findings were unveiled via videolink from Geneva at a landmark conference attended by hundreds of the field's top experts.

Scientists went into a frenzy following the announcement, speculating that it could one day make light speed travel possible by "un-massing" objects or allow huge items to be launched into space by "switching off" the Higgs.

CERN scientist Albert De Roeck likened it to the discovery of electricity, when he said humanity could never have imagined its future applications.

"What's really important for the Higgs is that it explains how the world could be the way that it is in the first millionth of a second in the Big Bang," de Roeck told AFP.

"Can we apply it to something? At this moment my imagination is too small to do that."

Physicist Ray Volkas said "almost everybody" was hoping that, rather than fitting the so-called Standard Model of physics -- a theory explaining how particles fit together in the Universe -- the Higgs bosun would prove to be "something a bit different".

"If that was the case that would point to all sorts of new physics, physics that might have something to do with dark matter," he said, referring to the hypothetical matter some suggest makes up most of the mass in the universe.

"It could be, for example, that the Higgs particle acts as a bridge between ordinary matter, which makes up atoms, and dark matter, which we know is a very important component of the universe."

"That would have really fantastic implications for understanding all of the matter in the universe, not just ordinary atoms," he added.

De Roeck said scrutinising the new particle and determining whether it supported something other than the Standard Model would be the next step for CERN scientists.

Clarification could be expected by the beginning of 2013; definitive proof that it fitted the Standard Model could take until 2015 when the Large Hadron Collider (LHC) had more power and could harvest more data.

De Roeck said he would find it a "little boring at the end if it turns out that this is just the Standard Model Higgs".

Instead, he was hoping it would be a "gateway or a portal to new physics, to new theories which are actually running nature" such as supersymmetry, which hypothesises that there are five different Higgs particles governing mass.

The search for Higgs -- the logical next step of which de Roeck said would be searching for, and eventually being able to produce, dark matter particles -- has already had huge benefits to medicine and technology.

Volkas said the Internet was born at CERN as a solution to high-volume data-sharing and other major spin-offs were likely to follow as physicists continued to "push the boundaries of pure science".

"We just want to know how the world works, but in order to answer those questions you have to develop new technologies," he said.

Funding for particle physics is already under scrutiny in North America, where the LHC's predecessor, the Tevatron, was closed late last year due to financial constraints.

De Roeck said there were similar problems in Europe, where physicists will meet in September to discuss research priorities for the next 20 years and whether they need and can afford an accelerator after the LHC.

"That is going to be a tough fight," he said. "Despite this momentous moment we have now, it doesn't necessarily bring the funding which one would require." He urged governments and other key contributors to see fundamental science as a "must" rather than a luxury.

"This is the only way we can actually move on and have a deeper understanding of how things work. It can only be in our benefit exploring that."

    Philippines calls on ASEAN to urge China to halt land reclamation

    The Philippines called on its Southeast Asian neighbours to unite in urging China to halt reclamation of land in the South China Sea, but the call failed to raise widespread support ahead of a regional summit. China claims 90 percent of the South China Sea, which is believed to be rich in oil and gas. Its claims overlap with those of Brunei, Malaysia, the Philippines, Vietnam and Taiwan. Recent satellite images suggest China has made rapid progress in filling in land in contested territory …

    Indonesia defiant as UN leads condemnation of looming executions

    Indonesia on Sunday signalled it was determined to push ahead with the execution of eight foreign drug convicts, despite a growing wave of global condemnation led by United Nations chief Ban Ki-moon. Authorities on Saturday gave formal notice to the eight -- from Australia, Brazil, Nigeria and the Philippines -- that they would be executed by firing squad imminently, along with an Indonesian prisoner. The group have been moved to the high-security prison island of Nusakambangan, where …

    The Philippines on Sunday called on neighbouring Southeast Asian nations to push for an immediate halt to China's reclamation in the disputed South China Sea ahead of a regional summit. China claims 90 percent of the South China Sea, which is believed to be rich in oil and gas, with overlapping claims from Brunei, Malaysia, the Philippines, Vietnam and Taiwan. Recent satellite images suggest China has made rapid progress in building an airstrip suitable for military use in contested …

    The Philippine president said Sunday he would appeal for mercy for a Filipina who is due to be executed in Indonesia in two days' time. President Benigno Aquino said he would take the opportunity to seek clemency for Mary Jane Veloso, who is due to be put to death on Tuesday, while in Malaysia for a regional summit Monday. "Once I am there, I will try to speak to President Joko Widodo of Indonesia to appeal once more for her case," Aquino said. She was arrested in 2009 with 2.6 kilograms …

    United Nations Secretary-General Ban Ki-moon appealed to Indonesia on Saturday not to execute 10 prisoners, including two Australians, for drug-related crimes. Indonesia has so far informed seven of the 10 death row inmates, including the Australians and one Nigerian, that they will be executed in a matter of days, possibly as soon as Tuesday. Nationals from Brazil, Ghana and the Philippines are also on Indonesia's death row. A temporary reprieve was granted to a French citizen who will not …

    Beijing is poised to take "de facto control" of the South China Sea, the Philippines warned Sunday, but its call for a robust Southeast Asian response at a regional summit was shot down. Vietnam, the Philippines, Malaysia and Brunei claim parts of the strategic body of water, but Beijing claims nearly all of it, and its increasingly strident territorial assertions have caused concern in the region and beyond. "(China) is poised to consolidate de facto control of the South China Sea," …

    The United States has asked for access to Philippine military bases in eight locations to rotate troops, aircraft and ships as Washington shifts its forces to Asia and as China expands its military presence in the South China Sea. US Defense Secretary Ash Carter, in a speech in Arizona, has outlined Washington’s next phase in its Asia “pivot,” deploying its most sophisticated destroyers, bombers and fighters to the region. The Asia “pivot” has already seen US Marines rotating through the …
