Particle physicists were jubilant yesterday after the long-awaited startup of a mega-machine designed to expose secrets of the cosmos passed its first test with flying colors.
Cheers, applause and the pop of a champagne cork — rather than the cataclysmic suck of a black hole, as doomsayers had feared — marked the breakthrough at the European Organisation for Nuclear Research (CERN).
CERN director general Robert Aymar hailed it as a “historic day” for the organization and humankind’s thirst for knowledge.
Humans have “a quest for [knowing] where they came from and where they should go, whether the universe will end, and where the universe will go in the future,” he said.
Just after 7:30am, the first proton beam was injected into the Large Hadron Collider, built 100m underground at CERN headquarter.
The mission aims to resolve some of the greatest enigmas in physics: whether a so-called “God particle” exists that would account for the nature of mass; an explanation for “dark matter” and “dark energy” that account for 96 percent of the cosmos; and whether other dimensions exist in parallel to our own.
In a 27km circular tunnel on the Swiss-French border, parallel beams of protons will be accelerated to nearly the speed of light.
Superconducting magnets will then steer the counter-rotating beams so that strings of protons smash together in four huge laboratories, fleetingly replicating the conditions that prevailed at the “Big Bang” that created the universe 13.7 billion years ago.
Arrays of detectors will trace the sub-atomic rubble spewed out from the collision, looking for signatures of novel particles.
CERN scientists have dismissed fears that the process could create a “black hole,” whose super-gravity would swallow the Earth.
Yesterday’s startup marked the start of a long and cautious commissioning process to check equipment and operational procedures before these collisions can get under way.
The first batch of protons was halted, sector by sector, to verify that monitoring systems and the steering magnets were working properly. Their speed was purposely slowed for the inspection process.
The clockwise beam completed this first test lap in under an hour, causing an eruption of joy and an outbreak of bubbly in the control room.
“No one would have imagined that this could have been done in less than an hour. It’s phenomonenal, quite unbelievable,” an operator said.
“We are very happy and proud,” the operator said.
By comparison, the predecessor to the LHC at CERN, the Large Electron Positron collider, took 12 hours to achieve the same goal.
A test of the anticlockwise beam was to take place later yesterday, scientists said.
MORE VISITORS: The Tourism Administration said that it is seeing positive prospects in its efforts to expand the tourism market in North America and Europe Taiwan has been ranked as the cheapest place in the world to travel to this year, based on a list recommended by NerdWallet. The San Francisco-based personal finance company said that Taiwan topped the list of 16 nations it chose for budget travelers because US tourists do not need visas and travelers can easily have a good meal for less than US$10. A bus ride in Taipei costs just under US$0.50, while subway rides start at US$0.60, the firm said, adding that public transportation in Taiwan is easy to navigate. The firm also called Taiwan a “food lover’s paradise,” citing inexpensive breakfast stalls
TRADE: A mandatory declaration of origin for manufactured goods bound for the US is to take effect on May 7 to block China from exploiting Taiwan’s trade channels All products manufactured in Taiwan and exported to the US must include a signed declaration of origin starting on May 7, the Bureau of Foreign Trade announced yesterday. US President Donald Trump on April 2 imposed a 32 percent tariff on imports from Taiwan, but one week later announced a 90-day pause on its implementation. However, a universal 10 percent tariff was immediately applied to most imports from around the world. On April 12, the Trump administration further exempted computers, smartphones and semiconductors from the new tariffs. In response, President William Lai’s (賴清德) administration has introduced a series of countermeasures to support affected
CROSS-STRAIT: The vast majority of Taiwanese support maintaining the ‘status quo,’ while concern is rising about Beijing’s influence operations More than eight out of 10 Taiwanese reject Beijing’s “one country, two systems” framework for cross-strait relations, according to a survey released by the Mainland Affairs Council (MAC) on Thursday. The MAC’s latest quarterly survey found that 84.4 percent of respondents opposed Beijing’s “one country, two systems” formula for handling cross-strait relations — a figure consistent with past polling. Over the past three years, opposition to the framework has remained high, ranging from a low of 83.6 percent in April 2023 to a peak of 89.6 percent in April last year. In the most recent poll, 82.5 percent also rejected China’s
PLUGGING HOLES: The amendments would bring the legislation in line with systems found in other countries such as Japan and the US, Legislator Chen Kuan-ting said Democratic Progressive Party (DPP) Legislator Chen Kuan-ting (陳冠廷) has proposed amending national security legislation amid a spate of espionage cases. Potential gaps in security vetting procedures for personnel with access to sensitive information prompted him to propose the amendments, which would introduce changes to Article 14 of the Classified National Security Information Protection Act (國家機密保護法), Chen said yesterday. The proposal, which aims to enhance interagency vetting procedures and reduce the risk of classified information leaks, would establish a comprehensive security clearance system in Taiwan, he said. The amendment would require character and loyalty checks for civil servants and intelligence personnel prior to
