Jakarta, CNNIndonesia —

Physicist Stephen Hawking once asked his colleagues to make Black hole or Black Hole on Earth. Could it come true?

This was revealed in Hawking’s dialogue with Thomas Hertog who is also a professor of theoretical physics at the University of Leuven. He is also a writer On The Origin of Time Stephen Hawking’s Final Theory.

Hertog in his writings at Space revealed Hawking’s wish was expressed during a visit to the Large Hadron Collider.

“When Stephen Hawking and I visited the Large Hadron Collider, he hoped for an unexpected physics breakthrough. His dream just might come true,” wrote Hertog.

“‘I hope, you make a black hole’, Hawking said with a broad smile,” he wrote, imitating the words of the late.

Higgs Bosons

Hertog told that he and Hawking visited the CERN laboratory, the legendary European Organization for Nuclear Research near Geneva, Switzerland. During their visit, the two men had to take a freight elevator to the ATLAS experimental room.

“It was 2009, and someone had filed a lawsuit in the United States, concerned that the Large Hadron Collider, LHC, newly built by CERN, would produce a black hole or some other form of exotic matter that could destroy Earth,” recalls Hertog.

The LHC, which is being built under the Swiss-French border tunnel, is a ring-shaped particle accelerator built principally to create the Higgs bosons.

At that time, the Higgs bosons were the missing piece in the Standard Model of particle physics.

The LHC’s circumference is 27 kilometers (nearly 17 miles). This facility could accelerate protons and antiprotons in a counter-rotating beam in a circular vacuum tube to 99.9999991 percent the speed of light.

At three locations along the ring, accelerated particle beams can be directed for highly energetic collisions.

The emission recreated conditions comparable to those prevailing in the universe a fraction of a second after the hot big bang, when the temperature was over a million billion degrees.

“The trail of the particle jets created in these violent head-on collisions is picked up by millions of sensors that stack like mini-Lego blocks to create giant detectors, including the ATLAS detector and the Compact Muon Solenoid, or CMS,” Hertog wrote.

The LHC was successfully turned on in November 2009. As a result, the ATLAS and CMS detectors detected traces of the Higgs bosons in the debris of the particle collisions.

The LHC does not create black holes to this day. However, Hawking actually hopes that maybe it can come true.

Hertog said there had been limited perception of black holes as the remnants of massive stellar impacts.

“However, anything can actually become a black hole if we squeeze it down to a very small volume,” wrote Hertog.

“Even a proton-antiproton pair accelerated to near the speed of light and squished together in a powerful particle accelerator will form a black hole if the collision concentrates enough energy into a small enough volume,” he said.
