PARTICLES TRAVEL FASTER THAN LIGHT – Scientists

Ho, hum! For you, physicists and the like, the following information may seem unbelievable, whereas for me, it is what I had stated in my books all along.

ALREADY THERE IS A GROWING BODY OF SCIENTIFIC EVIDENCE TO ONE OF VICTOR'S REVELATIONS: That a physical body moving in vacuum space is not restricted to the so-called 'speed of light'.

Particles travel faster than light, say scientists

Physicists have reported that sub-atomic particles called neutrinos can travel faster than light, a finding that, if verified, would blast a hole in Einstein's theory of relativity.

In experiments conducted between the European Centre for Nuclear Research (CERN) in Switzerland and a laboratory in Italy, the tiny particles were clocked at 300,006 kilometres per second, about six kps faster than the speed of light, the researchers said.

"This result comes as a complete surprise," said physicist Antonio Ereditato, spokesman for the experiment, known as OPERA. "We wanted to measure the speed of neutrinos, but we didn't expect to find anything special."

Scientists spent nearly six months "checking, testing, controlling and rechecking everything" before making an announcement, he said.

Researchers involved in the experiments were cautious in describing its implications, and called on physicists around the world to scrutinise their data.

But the findings, they said, could potentially reshape our understanding of the physical world.

"If this measurement is confirmed, it might change our view of physics," CERN research director Sergio Bertolucci said.

The view was echoed by several independent physicists.

In the experiments, scientists blasted a beam producing billions upon billions of neutrinos from CERN, which straddles the French-Swiss border near Geneva, to the Gran Sasso Laboratory 730 kilometres away in Italy.

Neutrinos are electrically neutral particles so small that only recently were they found to have mass.

"The neutrinos arrived 60 nanoseconds earlier than the 2.3 milliseconds taken by light," Professor Ereditato said.

Under Albert Einstein's theory of special relativity a physical object cannot travel faster than the speed of light in a vacuum.

The fact that the neutrinos were moving through matter - including a slice of Earth's crust - could not have caused them to accelerate, said French physicist Pierre Binetruy, who was not involved in the experiment but has reviewed the data.

"It might have slowed them down, but it certainly didn't make them go faster than the speed of light," he told French journalists.

He described the results as "altogether revolutionary," and said they will, if backed up, force physicists to go back to the blackboard.

"The theory of general relativity, the theory of special relativity - both are called into question," he said.

Alfons Weber, a neutrino expert who participated in a similar experiment in 2007 at the US Fermilab, agreed that the faster-than-light neutrinos could not be reconciled with current theories, but said the results needed to be duplicated elsewhere.

"There is still the possibility of a measurement error," he said by phone. "It would be too exciting to be true. That's why I'm cautious."

The earlier test, conducted over the same distance, also gave a slight edge to neutrinos in the race against light, but the results were within the experiment's margin of error, said Dr Weber, a reader in particle physics at Oxford University.

The CERN announcement was likely to prompt another round of more accurate tests in the US, he added.

Even if verified, however, the new findings would not entirely invalidate Einstein's brilliant insights, which has held sway for more than a century.

"The theory of special relativity will still be a good theory if you apply it where it is valid, but there will have to be some extensions or modifications," he said.

Newton's theory of gravity, he noted, still explains the movement of planets well enough to send missions into space, even if Einstein's theories proved it was not quite correct.
