SvenskaIgår, den 23 september publicerade BBC News en ny upptäckt av forskare från CERN i Schweiz som ger mig hopp om att en ny syn på materia och följaktligen hela den allmänt accepterade världsbilden håller på att ge vika. Jag känner stor glädje idag även om jag vet att forskarnas upptäckter fortfarande är nya och inte helt förstådda. Dock just det faktum att någon, om än försiktigt, kan tänka sig att den absoluta begränsning Einstein och andra låst vår världsbild i kan vara felaktig ger hopp om en större förståelse för fenomen tidigare avfärdade som fantasier och vidskepelse och känslopjunk.

A meeting at Cern, the world’s largest physics lab, has addressed results that suggest subatomic particles have gone faster than the speed of light.
The team presented its work so other scientists can determine if the approach contains any mistakes. If it does not, one of the pillars of modern science will come tumbling down.
Antonio Ereditato added ”words of caution” to his Cern presentation because of the ”potentially great impact on physics” of the result.
The speed of light is widely held to be the Universe’s ultimate speed limit, and much of modern physics – as laid out in part by Albert Einstein in his theory of special relativity – depends on the idea that nothing can exceed it. “
We want to be helped by the community in understanding our crazy result – because it is crazy” Antonio EreditatoAntonio Ereditato
Thousands of experiments have been undertaken to measure it ever more precisely, and no result has ever spotted a particle breaking the limit.
”We tried to find all possible explanations for this,” the report’s author Antonio Ereditato of the Opera collaboration told BBC News on Thursday evening.
”We wanted to find a mistake – trivial mistakes, more complicated mistakes, or nasty effects – and we didn’t. ”When you don’t find anything, then you say ‘well, now I’m forced to go out and ask the community to scrutinise this’.”
Friday’s meeting was designed to begin this process, with hopes that other scientists will find inconsistencies in the measurements and, hopefully, repeat the experiment elsewhere.
”Despite the large [statistical] significance of this measurement that you have seen and the stability of the analysis, since it has a potentially great impact on physics, this motivates the continuation of our studies in order to find still-unknown systematic effects,” Dr Ereditato told the meeting. ”We look forward to independent measurement from other experiments.”
Neutrinos come in a number of types, and have recently been seen to switch spontaneously from one type to another.
The Cern team prepares a beam of just one type, muon neutrinos, and sends them through the Earth to an underground laboratory at Gran Sasso in Italy to see how many show up as a different type, tau neutrinos.
In the course of doing the experiments, the researchers noticed that the particles showed up 60 billionths of a second earlier than they would have done if they had travelled at the speed of light.
