A large-scale experiment has been taking place in Antarctica to solve one of the greatest enigmas in physics: the existence of quantum gravity.
A large-scale experiment in Antarctica may solve one of the greatest enigmas in physics: the existence of quantum gravity.
It consists of thousands of sensors covering vast areas to detect and monitor neutrinos — the ghostly particles reaching Earth from outer space.“The unification of quantum theory and gravitation remains one of the most outstanding challenges in fundamental physics. It would be very satisfying if we could contribute to that end,” said Tom Stuttard, assistant professor at Niels Bohr Institute .
“Looking at neutrinos originating from the Earth’s atmosphere has the practical advantage that they are by far more common than their siblings from outer space. We needed data from many neutrinos to validate our methodology. This has been accomplished now. Thus, we are ready to enter the next phase in which we will study neutrinos from deep space,” added Stuttard.Neutrinos are unaffected by electromagnetic forces or by strong nuclear forces.
As per the press release, a neutrino is not a single particle in the usual sense, but rather a combination of three distinct particles that are produced together.
