1.4 km laboratory testing under Italian rock to solar neutrinos

According to the American “Science Weekly” reported that the Italian National Institute of Nuclear Physics is located 1.4 km under the rock (INFN) Gran Sasso National Laboratory (LNGS) running Borexino experiment to detect solar neutrinos.

Scientists have long believed that the sun’s energy to a large extent from the proton nuclear reaction process polyethylene into helium, and now they can finally use powerful experimental results show that this view. An international research team used deep in the mountains, the mountains of central Italy detectors measured, the first part of a chain reaction inside the sun, the proton – proton fusion reaction, can spray a low energy neutrinos, this process provides solar energy 99%. The experimental results have been published in “Nature” magazine.

The results also indicate that the sun is a very stable source of energy. Neutrinos reaching the Earth from the sun’s core just eight minutes, so the research team measured neutrino productivity reflects the heat generated by the sun that day. And 100,000 years ago, the residual energy of the photon fusion also happens to correspond to the residual energy of the day the sun nuclear fusion, even though this part of the ability to use the 10 years it turned into photons reaching the Earth from the sun’s core. So this 10 years ago, the sun’s production capacity has not changed. “This is a direct proof of the stability of the sun in the past 10 million years, the” members of the team from the University of Massachusetts, Amherst Andrea Pocar said.

The lab is located 1.4 km under the Italian Apennines rock, this low-energy solar neutrino laboratory detector includes a by 1000 tons of ultrapure water as a shield around the ball around. The ball through the body with 300 tons of liquid hydrocarbons like benzene purification. When neutrinos have been hit, the liquid surface will issue a tiny spark.

Study of the project for a long time, back in 2012, there broke the news that the Italian Gran Sasso National Laboratory found that superluminal neutrinos, then, CERN, one of the partners in this research project, said the release bulletin there are two problems neutrino velocity measurement methods previously used, it may lead to the deviation measurement results, there is no object at any speed can exceed the speed of light.
