Solar neutrinos are able to provide direct insight into the core of the Sun because that is where the solar neutrinos originate. [1] Solar neutrinos leaving the Sun's core reach Earth before light does due to the fact solar neutrinos do not interact with any other particle or subatomic particle during their path, while light ( photons ) bounces ...
However, in 1968 Pontecorvo proposed that if neutrinos had mass, then they could change from one flavor to another. [8] Thus, the "missing" solar neutrinos could be electron neutrinos which changed into other flavors along the way to Earth, rendering them invisible to the detectors in the Homestake Mine and contemporary neutrino observatories.
After Bahcall calculated the rate at which the detector should capture neutrinos, Davis's experiment turned up only one third of this figure. The experiment was the first to successfully detect and count solar neutrinos, and the discrepancy in results created the solar neutrino problem. The experiment operated continuously from 1970 until 1994.
A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.

The operation, also known as the Davis experiment, allowed Raymond Davis, Jr. to measure the flux of solar neutrinos directly. [15] The measurements' discrepancy with the flux predicted from the Sun's luminosity led to Davis's development of the solar neutrino problem. The Homestake experiment publicized the mine as a resource among scientific ...

The rate of neutrinos detected by this experiment disagreed with standard solar model predictions. Thanks to the use of gallium, it was the first experiment to observe solar initial pp neutrinos. Another important result was the detection of a smaller number of neutrinos than the standard model predicted (the solar neutrino problem). After ...
