The February 21, 2019 issue of the Live Science "livescience.com" published an article entitled "What Are Neutrinos?" written by Adam Mann (Live Science Contributor).
The author writes, "Neutrinos are elusive subatomic particles created in a wide variety of nuclear processes."
"Their name," notes the writer, "which means "little neutral one," refers to the fact that they carry no electrical charge."

Adam Mann who is the Live Science contributor explains, "Of the four fundamental forces in the universe, neutrinos only interact with two — gravity and the weak force, which is responsible for the radioactive decay of atoms."
"Having nearly no mass," he writes, "they zip through the cosmos at almost the speed of light."
The writer goes on to address, "Countless neutrinos came into existence fractions of a second after the Big Bang."
He writes, "And new neutrinos are created all the time: in the nuclear hearts of stars, in particle accelerators and atomic reactors on Earth, during the explosive collapse of supernovas and when radioactive elements decay."
"This means that there are, on average,
1 billion times more neutrinos than protons in the universe, according to physicist Karsten Heeger of Yale University in New Haven, Connecticut," adds the author.

The Live Science contributor Adam Man writes, "Despite their ubiquity, neutrinos largely remain a mystery to physicists because the particles are so tough to catch."
He explains, "Neutrinos stream through most matter as if they were light rays going through a transparent window, scarcely interacting with everything else in existence."

The author notes, "Approximately
100 billion neutrinos are passing through every square centimeter of your body at this moment, though you won't feel a thing." [

Adam Mann talks about "Discovering invisible particles" and writes:
"Neutrinos were first posited as the answer to a scientific enigma."
The author (the Live Science contributor) addresses, "In the late 19th century, researchers were puzzling over a phenomenon known as beta decay, in which the nucleus inside an atom spontaneously emits an electron."
"Beta decay," the author points out, "seemed to violate two fundamental physical laws: conservation of energy and conservation of momentum."

The writer explains, "In beta decay, the final configuration of particles seemed to have slightly too little energy, and the proton was standing still rather than being knocked in the opposite direction of the electron."
He notes, "It wasn't until 1930 that physicist Wolfgang Pauli proposed the idea that an extra particle might be flying out of the nucleus, carrying with it the missing energy and momentum."

Adam Mann, the Live Science contributor cites Pauli who said to a friend, referring to the fact that his hypothesized neutrino was so ghostly that it would barely interact with anything and would have little to no mass.
"I have done a terrible thing. I have postulated a particle that cannot be detected," Pauli said.

The author writes, "More than a quarter century later, physicists Clyde Cowan and Frederick Reines built a neutrino detector and placed it outside the nuclear reactor at the atomic Savannah River power plant in South Carolina."
"Their experiment managed to snag a few of the hundreds of trillions of neutrinos that were flying from the reactor, and Cowan and Reines proudly sent Pauli a telegram to inform him of their confirmation," adds the writer.
The author continues, "Reines would go on to win the Nobel Prize in Physics in 1995 — by which time, Cowan had died."
