Sterile neutrinos and seesaws

Time and again, the study of neutrinos has confounded scientists. One very peculiar property of neutrinos is that only neutrinos with a specific spin configuration have been observed. In this video, Fermilab’s Dr. Don Lincoln talks about this and lays out the possibility that other types of neutrinos might exist, called right handed or sterile neutrinos. To demonstrate this key point, he even includes some video clips in which children are in mortal danger.
