Scientific Problems of Neutrino Astronomy
- Solar neutrino problem - In detecting solar neutrinos, it became clear that the number detected was half or a third than that predicted by models of the solar interior. The problem was solved by revising the properties of neutrinos and understanding the limits of the detection mechanisms - only one third of the forms of neutrinos coming in was being detected and all neutrinos oscillate between the three forms.
- Cosmic neutrino background - (CNB) is the background particle radiation composed of neutrinos as a relic of the big bang which decoupled from matter when the universe was 2 seconds old.
- Hot dark matter - since many neutrinos come from stellar cores and supernovae, they are released at great temperature/energy. As neutrinos do not interact with matter electromagnetically, they are by definition dark matter.
- Warm dark matter - possibly so called sterile neutrinos.

Famous quotes containing the words scientific problems, scientific, problems and/or astronomy:
“All problems are finally scientific problems.”
—George Bernard Shaw (1856–1950)
“Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.”
—Oscar Wilde (1854–1900)
“I rarely speak about God. To God, yes. I protest against Him. I shout at Him. But to open a discourse about the qualities of God, about the problems that God imposes, theodicy, no. And yet He is there, in silence, in filigree.”
—Elie Wiesel (b. 1928)
“It is noticed, that the consideration of the great periods and spaces of astronomy induces a dignity of mind, and an indifference to death.”
—Ralph Waldo Emerson (1803–1882)
