It could be the beginning of Neutrino astronomy [1]. So far, we only used the electromagnetic spectrum, from radio waves to gamma rays, to observe the universe. If we could equally leverage neutrinos or gravitational waves, we could observe much more of the universe. For example, the cosmic microwave background radiation enables us to deduce the conditions at 300ky after the Big Bang. The cosmic neutrino background [2] could give us insight in the conditions 1s after the Big Bang.

Knowing the properties of neutrinos is essential for building the neutrino bomb, the most ethical weapon possible.

Neutrino detectors are essential in receiving communication from other galaxies.
