The Cosmic Neutrino Background

TL;DR

This paper discusses the cosmic neutrino background, its similarities to the cosmic microwave background, and the potential scientific importance of detecting this elusive neutrino relic from the early universe.

Contribution

It highlights the significance of the cosmic neutrino background and explores the challenges and potential methods for its detection, emphasizing its scientific value.

Findings

The CNB is analogous to the CMB but consists of neutrinos.

Detecting the CNB remains extremely challenging with current technology.

Successful detection could provide new insights into early universe conditions.

Abstract

The cosmic neutrino background is like the cosmic microwave background, but less photon-y and more neutrino-ey. The CNB is also less talked about than the CMB, mostly because it's nearly impossible to detect directly. But if it could be detected, it would be interesting in several ways that are discussed.
