Neutrinos from the early universe have never been discovered directly, but a device that uses atom-thick graphene may be able to change that.

A particle detector made of extremely thin sheets of carbon may be able to detect never-before-seen neutrinos from the time of the Big Bang. If design works, discovering these so-called ultra-low-energy neutrinos can help us better understand the first moments of the universe.
Detecting all kinds of neutrinos is a challenge because they usually move through matter without affecting it – trillions of them are passing through you right now. They are one of the most common particles, but they are almost …
