Neutrinos could reveal fundamental truths of the universe.

When we look at the evolution of the universe, it starts off as this ball of energy with equal amounts of matter and antimatter, and that had to evolve into a universe now which is dominated by matter.

And we know this because we look out in the universe and we can see that it's made of matter.

There's very little antimatter remaining.

We don't understand how that occurred.

We have theories.And it turns out the neutrino might be the key to that mystery of how the universe evolved from a bunch of energy into a matter-dominated universe.

If we didn't have that happen, we wouldn't be here.

Photodetectors and charge sensors inside the time projection chamber pick up that signature.
