120 PeV. That's about 1/1000th of a Joule.

For reference, an 80mph fastball is ~93J.

So, a particle with so little mass that it was long thought they had none at all, had so much energy that it's approaching the energy regime of non-quantum object that will HURT you.

You might have heard about the detection of an incredibly high energy cosmic neutrino by an amazing, underwater experiment 🔬 🌊

I covered @km3net.bsky.social last time they broke the neutrino energy record!

Check it out and know what all the fuss is about!
