A billiard ball clicks against another in complete darkness. The sound of the impact and the clatter of balls dropping into pockets: that's all you hear. This is roughly how physicists study the interactions of elementary particles at energies that no terrestrial accelerator can reproduce.

Measuring distances in the universe is no easy task. Almost all methods rely on light, which can be absorbed by dust, scattered, or distorted along the way. It's like trying to spot a distant lighthouse through fog and haze. Neutrinos are a different story. These ghostly particles pass through anything without noticing obstacles.

Imagine an interpreter at a meeting where everyone speaks a language they don't know. At first, they have to listen to every word, write it down verbatim, and then check against the original. That's how simulations for the IceCube neutrino telescope work: they track every photon born in the Antarctic ice, traveling hundreds of meters to hit a sensor.
