Right-handed neutrinos from a micro-dimension leave sharp steps in electron energy — and the KATRIN experiment is ready to catch them.

In tiny folds of space, invisible neutrinos may be hiding. Each such neutrino gives birth to a whole family of heavier doppelgangers. The KATRIN experiment can spot them by sharp kinks in electron energy. If the signal is found, it will become a window into an extra dimension.

🎯 A micron is a thousandth of a millimeter. That's about the size of a bacterium or the thickness of a spider's silk.

🎬 The idea of hidden dimensions has inspired science fiction: in the novel Flatland, two-dimensional inhabitants are unaware of the third until they see a visitor from the three-dimensional world.
