A single neutrino with incredible energy, caught in the depths of the ocean, might have been born when the Universe was just 380,000 years old. It's not just a particle, but a message from the era when the first atoms were forming. It forces us to rethink how ghostly particles were accelerated at the very beginning of the world.

🎯 Every second, trillions of solar neutrinos pass through your body without causing the slightest harm.

🎬 Like in Arthur C. Clarke's 'Space Odyssey', where a mysterious signal comes from an unimaginable past.
