Ancient Subatomic Signature Discovered Spanning the Universe
An ancient subatomic signature extends across the universe. It seems that some subatomic particles, invisible and untouchable effects of the very creation of reality, might exist simultaneously across all of space.
"Relic" neutrinos, like the relic photons that make up the cosmic microwave background, are leftovers from the hot, dense early universe that prevailed 13.7 billion years ago. But over the lifetime of the cosmos, these relic neutrinos have been stretched out by the expansion of the universe, enlarging the range in which each neutrino can exist.
