6. Neutrinos
Neutrinos are virtually mass-less and electrically neutral elementary particles that can pass through miles of solid objects unhindered. These “mystery” particles are created in the core of a huge, healthy star as well as a supernova explosion. Neutrino detectors placed beneath the sea and embedded deep underground solidly prove its existence. For every square centimeter of our body, 65 billion neutrinos pass every second and luckily, they don’t interact with other matter.
