In search of no neutrinos
G. Gratta, N. Kurahashi · Physics World · 2010
As you sit down to relax and read this article, take a moment to consider that more than 10 million neutrinos created in the Big Bang are traversing your body at any one time. These tiny subatomic particles have been travelling across the universe for the last 13 billion years, carrying the fingerprints of the primordial cosmic explosion. As they course through your body they will ignore it, because – challengingly for anyone wishing to study these particles experimentally – the probability of neutrinos interacting with matter is so minute that they can cross entire planets or stars without being disturbed.
