Draw a one centimetre square on your finger & hold it towards the Sun πŸ‘†

Now consider that some 60 billion neutrinos hit it every second, created by nuclear fusion in the solar core 500 seconds ago πŸ™€

Even if it’s nighttime & your finger has to point down through Earth’s surface – they don’t care πŸ™ƒ

But if it makes you feel better, there are only about 2 solar neutrinos in each cubic centimetre of you at any given instant πŸ€·β€β™‚οΈ

Well, plus another 300 from the Big Bang 😬
