I'm sure you must have, as I have, wondered how many stars there are in the sky. I sort of knew it was a lot, but according to Australian astronomers, there are 70,000,000,000,000,000,000,000 in the known universe (that's seventy sextillions). Apparently, this is ten times more than the number of grains of sand in all the earth's beaches and deserts.
And even then, the British astronomer and physicist, Sir James Jeans reckons that if you "empty Waterloo Station of everything except 6 specks of dust, it will be far more crowded with dust than space is with stars." It does make one feel small in the wider scale of things.
