More Stars in Universe than Sand on Beaches Explained

I’ve often heard that there are more stars in our universe than there are grains of sand on all Earth’s beaches, but still find it mind-boggling. I’m glad to say Fraser Cain agrees it’s difficult to imagine, before explaining it well with maths, and getting in some great greenYgreying at the same time, in this universetoday.com video:

It’s still difficult to imagine our star in the universe, amongst the billions of others, so in the upcoming XaW Files book I hypothesise our galaxy is probably like a speck of dust made visible by sunlight floating aimlessly in a room, which I find helps me imagine the possible approximate scale.
