The scale of the universe stretches from the Planck length, the smallest scale physics can describe, to the observable universe, the largest thing we can see.
Travel inward from one and outward from the other by powers of ten and they meet at something astonishingly familiar: the size of a human egg cell.
Michael Stevens (VSauce) takes Professor Hannah Fry on a journey through powers of ten, from quarks and protons and DNA to bananas and pyramids and on to planets and galaxies, to explore where we sit in the scale of the universe.
Along the way they ask whether the Planck length could be the universe's smallest pixel, whether reality might be a computer simulation and just how empty space really is.
Plus, your questions: why our best ideas arrive in the shower, Wikipedia's strangest rabbit holes and Hannah corrects the record on whether Saint Augustine and Thomas Aquinas believed curiosity was a sin.
