I recall an animation/interactive thingy where you could go from the whole universe down to quarks by changin the order of magnitude step by step. Along the way you could see how big a galaxy is compared to the solar system, the solar system compared to the planets, the earth compared to big ben, and so on and so forth.
My google-fu is failing me, so I’m hoping someone remembers the same animation and actually has a link. Or more powerful google-fu.
