Disclaimer : please avoid comments like “You forgot [some object]“ , it isn't an exhaustive video , it's impossible for me to include all possible objects. I choose the most interesting objects in my opinion. The complex stuff like buildings , animals , human … are not mine , I’ve picked up some models on Sketchup 3D Warehouse. I have modelised myself small stuff (atoms , virus , cells … ) and spatial stuff (asteroids , planets , stars …) Chapters: 0:00 Intro 0:16 Subatomic particles 2:14 Atoms and molecules 3:06 Viruses 3:44 Bacterias and cells 5:02 Human scale (animals , objects , vehicles , buildings ...) 8:32 Small moons , pulsars and small black holes 9:42 Big moons , countries and dwarf planets 11:05 Planets and small stars 12:42 Stars 14:18 Nebulas 15:07 Galaxies 15:47 Clusters of galaxies 16:14 Obse
