Our universe is not a very diverse place when it comes to shapes. Large celestial bodies become spheres, galaxies become discs, and there is little room for variation. Why is this? Well it turns out physics has some pretty strict rules when it comes to creating new planetary bodies. On this week's Space Time, we explore equillibrium and symmetry, the two defining factors that shape our universe.
