Take a walk outside and you'll realise many things are round. Wheels are round, a cup is round and even that home button on your iPhone is round. But that's all man made.
In nature, there are many things that are round too! From the planets to our sun and even a sunflower or atom. They are all round. Well, they might not be a perfect circle but they all take that round, curved shape. The universe seems to take this circular approach to almost everything. This doesn't only include objects but concepts too, including orbits, spirals, and rotation.
From my experience, creating round things is often much easier than creating things with edges. For example, when building a snowball it is much easier to mould the snowball into a sphere than a cube. Could this be a reason to why the objects in our universe are so round.
Why is it that almost everything in the universe is based upon round things?
