Incase you dont understand, I think I heard before that out of all things a bubble is a perfect shape and more perfect then any other shape on earth. I guess symmetry wise. Has anyone herd this or know the asnwer?

and im talking about just a bubble, nothing else that is shaped as a sphere. the bubble is supposably perfect compared to all other shapes. including other sphere's

You mean sphere. A bubble is actually quite flexible. A soap bubble It will sag under its own weigh and wobble in the slightest breeze. Maybe in space is a closed container it would be the closest *naturally formed* sphere, but nothing is perfect. If nothing else, there will be thermal vibrations and lumpy molecules on a microscopic scale.

A bubble can be very much like a sphere. But a perfect sphere is impossible to attain.
In gravity for example, the bubble will be thicker towards the bottom because of the downward pull. And in the absence of gravity, there is some gas in the bubble - and realistically, it is impossible for the gas within any closed volume to be PERFECTLY uniform. Of course we would approximate it that way. But at the molecular level, perfect uniformity is not possible. Therefore, there will be slight deformations that make it not spherically symmetric.

Liquids have something called surface tension. This means that a gas-liquid interface will pull in every direction like an inflated balloon. Associated with this is a form of elastic potential energy proportional to the surface area of the interface. Dynamical systems in general will adjust all there degrees of freedom spontaneously so as to minimize their potential energy. That's why a ball will roll to the bottom of a hill, for example. The minimum energy of a bubble is the shape with minimum surface area, then. A fixed volume with the smallest surface area possible is a sphere.

A sphere (bubble) is a "perfect" shape in the sense that it's a minimal shape. That is, it minimizes surface area per unit volume.

It can not be perfect. Too many forces against it like are against anything in the universe. Most of which is unmeasurable.
