Can a perfect circle exist in nature?

They can occur naturally — in planets, stars, celestial bodies, tree rings, rain drops — or they can be man-made — such as traffic roundabouts, buttons, volleyballs, pizza.

Are perfect circles possible?

You cannot have perfect circles in reality. Neither can you have perfect lines or perfect triangles. This is not only because the world consists of molecules, but also because the universe is curved. So we will never be able to create a perfect Euclidean circle since our world is not Euclidean.

Do circles have sides?

If you think of the circle as a disk then it it has an up-side and a down-side. If you think of it as a curve, then it has an inside and an outside. If you think of it as the limit of an n-sided regular polygon, then one can justify the answer that the circle has infinitely many infinitesimal sides.

Are there any real circles in nature?

There are no “real” circles in nature. That is to say, an actual circle is an idea rather than a physical thing. According to Plato, the idea of a perfect circle is the Form of a circle,[1] which is to say, it’s a representation of a perfect circle.

Is it possible to build a perfect circle?

Human brain is nature, so yes perfect circle in nature is a go! Pi is a transcendental number. You can never build anything with a ratio of Circumference=2pi*r using a finite number of points. You can’t even square a circle using a finite number of operations*.

Do straight lines and perfect circles exist in reality?

Straight lines and perfect circles don’t exist in reality, all perfect shapes are mathematical abstractions. Straight lines and perfect circles don’t exist in reality; they are mathematical abstractions.

Is there such a thing as a perfectly smooth circle?

no. nothing comprised of atoms has a “perfectly smooth” circumference. even if you try to describe a perfect circle within spacetime without regard to any physical entity, you cannot acheive a perfect circle since spacetime is not perfectly smooth – it is limited to discrete fractions at the planck limit, ie the planck length.
