A perfect circle can exist, but only in theory. Much the same way there is an infinite set of points in a line, as you move outward from the centerpoint of a circle, there exists an infinite number of points which can exist in any real circular body. In any case, there is no way to measure the exactness of a circle so that it could be 100% accurate without some other measure of the same distance being MORE accurate.

But of course! Back in high school I had a geometry teacher Brad Johansen who used to go up to the blackboard when explaining a process or theorem and invert his arm upside down (hand down at the bottom with the chalk in it) and quickly swing it around in a full and complete arc making a perfect circle everytime. It was so uncanny and so amazingly perfect each time the class spontaneously broke out into a polite round of applause everytime he created one of his arm-swing arc-circles. It was really phenomenally precise. He must have drawn a lot of them. To see him do it, well, it was over before it began. That is how fast he would make the complete swing of his arm.

Nothing in this universe is "perfect" . However, if you want to base your question on rational generalities, sure..... a "perfect" circle exists . To explain further..... if you were to look at the edge of the circle under magnification you would find at some strength of magnification that the line is not perfectly even. Therefore , the circle is not perfect. But, why would you want to look at it that closely?

well the only thing small enough to be an exactly perfect circle is a quark or an electron. its possible that they are perfect circles. but its is impossible for anything else to be an exactly perfect circle since its made of atoms which are tiny tiny spheres, so anything that looks like a perfect circle would really have ultra microscopic bumps in it.

I once dated a girl that had a perfect ring ,sorry circle.

It's entirely impossible. It could only appear perfect to the human eye.

No mathematically perfect geometric shape exists in physical reality.

Do you mean Naturally? Or do you mean can one be created? I'm not sure I understand what you question is but yes they do exist.

Yes, they're a pretty good band with Manyard James Keenan from Tool. ;-) Sorry, I had to.
But to actually answer the question, I don't know.

some subatomic particles, possibly, but you get into all sorts of quantum physics wave versus particle questions.
