# Dimensional knots?

Hey all, i don't know if this is the right forum for this but i think there is a branch of math that studies knot and i just have few questions.
Today i was untying a knot and then i though, maybe it would be easier to untie a 3D knot in a 4D world (not time). Am i right? Since nobody can visualize a 4D dimention, so i simplified to 2D knot in 3D, then i realize you cannot have a knot in 2D, the string has to cross itself(entering 3D) at least once to become a knot.
Then further, how much a higher dimention knot look or act like in a lower dimention, or does that not even apply? Anyway just few questions that bugged me the whole day, thanks for reading!

The branch of mathematics you're thinking of is Topology, or, more specifically a subfield of Topology called Knot Theory. And, I think, the dimensonality your thinking of isn't what the mathematicians are thinking of. I won't say any more, as I earned a C+ in topology. I'll leave it to my colleagues.
