While you cannot form the unknot in three dimensions by adding two non-trivial knots, you can in higher dimensions, at least when one considers smooth knots in codimension at least 3. Knots can also be constructed using the circuit topology approach.

Knot theory is a branch of topology that studies the mathematical properties of knots and their higher-dimensional analogues. It involves understanding the ways in which knots can be manipulated and transformed without cutting or gluing their strands.
Knot theory is closely related to the study of higher dimensions because it involves understanding the behavior of knots in spaces with more than three dimensions. This allows for a deeper understanding of the structure and complexity of knots.
Some real-world applications of Knot Theory include DNA research, understanding molecular structures, and studying fluid dynamics. Knot theory can also be applied in the fields of physics, chemistry, and computer science.
The main tools used in Knot Theory include group theory, algebraic topology, and differential geometry. These branches of mathematics help to analyze and classify knots and their properties.
There are many open problems in Knot Theory and higher dimensions, including the classification of all possible knots, understanding their symmetries and invariants, and finding efficient algorithms for knot recognition. Additionally, there is ongoing research on the connections between Knot Theory and other fields of mathematics, such as quantum t...
To address your original question, that surfaces in 4-space can still intersect and that they can be knotted may not effect the potential knottedness in dimension 5. On the other hand, it is easy to construct knottings of 3-manifolds in 5-space by spinning and twist-spinning.
Feb 9, 2011 · In higher dimensions - 4 or more - two loops can not be linked. They can always be separated. Also any knot can be unknotted.
Apr 28, 2021 · Though your intention with knots in real life is usually to be able to untie them at some point, mathematical knots cannot be untied; unless the knot is equivalent to the simplest knot—a closed loop—it will still have tangles and crossings even if you twist it and bend it into its "most untied" form.
Apr 6, 2022 · But knots have special significance in math and science because their properties can help unlock secrets hidden within topics ranging as widely as the biochemistry of DNA, the synthesis of new materials and the geometry of three-dimensional spaces.

Apr 24, 2021 · In higher dimensions (well, higher than 3) we avoid polygonal knots and consider instead “smooth knots.” Definition. The k-sphere Sk is the set of unit vectors in Rk+1: Sk = {(x 1,x 2,...,x k+1) ∈ Rk+1 | x2 1 +x 2 2 +···+x1 k+1 = 1}. Note. We take this opportunity to briefly complain about he distinction between vectors in Rn and ...
