In the naive set theory of the nineteenth century, the term universal set referred to the set of all sets. If one was doing set theory with objects that were not sets (these are sometimes called urelements), those were included in the universal set as well. However, Bertrand Russell and others discovered that this concept leads to paradoxes, such as the set of all sets not members of themselves (the universal set being a member of itself), which is a member of itself if it is not, and not a member of itself if it is. So axiomatic set theories were developed to hopefully avoid these paradoxes. It was also discovered that urelements are not necessary to do set theory that can be used as the basis of all areas of mathematics.
In a more limited context, the term universal set or universe of discourse is used to refer to the set of things being discussed and studied. For example, in the area of the mathematical study of integers (positive and negative whole numbers), the set of all integers is the universe of discourse. This seems to be harmless in that it does not lead to paradoxes, as far as is known.
It is the set of "everything".

In mathematics, specifically in set theory, the term "B complement" refers to the elements that are not in set B but are in a universal set U. It is denoted as ( B' ) or ( U - B ). This concept helps to define the difference between the universal set and a given subset, allowing for operations like union and intersection to be performed more easily. Essentially, B complement includes all the elements of the universal set that do not belong to set B.
Math is a universal language. It is performed the same everywhere.
An empty set in math is called a null set.
It is the set of "everything".
The universal set is the set containing each and every element under consideration.

"Universe" and "universal set" are two unrelated concepts.
An empty set in math is called a null set.
The universal set is the set of all possible elements under consideration. You can have a universal set of all people, or all bird species, or all numbers or whatever. You can even have a universal set of all people and all bird species and all numbers as one big set.
If the universal set contains N elements then it has 2N subsets.
Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.
No. Math is relative to you, your location and frame of reference. Our math is limited to what we understand and can compute. Math is greater than what we know, or can know.
A universal set in mathematics is a set that contains all the objects or elements under consideration for a particular discussion or problem. It is often denoted by the symbol ( U ) and can include various subsets. The concept helps in simplifying discussions about relationships between sets, such as unions, intersections, and complements. Essentially, it serves as a comprehensive backdrop against which other sets are defined.
