Are substances something beyond properties?

Question

or are objects properties all the way down?

Another way to ask this is: is there any'thing' in addition to properties that unifies them, provides a structure, and is necessary for their existence?

Answer 1

any object that exists must exist in at least 4 of the 6 dimensions. that is sort of an environmental requirement. the object has to be somewhere and sometime. if its nowhere or doesnt last any time at all, existing is very difficult and requires certain laws of physics to be overridden.
