what is more important, time or space in defining the universe

This is a good question, but is largely answered in prior blogs.
The only thing that really matters is time because space is an illusion in this theory.
While there is much to be said for space as a practical necessity with or without time, there is no justification for this position.
I imagine the universe as coming from a singularity drop into a sea of time and burning into space more than I can see all that space somehow existing without time.
Perhaps this will be the explanation.  Instead of their being a place full of space, there is a space full of time.  There is no space as we know it, only time as we experience it.
Somehow, without space, into this sea of awareness the singularity is dropped and begins to dissolve; expanding into the universe we experience.
