In science we attempt to classify everything. And everything seems to be a subset of something else. Planet is a part of a solar system, solar system is a part of a galaxy, galaxy is part of the universe, universe is a part of our dimension, etc.
Obviously there are exceptions to this, rogue planets, but we still consider them contained.
I understand the idea of multidimensions is theoretical, but if they exist, do we have a name or even a theory what might contain them?

Not familiar with this concept of dimension tbh. I think that when one talks about something bigger than the Universe, they have a specific theory in mind, with its specific definition of what the universe is. Which theory do you take this notion of dimension from?
They are using the scifi-concept of dimension which has nothing to do with the mathematical or physical concept of dimension.
@PinkOwls
I thought “dimension” in scifi was meant as “universe”, like a parallel dimension is a parallel universe. What is the difference between the two?
