It’s a different part of the universe, separate from normal space where things like baryonic matter exists. In subspace certain of our universe’s fundamental rules as seen in normal space don’t apply or constants are different.
How much of this is based on reality and how much is based on Star Trek wanting a mechanism to be able to communicate between star fleet and the Enterprise?
I think entirely Star Trek on this one. Although, if we ever want to move* faster than light, it’ll almost certainly require a science or an understanding of nature which we don’t even have theoretical concepts of in 2023.
