In our current understanding of physics, space and time are indeed interconnected as a single entity called spacetime. Spacetime forms the framework within which all events occur, and it is influenced by the presence of matter and energy.
The concept of being "outside" of spacetime is not well-defined within our understanding of the universe. Since spacetime encompasses all of existence as we know it, it is challenging to conceive of something existing outside of it. The idea of being outside of spacetime implies a realm or domain that is not governed by the laws and properties that characterize our universe.
Speculating about what might exist outside of spacetime is largely a matter of philosophical or speculative inquiry. Some theories and ideas, such as the concept of a multiverse or higher-dimensional spaces, propose the existence of realms beyond our own spacetime. However, these ideas remain theoretical and lack empirical evidence.
It's worth noting that as our scientific understanding evolves, our conceptions of spacetime and the nature of existence may also change. However, at present, the notion of something existing outside of spacetime is not well-defined within the framework of modern physics.
