Here is more from wikipedia on spacetime:
The term spacetime has taken on a generalized meaning beyond treating spacetime events with the normal 3+1 dimensions. It is really the combination of space and time. Other proposed spacetime theories include additional dimensions—normally spatial but there exist some speculative theories that include additional temporal dimensions and even some that include dimensions that are neither temporal nor spatial (e.g., superspace). How many dimensions are needed to describe the universe is still an open question. Speculative theories such as string theory predict 10 or 26 dimensions (with M-theory predicting 11 dimensions: 10 spatial and 1 temporal), but the existence of more than four dimensions would only appear to make a difference at the subatomic level.
Here is a clever commenter that chips in on this phenomenon:
It is nothing, and yet you can’t have nothing without something, they go hand in hand. Just like you can’t have objects without space between them or there’d be no thing, to differentiate something from nothing… So really, even nothing is something because something implies nothing. Nothingness is like the web of space that connects all things.
We hope you like the video and that your curiosity is piqued.
