I recently learned that the expansion of the universe means that everything is moving further away from everything else as new spacetime is fabricated between objects (rather than the universe’s edges expanding).
What I can’t find, is the process by which this expansion is happening. If the vacuum of space is considered spacetime, then spacetime can be devoid of all energy. So how does it get made if energy cannot be lost in its creation?

I don’t think space is being created. If it were being created then there must be a mechanism responsible (dark energy, dark matter?). I think it is just being stretched out. That is where the “Big Rip” theory comes in.
