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?

Dark energy. What is dark energy you ask? The definition of dark energy is “Whatever it is that is causing the universe to expand.”
