Could you create another wormhole to come back?

  There’s no “through” a wormhole in the sense that you might immediately assume. The entrances are event horizons just as with a black hole; in fact it may be useful to think of a wormhole as more or less a black hole that appears in more than one place in the universe. To the extent that black holes and wormholes have an “exit” it would always be though another event horizon into another new causally disconnected space. As to if you could come “back” presumably no, or at least we lack the math to describe how going “through the looking glass” so to speak is anything other than a one way trip.
