So I saw this image posted on Facebook and started the usual sci fi geek thinking of, “Well which would be cool …” and then thought. Wouldn’t it depend which universe you are in?
I suspect the T.A.R.D.I.S (The obvious choice BTW) wouldn’t work in a universe governed by the physics of Battlestar Galactica with its jump drive or Star Trek with its warp drives or the light speed of the Star Wars universe. And forget the Serenity, that whole universe lacks any FTL travel at all. Likewise I doubt any of the engines from the different universes would work in any of the others.
I am over thinking this right?
